Hall Sensor
• The Hall effect sensor measures the motor rpm.
• Four wires connect the Hall sensor to the power
board at the 6-pin dark blue connector. (See
Circuit Board Connector Locator View
.
)
• If the sensor has failed, the motor will not
operate.
• The Hall sensor clips onto the frame of the
stator, and can be replaced separately.

To remove the rotor and stator:
WARNING
: The rotor is not grounded. Unplug the
washer before servicing to avoid electrical shock.
1. To access the motor, the washer must be placed
on its side. Place a towel or blanket on the
fl
oor to prevent scratches to the surface of the
washer.
2. Remove the 24-mm (15/16-in. SAE equivalent)
rotor nut with a socket or adjustable Crescent
wrench (rotate rotor nut counterclockwise to
remove). Remove the
fl
at washer.
Note
:
Use a rubber mallet if needed to tap the
wrench to break the nut free.
