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:
Video (click to play).
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 dampen 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, LG top-loading washing machines may open doors 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 in the LG washing machine, extraneous noises may appear, as well as uncharacteristic sounds in the form of a squeak, crackling 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, turned off 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 protect your equipment from power surges and surges.
Water leakage in LG washing machines is one of the most serious malfunctions when the most urgent measures are required. 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, a certain procedure must be followed:
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 of the sealant, which is then repaired.
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 understand 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 rubber 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.
