I have had the same problem, fixed the pipe and then had the display problem you described.
I turned off the dishwasher , held in all three buttons on the door and turned the power back on.
the unit kicked into life but showed 18 on both displays which counted down to 10 whilst doing a short cycle of some sort.
the display is stuck on ten with no other activity.
very confused and angry
