3. Lift the outer tub up and disengage the
suspension rod assembly from the slot in each
corner of the outer tub.

4. Pull the outer tub assembly out of the washer
cabinet.
Caution: Care must to taken when installing and
sealing the drain hose to ensure there is no water
leakage.
Note: When installing, apply a thin coat of sealing
compound (part no. WH60X15) to the inner surface
of the drain hose.

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 power
changes frequency.
• The motor reverses rotational direction when
the power board reverses electrical polarity to
the motor.

The washer motor has an approximate resistance
value of 5 to 15  between any 2 of the 3 wires:
Blue to red - 5 to 15 
•
Red to yellow - 5 to 15 
•
Blue to yellow - 5 to 15 
•
Resistance can be measured at the yellow, 3-pin
connector on the power board or at the motor. (See
