If your LG washer is displaying the “PE” error code, it typically indicates a problem with the water level sensor or pressure switch. The “PE” error, which stands for “Pressure Error,” occurs when the washer is unable to detect the water level properly during the cycle. This can disrupt the washing process and may require troubleshooting to resolve the issue.
Common Causes of the “PE” Error:
- Faulty Water Level Sensor: A malfunctioning water level sensor or pressure switch may fail to accurately detect the water level in the washer, triggering the “PE” error. This can be caused by electrical issues, sensor damage, or sensor calibration problems.
- Clogged Pressure Hose: Dirt, lint, or debris can accumulate in the pressure hose or air dome, obstructing the flow of air and preventing accurate water level detection. Cleaning or unclogging the pressure hose may resolve the issue.
