What should I do if my LG washing machine shows an LE error?

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 load should not be “full .

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 forgotten in your pocket, a coin , or a popped-out bra wire.

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.

The reason for the appearance of LE may lie in the failure of the Hall sensor or the resistors that are associated with it. Such sensors control the rotation of the drum. When they break, movement does not occur. The solution to the problem is to replace parts.

In devices with direct drive, the tachogenerator can still be repaired in some cases by 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 microcircuit with elements or a 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 that may indicate a bearing problem in advance:

1. Extraneous knocking sounds when the drum rotates at high speeds, for example, during a spin cycle.
2. Poor spin with sluggish drum rotation.
3. Oily stains on things after washing.
4. Work freezes.
5. Uneven rotation of the drum - with jamming, grinding, etc.

The solution to the problem is to replace the bearings. Such a breakdown is insidious in that other components of the washer also suffer from it, which may also require repair later.

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 mains voltage is restored, its operation will begin without additional manipulations .

Wiping the motor brushes

In LG belt-driven 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.

All these parts are easy to change and are relatively inexpensive. Most often they are not repaired, but new ones are installed.

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 .

What to do to solve the problem

Before fixing the problem, let’s look at the reasons for issuing the code and how to solve the problem. What to do:

• Check the washer door for tightness. Press the hatch tightly until it clicks.
• If an error appears on the “Spin” program during a delicate wash, the tank is probably overloaded with laundry. You need to reduce weight by taking away some of your clothes.
• Unplug your LG washing machine (for no more than 20 minutes), then turn it on. This should clear the error.
• Possible foreign object entry. If it gets stuck between the tank and the drum, it creates a mechanical blockage. To remove the item, you will have to disassemble the washer tank.
• Check the mains voltage. Maybe there is not enough power for the machine to operate correctly, or the wiring is broken and needs to be replaced.
• There was a power surge in the network. If this happens often, the PF code will appear on the display alternately with the LE error, which means “energy failure.” Rebooting the system or installing a stabilizer may help.

How to fix the problem if the error is not reset? Repairs that you can do yourself will help.

Signs of a malfunction will tell you what to repair.

Tachogenerator failure

This device is responsible for the engine rotation speed. If the tachometer fails, the machine begins to hum strongly, does not turn the drum, and the LE error appears on the display. It is necessary to check the tachogenerator and replace it if necessary.

Problems with the control module

A sign of a breakdown is that the LGI machine stops working in the “Wash”, “Rinse” or “Spin” modes, after which the system displays an LE error. Remove and check the module, if possible, repair it. If the part is faulty, replace it.

Motor winding problems

If the winding burns out, the LE error appears on the display, and the washing machine does not spin the drum at all. You will have to replace the stator or motor.

The door won't close

The hatch door does not close or is not locked, the SM displays a fault code. The lock or door handle may be broken and require replacement. There may also be a contact failure in the UBL circuit.

Check the wires and replace them with good ones.

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.

Recommendations

When an LE error code appears on the display of an LG washing machine and is looking for solutions to the problem, the following tips will help:

1. 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.
2. 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.
3. When installing new spare parts, preference should be given to quality parts.
4. 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.

You will find a lot of important and useful information about error codes for LG washing machines in this section.

Possible causes of the LE error

As noted above, there are quite a few reasons for the occurrence of the LE error. These reasons are, one way or another, related to the electrics of the LG washing machine. Before looking for the reason why this error occurs, look at what moment this error occurs - when starting the machine, during operation at maximum load on the electric motor, or at any of the indicated moments. All this is very important. So, what are the reasons why the LE error appears?

• Problems with the sensor or motor winding. If the electric motor sensor does not make good contact or its winding is broken due to overload, the display may show a CE or LE error.
• The wiring that supplies power to the engine is broken or does not make contact.
• There is a problem with the power filter of the LG washing machine.
• Voltage drop in the electrical network. If drops occur frequently, then the LE error will pop up often, perhaps it will alternate with the PF error.

Important! The special PF error on LG washing machines occurs quite often and means “Failure in the power supply to the network.” This error can be eliminated by rebooting the machine, but if it occurs frequently, you should think about buying a stabilizer.

Procedure for checking the electric motor and wiring

Only a real master can immediately guess the nature of the LE error. To do this, we need to get to the engine of the LG washing machine, test it for faults, test the wiring, and only then draw conclusions. First we need to get to the washing machine motor.

1. We disconnect the washing machine from communications and turn its back wall towards us.
2. Unscrew the fasteners holding the back wall and remove it.
3. The motor on LG direct drive washing machines looks different and is located directly in the center of the drum. We find the engine - it is a large round metal disk located in the very center and begin to check it.

Repairing and checking the washing machine engine is described in detail in the article of the same name, which you can read on our website. We will not describe the process again. It’s better to talk about how to check the wiring through which power is supplied to the motor, because direct drive motors are very reliable and it is less likely that they are the problem.

• We find two bundles of wires going to the engine and disconnect them.
• We take a device called a “multimeter” and check the resistance of each wire.
• If you find a broken wire, consider that the problem was there; if the wires are intact, you need to look further.

Important! If the wire is intact, then the multimeter display should display zero; if it is broken, then 1.

Checking the surge protector and understanding the electrical network

The LE error may be caused by faults in the washing machine's power filter. What to do in this case? How to check the surge protector for short circuits. First, you need to get to it.

1. Remove the top cover of the LG washing machine.
2. The surge protector is located on top, exactly in the place where the power cable is connected.
3. We check the contacts of the filter and the wire for breakdown with a multimeter. If the surge protector is working, you need to look further.

error can also be caused by an unstable power supply. Our Russian electrical networks are simply designed to disable electrical appliances. Constant failures and power surges break equipment not only in individual houses or apartments, but also in entire neighborhoods. How to protect your “home assistant” and other equipment from such risks? It is necessary to install a difavtomat and a stabilizer for the washing machine.

In general, it is better to have a professional electrician check the wiring in your home and install the necessary protections. It is better, of course, to do this before purchasing a washing machine, so that later its connection will be as safe as possible. Serviceable and suitable electrical wiring and means of protecting electrical networks are the key to uninterrupted operation of the washing machine.

To summarize, we note that the LE code, which suddenly appears on the display of the LG washing machine, can be generated by various malfunctions, but they are all related to the electrical system, and not to the water supply, as code 1E tells us. Be careful and decipher error codes correctly.
