I noticed that the water hasn't been draining from the bottom of my dishwasher, I cleaned the drain hole, hose, etc. I ran an empty cycle to see it that helped. That is when I noticed that it ran fine until it got to the rinse cycle, at that point the rinse water filled and the heater came on but the motor did not engage...no rinsing and no draining. The timer moved normally and then after the rinse cycle the dry cycle ran. Any ideas on why the motor would run during the wash and not the rinse?

Thank you
