I have a Whirlpool direct drive unit that fills just fine, but once filled, it sounds like the motor kicks in for the wash cycle, yet the agitator/tub does nothing. When it goes to rinse, it pumps out without a problem, but it never goes into spin cycle.

I thought the coupler had failed, but it was intact. I replaced it anyway, since I had the machine torn down and the part in hand.

So, since nothing has changed in this repair, I'm looking for the next possibility. Suggestions??
