Error codePE, E33
ApplianceWasher
Quick answer
PE (E33) is a water level or pressure sensor fault on LG washers; a power reset is the first step.
Model compatibility: LG reuses codes across series and model years, so PE, E33 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Water level (pressure) sensor fault: the washer cannot detect the water level properly.
PE and E33 point to the water level sensor, also called the pressure sensor. The washer cannot measure how much water is in the tub. Front-load washers and WashTower units are covered first, then top-load washers.
Front-load and WashTower washers
Unplug the washer for 10 seconds, then plug it back in and restart the cycle.
On a WashTower, moisture in the air, particularly in a humid room such as a bathroom, can cause PE. Unplug the cord, wait 5 minutes, reconnect and start the unit.
If PE keeps appearing, the unit needs service.
Top-load washers
PE here means the washer cannot detect the water level properly, from humidity or oversudsing. Too much detergent or softener can cause it. Unplug for 5 minutes, and if oversudsing is the cause, run a tub clean cycle. A technician may need to inspect the unit if that does not fix it.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
