LG washer error codes

Most modern LG washing machines include the function of displaying an error code in the event of some malfunctions. Quite often, understanding what the error code means, the user is able to fix the damage himself without resorting to the help of service personnel. For your convenience, we present the listing of the error codes of LG washing machines with decoding of each specific code. Also, the table includes a description of the error, the reasons for its occurrence and possible solutions.

Error codes associated with a set of water and drain the water

The washer won't fill at all. Even the first level is not reached in 4 minutes

The possible causes are the following ones:

  • The water is not entering the washer. Why? The water tap is closed, the water pressure is weak, the hose is damaged or clogged, or the inlet valve is clogged etc. You can fix all these faults yourself
  • You've failed to tightly close the door, and the electronics is controlling the start of the washing cycle
  • The inlet electrovalve is faulty. You need to replace it
  • The water level sensor is malfunctioning. It requires a diagnosis and subsequent replacement
  • The circuit is open, or the contacts are disconnected. We mean the contacts of the circuit containing the controller and the inlet valve/the water level switch
  • The controller is malfunctioning. The professional diagnosis and replacement is required if the board is faulty

More about error IE

The water has exceeded the permissible filling amount

Troubleshooting: 

  • The system is failing to drain dirty water. Either the washing machine is installed improperly ("syphoning"), or the drain system is clogged
  • The water intake valve is faulty. You need to diagnose and replace the valve
  • The water level sensor (pressure switch) is clogged or defective
  • The controller is malfunctioning

More about error FE

The system is failing to drain dirty water. The water hasn't dropped to a certain level in 5 minutes

The reasons are as follows:

  • Something is stopping the water from leaving the washer: a defect or clog of the drain hose or the clog in the hydraulic system of the drain pump. You can fix all these things yourself.
  • Either the circuit is open, or the contacts are disconnected. They are the contacts of the circuits containing the controller and the pump/the pressure switch. A similar problem may occur in the power circuit of the pump motor
  • The drain pump is malfunctioning. You need to call a specialist for checking and replacing the coil or the entire motor
  • The water level switch is faulty. It requires diagnosis and subsequent replacement
  • The controller is malfunctioning. The professional diagnosis and replacement is required if the board is faulty

As you can see, there are many reasons for this error code to appear, so you'd better call a qualified specialist.

Error codes of various sensors

The water level sensor  is defective

The error occurs in two cases. The first one is when the water hasn't reached the nominal level in a timely manner (after more than 25 minutes). The second one is when the washer has been filled with the entire amount of water too fast (less than in 4 minutes).

  • The sensor is faulty. You need to diagnose and replace the sensor
  • The contacts are disconnected or the sensor circuit is open. Check the wiring with a multimeter and repair it, tighten the contacts
  • The controller is malfunctioning. It is necessary to check it carefully and replace it if faulty

More about error PE

The Hall sensor of the motor is defective

The reasons for the malfunctioning sensor are common.

  • First, make sure that the wiring between the sensor and the controller is intact. Also, check if all the contacts are connected and the terminals are not oxidized
  • No signal from the sensor may indicate its malfunction. You need to replace the faulty sensor
  • The controller is malfunctioning. It requires professional diagnostics and controller replacement

More about error SE

The sensor has detected some water in the bottom of the washer (the Aqua Stop system is activated)

The following units of the washer may cause the problem:

  • Check all the places in the washer the water can leak from: the fill and drain hoses, the door and its gasket, the detergent drawer, the inner pipes, and the tub
  • The drain pump is leaking. It is likely to be beyond repair so you will have to replace it
  • The Aqua Stop sensor is faulty. You need to check and replace the defective one

Error codes associated with water heating

A heating problem is detected, or the temperature sensor is faulty

As a result, the water temperature will differ from the designed one, which will affect the quality of washing.

  • First, make sure that the wiring between the sensor/the heating element and the controller is all right. Check if all the contacts and connectors are connected securely
  • No signal from the sensor may indicate its malfunction. You need to replace the faulty sensor
  • The controller is faulty. It requires professional diagnostics and controller replacement

More about error tE

The water is not heated, most likely due to the faulty heating element

There are many reasons for that, here are some of them:

  • The mains voltage is too low: see the description of the F14 error code
  • The heating element has burnt out, for example, because of the thick layer of the scale accumulated on it. The heater is beyond repair
  • A power circuit of the heating element is open. Check the wiring and the contacts
  • No signal from the temperature sensor may indicate its malfunction. You need to replace the faulty sensor
  • The relay of the heating element got "stuck". It needs replacement as well
  • Oddly enough, the heating period may be too short for the water temperature to rise if the washer is located in a cold place. It's a rare case, but it happens
  • The controller is faulty. You cannot fix it yourself – call the service shop

Error Codes associated with the door and drum washing machine LG

No signal is received that the door is locked

As a result, the electronics is controlling the start of the cycle. The possible causes are the following ones:

  • First, the most obvious thing is  to close the door tightly
  • Then make sure that no obstruction prevents you from closing the door. If the error is still there, then something is broken
  • The connection is broken between the control triac of the lock assembly and the controller. You need to check the circuit with a multimeter and check the contacts
  • A lock assembly element is faulty, for example, the lock. In principle, you can repair the lock yourself. Still, the lock assembly is a complex part including electronics, so you'd better contact the service center
  • The door look sensor is defective. It needs replacement
  • The controller of the lock assembly is faulty. You need to replace it.

More about error dE

The drum position is wrong, there is no balance

The possible causes are the following ones:

  • You have probably placed the laundry in the tub in a wrong way so there is no balance
  • The drive belt of the electric motor of the washer is damaged. It needs replacement
  • he wiring of the washer is faulty. You need to check the circuit with a multimeter, fix the defective sections, check the contacts, and tighten them
  • · The drum position sensor is defective. You need to diagnose and replace the sensor
  • · The control module is malfunctioning. Call the handyman to check it out.

More about error UE

The door is not locked

The reasons are similar to the dE error. In addition, the low voltage may be the case.

More about error LE

The drive motor is overloaded

On direct drive washers, the error can occur alongside with the drum jerking.

  • You have probably loaded too much laundry into the tub
  • The control circuit of the motor is defective. Check the section with the multimeter, tighten the contacts, and repair the wires
  • The drive motor is defective. It requires diagnosis, replacement of the tachogenerator or the entire motor
  • The board controlling motor rotation is failing. It needs diagnosis, repair or replacement
