LG washer PE error

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:

  1. 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.
  2. 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.

Troubleshooting Steps to Resolve the “PE” Error:

  1. Check the Water Level Sensor: Inspect the water level sensor or pressure switch for any signs of damage or wear. Test the sensor’s functionality according to the manufacturer’s instructions and replace it if necessary.
  2. Inspect the Pressure Hose: Locate the pressure hose connected to the water level sensor and check for any kinks, bends, or obstructions that may be preventing proper airflow. Clean or unclog the pressure hose as needed to ensure accurate water level detection.
  3. Reset the Washer: Try resetting the washer by unplugging it from the power source for a few minutes, then plugging it back in. This can sometimes clear minor electronic glitches that may trigger error codes.

Professional Assistance:

If the “PE” error persists after troubleshooting, or if you’re unsure about performing repairs yourself, it’s recommended to contact a qualified technician or LG service center for assistance. They can diagnose the issue accurately and perform any necessary repairs to restore proper water level detection to your washer.
