LG Washer error code PE
PE
What it means
Pressure sensor error - the pressure sensor has trouble detecting the water level.
Likely causes
- The pressure sensor cannot correctly detect the water level
- Moisture may be the cause if the washer is installed in a humid room, such as a bathroom
Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.
Safe first checks
- Unplug the power cord, wait five minutes, and reconnect it, then use the washer again
When to call a pro
If the PE error occurs again after reconnecting, request service from LG.
Repair or replace?
Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
