The sensor behind PE
Leaks are guarded against by a sensor that monitors the water level in an LG dishwasher. PE reports an issue with that sensor, and the manual ties the code to certain older models.
What to do
A service technician has to inspect PE.
Request service; there is no adjustment for you to make.
From San Francisco to the rest of the Bay Area, (415) 223-7887 is the number to dial about LG dishwasher repair. Bring up PE and your model number when you call, since older units vary.
Model compatibility: LG reuses codes across series and model years, so PE 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
PE reports a water level sensor issue on certain older LG dishwasher models.
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.
