Once you remove the escutcheon, you will see if it was a failed board or not. In many cases, the board failed due to a stuck solenoid on the right side of the dispenser. In this case, it melts the bracket and lots of other parts need to be replaced. Only a visual inspection behind the escutcheon will tell. Just remove the drip tray and take out the 2 screws underneath.
I usually go to the bottom hinge and unplug the harness to keep from getting the shizzle knocked out of me playing with the dispenser, or you can just unplug the whole thing.
