Motor Assembly
The motor assembly consists of a reversible,
variable speed, 3-phase induction DC motor, and
sensor. The motor drives the tub drive pulley with
a 7-rib belt. The sensor monitors motor rpm and
is connected to the control board. The motor
assembly is checked from the front of the washer
and removed from the rear.
There are 2 methods to check the motor assembly.
Method A:
Remove the service panel. (See
1.
Service Panel
.)
Disconnect the motor wire harness.
2.
On the motor plug, check for an approximate
resistance value of 6 ohms
between any two of the
three wires:
Blue to white - 6
•
Ω
Blue to red - 6
•
Ω
White to red - 6
•
Ω
The sensor has a resistance value of
•
approximately 118
Ω
between the two orange
wires.
Operation of the motor assembly can be checked
by using service test modes t04, t13, and t14. (See
Service Test Mode
.)
Specifi c failures associated with the motor assembly
can initiate error codes E3, and E15 through E25.
(See Service Test Mode.)
Method B:
Remove the service panel. (See
1.
Service Panel
.)
Remove the single Phillips-head screw that
2.
holds the right front leg of the inverter to the
base pan.
Slide the inverter rearward to clear the guides
3.
that hold the rear of the inverter to the base
pan.
Position the inverter to access the inverter

board.
Wash Basket Pulley
To remove the wash basket pulley:
Remove the belt. (See
1.
Belt
.)
Remove the 24-mm drive nut that holds the tub
2.
drive pulley to the wash basket. Remove the
pulley.
Caution: The nylon locking material used inside
the drive nut will be damaged upon removal. Use
replacement drive nut (Part # WH02X10211) when
reinstalling the tub drive pulley. Use a torque
wrench to tighten the 24-mm hex nut to 44-ft. lbs of
torque.
