LG Washing machine PE error code – Wiring issue

If you have been getting a PE error on your LG washing machine, it is possible that there is a wiring issue. All you need to do is check the wiring harness which links the water level pressure sensor to the main control board.

  • Ensure that the wire harness isn’t loose, damaged or a burnt faulty one.
  • Use a multimeter to verify if you are getting proper continuity through the wire harness.
  • Change the harness wire that connects the water level pressure sensor to the main control board if it’s in a faulty state.

However, if you are able to get continuity and it’s securely connected, you can proceed to the second possible cause.

LG Washing machine PE error code – Faulty water level pressure sensor

In most cases, when the wire harness is secure, chances are that your water level pressure sensor is faulty and should be cleaned or replaced.

  • Firstly, you need to make sure that the water level pressure sensor is not caked with hard water or debris.
  • If you notice that the water level pressure sensor isn't clean, it will likely flash a PE error. So, you need to remove the sensor from the washing machine and wash it off for any hard water or debris.
  • Once cleaned, you have to put it back in the washer to conduct a test. If the machine runs smoothly without a PE fault code, the issue is likely fixed. However, if you notice that the sensor is faulty, you can replace with a new one. Make sure it's an OEM part.
