Scott,

Sorry, don't have much to offer. Sounds as if it was working until you
did this cleaning. The touchpad seems to be out of stock at the web-sites I
checked.
I'd suggest cleaning the plug where the touchpad enters the control
board. I'd try re-cleaning the touchpad and while disassembled check the
switches with a DVM. If the touchpad is gone you'll need to hunt around to
find a replacement and it won't be cheap. Maybe time for a new dishwasher.
