Product review (5 stars): The control panel works great which is the expected outcome anyways
The control panel works great which is the expected outcome anyways. But this review is to help others diagnose and fix their dishwashers vs having to go through sears service which is very expensive.

The issue started with the smart wash button not working and over a period of months expanded to other buttons. After about 3 months the only function working on my dishwasher was normal wash. Eventually all the buttons on the control panel stopped responding and the control panel went completely dark. None of the lights would come on, including start or cancel. Replacing the control panel did the trick, the dishwasher now works like new.

It is a quick 20 min job to replace the panel assuming you have DIY skills and an understanding of how electricity and cabling works.
