GE Nautilus Dishwasher Review

We recently bought a new home with a GE Nautilus dishwasher installed. It has only been three weeks and I've done dishes several times with the machine. Every time I noticed this odor. Eventually, today, and thank goodness I was home, I smelled that odor across the house, upstairs, and two rooms down a hall. I followed the smell to the kitchen where I noticed smoke coming out of the dishwasher. I also noticed that toward the top near the lock mechanism it was melting and turning a yellowish-brown. I don't think that is normal. I immediately shut the noisy thing off (yes it is loud too, but right now that is the least of my concerns). The locking mechanism was EXTREMELY hot to the touch and had to pull my hand away. I am washing all my dishes by hand until we get this thing replaced. For the record, all my appliances are GE too, and I have NEVER had a problem with any of the other ones.
