Another one came up about 2 years ago now, over in Melbourne.
It seems these dishwashers were produced for the foreign market, as the member who picked it up (ian_p61) mentioned it had both hot and cold water inlets, as well as a maximum electrical load of 2400w (suggesting it could completely heat its own water, which was common for Australian machines then, and even now) when I discussed possibly grabbing it from him.*
The bigger dream for me would be to find a GE Potscrubber 2800. Our member Rapunzel (Olav) owned one of these for a period of time. From what I understand, the machines weren't marketed very much, and cost a fortune for the time. I imagine the KitchenAid offerings wouldn't have been much different, and were intended for a very niche market (The homes of the well-to-do Australians of the time).
*In the end, this didn't happen. The distance is much too far for it to be worth driving, or freighting the machine, in reality.
