The simplest solution to remove the PE error code is to reset your washing machine. Here’s how to do a reset:
If a simple reset didn’t remove the PE error code, the next step is to check the wiring to see if there are any issues with it. Please note that inspecting the wiring will involve using a multimeter device. If you don’t have one and/or you are not experienced working with electronics you should call a qualified technician to come and inspect your appliance.
Here’s how to inspect the wiring:
If the wiring is fine, the next step is to check the water level pressure sensor itself to check if it has become faulty. The purpose of the sensor is to monitor the water level in your washing machine. If it becomes faulty your LG washing machine will display the PE error code and will stop working.
The steps to inspect the water level pressure sensor are:
Q: What do I do when I see a PE error code on my LG washing machine display?
A: The first thing to do is try and reset your LG washing machine. This can be done by unplugging your machine and leaving it off for three to five minutes before turning it back on again. If a reset doesn’t work, the water level pressure sensor wiring and the sensor itself will need to be checked to ensure they are working correctly. If faulty, they will need to be replaced.
Q: Why does my LG washing machine display a PE error code as soon as I press the start button?
A: This is usually the result of the control unit programmer not working correctly. When this happens it’s a good indication that the heating elements that control the water level pressure sensor switch are burnt out or defective. However, sometimes it can be the result of the unit processor itself becoming faulty which means it will need to be replaced.
Q: If the PE error code is showing on my LG washing machine, which components are faulty?
A: The PE error code indicates that either the wiring that connects the water level pressure sensor is faulty, or the water level pressure sensor itself is faulty. To find out which one is the cause of the error code, it will need to be tested and if defective, replaced.
Q: Why is the PE error code randomly showing on my LG washing machine?
A: This indicates a wiring problem within your LG washing machine and means the error code is showing by mistake. To fix this problem you will need to check the wiring between the water level pressure sensor and the heating element in your washing machine. If faulty, the wiring will need to be repaired or replaced.
