I was asked to provide an update. We did not pay a technician $300 to solve this problem for us.
We ordered a new control panel from the Kenmore parts site and intalled it ourselves. Cost: $116 (part and shipping) plus our labor. The dishwasher works fine and will probably last another 2 years until the replacement control panel breaks.
By then we will be in a position to buy a Bosch. Recommend do not purchase a Kenmore Ultra Wash, or any Kenmore with similar push-button controls.

I bought a Kenmore Ultra Wash dishwasher from Sears in 2011. The model is 665.13742K603.
After two years the buttons have quit working. I read on multiple sites that the problem is a poor-quality control panel. I recommend avoid this model. It cleans well but not if it won't start.
I'm sorry I also bought a washer, dryer, fridge and range from Sears as I'm worried how long they are going to last.
My 'maintenance agreement' is this: If you sell me a bad product, I will tell all my friends and I will never buy from you again. This agreement is free of charge.
Monetary Loss: $300.
