Guide on PE Error Code on LG Washing Machines: Diagnosis and Solutions

Sometimes, LG washing machines may encounter occasional issues, and the PE error code is one such challenge users may face. Let’s try to delve into guide and explore when the PE error code occurs, identify the responsible components, and provide effective solutions to resolve this problem.

When does the PE Error Code Happen

The PE error code typically occurs when there are issues with the water level sensor or pressure switch in the washing machine. 

This code is triggered when the machine is unable to detect the water level correctly, leading to potential problems during the washing cycle.

Components Responsible for the PE Error Code

PE error code may be potentially emerge only because of water level sensor:

• Water Level Sensor (Pressure Switch): The water level sensor, also known as the pressure switch, monitors the water level inside the drum. Anomalies in this sensor’s readings can trigger the PE error, indicating a potential water level detection issue.

Water Level Sensor	Monitors the water level in the drum for precise washing cycles.

How to Fix the PE Error

You need a systematic approach to address issues caused by water level sensor. Here’s a step-by-step guide:

Pause and Restart the Cycle:

• If the PE error occurs mid-cycle, pause the machine, and restart the cycle. This can sometimes reset the sensor and resolve temporary glitches.

Check Water Supply:

• Ensure a consistent and sufficient water supply to the washing machine. Insufficient water levels or water pressure can lead to inaccurate readings by the water level sensor.

Inspect the Water Inlet Valve:

• The water inlet valve controls the flow of water into the washing machine. Check for any clogs or malfunctions in the valve that may hinder proper water intake. Replace the valve if necessary.

Examine the Water Level Sensor:

• Inspect the water level sensor for any visible damage, loose connections, or debris. Clean the sensor and its surroundings to ensure accurate readings. If issues persist, consider replacing the water level sensor.

Check for Blockages:

• Inspect the drain hose and pump filter for any blockages. A blocked drainage system can interfere with water levels and trigger the PE error. Clear any obstructions to ensure smooth water flow.

Run a Calibration Cycle:

• Some washing machines allow users to run a calibration cycle. Refer to the user manual for instructions on initiating a calibration to reset the water level sensor.

Conclusion

The PE error on LG washing machines is primarily associated with issues related to the water level sensor or pressure switch. By systematically addressing problems with water supply, the water inlet valve, and the sensor itself, you can solve this problem without any obstacles.
