Basic error codes
Error codes in LG are displayed on the dashboard screen, facilitating further diagnostics and repairs. With their help, you can try to fix the breakdown yourself or at least consult with professionals by naming the error code.
No. 1. Problems with the water supply or drain system
Inscription Ae indicates an error turning off the device automatically. Occurs when a special float sensor is triggered. When it appears, the equipment should be checked for leaks. To do this, inspect all parts of the device in contact with water.
Also, for diagnostics, you can turn off the power of the machine for 15-25 minutes, and then turn it on again.
Possible causes of the error may be problems with the control unit, hatch cuff wearmechanical damage to the tank.
Letter combination FE 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:
- defect of the electrical controller;
- disturbances in the activity of the level switch;
- problems with the water inlet valve;
- a large amount of foam in the tank (if the wrong detergent is used).
To diagnose a problem, you need to check the sensor itself, pipe and wiring to make sure the pressostat is working properly.Then check the valve for a foreign object.
The code E1 means that water has leaked into the washing machine pan due to the depressurization of the tank.
Combination IE signals a lack of pressure. In this case, the water enters the tank extremely slowly, but still does not reach the required level in 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 applied to them);
- defective pressure switch;
- clogging of the filter of the intake valve (usually with lime sediment);
- holes and kinks in the hose;
- wiring at the intake valve;
- poor valve resistance (below 3 kOhm);
- breakdown of the general control board;
- the water supply hose is not installed correctly and partially blocks the water hole;
- insufficient pressure in the water pipes.
Pressostat Error PE similar to IE, but it arises not only because of the long filling of the tank with water. It also lights up if water has entered the machine too quickly (in 1-2 minutes).
In this case, you must also check the pressure of the water supply. If water is supplied in the usual way, it is necessary to diagnose the pressure switch. Another cause of the problem could be a short circuit or an open network on the line.
Malfunction OE associated with exceeding the permitted water level in the drum. Often the code is displayed in the event of an unsuccessful discharge, when part of the water has drained, but some of it remains inside the washing machine.
The code will automatically light up if the draining procedure lasts longer than 5 minutes. The problem occurs due to clogging in the drain path, namely: in the pipe, pump, filter, hose.
The drain hose may be twisted or squeezed. Drain problems sometimes occur due to air chamber punctures and a pressure sensor malfunction.
In some cases, the problems are not due to the washing machine itself, but due to blockages in the pipeline. To prevent this error, periodically clean the drain pipes.
UE - code of the imbalance of water in the tank.
To fix the problem, open the door and straighten some things, and then restart the wash.
In some cases, a similar problem arises from the small number of things in the drum, since the washing machine simply does not feel their weight. Then you should add more linen. If these steps do not help, you must test the electric motor wire, drive belt, controller and Hall sensor for damage.
No. 2. Engine Trouble Codes
Error code CE appears when the engine (electric motor) is overloaded and the drum is overloaded. For further operation, you need to remove part of the laundry from the machine. If, after releasing the drum, the device still does not work, and the display shows the same combination, it is necessary to check the health of the motor and the electronic controller.
For washing machine models that have a direct drive motor (DD mark), drum shake diagnostics should be performed. If he begins to twitch, then this will mean 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.
Number 3. Loading door and door errors
LE - Error blocking the hatch. It arises as a result of low voltage in the main power supply network or due to a faulty motor and controller.
As a diagnosis, you should check the closure of the door of the machine, the absence of chips of the door handle, the operation of the fuse of the door, the wiring of the lock. At the same time, you need to check the integrity of the rotor (whether there are cracks or tears) and the absence of foreign objects that prevent the drum from rotating.
Error code DE reports that the loading door is not fully closed.
To eliminate technical problems, check that the door is closed properly and slide it in more 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 fix the problem, you need to check the activity of two mechanisms: an electrical controller or a locking device for the hatch.
Number 4. Problems with the heater and power supply
Error code HE indicates a malfunction of the heater (heater). If the water heater is completely broken, you will have to replace it with a new one.
Also, a letter combination may indicate:
- insecurity of power circuits;
- temperature sensor breakdown;
- malfunctioning outlets 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 match the readings on the display, and also if the machine cannot be heated to the required values. This error indicates a heating circuit problem (including and TENA).
Error Pf indicates a power failure of the washing machine. This could be due to:
- improperly securing the power cord;
- loose plug connection;
- malfunctions in the connectors on the main control board;
- connecting the machine not to the outlet, but to the multi-function connector;
- damage to the heating element;
- violation of the wiring and connection of the protective filter.
SE - A code of a particular error, characteristic exclusively for washing machines with direct drive. It is also called a malfunction of the Hall sensor or tacho generator (needed to control the rotor speed of the washing machine).
In the event of a device breakdown, it should be replaced with a new one. Outwardly, the malfunction is characterized by malfunctions of the drum (the shaft does not rotate).
Letter code CL does not apply to error indicators, but appears on the display when the child lock function is set. The machine does not respond to pressing the buttons on the display and does not open.
Ee and E3 - These rare error codes for the LG washing machine most often occur on the display when first used during a test or when the device cannot determine the load.
Brief repair instructions
The 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 the washing machine does not work, then most often this happens due to the elementary lack of electricity in the power supply network.
Causes and simple troubleshooting
The rattling, knocking in the drum and vibrations often arise due to the unstable position of the legs. If you rearrange the machine, the problem will be resolved.
Also, a periodic knock during washing may indicate wear of the bearings and the stuffing box, which provides sealing of the drum. They can replace by yourself.
To accurately verify the cause of the noise, you should independently turn the machine drum left and right with your hands. If there is noise, crackling or crashing, then the cause is clearly in faulty bearings.
If the machine jumps or jumps, then this malfunction is due to violations in the structure of the counterweight mounting.
Water leaks occur due to wear on the hoses or incorrect connection. In this case, you can simply tighten the couplings in problem areas.
If water does not drain from the drum of the washing machine, the drainage system must be repaired: clean the filter, check the drainage hose and pump.
Features of diagnostics of work TENA
If the machine began to heat the water poorly, then it is necessary to conduct a diagnosis TENA. The fact is that during prolonged use, scale forms on the heating element, which impedes its normal operation. TEN can be easily cleaned even at home, for example, with acetic and citric acid.
Purification of TEN with citric acid:
- the washing mode without linen is set (temperature 60-90 degrees);
- instead of powder, citric acid should be poured (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 quarterly, depending on the intensity of the wash. For detailed instructions on cleaning the washing machine with citric acid, see this stuff.
- also sets the mode of washing without linen;
- 2 glasses of vinegar are poured into the powder receiver;
- start washing for the longest possible program;
- 5-10 minutes after the start of work, the machine should be paused and held in this position for about an hour;
- after an hour, you should resume washing and rinse the tank well to completely wash off the vinegar solution;
- then wipe the hatch doors with a piece of cloth dipped in acetic acid.
But it will be more effective to prevent the formation of scale. Prevention of pollution can be achieved through the installation of specific magnetic water softeners (filter softeners), which purify incoming water from calcium and magnesium salts.
To increase the life of the heater, certain rules should be followed: do not wash clothes in boiling water (if possible) and do not bring things to a state of deterioration and a very dirty look, because particles will fall into the heating element and form scale.
It is also recommended not to use cheap falsified detergents, but to select detergents and gels more selectively.
