What should I do if my LG washing machine shows an LE error?
The LE coding on the display of an LG washing machine often appears unexpectedly when nothing foreshadowed a failure. LE can occur at any stage of the washing machine operation.
But in most cases, the message appears on the display at the moment when water has been filled and the drum has been able to make even a few uncertain revolutions.

What does this LG washing machine code mean?
LE encoding indicates that the motor is blocked for some reason. It is impossible to immediately draw a conclusion about the seriousness of the breakdown. Some failures can be fixed quickly and easily, while others will require complex professional repairs with the replacement of entire components.
Causes, diagnosis, solution to the problem
Before embarking on a serious diagnosis of the LV, you can try a reboot. To do this, unplug the washing machine for 20 minutes and then turn it on again. If there was a failure of the control module, then after switching on again the situation may level out.
Drum overload
When washing silk, wool and underwear according to the rules, the loading should not be “to capacity”.
But if a lot of things have been compacted, LE occurs during spinning. To eliminate the problem, you should reduce the number of things in the drum.
A similar situation can arise when all the laundry in the drum has bunched up into one lump, which the washing machine itself cannot distribute evenly. The appearance of an error code indicates that the engine is overloaded.
Foreign object
If a foreign object gets into the LG drum and it blocks movement, rotation does not occur. It needs to be eliminated. It could be a key or a coin forgotten in your pocket or a popped underwire from a bra.
If you cannot get a foreign object from the side of the drum, you will have to partially disassemble the washing machine.
Tachogenerator failure
With such a failure, the drum does not rotate, but a hum is heard - the engine is trying to start, but it never starts working. The tachogenerator is present in LG cars with both belt drive and direct drive. Its task is to measure engine speed and transmit a signal to the control unit.
In devices with direct drive, the tachogenerator can still be repaired in some casesby replacing individual elements. In machines with a commutator type engine, the sensor is not repaired, but completely replaced. According to statistics, with an LE error, the breakdown of the tachogenerator is the most common situation.
How to replace the Hall sensor can be seen in the video:
Motor winding burnout
A motor is a unit that is responsible for the rotational movement of the drum. When the motor winding burns out, the drum does not rotate. To analyze the condition of the engine, it is removed. If the engine is worn out, a new one will be required.
The malfunction occurs due to one of the following factors:
- short circuit;
- factory defects;
- wear due to long-term use and loss of resistance.
A breakdown can take you by surprise. But sometimes it is preceded by unstable operation of the washing machine - with jerks when the drum rotates, overheating of the motor, etc.
Control module failure
If the LG control module malfunctions, the LE error on the display can appear at almost any stage. This can be either washing, spinning or rinsing.
The control unit itself is responsible for connections between nodes and coordinates their well-coordinated work. The cause of the failure may be moisture getting on the chip. with elements or short circuit in the circuit.
Repairing a module is a difficult and time-consuming task. To carry out diagnostics and repairs, the board is removed from the machine. If the damage is minor, then resoldering, replacing burnt out resistors, etc. is performed. But in cases where the board has completely become unusable, for example, the processor has melted badly or the processor has burned out, it is replaced with a new one.
Bearing wear
The drum and tank are a complex system, complemented by a large number of different parts. Bearings are an element that is actively involved in the process of drum rotation. If they wear out, the rotation of the drum may stop completely and the motor will be blocked.
Warning signs, which may indicate in advance a problem with the bearings:
- Extraneous knocking sounds when the drum rotates at high speeds, for example, during a spin cycle.
- Poor spin with sluggish drum rotation.
- Oily stains on things after washing.
- Work freezes.
- Uneven rotation of the drum - with jamming, grinding, etc.
The locking device has failed
If the UBL fails, then even with the hatch door completely closed, blocking does not occur. This type of damage is not considered serious. The solution to the problem is to replace the UBL.
Low voltage in the network
If the voltage in the electrical network is significantly lower than necessary for normal operation of the equipment, the engine may simply not start. But with such a problem, the washing machine does not require repair, and when the network voltage is restored, its operation will begin without additional manipulations.
Wiping the motor brushes
In LG belt drive washing machines, the motor's carbon brushes are used to rotate the drum. Over time, they wear out, and the contact is weaker.
When the carbon brushes become too worn, they spark and make a cracking noise, which in turn accelerates wear.
When the brushes are completely worn out, the drum stops rotating completely.. The washing machine may interpret this situation as an overload of the motor and issue an LE error.
The handle on the hatch door or the lock device is broken
If the handle is broken, deformed, or does not close the door properly, the machine may not even begin the wash cycle. The same problem will arise if the lock itself is faulty.
Broken wiring
Broken contacts and broken wires can cause the washing machine door to not lock if the UBL, lock and door handle are in good working order. To detect the location of contact failure a thorough inspection of the wires is necessary.
Call the master
To troubleshoot your LG washing machine, you can contact a company that provides washing machine repair services. It is convenient to search for companies on the Internet by filtering the request by the name of your city.
In order not to fall for scammers and not to doubt the quality of the repairs performed, you should contact companies that have been operating for several years and have many positive reviews. The cost of work to restore the functionality of an LG washing machine depends on the complexity of the breakdown and the complexity of the repair.
The average price is:
- replacement of the wiring harness – from RUB 2,000;
- door lock repair – from RUB 1,700;
- engine replacement – from 2,600 rubles;
- repair of the control module – from 2,100 rubles;
- removing a foreign object from the tank – from 1,600 rubles;
- replacement of the tachogenerator – from 2,600 rubles.
After the repair, the customer still has a guarantee for the work performed.
Recommendations
When the LE error code appears on the display of the LG washing machine and is looking for solutions to the problem, These tips will help:
- There is no need to rush to call a technician when you detect LE on the display. First you should reload the machine and calmly inspect it. Sometimes the problem can be solved very simply. For example, when a foreign object is visible from the drum and can easily be removed independently, interfering with normal movement.
- Some parts that have failed should not even be attempted to be repaired - it is better to replace them immediately. For example, a hatch handle.
- When installing new spare parts, preference should be given to quality parts.
- If you lack knowledge and experience, you should not begin serious repairs to the components of the washing machine - it is better to entrust such work to a specialist.

Conclusion
If your LG washing machine displays an LE error code, this may indicate a number of faulty situations. Some of them are associated with operating errors, but others can be serious breakdowns that only a specialist can handle.
