Your Kenmore dishwasher was manufactured by Whirlpool for Sears.
This is a common problems that I see often. Nothing you can do except replace the touchpad/control panel.
Your model dishwasher uses Touchpad/Control Panel Part # 8542350
I have attached a copy of the tech sheet for your dishwasher. I have not had time to look at the tech sheet, but it has a troubleshooting guide and it probably tell you how to test the buttons on the control panel with a multimeter. Without the buttons working correctly you won't be able to run the diagnostic test in the tech sheet.
Let us know what you decided to do or if you have any other questions.
Hope that helps, thanks.
