Washer motor control unit / inverter board

Direct-drive and inverter washers use a motor control unit (MCU) that powers a 3-phase motor and reads a hall sensor or tach. Separate MCU, motor windings, hall sensor and harness before buying a board.

Hall sensor and tach generator (motor speed feedback)

Hall sensors are 3-wire devices (supply, ground, signal) that switch as magnets pass; tach generators are 2-wire coils that make a small AC voltage as the motor turns. Test the right way for the type.

Rotor position sensor (direct-drive motors)

On direct-drive motors the rotor position sensor sits on the stator and tells the inverter where the rotor magnets are. A bad sensor, cracked connector or water ingress gives motor errors even with good windings.
