HS — Wash Motor Hall Sensor Error
HS indicates a Hall sensor error in the wash (circulation) motor — the control is not getting a valid speed/position signal from the motor. Check the motor-to-control wiring; the wash motor or control board may need replacement. It is not a high-limit/in-tub temperature sensor fault.

How to fix it
- Cut power at the breaker.
- Pull the dishwasher and remove the bottom access panel to reach the circulation motor.
- Inspect the motor's wiring harness and connector for looseness, corrosion, or damage, and reseat or repair as needed.
- With power restored, run a cycle and listen/watch for the motor spinning up during the wash step (a spin test).
- If the motor does not spin or the Hall sensor signal is still absent after wiring checks out, replace the circulation motor assembly.
Why it happens
Typical signs: HS shown after fill · Cycle aborts before heat-up · Cold or lukewarm wash water · Heated dry not working
- Failed motor speed/Hall sensor The Hall sensor built into the circulation motor is not reporting a valid speed/position signal to the control.
- Damaged or disconnected motor wiring The harness between the circulation motor and the main control can work loose, corrode, or get pinched during service.
- Failed circulation motor If the sensor signal and wiring both test good, the wash/circulation motor itself has likely failed.
