How to Fix Error PE — Step by Step

1. 1

   Reset the Washing Machine

   Begin by unplugging the washing machine from the power outlet. Next, locate the reset button on the control panel, usually marked with a small diagram of a circle with an arrow. Press and hold the reset button for 5-10 seconds. Release the button and plug the washing machine back in. This may resolve the issue, but proceed with caution if the error persists.

   💡 Pro Tip: Make sure to unplug the washing machine before attempting any repairs to avoid electrical shock.

2. 2

   Check the Water Level Sensor

   Locate the water level sensor (pressure switch) behind the washing machine's front panel. Remove the Torx screws (T20) to access the sensor. Use a multimeter to measure the resistance between the sensor's terminals. A reading of around 1-2 kΩ indicates a functioning sensor. If the reading is significantly different, replace the sensor.

   💡 Pro Tip: When measuring resistance, ensure the multimeter is set to the correct range (20 kΩ or higher) to avoid inaccurate readings.

3. 3

   Inspect the Sensor's Wiring

   Inspect the wiring connected to the water level sensor for any signs of damage, corrosion, or loose connections. Check for any frayed wires or broken insulation. If you find any damage, replace the wiring harness.

   💡 Pro Tip: When inspecting the wiring, use a flashlight to illuminate the area and look for any signs of wear or damage.

4. 4

   Check the Sensor's Mounting

   Verify that the water level sensor is securely mounted to the washing machine's frame. Check for any signs of looseness or movement. If the sensor is loose, tighten the mounting screws or replace the mounting bracket if necessary.

   💡 Pro Tip: When tightening the mounting screws, ensure they are snug but do not overtighten, which may damage the sensor or surrounding components.

5. 5

   Replace the Water Level Sensor

   If the sensor is faulty or damaged, replace it with a new one. Consult the user manual or online resources for specific instructions on replacing the sensor. Ensure the new sensor is properly connected to the wiring harness and securely mounted to the washing machine's frame.

   💡 Pro Tip: When replacing the sensor, make sure to dispose of the old sensor responsibly and follow proper safety procedures when working with electrical components.
