Dishwasher buttons not responding

The buttons on my Kitchen Aid KUDS30IXSS2 stopped responding. One or two buttons light up as if they have a little power, but all the buttons are unresponsive. I have tried resetting the power with no response. In doing an Internet search, some say to replace the fuse and some the whole panel. I can’t find any instructions on how to do this, or if either of these is actually the problem. Please help.
