I have a Kenmore Elite that was bought three years ago. The unit will not complete the wash cycle. It is getting stuck in rinse mode and it never goes into the drying cycle. The dishwasher will run for hours just stuck there. ( I think that it is made by Bosch) model 630.16309406. I bought a new control panel and replaced it. This did not work. I am not sure what to look at next.

HELP!
