What does the code mean PE?
PE indicates a fault with the pressure sensor that reads the water level. LG suggests unplugging and restarting; if it persists, a technician is needed.
Code meanings can vary by model, market and appliance type. Always check your model's user manual. The same letters can mean something different on dishwashers or refrigerators.
