I have a broken "START" switch on my KitchenAid SS Dishwasher and need help: 1. identifying which part or parts I need to replace, and 2. with how to remove the broken part(s) and replace it.

This evening I physically felt the "START" microswitch (covered by a waterproof exterior "label" of all the buttons functionality) fail in that it did not "pop back up" as it normally does / feel.

If possible to view on the attached photo the bad button is the second from the right. I suspect I may need what is described as the User Interface electronics with all the microswitches, but I do not see the label/cover anywhere.

Help would be appreciated!

Thanks, Ron
