LG washing machine errors: popular fault codes and repair instructions

Diagnosing minor operational problems is a key feature of LG Eletronics washing machines.All devices of this brand are equipped with an intelligent control system, as this simplifies operation.

A significant achievement in the field of ease of use is recognized that errors of the LG washing machine are displayed in the form of combinations of Latin letters and numbers. Let's take a closer look at what errors signal.

Basic error codes

Fault codes in LG are displayed on the dashboard screen, facilitating further diagnosis and repair. With their help, you can try to fix the problem yourself or at least consult with professionals and name the error code.

No. 1. Problems with the water supply or drainage system

Inscription A.E. indicates an error in automatically turning off the device. Occurs when a special float sensor is triggered. If it appears, you should check the equipment for leaks. To do this, you need to inspect all parts of the device that come into contact with water.

Also, for diagnostics, you can turn off the machine’s power for 15-25 minutes, and then turn it on again.

Every user of a washing machine should have at least a schematic idea of ​​its structure. The instructions with diagrams that come with the new equipment can help with this.

Possible causes of the error may be problems with the control unit, hatch cuff wear, mechanical damage to the tank.

Letter combination F.E. lights up if the tank is full of water. In this case, the pressure switch (sensor) blocks the operation of the system.

Reasons for exceeding the water limit:

• electrical controller defect;
• disturbances in the operation of the level relay;
• water inlet valve problems;
• a large amount of foam in the tank (if the wrong detergent is used).

To diagnose the problem, you need to check the sensor itself, the pipe and the wiring to make sure that the pressure switch is working properly. The valve should then be inspected for the presence of a foreign object.

Code E1 means that water has leaked into the washing machine tray due to depressurization of the tank.

When diagnosing a problem, you should check hoses, pipes, calipers, etc. If all the mechanical elements of the device are working properly, it is worth checking the pump and leakage sensor for possible malfunctions

Combination I.E. indicates a lack of pressure. In this case, water enters the tank extremely slowly, but never reaches the required level within the allotted time (usually 4 minutes).

Possible causes of the problem:

• damage to the water inlet valve (it is worth checking the electromagnetic coils to make sure that voltage is supplied to them);
• pressostat defect;
• clogging of the water intake valve filter (usually with lime deposits);
• holes and kinks in the hose;
• wear of the wiring at the intake valve;
• poor valve resistance (below 3 kOhm);
• failure of the general control board;
• the water supply hose is not installed correctly and partially blocks the water hole;
• insufficient pressure in water pipes.

Pressostat error P.E. similar to IE, but occurs not only due to the long time it takes to fill the tank with water.It also lights up if water enters the machine too quickly (in 1-2 minutes).

In this case, you also need to check the water pressure. If water is supplied as usual, it is necessary to diagnose the pressure switch. Another cause of the problem could be a short circuit or a network break on the line.

If the PE code appears on the display during the first wash of the machine, then the problem may lie in the incorrect connection of the device to the sewer

Malfunction O.E. associated with exceeding the permitted water level in the drum. Often the code is displayed in case of unsuccessful draining, when some of the water has drained, but some of it remains inside the washing machine.

The code automatically lights up if the draining procedure lasts longer than 5 minutes. The problem occurs due to a blockage in the drainage tract, namely: in the pipe, pump, filter, hose.

After cleaning the drain system filter, the washing machine begins to function in operating mode. The pump (drain pump) may refuse to work due to breakdown, then it will need to be completely replaced

The drain hose may be kinked or pinched. Drainage problems sometimes occur due to punctures in the air chamber and a faulty pressure sensor.

In some cases, problems are not caused by the washing machine itself, but by blockages in the pipeline. To prevent this error from occurring, you should periodically clean the drain pipes.

UE — code for water imbalance in the tank.

The error often occurs when crumpled laundry is placed in the machine, which disrupts the functioning of the device. The machine cannot spin the drum without risk of breakage, and therefore stops operation due to an unbalanced load

To fix the problem, open the door and straighten out some items, and then start the wash again.

In some cases, a similar problem occurs due to a small number of items in the drum, since the washing machine simply does not feel their weight. Then you should add more laundry. If these steps do not help, you need to test the electric motor wire, drive belt, controller and Hall sensor for damage.

The cause of the error may also be incorrect installation of the washing machine, or rather its misalignment. Due to the unstable position of the legs, the device begins to vibrate and rattle.

No. 2. Engine problem codes

Error code C.E. appears when the engine (electric motor) is overloaded and the drum is overcrowded. For further operation, you need to remove some of the laundry from the machine. If, after releasing the drum, the device still does not work, and the display shows the same combination, you need to check the serviceability of the motor and electronic controller.

For models of washing machines that have a direct drive motor (DD mark), diagnostics should be carried out for drum vibration. If it begins to jerk, this will indicate a malfunction of the drive motor.

To prevent this problem, do not overload the machine. Each device has its own load limit in kilograms. Typically, information about it is located on the dashboard next to the display.

No. 3. Loading hatch and door errors

L.E. — hatch locking device error. Occurs as a result of low voltage in the main power supply or due to faulty motor and controller.

To restore operating functions, you can turn off the power to the device for 15 minutes and then turn it on again. Such a reboot often helps to return the machine to working order.

As a diagnostic, you should check that the machine door is closed, that the door handle is not chipped, that the door fuse is working, and that the locking wiring is working. At the same time, you need to make sure that the rotor is intact (there are no cracks or breaks) and that there are no foreign objects that prevent the drum from rotating.

Error code DE indicates that the loading hatch is not fully closed.

Door locks on LG cars often fail, but sometimes this combination only signals that the door is not tightly closed

To eliminate technical problems, you should check that the door is closed correctly and push it tightly.

In some cases, the door handle will need to be replaced due to damage, wear, or misalignment of the locking hook. If this does not solve the problem, you need to check the operation of two mechanisms: the electrical controller or the hatch locking device.

No. 4. Problems with the heating element and power supply

Error code HE indicates a malfunction of the heating element (heater). If the water heating element is completely broken, you will have to replace it with a new one.

Also, the letter combination can indicate:

• incompleteness of power circuits;
• breakdown of the temperature sensor;
• malfunction of the sockets to which the washing machine is connected.

Combination THOSE indicates problems with the temperature sensor (thermistor), when the actual temperature inside the tank does not correspond to the readings on the display, as well as when the machine is unable to heat the water to the required levels.This error indicates problems with the heating circuit (including heating element).

If breaks or short circuits are detected during diagnostics, the sensor must be replaced. In some cases, the cause of a temperature failure is a problem with the controller, so it should also be inspected

Error PF indicates a power failure in the washing machine. This could occur due to:

• improper fastening of the power cord;
• loose connection of the plug;
• problems with the connectors on the main control board;
• connecting the machine not to a power outlet, but to a multifunctional connector;
• heating element failure;
• violation of the wiring and connection of the protective filter.

S.E. - private error code, characteristic exclusively for washing machines with direct drive. It is also called a malfunction of the Hall sensor or tachon generator (needed to control the rotor speed of the washing machine).

If the device breaks down, it should be replaced with a new one. Externally, the malfunction is characterized by problems with the drum (the shaft does not rotate).

Letter code C.L. does not refer to error indicators, but is displayed on the display if the child lock function is set. The machine does not respond to pressing the buttons on the display and does not open.

The code combination for unlocking depends on the type of washing machine itself; it is always indicated in the operating instructions

E.E. And E3 - these rare LG washing machine error codes most often appear on the display during the first use during a test or when the device cannot detect the load.

Brief repair instructions

An LG machine is a reliable device, so when the first problems appear, you should try to eliminate the cause of the problem without opening the device.For example, if a washing machine does not work, then most often this is due to a simple lack of electricity in the power supply.

Causes and solutions to simple problems

Rattling, knocking in the drum and vibrations often occur due to the unstable position of the legs. If you rearrange the machine, the problem will go away on its own.

Also, periodic knocking noises during washing may indicate wear of the bearings and the seal that seals the drum. They can replace it yourself.

To be sure of the cause of the noise, you should independently turn the drum of the machine left and right with your hands. If noise, crackling or rumble appears, then the reason is definitely faulty bearings.

A properly installed washing machine will not “snort”! Over time, the balance adjusted during installation may be disrupted due to body movement during spinning.

If the machine jumps or jumps, then this malfunction is explained by violations in the structure of the counterweight fastening.

Water leaks occur due to worn hoses or improper connection. In this case, you can simply tighten the couplings in problem areas.

It often happens that even after cleaning the drain pump filter, the machine “refuses” to drain water. It is possible that the reason is a clogged drain hose, which just needs to be cleaned

If water does not drain from the washing machine drum, you need to repair the drain system: clean the filter, check the drainage hose and pump.

Features of work diagnostics heating element

If the machine begins to heat the water poorly, then you need to carry out diagnostics heating element. The fact is that during prolonged use, scale forms on the heating element, preventing its normal operation. The heating element can be easily cleaned even at home, for example, with acetic and citric acid.

Cleaning heating elements using citric acid:

• the washing mode without laundry is set (temperature 60-90 degrees);
• Instead of powder, you should add citric acid (about 100 grams, but it all depends on the degree of contamination of the device).

This procedure can also be used for preventive purposes - once every six months or quarter, depending on the intensity of washing. For detailed instructions on cleaning a washing machine with citric acid, read this material.

Cleaning with vinegar:

• also sets the washing mode without laundry;
• 2 cups of vinegar are poured into the powder receiver;
• run the wash program for the longest possible time;
• 5-10 minutes after starting work, you should pause the machine and keep it in this position for about an hour;
• after an hour, you should resume washing and rinse the tank thoroughly to completely rinse off the vinegar solution;
• After this, wipe the hatch doors with a piece of cloth soaked in acetic acid.

But it will be more effective to prevent scale formation. Pollution can be prevented by installing specific magnetic water softeners (softener filters), which purify the incoming water from calcium and magnesium salts.

Magnetic softeners are not affordable for everyone, so you can install a regular mechanical cleaning reagent filter on the pipe leading to the washing machine, which prevents rust and sand from entering the washing machine

To increase the service life of the heating element, you should adhere to certain rules: do not wash clothes in boiling water (if possible) and do not let things become worn out and very dirty, becauseparticles will enter the heating element and form scale.

It is also recommended not to use cheap counterfeit detergents, but to be more selective when choosing washing powders and gels.
