Do-it-yourself lq washing machine repair

In detail: do-it-yourself repair of the lq washing machine from a real master for the site my.housecope.com.

LG direct drive washing machines are in high demand among customers. The new design made it possible to significantly increase the engine resource, while the SM belongs to the affordable price segment.

But even such equipment is subject to breakdowns, and maintenance of LG washing machines in a service center is sometimes expensive. Therefore, we will tell you about the typical malfunctions of this brand and the possibilities of self-repair.

According to statistics, breakdowns of direct drive LJ washing machines occur after five years of operation. To understand where to start troubleshooting, let's look at how a direct-drive CM and a standard machine work.

Look at the diagram of the LG washing machine:

In the first case, the drum is rotated using a drive belt. In the second, the drum rotates the motor directly. Such a motor also does not have brushes that constantly wear out. In the event of a breakdown, you will immediately determine that the reason is in the motor, and not in the parts adjacent to it.

We have disassembled the principle of operation, now we will consider which nodes most often fail:

How can a user know where exactly the LG washing machine has broken down? For this, there is a self-diagnosis system. If a problem is detected, the system displays the EJ error codes on the display.

You just have to decipher the code and find the problem.

The Korean company LG makes great direct drive washing machines. This technology really significantly increases the service life of the engine and moving elements. However, these machines are also characterized by specific malfunctions, noted by the specialists of the service centers as the most common. If you are the owner of an LG washing machine, then in 80% of cases you will have to deal with the malfunctions discussed in this article.

Experts from the world's leading service centers note the relatively high reliability of LG washing machines. The most "tenacious" unit of this machine is considered to be the engine, which breaks down only in one case out of 500 calls to service centers, and then in half of the cases, the cause of the module malfunction is a factory defect. Moving elements are also considered to be quite reliable, except for bearings, they are repaired more often.

What units of the LG washing machine break down most often? Let's list them:

a heating element;
pressure switch;
bearings;
wires and terminals;
drain pump;
filling valve.

Malfunctions of these most important units of the washing machine manifest themselves in different ways. It is necessary to carefully analyze the "symptoms" in order to more or less accurately diagnose the problem of the module even before disassembling the "home assistant". In particular.

Note! When diagnosing faults in the washing machine with your own hands, be sure to listen and take a closer look at its work at the stages of washing, rinsing, spinning and draining. In addition, read the user manual, any deviations from the norm should alert you.

To get to the heating element of the washing machine, you need to unscrew several fasteners that hold the back wall of the LG washing machine by yourself, and then dismantle this wall. Next, you need to pay attention to the lower part of the tank (near the very bottom). Two paired contacts with a screw in the middle should stick out from there, to which several wires go - this is the ten. We check the contacts with a multimeter, if its display shows a value less than 20 Ohm - the ten is faulty.

Removing the ten is easy. We unscrew the screw we mentioned with our own hands, pry on the sealing gum with a screwdriver and pull out the heating element from the bowels of the tank. We visually check the status of the module. Burnt teng rarely does not have any visually noticeable damage (usually these are burnt spots). In most cases, the heating element breaks down due to a layer of scale that settles on it. Also, a breakdown can be provoked by a voltage drop or water that gets on the contacts. The video guide will help you to correctly remove the ten.

Repair of this module of the LG washing machine is not possible, only replacement. It is necessary to purchase an original spare part from the manufacturer and install it in the tank of the washing machine, not forgetting to install the sealing rubber. In the process of installing the heating element, you need to be most careful about the sealing rubber of the heating element. To make it sit better in place, you need to lubricate it with a small amount of machine oil.

Important! If the sealing gum of the heating element sits loosely in the bore hole, water from the tank will seep onto the contacts of the heating element and it will most likely burn out again in the near future. Be careful.

Washing machine electrical repair LG boils down to checking all the wires and terminals coming from the control module to all of its units. It's not just about checking all the wiring with a multimeter - it goes without saying. It is also necessary to carry out a visual check: torn clamps, fragments of wires without insulation, traces of burning and melting of contacts. All wiring problems that can be detected during the check must be resolved by replacing damaged conductors and terminals - this is the repair of the electrician.

It is not difficult to diagnose faults in the filler valve of an LG washing machine on your own, and it will not be difficult to repair this module with your own hands, if you act methodically, according to a pre-planned plan. Dismantling and replacing the filler valve with your own hands is carried out in the following order.

Unroll the washing machine.
The inlet hose, which is connected to the water supply at one end, is screwed to the inlet valve with the other end. We turn off the cold water supply by turning off the tap.
We unscrew the inlet hose.
We take out, check and clean the filter of the inlet valve, it may be clogged with dirt and the water does not pass.
If everything is in order with the filter, remove the top cover of the washing machine, unscrew the two screws holding the valve, disconnect it from the pipes.
Next, we need to check the rubber bands of the valve, in 90% of cases the problem is their wear and the inability to retain water in the future. If so, change the rubber bands.
If it's not about the rubber bands, then most likely the problem is in the control electrics of the valve. In this case, the entire valve must be replaced.

To the drain pump of the washing machine LG can be reached without even disassembling it. You just need to tilt the machine on its side, after that it will be possible to get close to the unit through the bottom. We check the drain pump sensor with a multimeter, if everything is in order, then the problem is in the unit itself. Next, we proceed in order.

Unscrew the lower part of the front panel of the machine.
We unscrew the fasteners securing the drain pump.
We substitute the basin, since water will flow from the unit during removal.
Disconnect the plugs and remove the wires with the sensor.
Disconnect the pipes, drain the water and remove the unit to the side.

Note! Before placing the clipper on its side, remove the powder cuvette as directed by the user manual, as water remaining in the cuvette may spill onto the control box and damage the electronics.

Once the drain pump has been removed, it is best to have it checked and repaired by a specialist.Only he can finally say whether the pump has really come to an end, if so, then you need to buy and install a new one. Assembly is carried out upside-down. The easiest way is to change the pressure switch (water level sensor) of the washing machine. If you manage to disassemble it correctly, then it will not be difficult to replace it yourself.

Bearing failures are a matter of time or a factory defect. The user can influence this process only by the intensity of the use of the home assistant. Bearing malfunctions must be repaired immediately, because if this is not done, the loose pulley can damage the tank and then repairs will be very expensive. In this case, the user manual will not help; you either need to contact a specialist or study specialized information.

Thanks to direct drive technology, which is implemented on most models of washing machines from the company LG, bearings, motor, pulley and other parts wear out much more slowly and last longer. Nevertheless, there are still cases of bearing failure, and this poses a problem for “self-repair lovers”. Not everyone knows how to properly remove the bearing from the drum, but to start doing this, you need to remove and disassemble the washing machine tank.

Bearing repairs must be done very carefully, using a special hammer with a bronze bump and a thin metal rod. It is necessary to pull out the bearing by striking its opposite edges. First, we place the rod on one edge of the bearing and strike it lightly with a hammer, then transfer the rod to the other edge and again strike it lightly. The procedure must be repeated until the old bearing pops out, then a new bearing can be put in its place.

In conclusion, we note that malfunctions of any module of the LG washing machine, you can try to fix it. Of course, even if you study the relevant technical information and expert advice, successful repairs are not guaranteed, but it is definitely worth trying, especially since in most cases you have to deal with typical breakdowns. If something doesn't work, you can read the washing machine repair manual.

To repair a LG washing machine with your own hands, you need to know well the design features of the washing machine and its main faults that occur most often.From time to time, many have a situation when the washing machine stops working normally. Modern units, including LG, have no problems with diagnostics and error detection. The fact is that the screen-display shows codes, each of which corresponds to a particular malfunction. LG washing machines have their own coding, deciphered in the attached technical documentation. It also provides practical advice on how to eliminate the resulting breakdowns.Explanation of the main fault codes for LG washing machines:Many problems that arise with LG washing machines can be solved independently, in accordance with the decoding of the codes displayed on the display. If the measures taken have not led to a positive result, it is recommended to perform a service test for a more complete diagnosis. Thanks to the information received, the repair of the washing machine can be done independently. Sometimes there are breakdowns that are not provided for by error codes. They also need to be able to identify and eliminate.Sometimes the washing machine does not react in any way when the plug is plugged into the socket: the indicator lights do not light up, the musical greeting does not turn on. The reasons for this condition can be very different. Some can be easily removed on their own, while others - only in a service center.Why the washing machine does not turn on:

Lack of electricity is the most common cause.For various reasons, an automatic machine or an RCD is triggered. Possible outlet malfunction.

Defective mains wire. The serviceability of the washing machine's power cord is checked using a multimeter. If a problem is found, the cord is completely replaced or repaired. All connections must be made only by soldering.

Malfunction of the power button, which receives power after connecting to the network. To check its performance, a tester is also used, set to the buzzer mode. The machine must be de-energized, and the button itself rings in both positions - on and off. If it is in working order, the multimeter will confirm this with a characteristic sound. If a malfunction is found, the button must be replaced.

Sometimes the LG washing machine will not turn on due to a malfunctioning noise filter (FPS). This device is designed to damp the electromagnetic waves emitted by the washing machine that interfere with the operation of other devices. When the FPS fails, it no longer passes electric current through the circuit, as a result, the washing machine does not turn on. Serviceability checks are carried out using a multimeter. It is necessary to ring the entrance and exit in turn. If there is voltage at the input, but there is no voltage at the output, then the FPS is faulty and needs to be replaced.Sometimes the drum stops spinning in the LG washing machine. In this case, turn off the machine, drain the water, open the door and try to turn the drum manually. If the drum does not rotate, then it is jammed. This situation can arise for various reasons. For example, on LG top-loading washing machines, doors may open and catch on a heating element or other part.

Sometimes the drive belt jumps off, which has to be replaced along with the bearing. The bearings themselves fail due to wear of the oil seal, which allows air and water to pass through due to the loss of elasticity. A foreign object may enter between the tub and drum and prevent rotation.When the drum is rotated by hand, but it does not rotate from the electric motor. The most likely reason is related to defects in the control modules. It is possible to solve the problem by resetting the program, but in more complex cases, the board needs to be repaired or completely replaced.Another reason may be the failure of the drive belt, due to breaks or loosening. Sometimes the brushes of the electric motor fail, and the motor itself turns out to be faulty under the influence of water leaks or voltage drops. More precise reasons for the failure of drum rotation are established only after disassembling the washing machine and diagnostics.After a certain time of operation, extraneous noises may appear in the LG washing machine, as well as uncharacteristic sounds in the form of a squeak, crackle and others. The main causes of extraneous sounds can be the following:Quite often, situations arise when, while observing all the required norms, regarding the amount of laundry, washing powder and settings, water is still drawn into the tank too slowly or not at all.In such situations, first of all, the presence of water in the system and its pressure, the position and serviceability of the valve for supplying water to the machine, as well as the condition of the water hose are checked. If everything is in order here, the washing machine must be freed from the laundry, disconnected from the power and diagnosed in order to identify malfunctions.The main reasons for the slow water supply:First of all, the correctness of the washing mode setting is checked. Some LG models have a no-drain mode option that may have been accidentally turned on. Next, the drain hose is inspected for kinks and blockages. If necessary, clean it, and at the same time check the siphon if water is drained through it.The reason for not draining the water can be a filter that is dirty and clogged with various objects.Draining is significantly hampered or completely stopped. A clogged filter often leads to more serious damage to the unit, therefore it must be inspected and cleaned regularly. In addition, some small items of clothing can get stuck in the pipe, obstructing the escape of water.A faulty pump, the sound of which becomes quieter in comparison with the usual mode, often becomes the cause of a violation of the drain. The machine makes a noise or hums, but the water does not drain. The malfunction occurs due to physical wear and tear of the pump, designed for 3-5 years of operation. Small objects leaking from the filter can jam the impeller.Sometimes all systems work fine, but the water is still not drained. The main cause is a blockage in the drain hose, which must be removed and cleaned. The second reason is associated with a pump that has exhausted its resource and is able to rotate only without water, dry. When water is supplied, it jams, power is lost, and it stops rotating.To avoid such situations, experts recommend taking a number of preventive measures:

Remove all foreign objects from pockets before washing.

The weight of the laundry loaded into the drum must strictly comply with the instructions, overloading is strictly not allowed.

Use only high-quality detergents in the right amount for washing.

We recommend using a stabilizer during washing. This will help keep your equipment safe from power surges and surges.

Water leakage in LG washing machines is one of the most serious malfunctions when you need to take the most urgent measures. Leaking water can not only flood the neighbors on the lower floor, but also damage the electronic parts of the unit. Therefore, if a leak is detected, the wash should be stopped immediately and the water drained. The water supply to the machine is completely shut off.The main reasons for water leakage in LG washing machines are:

A leak near the filter indicates poor tightening after cleaning, damage to the O-ring or thread.

Water appears mainly in the front of the machine and often spills out through the doors. This becomes especially noticeable during the spinning process. The cause of the malfunction may be a loose door or a damaged hatch seal.

If a leak occurs while draining the water, the leaking drain hoses must be replaced.

Leakage can occur due to a rupture of the inner pipe, depressurization of the connections, or a defect in the water pump. In these cases, water comes out centrally under the washing machine or closer to the front of the washing machine. If a leak is found near the rear wall, it is likely that the bearing or the sealing gland will fail.

When the flow starts with the water supply, the problem may be in the powder tray, which is clogged with detergent residues. It is possible that the inlet hoses and water inlets are also clogged.

The most difficult part of the LG washing machine is undoubtedly the control module. In case of failure, the control panel stops the execution of all functions of the washing machine. After all, this unit turns on and off the device, organizes the direct washing process, selects the mode, provides rinsing and spinning, at its command, the water is heated and cooled.Before you independently repair the control module, you must diagnose it. In case of obvious malfunctions, the machine does not spin the laundry normally, and the error code is not displayed on the display. The lamps located on the control panel at the same time or do not light up at all. Water is not drawn into the tank even if the required mode is set. The wash itself stretches for 3-4 hours in a row without stopping and switching to other modes. There are constant freezes of the device, there are difficulties with setting the necessary programs.

These and other signs gradually cause the complete inoperability of the washing machine. If at least one of them is available, the question of urgent repair of the control module should already be raised. Self-repair is recommended only to those people who have knowledge and experience with electronic circuits. In case of incorrect actions, the module will completely fail, and with it some components of the washing machine.If, nevertheless, a decision is made to repair yourself, you must follow a certain procedure:

The module is cleaned of sealant.

It is then carefully removed from the compartment away from the transformer.

After removal from the electronic module, the remainder of the sealant is removed.

Further, repair work is carried out.

After repair, a protective varnish is applied to the board sections.

In some cases, the module is not completely removed, only the necessary area is cleaned from the sealant, which is then repaired.

And everything is fine here? Moving further along the wire. You will need to remove the outer panels to check the terminal connections and ring the power cord. Just remember to unplug the power plug before doing this.

If your automatic machine has a mechanical timer, it may be the cause of the breakdown in it. Rotate the knob until you hear the drum spinning. If it works, then the unit is most likely burned out and will have to be replaced.

Another reason the washing machine won't turn on may be a closed intake valve. Make sure it is in the "open" position and that water enters the drum.

There may also be several reasons for this:

Heating element burned out.If this happens, the sequence of processes is lost and the washing does not start. The assembly needs to be replaced.
The belt drive has broken. We'll have to completely disassemble the machine to see this.
The water level or temperature sensors are out of order.
Burnt out processor. The washing machine does not receive any commands and does not understand what it needs to do.
Inlet valve defective. It may not open well or close tightly as a result of a blockage. It is necessary to remove the blockage, and so that the situation does not recur again, install an additional filter at the inlet.
The most unpleasant and expensive reason to repair is a burnt out electric motor. It will definitely not be possible to eliminate such a breakdown on your own, of course, if you do not know how to rewind electric motors.

If the washing machine does not draw water or does it very badly, there may be several reasons for this:

the supply valve is closed;
the inlet hose is clogged or deformed; you need to straighten it and clear the blockage;
the intake filter is coked; to clean it, turn off the water, disconnect the hose from the machine, remove the filter and rinse it under a strong stream of water, and then perform all the steps in reverse order;
the intake valve is clogged and out of order; you need to turn off the water and replace it;
the water level regulator is out of order; when the water level in the drum rises, the displaced air presses on the pressure regulator and the switch is triggered; if the system is clogged or damaged, no water will be drawn.

Another reason why the machine gets water into the machine very slowly or does not flow at all may be due to the low pressure in the system. This is not a breakdown and you will not be able to fix it with your own hands. As soon as the pressure in the system returns to normal, everything will correct itself. If this situation repeats regularly, then to eliminate it, you need to raise the pressure in the system. For example, equip a pressure tank in the attic of a private house or under the ceiling of an apartment.

If the washing machine stops during washing and does not finish it, there may be several reasons:

Most often, the washing machine does not spin the laundry because the drain system is clogged. To remedy the situation, you need to clean the filter and remove hair, threads and various small objects that have entered the system.

If it does not help, then the pump may have burnt out and the water from the tank is not pumped out.

When the water drains off normally, and the spinning does not work, then the drive belt is worn out or stretched. To fix the problem, it must be tightened or replaced with a new one.

Check the selected mode, perhaps the wash program includes a pause.
Inspect the drive belt. It probably jumped off or stretched out. Press on the belt to check the tension. Its offset should be approximately 12 mm. If your washing machine is equipped with a tensioner, loosen or tighten the belt to the correct level. In the case when such a design is not provided, the only way out of the situation is to replace the belt.
Pull on the loading door. If the latch is broken or jammed and the door does not close properly, the drum will not work. Open the door and close it abruptly again, press firmly. If all else fails, the lock is broken and needs to be replaced.
Ring the electric motor. It is likely that it burned out.

This malfunction can also be caused by several reasons.

Opening delay. The door of the washing machine may not open because the drum has not yet finished rotating and the washing program has not been completed. One or two minutes after the end of the process, the lock will unscrew itself.
There is still water in the tank. Many washing machines are programmed so that until the water is completely pumped out of the tank, the lock will not open. To open the door, you need to forcibly drain the water and check if the drain filter is clogged.After that, everything should work out.
The interlock switch is broken and needs to be replaced.

Such a malfunction can be determined by the nature of the sound that the machine makes. If you hear uneven metallic ringing, banging, or rattling that stops when the drum stops, it is most likely that small metal objects have entered the machine. These can be coins, nuts, keys that fell out of pockets. (See also: Why the washing machine makes a lot of noise during spinning)

A buzzing sound that becomes quieter when the door is pressed firmly indicates a broken latch. If it is not repaired in time, the door can jam at the most inopportune moment.

A squeal while the drum rotates indicates a slipping of the drive belt. Try to pull it on, everything should work out.

Crackling and knocking during drum operation indicates bearing wear. We'll have to replace the bearing in the washing machine. If this is not done, the shaft can be broken and the repair of the machine will be much more expensive.

In order to determine exactly where and how much it flows, you need to do a simple operation. Dry the floor and place a dry cloth under the machine. Run a short wash cycle without laundry or powder. Examine the rag carefully, you will see from which side you need to look for a leak.

The main reasons for the leakage of the washing machine can be due to: cracks in the hoses, loosening of the clamps, distortion or rupture of the seal on the door, and so on. If all parts of the machine are intact, the reason may be that the sewer is clogged and the water simply has nowhere to go.

First of all, you need to disassemble the machine and inspect the heating element. It is likely that too much scale has formed on it or that it has burned out. In the first case, it is enough to clean the heater from limescale, in the second case, the unit will have to be replaced. (See also: How to descale a washing machine)

If the automatic machine does not heat the water, then the reason may lie in the water level regulator. When the device is broken, the unit simply "does not understand" that there is enough water and it is time to turn on the heating element.

Another likely cause is a broken thermostat. It turns off the heating element even before the water heats up to the required temperature.

The most harmless reason may be choosing the wrong washing mode. See if the switch is in the rinse delay mode. It is also likely that the wash program has stopped due to a lack of electricity - check the plugs.

Another quickly removable reason that water does not leave the washer can be clogging of the filter or drain pipe, as well as its bending. Check and clean these parts and reconnect the clipper.

A clogged or broken pump is another cause of a malfunction. Forcibly drain the water, disconnect the pump, clean it or replace it with a new one.

The next reason due to which the washing machine does not drain the water may lie in the electrical part: any contacts have oxidized, the timer or water level switch is out of order. All these areas need to "ring" and, if necessary, replace the damaged part.

The first reason that the washing machine suddenly starts walking around the apartment is a strong overload. Remove some of the items from the drum and follow the instructions in the future. If there are not very many things, they may have got tangled and strayed into a lump. Untangle the knot and load the clipper more evenly.

If the washing machine jumps or vibrates when spinning even with a small amount of items, then the reason may be a break in the spring holding the drum. When replacing the spring, carefully inspect the counterweights that are bolted to the tank. It is possible that the fasteners are loose and the weights are loose. Correct the situation.

Also, the machine, which is not set according to the level, "starts to dance". Adjust the position of the washer using the feet. They have adjusting bolts.If they are not enough, just place a few sheets of thick cardboard in the right places.
