LG Dishwasher Error Code LE

The LE code on an LG dishwasher indicates a washing motor error. The control board has detected that the washing motor is operating abnormally, which can be caused by wiring issues, a blocked impeller, a defective motor, or a damaged controller board. The dishwasher stops the cycle automatically when this fault is detected to prevent additional damage.

A power reset may temporarily clear the LE error display, but the code will return if the underlying problem is not resolved. If the fault is caused by a momentary wiring connection issue, reseating the connectors and then resetting the unit may resolve it. For a locked impeller, failed motor, or damaged board, a reset alone will not fix the problem.

Repair costs vary depending on the root cause. If the fix is a simple wiring reconnection, costs may be minimal aside from a service call fee, which typically ranges from $50 to $100. Washing motor replacement parts generally range from $80 to $200, while a controller board replacement can range from $100 to $300 or more, with labor added on top if a technician performs the work.

Some causes of the LE error are DIY-friendly. You can check and reseat the wiring connections between the motor and controller, and you can inspect the wash pump impeller for debris or obstructions without specialized tools. If those steps do not clear the fault, diagnosing a failed motor or controller board typically requires more technical knowledge and a multimeter, and replacement of those parts may be better handled by a technician.

You should not continue running the dishwasher while the LE error is active. The dishwasher halts the cycle when this code appears precisely because the motor is not operating correctly, and forcing continued operation could worsen damage to the motor or controller board. Leave the unit off until the fault is diagnosed and corrected.
