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.
To check the motor:
1. Remove the service panel. (See
Service Panel
.)
2. Disconnect the motor wire harness.
On the motor plug, check for an approximate
resistance value of 6
Ω between any two of the
three wires:
• Blue to white – 6

• Blue to red – 6

• White to red – 6

The sensor has a resistance value of approximately
114

between the two yellow wires (tacho
generator).
Operation of the motor assembly can be checked
by using service test modes t04, t13, and t14. (See
Service Test Mode
.)
Speci fi c failures associated with the motor assembly
can initiate error codes E15, E16, and E18 thru E21.
(See
Error Codes .)
