Steve, you're absolutely correct on your cycle observation. when I moved here 22 years ago, friends of mine that moved here with me, bought a house that was around 1978 or 1979 built and had an avocado kitchen with the 2-oven self-clean hotpoint range, a Philco fridge, and this exact dishwasheer. I got to play with this dishwawsheer several times, particularly when they were on vacation & I'd go use their secluded hot tub. IIRC, the first thing it did on all 3 cycles was like a suds kill or purge--the water line opened up while the drain solenoid was still open to flush out the hot water line. And yes S'n'S and Normal cycle sequences were solely determined by which button was pushed. And no, no wwater heat maintenance during soak periods like on the Superbas. Otherwise, it circulated, soaked, circulated, soaked, ... The dry cycle was shorter on S'n'S because the rinses went further into the "dry" portion on the knob. Unfortunately the house was out of my price range when I moved here--I wish I had seen it first though. I'd have bought it solely for the kitchen and hot tub. It was a 4-bedroom house.
