Amana LWA40AW2 Washer -- The washer will not agitate in all Regular Cycles or Perm. Press Normal. It does agitate in Perm. Press Light & all Delicate Cycles.
The lid switch is working. Power supply is OK. When not functioning there are no sounds [e.g. humming, etc.]. When left in Regular Cycle [& not agitating] the timer advances. All attempts have been with only a few items of clothing [very light load].
I am puzzled since it functions in three of the possible seven agitation cycles. This, to me, eliminates motor, transmission, belt, lid switch, and power as possible causals. This leaves only the Timer/circuit board in the system but since it advances even though not functioning I am uncertain if it is the problem.
Suggestions will be appreciated.
