Door looks really, really small?
There is an appliance dolly attached to the machine and they have a strap running across the door. It is a standard sized machine. I believe it is a (Patrician) KDP-20 Energy Saver V dishwasher. These were made around 1981-1984.
I remember these machines well and overall I like them. I especially loved the sleek control panels. There were 4 models in this series: Superba, Patrician, Imperial, and Custom. My cousin actually has this exact model but she has a trim kit front with a wood door to match her cabinets. I also have an aunt who has a KDC-20.
I hope someone will get this machine. I like the idea of heating the water to the correct washing temperature.
