How to eliminate PE error in LG washing machine?

  • Error: “PE”
  • Description: The “PE” error code indicates an issue with the washing machine’s pressure sensor, also known as the water level sensor or pressure switch.
  • Cause: This error typically occurs when the pressure switch is faulty or damaged.
  • Solution: Solutions can range from checking the sensor’s connections to replacing the pressure switch if it’s defective.

Encountering the “PE” error code on your LG washing machine can be concerning, but don’t panic. Here’s what this error means and how you can fix it.

What is the Pressure Switch and Why is it Important?

The pressure switch is a component in your washing machine that measures the water level in the drum. It ensures that the amount of water is appropriate for the selected wash cycle. If this sensor isn’t working correctly, it can send incorrect signals to the machine, resulting in the “PE” error code.

Steps to Resolve the “PE” Error Code

Checking Connections

  1. Unplug the Washer: Before any inspection, make sure to unplug the washer from the power source to prevent accidents.
  2. Access the Pressure Switch: The pressure switch is usually located at the top of the washer, and you’ll need to open the top panel to access it.
  3. Check the Connections: Ensure that the wires going to the pressure switch are properly connected and show no signs of wear or damage.

Cleaning the Pressure Switch

  1. Remove the Pressure Switch: Disconnect the wires and the hose going to the pressure switch.
  2. Clean the Hose: Sometimes, the hose connecting to the pressure switch can get clogged. Clean it carefully to ensure there are no blockages causing the issue.
  3. Inspect the Pressure Switch: If you have technical skills, you can try cleaning the pressure switch with compressed air. If not, it’s better to contact a technician.

Replacing the Pressure Switch

  1. Purchase a Replacement: If after checking and cleaning the pressure switch and connections the problem persists, you may need to replace the pressure switch.
  2. Install the New Pressure Switch: Place the new pressure switch where the old one was, connect the hose and wires.
  3. Test the Washer: Once the new pressure switch is installed, plug in the washer and run a test cycle to ensure the “PE” error has been resolved.

To troubleshoot the PE error code issue on your LG washing machine:

  • Disconnect the washing machine from the power supply for 10 seconds.
  • Reconnect the washing machine to the power supply and run a washing cycle.
  • Check the water inlet to ensure there are no obstructions, such as lint or twisted hoses.
  • Clean the water inlet filter and remove any residue that may be present.
  • Verify if there are any issues in the washing machine’s electrical circuit, such as burnt fuses.

If the problem persists after following these steps, it is advisable to consult the user manual or contact LG’s technical support for further assistance. If the issue persists, consider reaching out to a specialized technician for diagnosis and resolution.

Additional Tips

  • Consult the Manual: It’s always helpful to refer to your LG washing machine’s user manual for specific instructions on accessing and handling the pressure switch.
  • Contact a Professional: If you’re not comfortable performing these steps on your own, it’s advisable to contact a technician specialized in LG washer repairs.

Remember that preventive maintenance can help avoid such errors. If your LG washing machine displays the “PE” error code, follow these steps, and hopefully, your washer will be back up and running smoothly in no time.
