In detail: do-it-yourself drain pump repair from a real master for the site my.housecope.com.
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.
If the pump breaks during washing, it will not be possible to drain the water, so the 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 problem with a pump breakdown, contact our RemonTekhnik service center, where qualified specialists will diagnose and repair the drain pump, while you will be busy with your own business.
If the machine does not work correctly, then the following symptoms may indicate a malfunction of the pump:
The machine starts the drain program, as a result, the water does not drain, but remains in the tank;
When water is drained, a characteristic sound is heard;
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 these signs, then in most cases this is due to a pump failure. To make sure of this, you should also check the drain hose and filter. Debris can accumulate here, which makes 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 is on washing machines from Indesit, Candy, Whirpool, Ardo, Beko, Samsung, LG, Ariston, since in them you can get to the necessary 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 placed on the right, then the pump will be on top). Then unscrew the bolts (there may be bolts with a recessed head), 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 be aware of the water intake container.
In washing machines from some German manufacturers, Bosch, AEG, Siemens, the bottom has a hermetic protection, so access to the pump is opened through the front panel. Dismantling includes the following steps:
Remove the container for washing powder;
Slide the top cover (it is mounted on two self-tapping screws located on the back wall);
Remove the control module. When disconnecting the terminals, it is important to remember where which one is connected. Usually they have "fool protection" - they have a different size;
Dismantle the bottom panel (under the hatch);
Remove the front panel of the washer. Wires are connected to the hatch blocker, they must be disconnected. Do not make sudden movements, as you can damage the contacts. In the case where the panel does not fit, it is possible that the manufacturer used hidden bolts.
Remove the chips from the pump providing voltage;
Loosen the hose clamps.
Then you need to press on the pump and pull it out.
In new models of machines, in order to remove the snail 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 condition of the impeller - whether debris interferes with its free rotation. The impeller may break if a foreign body enters.
If visually the pump is in order, it is necessary to disassemble the pump motor housing. To do this, carefully push 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 loss, the impeller begins to rub against the snail, which leads to damage to both parts. All repair of the pump comes down to cleaning it, replacing seals and bearings. If the pump motor is damaged, it is better to replace it. Assembly and installation of the pump is carried out in the reverse order.
The video will help you to understand in detail the repair of the washing machine pump:
At the stage of draining, the washing machine freezes or stops working altogether? It's time to check the drain pump. In our article, you will learn how to disassemble the pump, learn how to locate it and make repairs yourself.
In most machines, only drain pumps are installed. They are responsible for draining the water after the end of the wash cycle. But in more modern models (Hansa, Bosch, Siemens) a circulation pump is used to increase pressure and supply water. Its power ranges from 25 to 35 watts.
Both types are powered by 220 volts.
Structurally, the pump consists of two parts: an engine with an impeller and a snail in the form of a plastic pipe. On one side, the snail is attached to a motor with two windings, and a drain filter is installed on the other. In older models of washing machines, the device may differ in the presence of two impellers instead of one. They pump fluid and cool the motor. At the same time, the electrician is protected by an oil seal from water ingress.
Most often, the device fails for the following reasons:
Engine bushings worn out;
The windings are closed or broken;
The impeller is broken or blocked.
But how do you know what's broken? Consider examples.
You started the wash cycle, everything went fine. But at the drain stage, the following happened:
Water does not drain from the tank;
The liquid leaves slowly, during the extraction or pumping out, the pump buzzes and makes noise;
Technique hung or turned off in the middle of the cycle;
The engine runs, but the water does not leave the tank.
Before you start repairing the suction pump, listen to its operation. If the pump buzzes when drawing water, but the tank does not fill up, disassembly and troubleshooting are required. Depending on the CM model (Lg, Samsung, Indesit), the display may show an error code. You will find its decoding in the instructions, after which you can proceed with the repair.
The circulation pump supplies water to the washing area. If you notice that the laundry is less washed or the washing solution is poorly sprayed in the drum during rotation, then inspection, cleaning or replacement of the element is necessary.
It all depends on the model of the machine. So, in the units "Samsung", "Ariston", Whirpool, LG there is no bottom, therefore, to dismantle the pumping system, it is enough to open access to the bottom. To do this, you will have to lay the car on its side or on the back wall.
Often the circulation pump is located next to the drain.
An expensive part is installed in the models of German manufacturers Bosch and Siemens. Access to it is complicated by the need to dismantle the front wall.
Through the back wall, a replacement is carried out for CM Electrolux and Zanussi.
Having decided on the location of the part, proceed to disassembly and replacement.
Disconnect the equipment from the mains electricity and water supply. Start by checking the drain filter and impeller.
Open the hatch door at the bottom of the front panel;
Unscrew the filter counterclockwise;
Substitute the container and wait for the water to drain;
Clean the filter from debris, then shine a flashlight into its mounting hole;
You will see the impeller. Scroll it if possible. If it does not rotate and is blocked, cleaning or replacement is required.
Lay the SM on the back wall. Lay a blanket on the floor so as not to damage the body;
There are three main ways to attach the drain pump: with screws and bolts, bayonet and latches.
First of all, disconnect the inlet hose and check for blockage. If after cleaning the equipment did not work normally, move on.
Remove the top cover screws. They are located at the back;
After removing the cover, unscrew the fasteners around the perimeter of the rear wall;
Start inspecting.
Pull out the powder flask by pressing the latch in the center;
Remove the top panel;
Disconnect the control panel fasteners. Disconnect contacts and put aside;
Bend the hatch cuff inside the tank, remove the clamp;
Unscrew the two bolts of the lock-lock;
Disconnect the lock contacts;
Unscrew the fixing bolts of the front panel;
Remove from place;
To replace, choose a part that exactly matches the characteristics of the previous one. It is best to remove the broken element and go to the store with it.
Disconnect the pump contacts;
Loosen the clamps, unscrew the bolts. If the part is mounted on latches, press them with one hand and pry with a screwdriver with the other.
After the pump is in your hands, inspect the mechanism. Clean holes and impeller. Disassembly required?
Remove the pump snail (pump cover);
To do this, turn it counterclockwise, or unscrew the bolts;
How to remove the impeller? It must be dismantled to clean the internal parts;
Pry off the housing latches and remove it;
If the cross is not removed, warm up its shank with a hairdryer, then pry it with a screwdriver;
After pulling out the magnet with the impeller, clean it of dirt;
Remove the magnet from the shaft. Behind it you will see a bearing;
Use pump lubricant to restore bearing performance;
If the element is beyond repair, install a new bearing;
