LG Washer Error Code 8

Error code 8 on an LG washer indicates a Locked Motor Error caused by a wiring problem in the motor harness. Specifically, the connection between the stator assembly and the main PWB assembly is open circuited, has poor contact, or is fully disconnected. The washer stops operation because the control board cannot communicate with the motor. Checking the 3-pin blue connector at the stator and the 3-pin gray GY4 connector at the main PWB is the recommended first step.

No, you should not continue running the washer while error code 8 is active. The error means the motor circuit is compromised, and attempting to operate the machine without a solid connection could cause additional damage to the motor, the control board, or the wiring. Stop using the washer and diagnose the harness connectors before running another cycle.

A reset may temporarily clear the code, but if the underlying wiring fault is still present, the error will return as soon as the washer attempts to run the motor again. Resetting without fixing the connector or harness issue is not a solution. The connectors in the motor harness must be inspected and the fault corrected before the code will stay cleared permanently.

Many cases of error code 8 can be resolved without professional service if the problem is a loose connector. Access the motor harness and firmly reseat both the 3-pin blue connector at the stator and the GY4 connector at the main PWB. If a wire is broken or a connector is corroded, the repair involves splicing or replacing the harness, which requires basic electrical skills. Stator or control board replacement is more involved and may warrant a service call.

If the fix is simply reseating a connector, there is no parts cost and minimal labor if you do it yourself. A replacement motor harness typically runs in the range of $20 to $60 in parts. A stator assembly replacement can cost between $80 and $200 or more in parts, plus labor if a technician is used. Main PWB replacement is the most expensive scenario, often ranging from $150 to $350 for the part alone.
