What the error code means

The error code “LE” on an LG dishwasher means that the main control board is unable to sense the rotation of the washing motor. This suggests an issue with the washing motor or wiring connection.

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

1. Ensure the dishwasher door is closing fully and latching securely.
2. Inspect the door gasket for any damage or debris that may be preventing a proper seal.
3. Make sure the door latch and strike plate are aligned correctly and functioning properly.
4. Locate the washing motor and its wiring harness connection on the back of the dishwasher.
5. Disconnect the wiring harness and inspect the pins for any damage, corrosion, or loose connections.
6. Reconnect the wiring harness, ensuring a secure and tight connection.
7. Remove the lower rack and access the filter assembly.
8. Inspect the filter and chopper for any food debris, hard water buildup, or other blockages.
9. Clean the filter and chopper thoroughly using warm water and a soft-bristled brush.
10. Reinstall the filter assembly, making sure it is seated properly.
11. If the door, wiring, and filter/chopper checks do not resolve the error code, the washing motor may need to be replaced.
12. Disconnect the power supply to the dishwasher and shut off the water supply.
13. Locate the washing motor, located at the bottom of the dishwasher tub.
14. Disconnect the wiring harness from the motor and remove any mounting screws or clips holding the motor in place.
