Diagnosing minor malfunctions is a key feature of the 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 the 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 the errors signal.

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.

The main components of the washing machine
Each user of a washing machine should at least schematically represent its device. An instruction with diagrams that complements the new technique can help in this.

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.

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

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.

RE error on first run
If the PE code appears on the display during the first wash of the machine, then the problem may be the incorrect connection of the device to the sewer

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.

Drain pump filter clogging
After cleaning the system filter, the drain washer begins to function in operating mode. The pump (drain pump) may refuse to work due to a breakdown, then its complete replacement is required

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.

Crumpled laundry in the tank
An 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 the risk of breakage, and therefore stops the operation due to an unbalanced load

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.

The skew of the washing machine
The cause of the error can be the incorrect installation of the washing machine, or rather its skew. Due to the unstable position of the legs, the device starts to vibrate and rattle

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.

Machine Mode Setting
To restore working functions, you can turn off the device for 15 minutes, and then turn it on again. Such a reboot often helps restore the typewriter

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.

DE Error Code
In LG brand cars, door locks often fail, but sometimes this combination only signals a loose shutter

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).

Washing machine sensors
If during diagnostics breaks or short circuits are detected, the sensor must be replaced. In some cases, the controller may malfunction due to a temperature failure, so it should also be inspected.

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.

Child lock
The code combination for unlocking depends on the type of washing machine itself, it is always indicated in the instruction manual

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.

Installing the machine on the floor
A properly installed washing machine will not “snort”! Over time, the balance adjusted during installation may be disrupted due to the movement of the housing during the spin cycle.

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.

Possible clogged drain hose
It often happens that even after cleaning the drain pump filter, the machine “refuses” to drain the water. It is possible that the reason is a clogged drain hose, which you just need to clean

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.

Vinegar Cleaning:

  • 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.

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

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.

Conclusions and useful video on the topic

How to act on detecting a breakdown yourself and when you need the help of professionals, you will learn from a useful video.

Visual instruction for identifying errors in the operation of the washer by codes:

Almost all the malfunctions and breakdowns of the LG washing machine arise due to improper operation, therefore, to extend the life of the device, you should regularly preventive actions.

If a breakdown occurs, try to correct the situation yourself, but if complex repairs are required, it is better to contact a service center.

    In my opinion, LG is the best washing machine for the price! She has been working with my mother for about 7 years, no problems, but for us - 4 years, everything is wonderful too. The only drawback is that it periodically drives on the floor. This is a normal situation if, at the end of the wash, the machine runs into the middle of the bathroom. We were looking for a relationship of movements with the loading of the drum, but this is definitely not connected. We installed everything according to the instructions, even the masters called! Maybe someone has the same problem?

  2. Overall, happy with my LG. For 5 years of work, I have never returned for repairs. Minor problems were easily fixed by myself. Recently, an IE issue just appeared. The reason was the clogging of the intake valve filter. This happens because of too hard water. You can add citric acid when washing, it well corrodes scale. Calgon is just an advertisement, I don’t see the point of buying it, it’s easier to spend money on a good and high-quality powder.

    What an infernal scribe: you buy a typewriter so that it does its job - it erases. But instead, you get a Chinese hemorrhoids with parsing error codes. Awww! Manufacturers of technology! Nobody needs your jumping out of their pants in a consumerism race, only a fool will rejoice at features like rocking a drum in a Chopin waltz dachshund when he erases your cashmere sweater.

      Hello. If you buy a washing machine, be prepared for a complex system of its assembly and a large number of functional pribluda. It is clear that Chopin is only an additional function, although I have nothing against Tchaikovsky, but error codes sensibly help diagnose a breakdown indiscriminately. If you do not want the codes, ignore them the old-fashioned way, manually call the system or buy the activator “Oka”.
