LG Washing Machine PE error code

PE stands for Pressure Sensor Error. It appears when the pressure sensor — the part that detects the water level — is malfunctioning and can't read how much water is in the tub.

Quick answer: LG washing machine error code PE: water level sensor fault — service likely needed. The most common cause is failed or faulty pressure (water level) sensor assembly. Try this first — power-reset the washer. If that does not clear it, move the washer out of a humid environment.

What causes the PE error?

  • Failed or faulty pressure (water level) sensor assembly
  • Moisture exposure from installing the washer in a humid room, such as a bathroom
  • Power disruption confusing the sensor reading

How to fix LG PE — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-reset the washer
    Unplug the power cord and wait 5 minutes before plugging it back in. This can clear PE if it was triggered by moisture or a temporary power disruption. Then try a cycle again.
    Safety warning: Do not repeat resets endlessly — if the code returns, stop and call service.
  2. Move the washer out of a humid environment
    If the washer sits in a bathroom or damp laundry area, relocate it to a dry, ventilated spot. Moisture on the sensor electronics can trigger PE.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • PE returns after the 5-minute power reset — this is the most common outcome and means a faulty sensor
  • Burning smell, sparks, or major water leaking
  • Anything requiring opening the washer's panels, testing the pressure sensor, or touching electrical components
