LE or CE Error Code

This error indicates a motor error. This may be an issue with the motor itself or a problem with the wiring harness between the control board and the motor. If either code persists, you will need to get the motor repaired through customer service. You can easily access this by going to the Request a Repair Page on the LG website.
