The touch pad is not working on my Maytag dishwasher. The unit is less than 3 years old. I thought the problem was the control board so I replaced it. This did not solve the problem. The touch pad still is not working. Is the problem the touch pad itself of some other component?

I went through 4 control panels in 1 year. The last bad one they didn't take and left it behind. I noticed I could peel the top of the panel back from the right top corner exposing the contacts for the pause and the on buttons. Both had a milky tarnish from obvious water contact even though the panel was a couple months old. What quality control and engineering that is! Any way you can wipe clean with a contact cleaner, try and seal the corners with some rtv to prevent future water contact.
