Whirlpool dishwasher: can't set program and just says "Out"
Possible (probable in my limited experience) problem : the wires are corroded.

Take off the panel and inspect the cable (likely green with flat copper strands). If it's corroded, gently clean it with a magic eraser, or harsher methods if necessary.  Then coat it with liquid electrical tape.  Finally, inspect the seal around the door - it can be knocked off-kilter pretty easily, and just needs to be set back in place.

As I said my exp is limited, but with my dishwasher and range microwave, this has been the problem when display was snafu'ed.

If a noticeable amount of steam leaked from the top of your dishwasher in recent months, this is almost definitely the problem.

There should be some videos on how to remove the panel if you want a step by step.  Good luck!
