What Does Error F51 Mean?

The Kenmore washing machine F51 error indicates a motor control unit issue, often linked to a faulty rotor position sensor (RPS). This error can cause the washer to display F51 on the control panel and may prevent the drum from spinning or completing cycles. Unusual sounds during operation may also be present, signaling potential obstructions or wiring problems affecting rotor movement.

Common Symptoms:

  • Washer displays F51 on control panel
  • Washer unable to spin or complete cycles properly
  • Drum fails to spin normally or stops mid‑cycle

Possible Causes

  • Faulty rotor position sensor (RPS) (medium)
  • Obstruction or mechanical resistance hindering drum rotation (medium)
  • Wiring/connectivity issues between RPS and control board (medium)

How to Fix Error F51

DIY Fix Basic checks and power reset

  1. Unplug the washer from power to ensure safety.
  2. Remove laundry and try to manually spin the drum to check for resistance or obstructions.
  3. Check accessible areas for small objects that could be blocking the drum or motor area.
  4. Restore power and attempt a cycle to see if the error returns.

Technician Only Inspect and replace rotor position sensor and related components

  1. Disconnect power and tilt the washer back to access the motor assembly.
  2. Inspect wiring harnesses from the rotor position sensor to the control board for damage or loose connections.
  3. Test the rotor position sensor and motor signals in diagnostic mode if supported by the washer model.
  4. Replace the rotor position sensor and any damaged wiring as needed.
  5. Confirm resolution by running a full diagnostic or wash cycle.

Parts needed: Rotor position sensor (RPS), Motor wiring harness

🛑 When to Call a Pro:
  • If basic checks do not clear the error and you are uncomfortable accessing internal motor areas.
  • If visual inspection reveals significant wiring or motor damage.
  • If diagnostic testing indicates control board communication or multiple subsystem failures.
