Causes of the washing machine does not drain may be a faulty drain pump, pressostat, control module or clogged drain path.
Drain pump from 1500
The pump breaks because of debris that slipped through the filter and got into the impeller or wrapped around the shaft. Pump motor fails or impeller breaks. In the first case, the pump does not work at all, in the second. the damaged pump rattles, rattles, but the machine pumps out water poorly, does not drain at all and hangs with water for washing or rinsing.
Faulty pump is replaced with a new one, it can not be repaired.
Drainage circuit clogging from 1000
Water from the tank runs through the spigot, filter, pump, drain hose. Any part of the drain path can become clogged. The situation with the filter and pump we have already considered. In the nozzle most often stuck small things that slip out of the tank, as well as accumulation of coins, metal objects, tissues and papers. The clog collects inside the nozzle or at the volute connection to the tank. Hose is clogged with fabric debris, hair, paper shavings from disposable handkerchiefs caught in pump.
The master will check the drainage system and remove the blockage. If the pump is broken because of debris, it will have to be replaced with a new one.
Pressostat error from 1500
Water can remain in the machine due to failure of the pressostat, which controls the level of water in the washer. This happens when the level sensor is stuck in the “empty tank” position. Control module receives a message that there is no water and stops the drain.
The technician will determine the cause of the malfunction and repair or replace the sensor.
Control box from 1800
The washing machine sometimes stops draining due to the breakage of the control unit. The cause is damage to the circuit board in the area that controls the pump. Most often the radio components and tracks are burned out, sometimes the contacts of wires to the pump are loose.
The master will check the unit and say what needs to be done: repair of the board or replacement. In the case of repair, the burned elements are restored, the tracks of the microcircuit are soldered.
Parts are not included in the price and must be paid for separately.
Replacing the faulty part
Remove the pump in the step-by-step sequence described above. Examine the pump in detail and determine whether you need a complete replacement of the washing machine pump or the volute can be left.
Before installing the pump, it is necessary to clean dirt from the volute and the seat of the pump. Then the pump is screwed on, and the spigots are connected.
A new pump is selected according to these indicators:
- Method of attachment. on bolts or snaps.
- Contact arrangement. front or back.
- Connection to the network. by terminals or chips.
- Capacity. from 19 to 20 W.
How to repair the pump of the washing machine with your own hands. the whole process, as in the palm of your hand!
The pump of the washing structure masters jokingly called the “heart” of the machine. The main task of the pump is to pump clean water into the tank before the washing process, and then pump it back dirty, after the wash.
The time will pass, someone will have it much longer, and others less, and the time to change the pump will come, because this element wears out, because it holds a heavy load.
In our article we will tell you and explain how to check the pump, how to get to it and most importantly how to make repairs yourself.
External manifestations of the problem
Failure, in which the machine does not drain water, is considered one of the most common. This failure occurs for a variety of reasons; most of them are non-critical and quite correctable. But, whatever the reason for the failure of the work, outwardly it is manifested by the following violations:
- Drainage can function, but the process is extremely slow. In addition you may notice that a program failure has occurred.
- The program was running as usual, but the process was interrupted just when the drain should start. Drainage does not start and the program does not move.
- The washing machine works selectively, “according to the mood”: at some loads it drains properly, at other loads. it refuses.
- The drain does not start during the rinse mode, while the main wash passes without the slightest problems.
- The machine blocks the spin after emptying.
The specific location of the pump depends on the type of equipment. The exact coordinates of the pump should be specified in the diagram included in the instruction manual. If the manufacturer allows the user to replace the pump themselves, its location is surely indicated in the “Service” or “Service” section.
- Under the drum. One of the most common solutions in budget devices. To get to the pump you need to remove the panel on the bottom, previously laying the machine on its side.
- In the back of the design. To remove the pump you need to move the equipment from the wall and remove the back cover. The pump is most often located just below the centrifuge.
- Behind the faceplate. In this case it is enough to remove the bottom cover: unhook the clips or unscrew the screws.
The pump should not be positioned upwards because this would overload the drainage system. In this case, the water would have to be pushed upwards by at least a meter, which, in view of the laws of physics is impractical.
Why the washing machine pump does not work, what to do
Regardless of the brand and model of washing machine, the drainage process in each of them is the same. Any machine is equipped with a pump. a drain pump that helps pump out water while washing. The pump consists of a motor on the shaft of which there is an impeller with paddles. The drain pump is placed in the volute. The other parts necessary for normal water drainage. pipe fittings and the drain hose. are attached to the volute.
A discharge hose fitted with a filter is used to convey the water pumped from the tank to the sewerage system. It is mostly made of plastic, corrugated and equipped with molded rubber tips on both sides. It is attached to the pump volute with a cable tie with one end and to the sewage system with the other end.
The process of draining the water is also controlled by the pressostat. This sensor is designed to determine the level of water in the tank and is set to certain parameters, which do not allow to violate.
Another device that can affect the process of draining is an electronic control unit that controls the operation of all electrical parts of the washing machine.
Failure of any of these components of the water drain system can cause the washing machine to stop draining. Determine the cause and location of the failure can be determined by a detailed inspection of the machine.
Where the pump is located
To remove the pumping system from the body of the washing machine automatic (CMA), there are different ways, depending on the model of the unit. In Whirpool, Samsung, Ariston, Beko, LG, and other models, there is no bottom. Accordingly, to remove the pump, you can tilt or lay the device on its side, and disconnect the bottom panel (open the door or hatch). After that you will see the screws that fasten the snail with the filter to the front bar.
Everything is very simple in the Electrolux and Zanussi washing machines. It is enough to open the back cover of the machine, and you will see the desired assembly, which must be disassembled. The most difficult access to the required part in the AEG, Bosch and Siemens washing machines. It is possible to get to the pump only by removing the front wall of the washer.
But before removing and repairing the drain pump in the washing machine, you must first check the reasons why the water may not be pumped out:
If the inspection and cleaning has not yielded results, after a test run of the rinse and drain mode, it is required to remove the part and try to repair.
Identification of the breakage and its elimination
Once all the excess water has been drained off, you can begin to determine the cause of the washing machine failure. It is recommended to start with the water drain filter. To do this, it must be inspected for defects and clogging.
A visual inspection of the pump impeller is then made through the hole under the water drain filter. It is most often possible to determine if there is a blockage inside the pump at this stage. If no problem is detected here, the filter can be put back in.
Check the water drain hose and the siphon. This procedure requires the following manipulations:
- Disconnect the hose from the siphon;
- Next, the hose is immersed in a bucket;
- After that, you need to run the spin or drain program.
If the water managed to drain in this way, it will mean that the siphon and drain pipe are clogged. If the water still remains inside the drum, then the fault must be found internally.
If the water could not escape through the filter, then between the pipe and the pump there is probably a serious blockage. If this is the case, disassemble the machine, remove the pump and inspect all connections for foreign objects.
If disassembly of the pump could not detect any faults in it, then the cause of the inability to drain all the water from the tank of the washing machine is most likely hidden in the control module. Use a multimeter to check if the control module is energized. If there is no voltage supply to the module, it should be replaced with a functioning one. All work with the internal electronics of the washing machine is best done with the proper knowledge.
If all the troubleshooting procedures are carried out, the reason why the water in the tank is not draining can be guaranteed to be found. If you cannot repair the washing machine yourself, then the best way out of the situation is to contact a qualified master or a specialized service center.
Washing machine doesn’t drain
What to do if your washing machine Ardo, Bosch, Indesit, LG, Whirlpool, Zanussi, Samsung, Electrolux, Atlant, Beko, Bosch, Indesit, Candy, Ariston does not drain or pump, the washer does not drain all the water or does not spin and drain? Further in this article we will tell about the possible causes and ways to solve the problem. Possible symptoms of drain problems:
How to Diagnose Washing Machine Drain and Pump Problems
- The water drain does not work at all;
- the drain is slow, the washing program is not performed correctly;
- water does not drain only in certain washing modes;
- the drain does not work only after rinsing;
- There is water left in the tank after draining;
- spontaneous drainage of water;
- the washing machine buzzes and doesn’t drain the water.
If your washing machine does not empty the water, you must urgently deal with the causes of the problem: it can be a wrong choice of washing mode or clogged drain filter, or break one of the units of the washer, such as drain pump, sensors, or control board.
Many of the causes you are quite able to eliminate themselves, without wasting time and money on a master call: to clean the drain filter, check the drain hose, make sure that the drain is properly connected to the sewer. But if there was a breakdown of some internal unit of the machine or you can not determine the cause of the failure yourself, it is better to stop experimenting and call a qualified specialist with the necessary equipment and skills.
