Dishwasher Won't Finish Cycle

I have a 2 year old Whirlpool dishwasher that just started acting up. No matter what cycle we try, it never finishes the washing cycle. It just keeps running and running. I was going to order a new control board, but at a $170, I wanted to make sure it was the right thing to try. Any thoughts?

The first thing to try is to remove power from the unit for several minutes to see if it will reset.
