TEST #3b: Drive System – Motor
This test checks the wiring to the motor and
the motor itself.
NOTE:
Drain water from tub and remove any
wash load items present in the basket.
1.
See Activating Service Diagnostic Mode,
page 2, and check the motor and electrical
connections by performing the Low, Mid, and
High Speed Spin Test under Service Load
Control Mode, page 4. The following steps
assume that this step failed.
2.
Unplug washer or disconnect power.
3.
Check to see if impeller will turn freely and
is not connected to the basket.
NOTE:
Rotating the impeller quickly can cause
the UI to attempt to power up, and may cause
audible feedback and the main control to power
up and apply braking torque to the impeller.
¾
If impeller turns freely, go to step 4.
¾
If impeller does not turn freely, determine
what is causing the mechanical friction or
lockup.
