What the error code means

The PE error code on an LG front load washer typically indicates an issue with the pressure sensor or water level sensor. The pressure sensor/switch is used to detect the water level in the tub and ensure the proper amount of water is used for each wash cycle. If the sensor is faulty, damaged, or reading incorrect water level information, the control system will display the PE error code.

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts. 

Troubleshooting steps

Restart the washer

1. To clear a temporary error, unplug the washer from the power source and wait for about 1 minute.
2. Plug the washer back in and press the start button to begin a new wash cycle.
3. Check if the PE error code is still displayed on the control panel.

Check the water level sensor

1. Unplug the washer and access the control panel.
2. Locate the water level sensor, typically near or attached to the tub.
3. Inspect the sensor for any physical damage, such as cracks, loose wires, or corrosion.
4. Clean around and inside the sensor to remove any debris or residue.
5. Use a multimeter to test for continuity across the sensor’s terminals. If there is no continuity or significant fluctuations, the sensor may need replacement.
6. Ensure all wiring connections to the sensor are secure.
7. Reassemble the components and test the washer.
