Replaced Kitchenaid control panel and now not cleaning

 I replaced the control panel on my Kitchenaid dishwasher KUDS301XBL9. The original control panel was failed with 4 hour delay and cancel buttons dimly lit. The new control panel W10500172 operates normally, but now the machine won't clean. The dishwasher makes all the right noises. The dishwasher opens the detergent box, and there is water getting to the top rack, checked by putting an upturned bowl in the top rack. The water pumps out normally. I'm wondering if the fact that the dishwasher was off for two weeks before replacing the control panel could have let trash harden up at the pump.

I was right, a good cleaning with dishwasher cleaner at high temperature solved the problem. Moral is don't let a dishwasher sit for weeks to let trash on the internal garbage disposal filter dry out, causing a clog.
