Drain pump for a washing machine, do it yourself repairs

In detail: a drain pump for a washing machine does it yourself repair from a real master for the site my.housecope.com.

Modern models of washing machines consist of high-tech units and elements.

It is impossible to say which is more important, which detail means more.

But without a pump - the heart of a washing machine - you cannot wash, rinse, or wring out the laundry.

Supply water to the tank, drain the used liquid - these are the tasks of the pump.

Constant loads, power outages, poor quality water affect the operation and life of the pump.

Disassembly of the machine and subsequent replacement of the pump are carried out in cases of accurate diagnosis of a breakdown.

It is necessary to make sure that the cause of the malfunction is in the pump (the principle of operation of the diaphragm pump).

You need to do the following:

  1. listen to the sound of the pump at work;
  2. check the drain filter for debris or sediment;
  3. check the patency of the drain hose;
  4. inspect the pump impeller for jamming;
  5. test the operation of sensors and contacts going to the pump (check the membrane filter for water).

The nature of some faults is determined by ear.

To do this, you need to carefully listen to the sound of the pump during operation. What to do if the washing machine hums when the water is drained is written here.

Strong buzzing, an attempt to drain the water, in which nothing happens or the absence of sounds speaks of the approximate localization of the breakdown.

After that, we proceed to the exact determination of the faulty element. Replacement or repair should be determined.

What do you know about a non-volatile septic tank for a country house? What is more profitable, buy ready-made or build it yourself, read in a useful article.

How and when to use the hand held copper pipe cutter is described on this page.

Possibly the malfunction was caused by a small coin or bra bone that got into the drain filter.

Opening the filter and remove debris and dirt. Cleaning may not help (it is written about shutoff valves for high pressure pipelines here). In this case, we check the drain hose. The dismantled hose is rinsed with hot water.

Putting the drain hose (how to properly connect to the washing machine, find out here) in place, we start the test wash. Continuing "whims" indicate the need for further troubleshooting.

The next step is to check the impeller.... We unscrew the drain filter. This will help to gain access to the pump without disassembling the washer case.

By shining a flashlight into the drain hole, you can see the impeller. The blades should rotate freely with little effort.

If movement is difficult, try to feel for a foreign object stuck between the blades.

This can be hair, thread, a piece of wire, or pile. If there are no foreign objects or the impeller rotates freely, you will have to disassemble the machine.

Having received direct access to the pump, we remove the pump and conduct a thorough inspection.

Lack of foreign objects with poor rotation of the blades, it indicates a malfunction of the mechanism.

In this case, the pump will have to be disassembled.

Uneven operation is possible in cases of a burnt contact, a faulty sensor or a control unit (how to remove scale in the washing machine, read here).

In the event of such breakdowns, the impeller moves normally. If the check of the contact groups, sensors and control yielded nothing, then the pump (which is needed for the pond in the country, is written here) must be replaced.

Which tool to take depends on the problem. Consider the case of a malfunction of the pump itself.

The following items will be required for repairs:

  • drain pump;
  • impeller with axle;
  • cuff with gasket;
  • pulley;
  • sensors and contacts.

Buying a pump and accessories will require accuracy.... The best option would be to consult a specialized store.

A dismantled pump with a malfunction will help to make the right choice. According to this model, the consultant will select a similar option and suitable components.

ATTENTION!
Purchases on the Internet are carried out according to the numbers found on the parts.

A complete match of the number guarantees the purchase of the correct model.

The tool is easier to find... A Phillips screwdriver and a pocket knife are commonly used.

Additionally, it is worth preparing a multimeter that will help check the electrical part:

The pump can be dismantled and repaired without disassembling the washing machine.

Options vary by model and the manufacturer.

In some devices, access to the pump is easy, with other models you have to tinker.

As for brands, the easiest way to get to the pump for washing machines is from:

Lay the washer on its side, remove the lower part of the case. The pump is available for inspection, repair or replacement.

To do this, you need to unscrew several self-tapping screws (about collet fittings for metal-plastic pipes is written in this article).

The most difficult option is for models that have to remove the front part of the case with the control unit.

Such devices include models of firms:

The simplicity of the design will allow you to carry out repairs on your own. In the absence of visible damage, you will have to disassemble the device and check each element.

Common malfunction - impeller breakage. If the blades flew off the axis, then the pump will remain operational, but will stop pumping fluid.

In this case, a new impeller is purchased and installed instead of the failed one.

Disassembling the pump will allow you to check the gaskets. Any sign of damage is a reason for replacement.

The second step is to inspect the moving structural elements.

If wear marks are visible on the pulley or other parts, replace these parts with new ones.

Pump accessories are not expensive, but can lead to serious problems.

Therefore, you should purchase original spare parts (read about the electric screw die for threading in this article).

IMPORTANT!
Removing the pump can drain stagnant water.
Before disassembling, prepare a container or rags to help drain the water from the pump.

Change or repair the pump washing machine yourself.

  • know the sequence of actions,
  • possible causes of malfunctions,
  • design and principle of operation of the pump.

It is quite possible to do it yourself repair the drain pump of your washing machine without calling the master. But first, you need to carry out the simplest diagnostics of the device.

If the machine does not work properly, before disassembling the drain system, you need to make sure that the malfunction is located exactly in this place. It can be determined by several criteria:

  • the water drain program has started, but the pumping system does not work;
  • during the drain, strong noises and buzz are heard;
  • water is pumped out, but flows out very slowly;
  • during the operation of the system, the machine may turn off;
  • the pump motor hums but no water flows out.

If one of these breakdowns is found, it can be said with a high degree of probability that the washing machine pump will have to be repaired.

There are different ways to remove the pumping system from the body of an automatic washing machine (CMA), depending on the model of the unit. In models Whirpool, Samsung, Ariston, Beko, LG, and others, no bottom... Accordingly, you can remove the pump by tilting or laying the device on its side, and disconnecting the bottom panel (open the door or hatch). After that, you will see the screws that secure the snail with the filter to the front plate.

Everything is very simple in Electrolux and Zanussi CMAs. It is enough to open back cover machines, and you will see the desired unit, which must be disassembled. The most difficult access to the required part in the AEG AEG, Bosch and Siemens. You can get to the pump only by removing front wall washing machines.

But before removing and repairing the drain pump in the washing machine, you must first check the reasons due to which the water may not be pumped out:

  • severe blockage drain hose (it is necessary to remove it and clean it well);
  • drain filter clogged with debris (remove the filter from the snail and rinse well with water).

If the check and cleaning did not give results, after a test run of the rinse and drain mode, you need to remove the part and try to repair it.

To disassemble your pump for troubleshooting, first disconnect it from the snails... To do this, you need to unscrew the screws.

Some pump models have a different attachment to the volute. It is enough to turn it counterclockwise and it will detach.

In the next step of troubleshooting, check impeller. Although it can be seen without disassembling the entire structure: just pull out the drain filter. It is possible to visually determine whether it is broken or not. But to find out whether it scrolls on the shaft or is fixed will not work without complete disassembly.

The picture below shows a broken impeller due to a coin falling into the system.

The impeller should not turn easily. Normally, it turns with some delays (jumps), due to the magnet rotating in the coil.

If rotation is difficult, and no visible interference in the form of various debris is observed, then you will have to disassemble the pump completely.

To do this, using a screwdriver, pry the latch on the motor housing on both sides, and remove it from the coil.

There are also so-called “non-separable” motors, but they are also amenable to “treatment”.

After detaching the body with blades from the coil, we will see a monolithic part. It seems that the crosspiece cannot be removed. But there is a little trick.

  1. Take the usual construction hair dryer, set it to the lowest temperature, put on gloves, and begin to warm up the shank of the part (its long part). Do this carefully.
  2. After a while, when the shank warms up well, pry crosspiece screwdriver and carefully remove it (together with the magnet) from the housing.

There may be a lot of dirt on the magnet and in the place from which it was removed. Everything must be thoroughly cleaned, after which you can remove the magnet itself from the shaft. You will see bearing, requiring, respectively, cleaning and lubrication. Also lubricate the bearing on the bottom of the housing.

Then insert everything into place, with slight pressure until it clicks. Sealing ringunder the blades should fit snugly into place.

The picture below shows a dirty motor from an Indesit typewriter.

In motors of this type, in addition to the above procedures, it may be necessary to replace the oil seals.

Contamination is not the only reason for the device to malfunction. If the bearings fail, beating occurs during the rotation of the shaft. Due to the beating, the impeller begins to rub against the casing of the snail. This causes noise and unproductive operation of the pump, even to a complete stop.

This problem is solved by replacing ball bearings, which can be purchased at specialized retail outlets or at a service center for servicing household appliances.

If at the moment it is not possible to buy a new part, and the wash cannot wait, then you can temporarily extend the life of the pump by shortening blades 2 millimeters with a sharp knife. But don't overdo it: if you cut more, system performance will drop.

After cleaning, replacing bearings or oil seals, the repair of the motor can be considered complete. Install the housing with blades into the spool and secure with latches. Subject to safety rules, connect a voltage of 220 V to two contacts, and check the work devices. After making sure of the normal operation of the device, you can connect the volute and return the entire structure to the SMA housing.

As you could see, repairing a washing machine pump with your own hands is not such an impossible task and everyone who has carefully read these recommendations can do it.
