Judging by the tag and squinting a little, the dishwasher might be...drumroll...a General Electric.
Yep, apparently they made commercial dishwashers along with their GE/Hotpoint ranges, ovens, griddles and fryers. I have a few photos of GE equipment in my "Commercial Appliances" library on my PC, full of old equipment used in commercial kitchens and laundries. GE doesn't come to mind for commercial kitchen equipment. I'm not sure if GE designed/built their commercial dishwashers in-house or farmed it out to Vulcan/Autosan.
I did see an ancient Hotpoint deck oven in a grade school kitchen when I was on a call for their walk in. That was something I had swore I would never see, but there it was.
