LG Washer Error Code 9

Error code 9 on an LG washer indicates a locked motor error. The washer's control system has detected that the drive motor is not responding correctly, which can be caused by a disconnected or damaged motor harness connector, an open circuit in the wiring, or a defective hall sensor on the stator. The machine shuts down motor operation when this condition is detected to prevent further damage.

No, you should not continue running the washer while error code 9 is active. The motor is not operating correctly, and running the machine could cause additional damage to the motor, control board, or wiring harness. The washer has stopped as a protective measure, and it should remain out of service until the fault is diagnosed and repaired.

Unplugging the washer for a few minutes and restarting it may temporarily clear error code 9, but the fault will return if the underlying problem has not been fixed. A reset does not repair a loose connector, open-circuit harness, or defective hall sensor. If the error reappears after a reset, a proper diagnosis of the motor wiring and components is necessary before the machine will operate reliably.

Some causes of error code 9 can be addressed without professional help. Start by checking the 3-pin white connector at the stator and the 4-pin white connector at the Main PWB Assembly to make sure both are fully seated and undamaged. If the connectors are secure and the error persists, further diagnosis requires a multimeter to test harness continuity, which is within reach of experienced DIYers. Hall sensor or control board replacement is more involved and may warrant a professional technician.

Repair costs depend on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost at all, though a service call typically runs between $75 and $150. Replacing a damaged wiring harness or hall sensor generally adds $50 to $200 in parts. A Main PWB Assembly replacement is the most expensive scenario, with parts and labor potentially ranging from $200 to $450 or more depending on the model.
