Why won't the drum agitate or spin...sometimes. Many details provided.
This is for a Kenmore Elite HE3 Front Loading washer.
My washer does not rotate the drum either in wash or spin modes. Washer fills, and drains through the cycles fine; just no drum rotation at all.
I have seen no error codes during or after washer cycle.
I have run the Diagnostics and it goes through C:00 through C:08. But at C:04, C:07 and C:08, the drum does nothing (it is supposed to rotate) during those steps.
The washer cycles completely through the diagnostic procedure without a failure code, but the drum does not rotate/agitate/spin.
It fills with cold and hot water and drains when it is supposed to, but no drum action.
I also cleaned the filter trap for good measure. It had only a little debris; not clogged at all.
I checked the resistance of the motor across pins 1-2, 1-3 & 2-3 and results were 6.x ohms.
I disconnected and reconnected all connections to the motor and motor control units.
The motor control unit and motor have no visible signs of distress.
Drum turns freely by hand. Belt is fine. Door switch is fine. There is no transmission, only the motor.
When I start the washer, I can gently turn the drum flywheel after the door locks and it will start turning by itself and the washer cycle will finish the washing cycle complete.
Less often, when I start the washer, the drum will turn normally and and complete the washer cycle.
Any suggestions as to what my problem could be with the washer? I would like to rule out motor, the motor control board or other component before buying an expensive replacement part.
Thanks for the assistance!
