GE Profile dishwasher emitting constant beeping noise

My power went out this morning for ~30 min and, when it came back on, the dishwasher started emitting a constant beep. None of the display lights or buttons appear to be working. I flipped the fuse to stop the electricity from running to the dishwasher to stop the beep (and keep me sane).

I found another post that seems to indicate maybe something is wrong with the Escutcheon? It just seems odd to me that something like this would break with a power outage.

Any advice?
