LG PE Error Code — What It Means & How To Fix It

⚠️

What does the LG PE error code mean?

PE (Pressure Sensor Error) means the water level sensor is not functioning correctly. LG’s machine uses this sensor to know how much water is in the drum throughout the cycle. If it fails, the machine cannot accurately fill or drain, and will stop to prevent overflow or running without water.

How to fix the LG PE error code

Unplug the machine and remove the top panel.
Locate the pressure switch — a small round component near the top of the machine with a thin rubber hose attached.
Check the hose is firmly connected at both ends and has no cracks, splits, or kinks.
Disconnect the hose at the switch end and blow gently — you should hear a click from the switch. If not, the switch has failed.
Clean the hose if it appears blocked with limescale by flushing with warm water. Replace if cracked.
