How to Fix / Troubleshooting
Safety: Unplug the washer before accessing the rear panel or motor.
- 1. Check drum movement: Rotate the drum by hand. It should move smoothly without grinding.
- 2. Inspect drive belt: Remove the rear panel and verify the belt is on both pulleys and not frayed or broken. Replace if worn.
- 3. Examine motor connections: Ensure the motor plug is fully seated and wiring is intact.
- 4. Test motor windings: Use a multimeter to check for proper resistance across motor terminals. Replace the motor if windings are open or shorted.
- 5. Control board/tach sensor: If the motor and belt are good, the tach sensor or motor control circuit on the board may be faulty. This is typically a level-4/5 repair requiring a technician.
