The pump in the washing machine is designed to pump water into the drum, and drain the waste water through the drain hose into the sewer. Malfunctions in the operation of the pump are signaled by the control panel, on the display of which the corresponding error code appears. Under this breakdown, different manufacturers encrypt their code, so the same code in machines from different manufacturers may indicate breakdowns of a different nature.

A breakdown of the pump during washing will make it impossible to drain water, thus, water will remain in the tank, and the hatch will not be able to open, since the control module will signal the continuation of washing or rinsing. Manufacturers use pumps of different design features and power, depending on the volume of water consumed.

If you are faced with a pump breakdown problem, contact our service center "RemonTechnik", where qualified specialists will diagnose and repair the drain pump, and you will be busy with your business.

If the machine does not start working correctly, then the following symptoms may indicate a pump malfunction:

  • The machine starts the drain program, as a result, the water is not drained, but remains in the tank;
  • When draining water, a characteristic sound is heard;
  • The water is pumped out slowly, not completely;
  • The machine turns off until the water is completely drained;
  • The control module freezes;
  • The pump motor hums, but the water does not drain.

If you notice one or more of the listed symptoms, then in most cases this is due to a pump breakdown. To make sure of this, you should also check the drain hose and filter. Debris can accumulate here, making it difficult for the water to flow.

The location of the pump may vary from brand to brand. The easiest way to dismantle the pump on "washing machines" from Indesit, Candy, Whirpool, Ardo, Beko, Samsung, LG, Ariston, since they can get to the required unit through the bottom. To open access to the pump, it is enough to put the household appliance on its side (so that the door is on the right, then the pump will be on top). Then unscrew the bolts (may be recessed head bolts), and remove the power terminals. Then disconnect the drain hoses, which are attached with clamps. Often manufacturers use disposable clamps, you should take care of spare ones for installing the pump.

Important! If the pump breaks down, water may remain in the drum, nozzles and filter, so you should remember about the container for water intake.

In washing machines from some German manufacturers, Bosch, AEG, Siemens, the bottom is sealed, so the pump can be accessed through the front panel. Dismantling includes the following steps:

  • Remove the container for washing powder;
  • Slide the top cover (it is fastened with two self-tapping screws located on the back wall);
  • Dismantle the control module. When disconnecting the terminals, it is important to remember where which one is connected to. Usually they have "foolproof" - they have different sizes;
  • Dismantle the bottom panel (under the hatch);
  • Remove the front panel of the "washing machine". Wires are connected to the sunroof blocker, they must be disconnected. Do not make sudden movements, as the contacts can be damaged. In the event that the panel does not lend itself, it is possible that the manufacturer used hidden bolts.
  • Remove the chips from the pump that provide voltage;
  • Release hose clamps.

Then you need to push on the pump and pull it out.

In new models of machines, in order to remove the volute from the pump, it is enough to turn it counterclockwise; otherwise, you will have to unscrew the bolts. Then you should disconnect the filter, and check the impeller's serviceability - whether debris interferes with its free rotation. The impeller may break if foreign matter enters.

If the pump is visually in order, it is necessary to disassemble the pump motor housing. To do this, you need to carefully push apart the plastic latches and remove the motor from the coil. You can also check the presence and integrity of the bearings.

As a result of their falling out, the impeller begins to rub against the volute, which leads to damage to both parts. All pump repairs are reduced to cleaning it, replacing oil seals and bearings. If the pump engine is damaged, then it is more expedient to replace it. Assembly and installation of the pump is carried out in the reverse order.

The masters jokingly call the pump of the washing machine "heart". The main task of the pump is to pump water into the washing tank, and then pump out the waste liquid from the tank. Sooner or later, the time comes to repair the pump or replace it with a new one, because, along with the engine, this unit experiences the greatest stress and is subject to the greatest wear and tear. As part of the article, we will tell you how to check the pump, how to get to it, and how to make repairs with your own hands. We hope you find this information useful.

Before you rush to disassemble the washing machine with your own hands and change the pump, you should accurately determine the cause of the breakdown. It is very possible that the reason is not at all in the pump; here you need to understand as thoroughly as possible. Let's proceed as follows.

  • First you need to listen to the pump.
  • Open the drain filter and clean if necessary.
  • Check and clean the drain hose.
  • Check the rotation of the pump impeller; there may be a jam.
  • Check the sensors and contacts going to the pump.

Some malfunctions can well be localized by ear, without being an expert, so go to the washing machine while you work and listen. Wait for the moment when the machine starts to drain or fill water, following the program. If the pump hums, tries to work intensively, but water does not flow into the tank or the pump does not make any sounds at all - consider that the malfunction is localized.

After you have made sure that the pump is not working as it should, you should determine exactly whether it needs to be replaced or whether you can make repairs on your own. First of all, we open the drain filter and clean it from debris with our own hands.

It is possible that the pump impeller is jammed due to a coin or bra bone caught in the filter, so it does not work as it should.

If cleaning the filter did not help, check the drain hose for blockages. To do this, the hose must be dismantled and rinsed with a jet of hot water. Replace the hose and run a test wash. If the pump continues to be "capricious", then you need to look further.

Next, you need to check the rotation of the impeller of the drain pump of the washing machine. The impeller can be reached even without disassembling the machine, through the drain filter, which must be unscrewed. To make it more convenient, get a flashlight and shine into the hole from which you unscrewed the plug.

In the hole you will see the pump impeller. Put your hand through the hole and turn the impeller with your fingers, checking how it works. If the rotation of the impeller is difficult, try to feel for foreign objects that are interfering (very often these are threads, pile, wire, etc.). If the impeller rotates freely or the reason for the difficult rotation has not been found, you will have to disassemble the washing machine with your own hands.

Having reached the pump, we check the impeller. If necessary, the drain pump can be dismantled and inspected more thoroughly. If there are no threads and lint, and the impeller still does not spin well, then the reason is in the mechanism and the pump must be disassembled. If the impeller rotates normally, but it works every other time, then the problem is in the burnt contacts, sensor or control unit.

If everything is checked, but the pump still does not work, then it must definitely be replaced.

The composition of the necessary tools and accessories will depend solely on the nature of the problem, so we will describe the option, as they say, to the maximum, if everything is completely bad with the pump. In this case, the repair of the washing machine may require the following components:

  1. drain pump assembly;
  2. impeller;
  3. axis;
  4. cuff;
  5. pad;
  6. pulley;
  7. drain pump sensor;
  8. contacts.

Purchase a new pump and parts for it with caution. It is best to take an old unit, take it to a retail outlet that sells similar products, and a sales assistant will help you make a choice. The same should be done with accessories. Bring the pump disassembled to the store and you will be given the right part for it.Image - DIY washing machine drain pump repair

Important! If you decide to order components in the online store, then you should search for them by the numbers that you need to read on the old pump you removed.

With tools, things are easier. In most cases, it can be removed with a Phillips screwdriver and a pocket knife. However, if there is a need to check the performance of an electrician (sensors, contacts, wiring), you will need to get a multimeter.

It is not necessary to disassemble the entire washing machine to get to a faulty drain pump. The repair will depend on the model of the vehicle and its manufacturer. It is very easy to get to the pump of washing machines of some manufacturers, with others the situation is more complicated, but first things first.

  • The easiest way is to get to the pump of washing machines: Samsung, Candy, Ariston, Ardo, Beko, Whirpool, LG, Indesit. To do this, turn the washing machine of one of these firms on its side, remove the bottom cover (if any) and the pump will be at hand.
  • The situation is a little more complicated with washing machines such as Electrolux and Zanussi. To get to their pump, you will need to unfold the washing machine and remove its back wall by unscrewing several screws.
  • The most difficult thing is to get to the pumps of washing machines from manufacturers such as AEG, Bosch, Siemens. In this case, you will have to dismantle the front wall together with the control panel. For information on how best to do this, read the article Replacing the pump in the washing machine.Image - DIY washing machine drain pump repair

As mentioned above, the pump of the washing machine is quite simple in design and it is not difficult to repair it. If there is no visible damage on it, then you need to disassemble it and carefully examine all the elements. One of the most common breakdowns of a washing machine pump is a standing impeller exit. Very often it just flies off the axis, while the pump itself will turn on, make sounds, but will not pump water. We see the solution to the problem in buying a new impeller and installing it in place of the old, broken one. Image - DIY washing machine drain pump repair

When disassembling the pump, carefully inspect all rubber gaskets. If even the slightest traces of mining are visible on them, the gaskets must be replaced. Also inspect all moving parts of the pump, including the pulley, for working and also replace if necessary. Pump parts cost a penny, but if you neglect their replacement, or use non-original spare parts, you can waste time and ultimately replace the entire pump.

Note! When carrying out repairs and dismantling an old pump, keep in mind that there can be quite a lot of stagnant water in it, so do not forget to put a container nearby or put a large rag.

As a result, we note that it is quite possible to repair the washing machine, or rather its pump, with your own hands, without resorting to the help of a specialist.To do this, you need to study the rules for the production of work and other useful information that we have presented thesis in our article. Good luck!
