Long story short, whoever assembled my dishwasher at the factory tightened one of the screws on the inside door panel too tight and the plastic mount in the top right broke off. Of course I didn't know about this until last week when the buttons on my dishwasher panel stopped working completely.

Taking it apart, I noticed that screw was just spinning in place when I tried to loosen it. Once I got all the other screws out, I found the broken mount. So because of this, moisture has been seeping into the control board and panel area.

The board *looks* OK as far as I can tell with my computer experience, but I'm not a doctor I just play one on TV. Anyways, the ribbon cable for the control panel on the top of the door had obviously been corroded and was very visible to figure that one out.

So I ordered the new panel from APP (thankfully you guys had it) and installed it today. The cycle buttons work (Auto Clean, Heavy, Normal and Light wash) and the Hi-Temp Wash button is lit, but the Touch Scrub and Heat Dry buttons don't work, which they did prior to the thing breaking last week. As far as I can tell I have all the connections right, but any advice? Maybe I have to run it through a normal cycle first to reset the whole thing? No idea, please advise!

Awesome! Thanks for the information. I would hope that since it's a new part shipped from APP the cable wouldn't be damaged, but I'll check it to make sure. I didn't clean out the control board connecter, though I probably should have at least inspected it. I'll take it all apart again after work and see what I can find out.

Also, is there a better way to protect the cable itself in case moisture does find it's way in there? I could visibly see rust (or some sort of corrosion/discoloration) on the old cable. I thought it was encased in plastic but maybe not. I guess if the old one lasted five years it should be fine for another five or more years since there is no longer a loose screw on the inside panel, I just like being thorough.

Thanks for the help. I ended up taking it back apart and redoing everything again. This time I made sure the buttons were working before I got it all back together. All buttons and modes are now working. Thanks for the help!
