Dishwasher touch panel or control board?

Dishwasher touchpad operates inconsistently. At times, it will work perfectly. Other times some of the touch pad keys are dead. For example, when trying to set a timed delay start, the keys are not functional, but I can start a normal cycle immediately.

At times, even normal cycle immediate start key will not function and will only start on heavy cycle.

I am assuming that the likely problem is the touch pad/console (part # AP3044891 in black) and not the electic control panel (part # AP3044855).

Would appreciate any advice from Gene or others.

Thanks in advance. Mike

Thanks! Much appreciated.
