guess everything old is new again at some point
Tim, not really. There's not much you can do with a dishwasher interior arrangement. This has always been pretty standard since the mid to late 19600s. Exceptions were KitchenAid and GE/Hotpoint. Steve, as far as this being after the "roto-rack" style, no they were simultaneous or in tandem. Sears, and to a small extent Gaffers & Sattler, were the only D&M labeled brands with the roto-rack. Everyone else had slight variations of a top rack such as this. And Peter, as far as I can figure out, the most 2 right buttons were something like a hygenic single wash (the left of those two right buttons has a letter C aove it). The farthest right button, if anything like neighbors and friends with a comparable Magic Chef--Matic Chef called it total Magic Wash (and was red button instead of white) had heated delays in the main wash & final rinse. It could have also did a heat delay in the first pre-wash too. I cannot quite make out all the potential lettering on that farthest right button, but it looks like it could be Hygienic Combine Wash or Hygienic Complete Wash and I bet it had Letter A over it. From left to right, the buttons had starting points of A, A, A, B, C, and most likely A.
