Kenmore Washer Error Code F51
Motor rotor position sensor fault
Common Causes
- 1Rotor position sensor failed
- 2Debris under the basket jamming the rotor
- 3Loose rotor bolt
- 4Wiring fault to the position sensor
Step-by-Step Troubleshooting
- 1
Unplug the washer and remove the rear panel to reach the direct-drive motor and rotor at the base of the outer tub
- 2
Check for a sock, coin, or bra wire wedged between the rotor and stator that stops the rotor turning freely
- 3
Confirm the center rotor bolt is torqued down, since a loose rotor lets the position sensor lose its reference
- 4
Inspect the rotor position sensor and its harness for a cracked sensor or a loose connector before replacing it
Pro Diagnostic Tip
F51 is specific to the 110-series direct-drive Kenmore, a Whirlpool build: the control cannot read the rotor position during agitation or spin. The single most common cause is a small item lodged between the rotor and stator, so clear that before ordering a sensor, and always re-torque the rotor bolt.
