Motor speed sensing error

Unplug the washer and access the motor at the bottom of the unit
Locate the rotor position sensor (RPS) on the stator and check its connector
Measure RPS resistance — expect 10,000-15,000 ohms between the two terminals
Spin the rotor by hand while observing the multimeter — resistance should fluctuate smoothly
If RPS tests good, check the motor control board for signal processing faults
Pro Diagnostic Tip
Always test the RPS first — it fails 3x more often than the motor on the KitchenAid direct-drive platform. The RPS is a $25 part vs $200+ for the motor. On the KFWB stator, check for hairline magnet fractures on the rotor ring caused by thermal stress.
