LG Washing Machine Error Code PE: Troubleshooting Guide and Solutions

LG washing machines are known for their reliability and advanced features, but like any other appliance, they can encounter issues from time to time. One common problem that LG washing machine owners may encounter is the error code PE. 

This error code indicates a problem with the water level sensor, which can affect the machine's ability to fill or drain water properly. 

In this article, we will delve into the details of the PE error code, discuss its possible causes, and provide troubleshooting steps to help you resolve the issue and get your LG washing machine back up and running smoothly.


Section 1: Understanding the PE Error Code

The PE error code on an LG washing machine stands for "Pressure Sensor Error." This code is displayed when the water level sensor detects an abnormal water level during the wash or rinse cycle. The water level sensor, also known as the pressure switch, is responsible for monitoring the water level inside the machine. It sends signals to the control board to control the water intake and drainage processes.

Section 2: Possible Causes of the PE Error Code

Several factors can trigger the PE error code on an LG washing machine. Understanding these causes can help you diagnose and resolve the issue more effectively. Some potential causes include:

Clogged or kinked water supply hoses: Check the water supply hoses connected to your washing machine for any blockages or kinks that may restrict the water flow.

Malfunctioning water inlet valve: The water inlet valve controls the flow of water into the machine. If it's faulty, it may not open or close properly, leading to water level issues and triggering the PE error code.

Faulty pressure switch: A defective pressure switch may fail to detect the correct water level, causing the machine to display the PE error code.

Overfilled or underfilled tub: If the tub is filled beyond or below the recommended level, the water level sensor may trigger the PE error code.

Section 3: Troubleshooting and Resolving the PE Error Code

Resolving the PE error code on your LG washing machine involves a series of troubleshooting steps. Here are some solutions you can try:

Check the water supply: Ensure that the water supply is turned on and the water pressure is adequate. Inspect the water supply hoses for any kinks or blockages. Clean or replace the hoses if necessary.

Inspect the water inlet valve: Test the water inlet valve by disconnecting the hoses and checking for proper water flow. If the valve is faulty, it may need to be replaced.

Examine the pressure switch: The pressure switch is usually located near the top of the machine. Check for any loose or damaged wires connected to it. If the switch is defective, it should be replaced.

Verify the tub's water level: Make sure the tub is not overfilled or underfilled. Adjust the load size and water level settings accordingly.

Power cycle the machine: Sometimes, a simple power cycle can help reset the machine's sensors and resolve temporary issues. Unplug the machine, wait for a few minutes, and plug it back in.

Contact LG customer support: If the PE error code persists after attempting the troubleshooting steps, it's recommended to reach out to LG's customer support for further assistance. They can provide additional guidance or arrange for a service technician to inspect and repair your washing machine.
