The gas column lmax does not light a spark is there. Gas boilers Lemax: Review…

Why rogue and how to turn on the gas boiler lemax

There are several possible reasons why the Lemax gas boiler goes out, or does not start at all:

  • A gas leak is recorded. In this situation, it is necessary to immediately open the windows wide open, block the gas, and the device itself is turned off. You also need to call the emergency service specialists.
  • Insufficient thrust, a burner clogged. The signal will be a red shade of the spin, lengthening the reeds and their smoking. Eliminate the reason for cleaning the chimney, burner.
  • With other difficulties with a chimney and a thermostat, the main burner can involuntarily turn off involuntarily.
  • There is no water circulation. With the existing pump, the wrong bias of the pipelines can be exhibited.
  • The gas was turned off. In this case, the equipment will turn off spontaneously.

Lemax gas column does not light up the first time. elimination of the malfunction

There are many reasons for this problem. We will consider the most common of them in this article.

First of all, you should check whether the gas valve is completely open and whether there is cold water in the water line. Lemax gas column may not ignite due to the fact that there is no spark for ignition due to the fact that the batteries sat down, if you use them, or poor contact on the power supply if you connected the power from the mains.

Lemax columns have a combined power source, they work both from the network and from batteries. Replace the batteries, check whether the contacts in the battery compartment are oxidized, and whether the contact on the power supply is good.

Low water pressure is also the cause of the inoperability of GVN. If the highway is constantly low, the pump installation will save. Can clog a capture filter on the input tap pipe, or the mixer on the crane.

To eliminate, rinse the filters with a brush with a rough bristle under a strong stream of water. If it is not possible to do this due to the boiling of the scale, they should be placed in a solution of citric acid, it is prepared at the rate of 100 grams per liter of water, or change to new.

The lack of traction can also be an explanation of why the gas column lmax does not light up. You turn on the column, but it immediately fades, due to the fact that the traction sensor is triggered. This happens if the duct is packed with soot, or an extraneous item got there.

Check the traction, bringing a light match, a candle to the chimney, if the fire does not deviate towards the chimney, then it is clogged. Cleaning the channel will help get rid of the problem. In addition, the traction sensor can work and turn off your unit and in the absence of natural traction, if the windows and doors are tightly closed, opening them, you will eliminate the problem.

The appearance of the gaps between the duct pipe and the pipe, between the tribes of the pipe. Street the gaps that appear. The gas knot was clogged. if this happened, it is better to invite a gas service specialist. Yourself you can only clean the burners of the burner, remove the dust from the mixing chamber in Lemax is problematic, since it is difficult to get inside it due to a not very successful design.

The dust is removed by a soft brush or a rag, a corporal from the nozzles. using a brush with a metal bristle. After cleaning, you should check all the joints for tightness with soap foam, soaping them. If she bubbles, then the connection was disturbed. To clean the snot and the air channel of the panel burner, call the Gorgaz service.

Low gas pressure also causes why GVN does not turn on the first time. Perhaps somewhere there was an accident, but most often, in this case, the pipes of small diameter are guilty, which connects the gas line to the GVN. Gas farming specialists should be called for the installation of pipes of the corresponding diameter.

High pressure is also the reason why the column does not ignite. Installation of a lowering gearbox will solve this problem. In addition, if you have an insufficiently high pressure of water or GVN gas adjusted to maximum values, attenuation will also occur. Correct this is possible by adjusting control handles.

Wear of the rubber membrane in the water block, it can break, stretch out. Remove the device case by unscrewing the two screws at the bottom of the unit, then remove the display and temperature sensor. Pull on yourself and up. In the water block, inspect the membrane, if it is damaged, it is necessary to replace it, it is better to buy silicone, it will last longer.

External factors

Often, ignition functions with interruptions due to scarce pressure of water in the tap. This is easy to fix by adjusting the pressure level on the water supply sensor. Sometimes the cause may be poor water supply, which is why there is a non-compliance of the water pressure in the tap and minimal bandwidth of the column. In this case, the installation of a special pump that increases pressure will help. Cleaning the cleaning of the filter water supply systems into which dirt falls, internal deposits will correct. The mesh filter located immediately in front of the water knot is also subject to cleaning.

To check sufficient gas pressure on the highway, it is enough to light the kitchen slab. If the flame burns, the reason why the gas column does not work, there may be a clogging of the filter built into the design.

IMPORTANT! If the problem is related to the gas supply system, then it is dangerous to engage in independent repair. It is necessary to turn the gas supply valve, preventing the leak, open the windows, and then call the emergency service. Only specialists should eliminate problems with the gas pipeline!

Most modern water heaters have built.in sensors, so that in the absence of traction, gas supply blocker is triggered. You can find out if there is a thrust, you can independently. To do this, you must bring a lit match to the chimney. If the flame does not sway, then the probability of clogging of the duct. Only professional workers will be able to inspect the collector and its further cleaning. The installation of plastic windows can significantly affect the circulation of air of the dwelling, which will reduce the traction.

Internal breakdowns and blockage

With the absence of a characteristic crackling, you should pay attention to the good work of the litter. If there is no spark generation, it is necessary to clean the fuse, since the nests of the burial burner with constant operation accumulate a layer of soot. The installation of a gas filter will help reduce the likelihood (or repetition) of a similar problem.

Due to the blockage or rust inside the rostal pipes, the water pressure will fall, so the ignition will function poorly.

The mesh water filter can be removed independently, then rinse, or replaced if the pollution is plentiful. The gas filter is located in front of the device, for cleaning it there is no need to disassemble the system, although it is still better to entrust working with gas elements to an experienced master.

Over time, a scale forms inside the heat exchanger system and will lead to the fact that the water heater will cease to turn on. For cleaning, the structure is connected to a flushing installation, after which the scale is removed. Many rinse the heat exchanger on their own using citric acid. This method, in addition to removing the scale, can damage the copper elements of the system.

Gas column malfunction: no spark

Consider one of the first and most frequent problems of gas states, as a weak spark discharge or its absence. Such a malfunction of the gas column is quite common and it does not appear after a year or two after using the equipment, but after a few months.

Symptoms, as a rule, are the following. Yesterday, the gas column worked like a clock, but today it suddenly did not turn on. You close the hot crane, open it again. the column earned. Then every day such manipulations have to be done more (opening. closing the crane). And finally, the moment came when she completely stopped working. Then only call the master or eliminate the malfunction with your own hands.

Malfunction of the gas column and cause

Removing the cover of the gas column and opening the crane, you see that there is no spark discharge. So why is the spark disappeared, with which the malfunction is associated?

A reason not related to the failure of any detail. one.one. Insufficient water pressure.

To get started, check what position the temperature control handle is located, which is responsible for the water flow pressure at the entrance to the gas column. At low pressure, the column will not turn on. Turn the handle counterclockwise to the end. in the extreme left position, and then open the tap. If the column has been earned, probably in suitable pipes, a weak pressure and the reason should not be sought in the column.

one.2. The appearance of scale in the radiator.

When using hard, lime water on the walls of the heat exchanger, scale may form, which also affects the creation of the pressure necessary for the operation of the gas column. To eliminate the scale, you need to remove the heat exchanger, I note that you have to make out almost the entire column. Prepare a 10 percent solution of citric acid: stir 100 grams of lemon in one liter of warm water. Pour the heat exchanger into the tubes and leave for 15 minutes. Drain the solution and rinse thoroughly with water. It is recommended to clean at least once a year.

Diagnosis and immobility of the rod.

On a rod located next to the microswell. This, in turn, affects the mobility of the tongue and the closure of the discharge of the contacts of the circuit. To clean the rod, you need to remove the microswell and release the motionless tongue.

Violation of the electrical circuit between the micro.plane and the control unit.

Also, a gas column malfunction associated with the absence of a spark can be caused by a violation of the circuit between the circuit breaker and the control unit. To do this, check the terminals connecting them and the wires of the switch. Perhaps oxidation of contact places.

Phosgene is a toxic gas prepared by the reaction of carbon monoxide with chlorine: \mathrmCO(g)\…

Microe malfunction.

Switch. consumable, fails quite quickly. Fortunately, replacing it is easy: disconnect the terminal and unscrew two screws.

Malfunctions that are less common, this is the failure of the electromagnetic valve and the electronic control unit. We will consider them in a separate article.

Possible breakdowns and their repair

The boiler refusal is not always associated with inaccurate settings or external reasons, but almost always the malfunction can be eliminated independently.

All SIT boilers have a similar structure, it is reliable and convenient to set up, almost all units are available to a simple user

Turn off the boiler before any repair, let it cool completely and redraw the gas supply on the riser. Even if you have only burned a litter, the risk of burning is very high.

Damage #1. failed thermocard

According to the instructions, if the boiler with SIT automation does not turn on, the problem should be sought in the thermocouple and only in it. Thermocouple is a flame control sensor that provides gas overlap when attenuating the burner.

When igniting, you need to keep a hand.pressed handle or a special button precisely in order for the thermocard to warm up from the flame and fixes the electromagnetic valve in the open position.

However, there are a number of situations when this protection system works erroneously:

  • fire does not fall on the thermocouple sensor;
  • The sensor was smoked, oxidized, polluted;
  • The copper tube of the thermocouple has burned out or no longer conducts electrical impulses;
  • The thermocouple in the adapter to the gas valve is not well twisted enough.

In the boiler, this part is not difficult to find: this is a red, copper tube, one end of which is screwed into the control unit, from below, and the other into the panel near the faint and piezo.Zhizhiga.

First of all, try slightly tighten the mounting nut to automation. Bad contact may be the reason for the refusal of work. Gently twist the lower end of the thermocouple, which is heated by a flame.

As a rule, all the nuts on the panel with a pilot burner are unscrewed by a 10 key, and the panel itself with a cross blade

Inspect the sensor and clean it with a dense fabric or the thinnest sandpaper. Twist in place and try to start the boiler.

Did not help? Look through the window whether the flame from the litter falls on the tip of the thermocouple. If not, bent it by unscrewing the panel on 2 bolts, or adjust the flame of the pilot burner, as we described above.

In the presence of a multimeter, you can independently check the operability of a thermocouple. To do this, you need to unscrew both its ends and pull out the part from the boiler. At the end that is screwed into the automation unit, you will see a lead tip that transfers the charge to the gas valve. Clean it to shine.

Place the thermocouple sensor so that fire falls on it from the burner of gas stove or dry alcohol tablets. Close the multimeter sensors on the lead tip and on the copper tube of thermocouple and measure the voltage. If everything is in order. look for a malfunction further, and if the problem is in a thermocouple, you will have to purchase a new part.

Damage #2. the traction sensor works incorrectly

The traction sensor is installed at the base of the chimney and is designed to block the gas supply, turning off the boiler if the combustion products cease to be displayed.

The traction sensor is located under the top cover of the boiler. in the part where the combustion products are most concentrated before removing into the chimney

Otherwise, it is possible to poison the residents of the house with carbon monoxide, so this protection system is mandatory in all gas boilers.

In the energy.dependent boilers of the Lemax brand, the sensor is connected to the adapter, which is attached to a thermocardor to a gas valve. If its circuit opens, the electromagnetic valve covers the fuel supply, and the boiler is turned off.

If the design is provided by the overheating sensor, it is also included in this chain. Accordingly, with a non.working sensor, the launch of the boiler is impossible: the gas supply will be carried out only with a pressed handle or a special button.

The sensor itself is rarely out of order, usually problems are caused by poor contacts and wires. First turn off the contacts and clean them with a dense fabric, solvent or alcohol. Inspect the integrity of the wire and their insulation, if possible, call the multimeter if the conductivity is broken. replace.

Dry the purified contacts, insert them into place as tightly as possible, the wires to the sensor itself can be soldered. Try starting the boiler.

If the situation has not changed, try to close the contacts on the adapter to the gas valve, wrapping them with wire.

The traction sensor in the lemax boilers is connected to the adapter between the thermocouple and the gas valve, at the bottom of the automation

If this helped, and the boiler has earned-it means that the problem is still in the traction sensor. Do not leave contact with a closed for a long time. it threatens your safety! Replace the sensor or call a specialist.

Damage #3. clogging of the nozzle

It happens that when trying to turn it on, even the wick does not light up and a gas hiss is not heard, that is, nothing happens. This behavior of the boiler surely indicates that the nozzle or injector of the smaller burner has clogged.

To figure out how to light the Lemax gas boiler pilot, disconnect the tube going to it from the automation unit. On the panel of the burner, the gas supply tube is the average of 3 connections, for convenience, you can first unscrew the thermocouple.

Nozzle supplying gas with a thin stream can be the end of this tube or a separate part. Cleam the nozzle of the nozzle with a toothpick and blow the tube, making sure that the air passes.

Remove the panel on which the tube was fixed by unscrewing 2 screws on the sides. You will see a mesh on the gas supply tube. air is taken through it for mixing with gas.

Given that the air supply goes from below, along the floor, and homemade pets love to bask near the boiler, this mesh can clog with dust and wool, which does not always burn out. Blow this net. only without fanaticism.

If necessary, the pilot burner can be replaced with the panel. but it is better to entrust this to a specialist who will correctly put and set up equipment

How to eliminate malfunctions and breakdowns in the gas column Lemax

Please tell me why the spark is lost when the Lemax turbo column is launched? There was a break in the thermocouple wire. Connect the wires correctly. Damage to the carrier. It is required to check this element and adjust. The electrode is broken. Change it to a new. Violation of the Alpha Euro column in the work. I’m trying to start starting, the spark is visible, but the fabric settles do not appear. What is the problem? The nozzle of the carrier clogged. Wash. The firing electrode was in the wrong position. Set it down. There is air in the gas network. Remove air. There is the same gas water heater. Because of what can go out the smell at the time of ignition. What a malfunction? The thermocouple is inoperative. It should be replaced. Coil damage. Change it. A question arose for the work of the water heater. The situation is as follows: the smell burner burns normally, but the main burner does not function. What to do and how to fix it? The water pressure is too low. Adjust the recommended pressure in the system. To do this, we recommend turning the regulator to the right to the right. Wear of the membrane. Change it. In a private house I use a gas water heater Lemax. If you suspend the flow of water, then the burner does not rot. What is the source of the problem? There is a clogging of the gas valve damper. Conduct his check. If required, clean. The piston or a gydroclapan rod in open state happened. Remove the components, clean, replace if necessary. Check gas supply pressure. Set up if necessary. Replace the gearbox of the gas cylinder. What is the reason that the ignition is delayed, and the gas.air device claps loudly? The fire of the smaller does not reach the main burner, or it is unstable. A smell and nozzle should be cleaned. Then perform the adjustment procedure. Tell me, please, the gas column Lemax alpha 20m, the wick is lit, but the device itself is not. What could be? The pressure of water is good. Most likely, the membrane of the water part is worn out. It is necessary to replace it. Gas column Lemax turbo 24. The burner lights up the first time and rises after 2 seconds. Then it lights up only from the third time. Water heats as usual. The spark is normal. The wick lights up immediately. What could be the problem? Replacing the flame ionization sensor will help eliminate such a malfunction. Water heater Alfa Euro 20. During operation, a strong flow of hot air beats up due to the back wall. The wall is very heated and the plastic extract of the hood over it melted. There was no such thing before. It is necessary to conduct annual maintenance. The heat exchanger of the column is packed with soot. Please tell me what is the cause of the malfunction? Lemax turbo column 24 works only with the minimum level of water supply regulator. There may be two options: the membrane is worn out. Low water pressure. Something incomprehensible is happening with the Alfa Euro 24 gas column, we do not understand what’s the matter. In general, the water does not properly heat up, the maximum temperature is 30 degrees, with maximum supply of hot water. If the water supply is reduced to the minimum, then the maximum can be heated to 37. The pressure is enough, the batteries were changed twice (Energyzer), as well as the strangest behavior, if the right handle is turned towards reducing clockwise for 2 hours, then the device is ignited by itself, while we don’t turn on hot water, there is no water, it is just lit, and gas is on idle, while the temperature sensor shows about 80 degrees. Also, if you twist the right handle to the minimum mark, there is a noise of water with a large pressure in the water heater itself. How can this be? You just need to contact a qualified service. In my gas water heater, Lemax turbo 24 sometimes does not work electrores. Gas supply is present, new batteries are installed, but at the same time, when I open the hot water crane, the device does not turn on. What could it be? There may be several reasons. too weak pressure. The reverse traction is present. Breakdown of the microswitch responsible for the ignition. In general, if you understand electronics, I would advise you to remove the casing, and at the time of supply of water, check the voltage on the batteries. Perhaps even new batteries give too weak a signal. It is also necessary to check the serviceability of all sensors. Or call the master, since still the column refers to gas equipment, and all manipulations on it need to be carried out with extreme caution. Any unskilled intervention can lead to gas leak, explosion and people can suffer. The membrane can also be damaged. Alpha euro 20 gas column broke. And before she worked without problems, but a few days ago she stopped warming the water. The maximum temperature is 25 degrees, provided that the power lever is set to the extreme maximum position, and the duct is installed at a minimum. I washed the radiator, cleaned the main burner, also sorted out the water knot. What could it be? Perhaps you have decreased the pressure of the incoming gas. This is especially critical if the device is connected by a thin hose. The gas filter could also clog. There may still be many options for breakdowns. As I remember, this model allows you to regulate the pressure of gas in front of the nozzles. But still, I would advise you to call a service specialist. The device does not light up the first time. the path of solving the problem. first you should check if the gas crane is completely unscrewed, and whether there is a centralized CVS. The gas column Lemax alpha euro 20/24 kW may not immediately light up as a result of the absence of a spark, in turn, the absence of a spark may be due to the sowing batteries or a weak contact on the power supply, if the power supply is connected from the electric network. These models have a mixed type of power, they can work both from the mains and batteries. You will need to replace the batteries, check the contacts in the battery department for oxidation, in addition, you need to make sure that the contact on the control unit is serviceable. A weak stream can also be one of the reasons for the incorrect operation of a gas water heater. If the central system has weak pressure all the time, the problem can be solved by installing the pump. The filter that is located on the water pipeline pipe, or the mixer on the valve, can also clog. To solve this problem, you need to rinse the filter under strong pressure, for this you need a brush with hard wool. If you do not go out to do this because of the stabbing, then place them in a solution with citric acid. The method of preparation is as follows: 100 g. for 1 liter. water. Or replace with new. Bad thrust or its complete absence can also cause not ignition of the gas column Lemax alpha euro. You start the water heater, but it will rotate immediately, the reason for this is the trigger of the traction sensor. This happens with a clogged air duct. The thrust is checked with a match or candle, for this, bring a candle to the chimney if the flame does not deviate in the direction of the chimney, this suggests that it is clogged. The solution to the problem here is obvious, you just need to clean the channel. In addition, the traction sensor can harden and turn off the device and in the absence of natural thrust, if all windows are closed in the room where the device stands, open them for a while, thereby you can eliminate the problem. The occurrence of gaps in the interval of the duct of the duct and the pipe, between the knees of the pipe. It is necessary to seal the resulting gaps. Blocking the gas node. if this happened, it is recommended to seek help from a qualified specialist. Yourself you can clean only the holes of the burner, it is difficult to get rid of dust from the mixing chamber, because it’s enough not just to get into the inside due to the complexity of the structure. Dust can be removed with a soft brush or rag, butt with holes. with a brush with an iron chin. After completing the cleaning, do not forget to check all the connecting places for tightness, for this you need soap foam. If the bubbles appear, this suggests that a violation of the compounds occurred in this place. In order to clean the snot and the air burner air channel, it is necessary to call the corresponding service. Low gas pressure can also cause that the device does not light the first time. Probably, an emergency situation occurred somewhere, but often, in such a situation, the cause of this problem is the pipes of inappropriate diameter, to which the gas line is connected to the water heater. In this case, it is necessary to contact the gas service in order for them to install pipes suitable in diameter. Excessive pressure can also cause not ignition. The problem can solve the installation of a reducing gearbox. In addition, if your device with low water or gas pressure is configured to maximum value, attenuation will also occur. The problem is solved simply. it is necessary to adjust the control handles. The unsuitability of the rubber membrane in the water block, it can be worn out, to tear. Remove the sheathing of the device, for this you will have to unscrew 2 screws from below, after which the monitor and temperature sensor are removed after which. Pull over yourself and then upstairs. In the water block, it is necessary to conduct a visual inspection of the membrane, if it is deformed, then it should be replaced, it is recommended to purchase silicone, its service life is much more. Violation of the connections at the site of connecting the electric nurse with the ion sensor of the flame, EMC of the smallers. It is necessary to check the installation sites, clean the contacts if they are oxidized. With a breakdown of EMC or electronic node, their replacement is required, because these components are not repaired. If the gas water heating column Lemax alpha does not turn on initially or after prolonged downtime, air accumulation could occur in the tubes. To solve such a problem, open the hot water supply valve for several minutes, close, and open it again, you need to repeat these actions until all accumulated air comes out of the pipes, and the smell burner will not light up. Another possible cause can be called the oxidation of the rod. In order to eliminate oxidation, you need to disable the microswitor, dismantle, clean and grease the stem. Incorrect adjustment of the carrier for gas pressure in the gas pipeline. The electrode in the device is so that the spark enters the comb, it is fixed on the edge of the gas burner. If the supply is adjusted to low pressure, the gas enters a small volume and at low speed. As a result of reverse traction, the gas goes down without reaching the spark. You can solve the problem by bent the electrode to the level so that the spark does not fall on the comb, but in the middle of the burner.

The problem can solve the installation of a reducing gearbox. In addition, if your device with low water or gas pressure is configured to maximum value, attenuation will also occur. The problem is solved simply. it is necessary to adjust the control handles. The unsuitability of the rubber membrane in the water block, it can be worn out, to tear. Remove the sheathing of the device, for this you will have to unscrew 2 screws from below, after which the monitor and temperature sensor are removed after which. Pull over yourself and then upstairs. In the water block, it is necessary to conduct a visual inspection of the membrane, if it is deformed, then it should be replaced, it is recommended to purchase silicone, its service life is much more. Violation of the connections at the site of connecting the electric nurse with the ion sensor of the flame, EMC of the smallers. It is necessary to check the installation sites, clean the contacts if they are oxidized. With a breakdown of EMC or electronic node, their replacement is required, because these components are not repaired. If the gas water heating column Lemax alpha does not turn on initially or after prolonged downtime, air accumulation could occur in the tubes. To solve such a problem, open the hot water supply valve for several minutes, close, and open it again, you need to repeat these actions until all accumulated air comes out of the pipes, and the smell burner will not light up. Another possible cause can be called the oxidation of the rod. In order to eliminate oxidation, you need to disable the microswitor, dismantle, clean and grease the stem. Incorrect adjustment of the carrier for gas pressure in the gas pipeline. The electrode in the device is so that the spark enters the comb, it is fixed on the edge of the gas burner. If the supply is adjusted to low pressure, the gas enters a small volume and at low speed. As a result of reverse traction, the gas goes down without reaching the spark. You can solve the problem by bent the electrode to the level so that the spark does not fall on the comb, but in the middle of the burner.

Electronic control boiler

The Lemax boilers line, which are connected to the 220V network, is actively expanding and now includes the wall.circuit models Prime, as well as the floor Clever and Wise.

Unlike imported competitors, whose management payments are often burned out due to changes in the mains, these devices are designed to work in networks.

Wall boilers, as a rule, have a built.in circulation pump, expansion tank and significantly more control and protection systems

However, such models can sometimes fail.

To ensure security, the main protection systems are still mechanical:

  • The thermocouple controls the burning and overlaps the gas if the burner is extinct. the E1 error;
  • The traction sensor gives a shutdown signal if the combustion products are not diverted. error E3;
  • The membrane gas valve will block the supply of fuel if its pressure drops below critical, or the gas is turned off on the network. E1 error;
  • The thermostat of overheating controls the temperature of the heating circuit, when overheating, it turns off the boiler with an error E2.

A colorless, odorless gas in a tank needs to be identified. The gas is nitrogen \left(\mathrmN_2…

All these systems are arranged in the same way as in boilers with mechanical control, and their location depends on the model. Therefore, we will not re.describe the check and repair of each node, and the instructions for it will help you to find them in our boiler.

In addition, the boiler with electronic control does not start if it discovers a malfunction of any of its boards or sensor, or their unsatisfactory indications. for example, low water pressure or power voltage less than 170V.

So that the entire boiler does not have to be sorted out, the error code and its decoding in the instructions will indicate the location of the malfunction.

To configure and repair electronic controls, it is better to contact a specialist, he can weave, reflash or replace the fee

If the boiler does not react at all to an attempt to turn on, even the screen does not light up, most likely. the problem with the power supply. No matter how trite, check if the fork is included in the outlet, whether the machine is raised, is there any light in the house.

A child could pull out a plug from a socket, and the machine could turn off the voltage difference, so do not neglect this advice.

If everything is normal with power supply, and the boiler display does not light up, call the service for diagnosing and repairing or replacing electronic control elements.

Problem with a water duct

Often the column does not ignite when the water is turned on due to a decrease in the water duct. With such a malfunction in the tap, a water jet of water when turned on is very thin, weak. There is a feeling that the gas column is faulty in appearance. This happens in absolutely any brands: Neva, oasis, Bosch (Bosch).

Reducing the water duct can occur:

A sharp loss of the gas column can occur due to street work. At this time, they can repair a street water supply. Accordingly, the total pressure of cold water will be sharply reduced everywhere. The owner can easily miss this moment and look for the reason in the gas column, analyzing it. The reason lies on the surface, and a person confuses and searches for it in a completely different.

Also, water pressure in the gas water heater may gradually decrease due to banal pollution of the aerator intended for the mixer. To exclude the cause of the malfunction associated with the aerator in the tap itself, it is necessary to remove it and clean it.

This is a typical aerator that is installed on the mixer. Try to clean it

Owners with a mesh filter at the input should also not forget about it and periodically cleanly clean.

Carriage filter. It is installed on the supply of cold water to the column. Clean it the same

The flask filter can also cause a gradual reduction in water pressure in the gas column. It is worth not forgetting about it and, first of all, when the wick of the gas column does not ignite, pay attention to this. If you miss the reason that lies on the surface, there is a risk of investing in unnecessary diagnosis or repair of a gas column. Repair and diagnosis of a gas column, in this case, is not appropriate.

Two filters for water purification in flasks. They can also clog

There is another case associated with the absence of water pressure when the gas water heater is turned on. This happens due to mechanical hose clogging. Okhalin was found in the hose, and she blocked the path of water. Okhalin could go from the heat exchanger.

There are two regulators in the gas column. One is responsible for the regulation of the flame force, the second is responsible for the regulation of water flow. The lower the regulator occupies, the at a lower pressure the column may work.

There is not enough charge

When opening water, you observe a normal flow, when turning on, there is a characteristic click, a spark is formed and everything is generally visually good. But there is one noticeable moment: the burner itself in the gas column does not ignite. If you look at the window, then there is no flame. It is for this reason that there is no hot water. The owner has no hot water, because of this fact there is a lot of inconvenience. This reason must be eliminated as soon as possible.

The reason for the malfunction and lack of hot water lies in a completely simple phenomenon. When the battery is stopped, the column ceases to function. It does not heat up and, therefore, the supply of hot water stops.

Battery of batteries in the last stages is enough only for the formation of a spark. Therefore, you visually observe a spark, there is a noticeable click. But the energy of the battery is not enough to ignite the burner itself.

It is not difficult to replace the batteries yourself. To do this, open a box with batteries and pull them out of there. Next, you should replace new high.quality powerful batteries.

about batteries

Polarity in batteries matters. If you insert the batteries, not taking into account their polarity, then the column will not light up. Batteries can sometimes get stuck in the block, so you should follow them.

Replaced by new functioning batteries subject to two main criteria:

Batteries used in gas columns should be standard D (differently, batteries-batch. Salt options are not suitable, because they have the ability to quickly fail. In most cases, alkaline batteries are used for gas columns. They are called alkalin batteries differently.

There are often cases when a person acquires batteries, and they do not light a column. Several questions also arise here, why even new batteries cannot cope with their functions. At this stage, the owner can also be embarrassed and look for the reason in a completely different. In order not to be in such an unpleasant situation, it is necessary to approach the choice of batteries for the functioning of a gas column. Several tips should be taken into account.

Tips for choosing batteries

  • It is not advisable to choose too cheap. In this case, it is recommended to choose the batteries more expensive (normal are about 200). If you purchase cheap. then they most likely will not work normally, which means that in the future it will be necessary to overpay. Therefore, get the initially good high.quality expensive batteries;
  • Pay attention to the shelf life of batteries;
  • As for brands, preference is given to the brands Duracell and Energizer.
  • The battery should be alkaline or lithium.

If you have nothing at hand, and you want to check the operability of the battery, then it is enough to throw them a little. An unexplored battery will bite a little from the table, the charged battery of such a phenomenon will not be observed. But this is a pretty conditional method.

The use of a certain multimeter tester that determines the charge will be more informative. Everyone will be able to use such a tester, it will not be difficult. This method is convenient and practical to use, and you can purchase a tester for batteries in any store.

A diaphragm of the gas unit

Another of the reasons why the column does not turn on, there may be damage to the diaphragm of the gas unit. The diaphragm of the gas unit regulates the gas flow into the burner depending on the pressure of the water. Entering the case, the water presses on an elastic diaphragm. behind which there is a gas valve rod. The greater the pressure, the more the valve opens and the more gas enters the burner.

If the diaphragm has mechanical through damage and water enters the cavity of the rod, then the pressure on both sides is aligned, and the valve rod remains in place without movement. This is one of the reasons why the gas burner does not light up. You can solve the problem by removing the block and replace the diaphragm with a new.

Tip: When choosing a repair kit, it is recommended to pay attention to the silicone diaphragm. Unlike rubber, it is more elastic and has a larger resource of “turning on-off” cycles than rubber.

After replacing the diaphragm, it is recommended to make an audit and threaded joints of the column, replacing all gaskets and seals in the valve group.

Electronics failures

The presence in modern models of a large presence of electronic components on the one hand ensures high safety of the device and ease of use, on the other hand, complicates the search for a malfunction and subsequent repair.

The causes of the electronics malfunction are mainly related to the influence of external factors. voltage drops in the network, thunderstorm discharges that have fallen into main gas pipes and getting on the water board from leaks inside the device. In addition, it is impossible to exclude fails of individual electronic components due to failures in the electronics itself.

The reason that the gas column of the vector does not light up may not be a malfunction of the electronics, while the following situations may occur:

  • Lack of sparks with ignition;
  • Extinguished digital scoreboard;
  • The device does not start the first time;
  • When working, it constantly shows an alarm;
  • Protection systems are constantly being triggered;
  • The device either turns on, then goes out again;
  • Diagnostics of the breakdown usually begins with the test of batteries, old or discharged batteries must be replaced with new. If there are traces of the electrolyte output to the terminals, you need to clean.

If this operation has not led to the elimination of the failure of the device, it is necessary to call the wizard to check the electronic unit. Most often, in such models, the electronics unit cannot be repaired, it is simply replaced by a new. During the replacement of the unit, the master must examine all the nodes of the device, and when connecting a new unit, in addition, testing the system and setting up its parameters. Particular attention is paid to the presence of leaks in the places of compounds of the nodes and the integrity of the heat exchanger.

Causes of problems with the launch of the column

To identify the malfunction and eliminate it, it will be necessary to analyze the operation of the equipment. Masters pay attention to the following signs:

  • There is no spark from piezoelectric element or a fulfill does not work;
  • The burner is lit, but not the first time or periodically goes out;
  • a water regulator (frog) leaks;
  • The column turns on with cotton.

In normal condition, the water heater works almost silently and works with a delay of not more than 1-2 seconds after the opening of the water clearance point. Below are the main features that help diagnose the cause of the breakdown and methods of eliminating the malfunction.

Piezo element does not give a spark

One of the common problems. The malfunction can be expressed in several manifestations:

  • There is no spark in the gas column. the reason: the failure of the piezo element, the electrode or its displacement. Such a malfunction is observed in cases where the piezoelectric element does not turn off (approximately 30 seconds.). After that, the smell wick goes out. Repairs, if piezorodzhig does not work, consists in replacing the node.
  • There is a spark, but the column has ceased to ignite. the reason, elementary non.compliance with operation rules. Before pressing the button, you need to hold a pressed gas handle for about 10 seconds. There is a security system inside the water heater. Until the smells of gas supply to the burning device will be blocked. 10 seconds on the supply handle are usually enough to light the wick. If the piezoelectric element does not work, although the spark is present, the manufacturer’s instructions should be re.read and the wick is in accordance with the above instructions.
  • The wick does not burn. the breakdown is associated with the failure of automation or insufficient traction in the chimney. The cause of the malfunction also becomes a contaminated smell, which needs to be cleaned. When burning gas, soot settles on the device. The spark is present, but the wick stops burning immediately after turning off the forced gas supply. Shirder cleaning (you need to serve every year) will help to eliminate the malfunction.

Replacement or adjustment of the piezoelectric element requires the availability of the necessary tool and appropriate skills. It is better to use the service workshops for repair for repair, or invite masters at home.

Mixing cold water in the mixer

Many people, instead of adjusting the degree of heating on the gas column itself, mercilessly tormented the mixer. If you open cold water too strong, then the lit column simply goes out. If at that time she did not burn, then she will not light up. Take the rule to turn on the first water water, and only then. the supply of cold water. And best of all, adjust the degree of heating using the appropriate regulators.

It must also be remembered that intensive mixing of cold water is not welcomed by the developers of gas columns. this can lead to their damage.

Electronics malfunction

The traction sensor in gas columns is usually located on top. He is attached to the smoke ere.

Modern gas speakers have on board many electronic blocks and sensors. they are not only in the simplest models. I control the traction and the presence of flame (ionization control) sensors, monitor the temperature of the water and automatically adjust the degree of its heating. If one of the sensors fails, then the gas column will work with failures. The most characteristic malfunction is the breakdown of the traction sensor in the exhaust gases collector. As a result of this, electronics will not give the go.ahead for roser. Damage is also pursued by electronic modules installed in many gas columns. And their repair is complicated by the fact that this requires special knowledge in the field of electronics and circuitry. If you are sure of the malfunctions of electronic nodes, but do not have the necessary knowledge, feel free to call the master.
