Troubleshooting Tips: Why Does My LG Washing Machine Display PE?

LG washing machines are renowned for their efficiency and reliability. However, users may occasionally encounter an enigmatic “PE” error code, leaving them perplexed and unable to complete their laundry tasks. This comprehensive blog post delves into the underlying causes of this error and provides effective solutions to resolve it.

What Does “PE” Mean?

The “PE” error code in LG washing machines typically indicates a problem related to water pressure. It can occur when the water pressure is too low or too high, preventing the machine from operating correctly.

Causes of “PE” Error

1. Low Water Pressure:

An insufficient water supply can trigger the “PE” error. This may be due to:

• Clogged water inlet hoses
• Faulty water supply valves
• Low water pressure in the home

2. High Water Pressure:

Excessive water pressure can also cause the “PE” error. This can occur if:

• Water pressure regulator is malfunctioning
• Kinked or blocked drain hose

How to Fix “PE” Error

1. Check Water Supply:

• Ensure that the water supply is turned on and the hoses are not kinked or blocked.
• Clean any debris from the water inlet filters.

2. Inspect Water Pressure:

• Contact your local water utility to confirm whether the water pressure is within the recommended range (10-120 psi).
• If the water pressure is too low, contact a plumber to resolve the issue.
• If the water pressure is too high, install a water pressure regulator.

3. Reset Washing Machine:

• Unplug the washing machine and wait for a few minutes.
• Plug it back in and start a new wash cycle.

4. Check Drain Hose:

• Ensure that the drain hose is not kinked, blocked, or submerged in water.
• Clean any debris from the drain hose and ensure it is properly connected to the drain.

5. Inspect Water Level Sensor:

• If the above steps do not resolve the issue, the water level sensor may be faulty.
• Contact a qualified technician to diagnose and replace the sensor if necessary.

Other Possible Causes of “PE” Error

1. Faulty Pressure Switch:

• The pressure switch monitors the water level in the washing machine.
• A malfunctioning pressure switch can send incorrect signals, leading to the “PE” error.

2. Malfunctioning Control Board:

• The control board is the brain of the washing machine.
• A faulty control board can disrupt communication between components, causing the “PE” error.

3. Water Valve Solenoid:

• The water valve solenoid controls the flow of water into the washing machine.
• A malfunctioning solenoid can prevent water from entering the machine, triggering the “PE” error.

When to Call a Technician

If you have tried the above troubleshooting steps and the “PE” error persists, it is advisable to contact a qualified LG washing machine technician. They have the expertise and tools to diagnose and repair the underlying issue effectively.
