Do-it-yourself lg washing machine drain pump repair

In detail: do-it-yourself lg washing machine drain pump repair from a real master for 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, then it is more advisable to replace it. Assembly and installation of the pump is carried out in the reverse order.

The video will help you understand in detail the repair of the washing machine pump:

The masters jokingly call the pump of the washing machine the “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. As part of the article, we will tell you how to check the pump, how to get to it, and how to repair it yourself. We hope this information will be useful to you.

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 figure it out as thoroughly as possible. Let's 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 pump impeller, possibly jamming.
Check the sensors and contacts going to the pump.

Some malfunctions can be localized by ear without being a specialist, so go to the washing machine during operation and listen. Wait for the moment when the machine starts to drain or fill water, acting according to the program. If the pump is buzzing, trying to work intensively, but no water enters the tank or the pump does not make sounds at all - consider that the malfunction is localized.

After you are convinced that the pump is not working as it should, you should 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 your own hands.

It is possible that the pump impeller is jammed due to a coin or a 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 hot water. Replace the hose and run a test wash. If the pump continues to "act up", 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 without even disassembling the machine, through the drain filter, which must be unscrewed. To make it more convenient, get a flashlight and shine it into the hole from which you unscrewed the cork.

In the hole you can see the pump impeller. Put your hand through the hole and rotate the impeller with your fingers, checking how it works. If the rotation of the impeller is difficult, try to feel for foreign objects that interfere (very often these are threads, pile, wire, etc.). If the impeller rotates freely or the cause of 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 carefully. 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 spins normally, but works every other time, then the problem is in burnt contacts, a sensor or a 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 components will depend purely on the nature of the problem, so we will describe the option, as they say, to the maximum, if everything is bad with the pump. In this case, the repair of the washing machine may require the following components:

drain pump assembly;
impeller;
axis;
cuff;
pad;
pulley;
drain pump sensor;
contacts.

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

Important! If you decide to order components in an online store, then you should look 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 penknife. However, if it becomes necessary to check the performance of electricians (sensors, contacts, wiring), you will need to get a multimeter.

To get to a faulty drain pump, it is not at all 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, with others it is more difficult, 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.
The situation is a little more complicated with washing machines such as Electrolux and Zanussi. To get to their pump, you will need to deploy the washing machine and remove its back wall by unscrewing a few 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 along with the control panel. For information on how best to do this, read the article Replacing the pump in the washing machine.

As mentioned above, the washing machine pump 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 the washing machine pump is the failure of the 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 the solution to the problem in buying a new impeller and installing it in place of the old, broken one.

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 wear and replace if necessary. Pump parts cost a penny, but if you neglect to replace them, or use non-original spare parts, you can waste time and end up replacing the entire pump.

Note! When repairing and dismantling an old pump, keep in mind that it can have quite a lot of stagnant water, so be sure to put a container or a large rag nearby.

As a result, we note that it is quite possible to repair a 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, which we have summarized in our article. Good luck!

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 washed worse 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;

Assemble the body in reverse order.

Here's how the disassembly goes:

Mechanical check completed. Let's get to the electronics.

Take a multimeter tester;
Turn it into voltage measurement mode;
Attach the probes to the contacts of the part;

Look at the screen. Is 0 or 1 on? The motor burned out and needs to be replaced;
If a three-digit number is displayed, then the problem may not be in the engine, but in the electronic board. A more accurate diagnosis will be carried out by the master.

Let's consider how to replace the circulation pump using the example of a Veko automatic washing machine.

Open access to the bottom of the SM;
The circulation device is located next to the drain. Turn off the wiring and attach the multimeter probes to its contacts;

In the normal state, the resistance will be about 180 ohms. In case of discrepancy, unscrew the fastening screws, install a new part.

How to prevent breakage? Keep things out of the drum, check pockets before loading clothes, select the correct wash cycles, and clean filters frequently. Image - Do-it-yourself lg washing machine drain pump repair

The washing machine collects and drains water thanks to the most important element - the pump. With prolonged use, it can fail (physical wear), which is quite common, which is why the pump is considered the weak point of modern washing machines.

If there is a problem with the pump, machine can:

do not respond to the installed program;
make buzzing sounds when collecting or draining water;
pour water into the drum in a smaller amount than it should be;
in the process of water collection, a complete shutdown of equipment is possible.

In order to diagnose and carry out, if necessary, repair or replacement of the pump of the machine, you need:

hear how the machine works to detect extraneous sounds. If the machine makes a lot of noise when draining, then there is water in the pump or some of its parts are deformed;
open socket for removing blockage in the drain filter. All small and foreign objects are here - hair, threads, buttons, seeds, etc.;
clean drain hose. Even if it is not damaged in appearance, you still need to remove it and rinse it under the pressure of hot water;
check the operation of the impeller, perhaps it is jammed. It is located behind the drain filter, which must be unscrewed and pulled out. The impeller blades that need to be rotated will be visible. The rotation should not be too light. If there is any debris - knuckles from bras, coins, threads and hair, it must be removed;
check the integrity of the contacts and the operability of the sensors going to the pump.

If during the diagnostic process the pump was determined to be the cause of the malfunction in the washing machine, then you will have to inspect it.To get to it, you need standard tools.

The pump broke down due to a malfunction of the engine, as a result of which there is no voltage to the pump.
The seal (rubber or plastic) is damaged by scale and dirt that settles on the impeller.
Incorrect connection of the pump or failure of the water level sensor cause the pump to work continuously.
The pump will not be able to drain the water because the filter is clogged.
Small foreign objects destroy the impeller. It's easy to diagnose. When starting the pump, the machine makes a whooping sound.

Models of washing machines Candy, LG, Whirpool, Ariston, Beko, Samsung are equipped with a pump located at the bottom. To get to it, the washing machine is laid on its side and the bottom panel is removed. The snail with the filter is attached with screws that are unscrewed and the desired part is in your hands.

If we talk about the Zanussi, Electrolux models, then the pump is located behind the back cover, which will need to be removed.

The most difficult models in terms of disassembly are Bosch, AEG, Siemens. They will have to dismantle the entire front panel.

Under heavy loads, the pump is protected by fuses that are located on the winding of the part and turn off. When the temperature normalizes, the contacts are restored.

To get started you need disconnect the pump from the snail. In general, there are two types of fastening: simple screws and screwless (you only need to turn the pump counterclockwise). At this stage, you can find out if the impeller is scrolling on the shaft. Normally, it should spin with small delays, the so-called jumps. This is due to the action of the magnet rotating in the coil. If it turns hard and there is no debris, then you will have to completely disassemble the part and see if it is possible to repair the pump impeller of the washing machine.

There is a latch on the motor housing. on both sides, which must be unhooked with a screwdriver. This is if your typewriter has a collapsible motor, but there are non-collapsible types. At first glance, it is impossible to make out, but if you know some of the nuances, then you can.

A building hair dryer will help, which needs to warm up the long part of the part, the so-called shank little temperature. After heating the shank, the cross with the magnet is removed from the body. Usually dirt accumulates on the magnet and in the place where it was pulled out. After cleaning, the magnet itself is removed. Next, the bearing will be visible, which is also cleaned and lubricated. After these procedures, the part is assembled back. Under the blades is a ring that should fit snugly into place. The seal may need to be replaced.

Because of this, friction appears between the snail and the impeller, which causes malfunctions and repairs of washing equipment pumps. The problem can be solved by replacing the bearings. In an emergency, when it is not possible to buy a new part, and washing cannot wait, only shortening the blade by no more than 2 mm will save. This is done with a sharp knife.After repair, the body is installed in the coil and fixed. This ends the troubleshooting of the pump on its own.If you follow these recommendations, you can significantly extend the life of the drain pump.

Always remove foreign objects from pockets before washing.

Use laundry bags.

In case of strong, coarse dirt, clean things, and also manually get rid of animal hair before immersing in the machine.

Install filters on the inlet pipe.

Take prophylaxis against scale.

When washing things with buckles, studs, turn things inside out.

From the material described above, you already know how you can check the water pump of your washing machine.After that, you can begin to eliminate problems, and quite often you can do it yourself.

First, pay attention to the most common malfunctions:

blockage or damage to the drain hose;
the drain filter is clogged;
jammed impellers due to trapped debris or solid objects.

Important! Most of the blockages that cause AGR failures can only be prevented or removed during the debris buildup stage. To help you, we have prepared an article in which you will read about all the nuances of cleaning the washing machine with Domestos.

Over time, threads, hair, and other debris accumulate in it, which should be eliminated. Sometimes this happens more often, sometimes less often, but this problem is quite common in washing machines.

Even if visually it is in perfect order, it still does not hurt to rinse it. To do this, remove and run a stream of hot water through it.

When you do this, we recommend that you test the washing machine. To do this, simply run a test wash to check how well the pump drains and pumps water. For this action, the most ordinary rinse mode or some other is suitable. If there are no extraneous sounds, and water gets inside normally, then everything is fixed. But if the pump continues to give certain failures, then turn off everything and continue to make repairs.

The good news is that you can get to it even without a serious analysis of the equipment. It will be enough just to unscrew the drain filter, under which the rotation blades are located.

The following actions are currently being performed:

When you get to the drain filter, check it.
Unscrew the filter, then carefully remove it from the hole.
Enlighten the hole with a flashlight in order to better examine it.
Try spinning the blades with your hands.
Eliminate all debris, if any.

Important! As a rule, the impeller on the pump should not rotate too easily, but also without obvious difficulties. If this does not happen, then foreign objects must have got inside. It happens that coins, knuckles from bras, plaques, and other similar items get into it from clothes. In addition, hair or ordinary threads can make rotation difficult. Usually all this can be fixed without any special difficulties with your own hands, so you do not have to deal with major repairs, as well as disassemble the washing machine.

In order for your washing machine to serve you as long as possible without breakdowns, be sure to familiarize yourself with how the care of the automatic washing machine should be carried out.
