LG Washing Machine (Front Load) PE error code

Difficulty: Medium · Cost: $20–$80 · Duration: 5–10m

The PE error means your LG washing machine cannot get a reliable reading from the water level sensor. This sensor tells the machine how much water is in the drum so it knows when to stop filling. When it malfunctions the machine cannot control the water level safely and stops the cycle. A simple reset fixes it in some cases. If the error keeps returning the pressure sensor or its connecting hose will need to be inspected by a technician.

Common causes

  • Water level pressure sensor has malfunctioned or failed
  • Air hose connecting the pressure sensor to the tub has come loose or is blocked
  • Temporary electronic glitch causing a false sensor reading
  • Excessive suds interfering with the pressure sensor reading

How to fix it

  1. 1

    Unplug the washing machine from the outlet and wait 10 seconds

  2. 2

    Plug it back in and restart the cycle to see if the error clears

  3. 3

    If PE returns check if you have been using too much detergent — reduce the amount and run a Tub Clean cycle

  4. 4

    If the error persists after resetting the pressure sensor or air hose needs inspection by a technician
