Repair of a pump (pump) of a washing machine

washing machine pumpThe washing machine’s pump is jokingly called the “heart”. The main task of the pump is to pump out the spent 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 loads and is subject to the greatest wear. As part of the article, we will tell you how to check the pump, how to get to it, and how to carry out repairs yourself. We hope you find this information useful.

How to understand that the pump is faulty, the cause of the breakdown?

Before rushing to disassemble the washing machine with your own hands and changing the pump, you should accurately determine the cause of the breakdown. It is very possible that the reason is not at all the pump, here you need to understand as thoroughly as possible. We proceed as follows.

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

Some malfunctions can easily be localized by ear, not being a specialist, so go to the washing machine during operation and listen. Wait until the machine starts draining or filling the water according to the program. If the pump is buzzing, trying to work intensively, but the water does not enter the tank or the pump does not make any sounds - consider that the fault is localized.

After you have made sure that the pump does not work as it should, you must determine exactly whether it needs to be replaced or whether you can repair it yourself. First of all, open the drain filter and clean it from debris with our own hands.

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

If cleaning the filter does not help, check the drain hose for blockages. To do this, remove the hose and rinse it with a stream of hot water. Replace the hose and start the test wash. If the pump continues to be “naughty,” then you need to look further.

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

In the hole you will see the impeller of the pump. Put your hand in the hole and twist the impeller with your fingers, checking how it works. If the rotation of the impeller is difficult, try to find foreign objects that create interference (very often these are threads, pile, wire, etc.). If the impeller rotates freely or the cause of the difficult rotation was not 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 is no thread and pile, and the impeller still spins poorly, it means that the reason is in the mechanism and the pump must be disassembled. If the impeller spins normally, but trips once, 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 be definitely replaced.

We select tools and accessories for repair

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

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

Buy a new pump and parts for it should be careful.It is best to take the old unit, take it to a point of sale that sells similar products, and a sales assistant will help you make a choice. The same should be done with accessories. Bring the disassembled pump to the store and you will be given the right part for it.drain pump repair

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

Tools are simpler. In most cases, you can detach with a Phillips screwdriver and a penknife. However, if there is a need to check the operability of electricians (sensors, contacts, wiring), you will need to acquire a multimeter.

How to get to the pump?

To get to the faulty drain pump, it is absolutely not necessary to disassemble the entire washing machine. Repair will depend on the model of equipment and its manufacturer. It is very easy to get to the pump of washing machines of some manufacturers, while things are more complicated with others, but first things first.

  • The easiest way 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 companies on its side, remove the bottom cover (if any) and the pump will be at hand.
  • A bit more complicated is the situation with washing machines such as Electrolux and Zanussi. To get to their pump, you will need to deploy a washing machine and remove its back wall by unscrewing a few screws.
  • The most difficult 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. Read how to do this in the article. Replacing the pump in the washing machine.drain pump repair

Do it yourself

As already 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 consider all the elements. One of the most common breakdowns of a washing machine pump is the exit from a standing impeller. Very often, it simply flies off the axis, while the pump itself will turn on, make sounds, but will not pump water. We see a solution to the problem by buying a new impeller and installing it in place of the old, broken one. 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 testing and also replace if necessary. Details of the pump cost a penny, but if you neglect their replacement, or use non-original spare parts, you can waste time and eventually replace the entire pump.

Note! Carrying out repairs and dismantling the 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 or put a large rag in the vicinity.

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 of the work and other useful information that we presented thesis in our article. Good luck
