Geez, guys, where's your sense of adventure? I thought this was a place for hackers to gather. Instead I see a bunch of old fuddy-duddys going "why ever would you want to do that?" or "don't touch that, it might be important!" Hang your heads in shame.
Dude, I know nothing of hacking dishwasher micro controllers, but I think you went to the wrong place. Maybe the AARP forums might have more adventurous souls.
