Cause 5Drive Motor

The drive motor might be defective. However, the drive motor is rarely at fault for this symptom. Before replacing the drive motor, first check all of the more commonly defective washer components. If none of those components are defective, consider replacing the drive motor. To determine if the drive motor is defective, first ensure that the motor is getting power. If the drive motor hums but doesn’t run, is noisy, or does not turn freely, replace it.

Cause 6Door Lock

The door lock secures the washer door shut during operation. Once the washer door is closed, the washer can begin operating. If the door lock is defective, the washer door will not latch properly. The door lock can fail either mechanically or electrically. Inspect the door lock for damage. If the door lock is damaged or does not latch properly, replace it. To determine if the door lock has failed electrically, use a multimeter to test each of the door lock switches for continuity.
