How to fix it
- Unplug the washer and rotate the drum by hand — it should spin freely.
- Remove the rear access panel to expose the motor.
- Inspect carbon brushes; replace as a pair if under 8 mm long.
- Check the tachometer coil resistance (typically ~70 ohms).
- Reseat all motor connectors and check for burnt pins.
- Test motor windings; replace the motor if shorted.
- If motor tests good, replace the motor control board.
Why it happens
Typical signs: Drum will not turn · Loud humming with no movement · Cycle stops during agitation or spin · Burning smell
- Worn motor carbon brushes Common after 8-10 years; brushes wear below minimum length.
- Faulty motor tachometer (speed sensor) Hall sensor on the motor rear fails to report RPM.
- Damaged motor windings Shorted or open winding causes overcurrent trip.
- Loose motor wiring connector Vibration loosens spade or molex connector at the motor.
- Motor control module (inverter) failure Drive electronics on the main board are damaged.
