How to Remove the Heater in a Washing Machine

Changing the heating element in the washing machine with their own hands

Automatic washing machines have long ago become an indispensable attribute of comfortable life of modern man. Older generations don’t even want to remember that once the laundry was washed by hand. And the new generation may not even know that it happens. And they don’t have to. There are “smart” home appliances for washing.

It works. we rest. Of course, everything is convenient and great. But this is the case as long as the washing machine is functioning without failure or malfunction. And they, unfortunately, are quite possible. Often, the problems and malfunctions may occur not even through the fault of the washing machine, but due to external factors affecting its work.

One such factor is the quality of tap water in our pipes. Hard water, moreover with different impurities, invariably leads to an increased formation of scale on the surface of the heating element.

Sooner or later it will cause its damage. And the instability of our electrical networks can put the heating element of the washing machine out of operation. Of course, you can wash with cold water, but the quality of such washing is unlikely to satisfy anyone.

What is the solution? You just need to replace the faulty heating element with a new one. In the service center master voiced the price, and you understand that it is expensive? We do not need such a master. We will carry out the replacement of the heating element on their own. And how to do this, we will consider further.

How it looks and works?

The heating element in a washing machine is a bent smooth tube with a conducting wire inside. Internal part is made of alloys with high electrical resistance. Changing the current parameter allows to regulate the intensity of heating.

Between the housing and the working element is a layer of material with high thermal conductivity. Between the contacts of the heater is a socket for the temperature sensor that determines the temperature of the water.

The heater can be sealed with a lip or collar to keep it in place. This must be taken into account when selecting the part. Instead of a heater without a thermostat you can install a heating element with a place for the sensor, but the hole will require a special plug.

Signs of heating element malfunction in the washing machine

Washing machine of any brand, whether Indesit, Ariston or Bosch, necessarily signals the breakage of the heating element. The main signs of heater malfunction:

  • Water is not hot during the wash cycle. If the water remains cold when starting a high temperature wash mode, it means that the heating element does not work. When the washing process reaches the water heating stage, the machine stops working and generates an error. At the same time, programs that do not need to heat water can work as usual.
  • Before the beginning of heating water, the technician “knocks out the automatic device”. disables the device, which protects the electric lines following it from burning. Failure occurs about 10-12 minutes after starting the washing program. This usually indicates a short circuit of the coil inside the heating element.
  • Machine knocks out the Ground Fault Circuit Interrupter (GFCI). The malfunction occurs just after turning on the appliance or just before heating the water. If the heating element insulation is defective, it may cause a current leak into the casing and trip the RCD.

If in the work of the machine is observed one or more signs of failure, perhaps the heater is out of order and requires replacement. To accurately determine the efficiency of the heating element allows checking with a special device. a multimeter, after which you can be sure of the malfunction and proceed to replace the heater.

How to change the heater in case of breakage

In order to make the replacement, no special skills are required, and in most cases, it is not difficult. For example, you can take a Samsung brand machine, in which the heating element is located in the back.

Before proceeding to replace the electric heater, you must unplug the machine from the mains.

In order to get into the washing machine through the back panel, the latter must be unscrewed and removed. With those models where the cover is located on the front, you will have a little trouble. In order to unscrew it, you will first need to remove the clamp that holds the collar. Based on its model, you will need to equip a screwdriver or pliers. To prevent the collar from interfering later on, you can wrap it inside the tank.

Now left to remove the top panel and the control board with the hatch lock. It is not necessary to take them out, you can just unscrew all the screws and put them in a way that they do not interfere. Next, the dispenser tray is removed, after which it is necessary to proceed to the bottom panel. After all this is removed, we will see the front wall, after disassembling which you can get to the heating element.

All wires are preliminarily removed from it, and unscrew fixing nut, which should be pressed inside and take out the heating element. On the heater will be a lot of scale, so you just need to replace it with a new one, and put all the parts in their places.

Owners of Indesit washing machines will help to change the heating element by the detailed step-by-step algorithm with photos, which is given here.

How to change a heating element in the LG washing machine

Failure of the heating element THEN is quite a common malfunction in washing machines. Tap water often contains a large amount of mineral salts, as a result of the constant heating of water element is covered with limescale, which significantly reduces its life. The water heater stops heating as a result.

If the heating element of your LG washing machine is out of order, we advise you to contact LG Service Department by calling 8-499-677-76-76 (for calls in Moscow and Moscow region) or 8-800-200-76 (for calls within Russia). LG Firm Service experts will quickly and qualitatively perform the repair of any complexity. But if you feel like a jack-of-all-trades and want to do it yourself to fix the breakage, we have prepared for you a step-by-step instruction on how to replace the heating element in the LG washing machine.

Replacing the heating element in the LG washing machine: step by step instructions

How to replace the heater element on a washing machine. Indesit

It is possible to change a faulty heating element in the LG washing machine without using the services of a master. The vast majority of LG models have a direct drive, which means there is no drive belt that could interfere with replacing the heating element.

  • Before you begin replacing the heating element, make sure your washer is unplugged. Turn off the water and disconnect the fill and drain hoses.
  • In LG washing machines, the heating element is under the tank, making it easy to change the heating element.
  • Remove the back panel of the washing machine (it is usually attached with screws or self-tapping screws).
  • You’ll see the outside of the heating element with the outer contacts at the bottom of the tank wall.
  • Remove the wires from the heating element. Before doing this, you can take a picture of their location on a smartphone, so that when you install the element in place, do not make a mistake.
  • Loosen the nut located in the center of the TEN, so that it is held on the end of the thread. Push it inside with the pin.
  • Now you can take out the heating element. It is easier to do this if you gently pry under the element with a screwdriver or knife. Remember that the element surface, contacts and seating are very vulnerable to mechanical damage, so proceed slowly and carefully.

How to install the heating element in an LG washing machine

  • Before proceeding to replace the element, prepare the seat by cleaning it of limescale and dirt.
  • Lubricate the seating and sealing surfaces and the element itself with any lubricant for technical parts.
  • Carefully place the new heating element in place.
  • Screw in the nut and tighten it with a wrench.
  • Connect the terminals and wires.
  • Assemble the body of the machine, then run the machine without laundry on high temperature mode. Verify if the new heating element in your LG washing machine is serviceable by touching the glass in the loader door after 15 minutes of washing: it must be warm.

To make the new heating element last a long time, it is necessary to choose a correct part. Carefully study the technical passport of the washing machine and determine the power of the element. For LG washing machines, the figure is usually 1900-1950 Watts, but for some models the power can be 2kW.

If for some reason you can not see the data in the data sheet, you can also find out the information on the heating element itself: it can be marked. Exactly these values will help not to make a mistake when buying and choose the part that will fit your LG washing machine.

You can buy a heating element in the LG service center, in a specialized spare parts store or in an online store. Specialists recommend not buying parts from the hands, and even more so second-hand.

Bosch

In a Bosch washing machine, the replacement of the heating element can also be done with your own hands. The repair process of a household product does not take too much time and is performed in this sequence:

  • Remove the top cover of the appliance by removing the 2 screws located on the back of the appliance.
  • Remove the dispenser tray from the front panel by pressing on the central latch.
  • Remove the screws on the control panel using a screwdriver.
  • Remove the bottom panel of the device, which usually only has latches.
  • Open the charging hatch and remove the rubber sealing collar.
  • Remove the screws that hold the door and the locking mechanism.
  • Remove the front panel.
  • Disconnect electric wires.
  • Remove the nut of the screw located between the electric contacts.
  • Press the bolt carefully into the tank.
  • Lift the gasket with a thin screwdriver to carefully remove the heating element from the tank.

The causes of the malfunction

TEN (commonly abbreviated to “electric tube heater“) is a metal tube filled with electrical insulator with good thermal conductivity. In the middle is a current-conducting (Fechromium, but more often nichrome) thread that heats up when connected to the mains. The heating element in a washing machine heats the water according to a program or a temperature set by the user.

The heating element is one of the most susceptible parts to breakdown in a washing machine. On the one hand, this is due to the periodicity of operation of the coil, which now heats up, then cools down. But the most frequent reason why the heating element stopped working is the deposition of limescale caused by the high hardness of water. A thick layer of scale causes a violation of heat exchange, the coil overheats and burns out. To replace the heating element in a washing machine is very simple and can be done at home by yourself.

Provide access to the heater

Before disassembling the machine it is necessary to deenergize it. To do this, you need to disconnect the power cord from the mains. You must also disconnect the machine from the water supply by turning off the tap and disconnecting the hose from it.

Having disconnected the washing machine from the communications, then you need to disassemble it. Usually the electric tube heater is in the back of the washing machine. To get to it, you need to remove the building cover. It is easy enough to remove, you just need to unscrew a few screws (their number is rarely more than 4).

Sometimes the heating element in the machine is in the front, and this situation is a little more complicated. It is not possible to remove the front of the housing immediately. the sealing rubber of the hatch (cuff) will interfere. Therefore, first remove the clamp securing the oil seal. To do this, you will need pliers or a screwdriver. The tool of choice depends on the type of clamp. For detailed information on how to remove the clamps, please see the material on replacement of the oil seal.

It is not necessary to remove the cuff completely, it is enough to detach it from the front part of the housing and set it into the drum so that it does not interfere with other operations. Having disassembled the cuff, then remove the door lock, which is fixed with two screws. The control box also has to be removed. To do this, you need to unscrew the two screws that fix the top cover of the washing machine. Having unscrewed the lid fasteners, slide it towards the rear of the machine to unscrew it from the grooves. Once you have done this, take the dispenser tray out of the hopper and unscrew the control box retaining screws.

The last thing to do is to remove the bottom plastic panel. It is held by latches or screws, depending on the model of the machine. It is possible that there will be screws behind the panel. they also need to be unscrewed. Now there is nothing holding the front of the washing machine and it can be removed.

Causes of failure and prevention methods

One of the main reasons affecting the life of the heating element is the quality of water entering the washing machine.

With hard tap water, lime deposits begin to deposit on the heating element. Plus, debris builds up on it, which reduces the heat output and makes the unit work harder and harder.

As a result, overheating occurs, which accompanies almost any washing cycle with water heating. A faulty heating element cannot be repaired, it can only be replaced with a new one.

In order to prolong the life of the heating element, it is recommended to clean the washing machine every few months. One of the available options is with citric acid. It is simply poured into the compartment for laundry detergent and run one of the modes at high temperature.

Preventive cleaning will help to clean not only the heating element, but also other elements of the washing machine. On how to clean the washing machine from scale with citric acid, you can learn here.
