Motor Assembly
• The washer has a direct drive pulse width
modulation motor that does not utilize a belt,
transmission, or mechanical brake.
• The motor assembly is composed of a coil
wound stator, Hall sensor, and permanent
magnet rotor.
• The motor varies speed and torque when the
pulse width modulated voltage from the
inverter changes frequency.
• The motor reverses rotational direction when
the inverter reverses electrical polarity to the
motor.
The washer motor has an approximate resistance
value of 8 Ω between any two of the three wires:
• Blue to red - 8 Ω
• Red to yellow - 8 Ω
• Blue to yellow - 8 Ω
Resistance can be measured at the yellow, 3-pin
connector on the inverter board or at the motor.

Inverter and Main Board Pin Connectors.)

4. Pull the outer tub assembly out of the washer
cabinet.
Caution: Care must to taken when reinstalling
and sealing the drain hoses to the outer tub to
ensure there is no water leakage.
Disengage
3. Lift the outer tub up and disengage the
suspension rod assemblies from each corner
of the outer tub.
