GE Dishwasher CDT828P2VS1 — Control Pads Activating Randomly but Don't Respond to Touch

[lothian.mcadam]

GE Café Dishwasher
CDT828P2VS1

Problem:
The control pad along the top of the door suddenly no longer registers pad presses.

Instead, it displays random presses; meaning, the indicator light beneath a given selection illuminated (along with corresponding "beep"), then goes out, followed by the apparent activation of some other pad. There is no pattern. No pad responds to touch.

I find only two t'shooting recommendations—neither had any effect:
 1) Thoroughly clean and dry the control surface, and;
 2) "Reset" the appliance by cutting power to it for [insert length of time here], then power back on.

The dishwasher worked yesterday; today it behaves as described, and the dishwasher is unusable.

Thoughts? Suggestions? Anecdotes-of-an-identical-experience-and-instructions-on-how-to-fix-it..?
