My favorite dishwasher, next to the Sears Best Lady Kenmore roto-rack d/w that one neighbor had, was an avocado Kelvinator, that another neighbor had that I helped her buy at a place called HOT & COLD...
(Along w/ an avocado Custom Crafted Hotpoint Side X Side Refrigerator, an avocado Tappan self-cleaning electric range (of which the backguard light had two incandescent bulbs & the control knobs were on top of the back-guard w/ little "windows" below them) and a white Whirlpool washer & dryer set; yes helped buy all those appliances at the tender age of 7-yrs.-old!)
It was a free-standing dishwasher, which may have been "plumbed in", much like the other neighbors Lady Kenmore was & my friend's narrow Kenmore & even my other friend's Norge--Heck, I think just about everyone on the block had portable dishwashers w/ built-in installation, other than the few who had "true" built-ins, or us who moved our d/w's to & from the sink until they broke!!!! And there were other neighbors who have a very basic 1950's Kitchen Aid portable which I've never seen in use at all...
Then, there was also friend of the family that owned the Lady K d/w that had the same Kelvy in almond, which I saw built-in years later at his place!
This Kelvinator dishwasher had, I think 8 push-buttons, ranging from A to H, and the controls looked much like it was copying a General Electric or Hotpoint design...
