I only saw one Kaiser dishwasher, and that was at University Hospital, where I worked in 1985. It was upstairs from our office, on a floor that had been abandoned sometime in the 50's, and used only for storage while I was there. It was in a countertop, with a stainless steel sink. I wondered what it was, so oped it, and saw a rack. They didn't prepare food in that building, so it must have been used to clean medical supplies, before they were put into the autoclave.
