If a PE error appears on the display of the LG washing machine, it is necessary to take measures to eliminate the malfunction.
Electronic models of washing machines show a fault code on the display. Electromechanical SMAs without a screen notify of a problem by glowing (flashing) of the indicators “Washing” – “Rinse” – “Spin”.
Initially, the system gives an error on any program, but if the problem is started, the code will light up immediately after being turned on.
What does the error code mean and why does it appear
What does the PE error in the LG washing machine mean: malfunction of the water level switch (pressure switch). The system generates an error code after a 25-minute timeout, during which the water should have reached the minimum level. Or there was an excessively fast filling of the machine – in just 4 minutes.
Since such a malfunction can occur for other reasons, in this article you will learn how to fix the breakdown yourself.
The solution
- Malfunction of the electronic module. You can remove the PE error by disconnecting the machine from the power supply. Do a reboot for 15-20 minutes, then start the system. If this is the case, the error will be reset.
- Check the correct installation of SM LG. The reason for the simultaneous intake and discharge of water may be an incorrectly located drain hose. Check the connection of the hose to the machine, the drain level must be at least 50 cm from the floor. The video will help you install the LG machine correctly:
- Carefully inspect the wiring connecting the pressure switch to the control unit. If it is faulty, you need to isolate the damaged areas or replace the wires.

How to fix a breakdown
In 90% of cases, the cause of the PE error is a malfunction of the water level switch. You need to check it and replace if necessary.
How to do this to make sure the problem is fixed:
- Turn off the power supply to the LG washing machine (LG), turn off the water.
- Unscrew the bolts of the top panel of the washer, move it to the side.
- At the very top you will see a pressure switch. It controls the amount of water in the tank.
- Inspect the pressure tube for damage. Check the strength of the connection.
- Using a multimeter, you can check the wiring connecting the level switch to the controller.
- If everything is normal, you need to change the pressure switch to a working device.
Less commonly, the control module becomes the cause of a malfunction with a PE error. In this case, the error is on the display after switching on or when choosing a program. You can get the block by removing the front panel of the machine, where it is located.
If you see that the control board is burned out, it will have to be replaced. If the contacts are broken, they can be soldered. The main thing is to remember their location correctly.
Thus, you can fix the problem yourself. And if this is not possible, contact the service center.
