GE Spacemaker Won't Spin/Agitate/Drain

Hi all,

My GE Spacemaker WSM2420D3WW stackable fills to the correct selected level, but won't spin/agitate/drain or anything else. There are no motor sounds or other clicking when I try to start in the spin cycle. I had this issue previously, waiting a bit and playing around with the dial seemed to fix it that time. I've tried cycling the power and removing water from the unit.

Any Ideas?

Thanks,
Joe
