LG Dishwasher Error Code PE — Water Level Sensor Error
What this means
The PE error code indicates the water level pressure sensor (also called the pressure switch) is malfunctioning. This sensor monitors the water level inside the dishwasher tub. When it fails, the dishwasher cannot accurately determine how much water is inside, which may prevent it from filling or draining correctly.

2 stepsPower-cycle the dishwasher
Turn off the dishwasher. Unplug it or switch off the circuit breaker for 1 minute, then restore power and try starting a cycle.
Check the pressure sensor hose
The pressure sensor connects to the tub via a small hose. Check this hose for kinks, cracks, or blockages.
When to call a professional
This error typically requires a service technician to test and replace the pressure sensor assembly.
