Thanks for the info Gilles!
Well it's finally in Brooklyn. What a drive. Going was a piece a cake, but oh coming back on I-95 was brutal. When I got there, the KA was still installed. But the seller got it out and it wasn't easy. There was no hot water hose connected to the dishwasher, it was a copper pipe. I had never seen someone do that kind on installation. It also meant it hasn't been moved since installed. Underneath was pristine, clean as a whistle. In fact, I was amazed how clean it was on the sides and top. The insulation looked perfect. There was some mold and light grime in the tub, but it, and the racks looked great. I didn't see any rust first hand, except a light rust spot on the filter. According to the seller, it was his parents machine. It was used twice a week, six months of the year since new. It was last used 2 years ago. I'll be posting pictures soon.
