I didn't agree with KA stand still water heating at the
Peter, that sequence was unique only to Superba type models--the pause, heat, then circulate. And this puase was a thermostatically controlled pause. I believe the 20 or 21 series lower models also paused for water heating, but it wasn't thermostatically held. All the other models in the KA from the WP prdouced 21-23 series line just heated the water while water was being circulated. I only remember Superba model advertising mentioning something about assured temp water heating. And as far as I was concerned, anything but a Superba was a comedown and compromise in KA line. That pause/heat sequence was many of the reassons why I WOULDN'T have a KitchenAid dishwasher, especially when I bought my GE GSD1200 in 1987. I knew that's why GE did such a superior job cleaning because it kept circulating those powerful jets of water. I think they would have been able to handle far heavier soil if they'd continued circulating wter while pausing to heat. Tomturbomatic has made similar comments about water cirulation and heating. Andrew in Orlando had similar comments about his KDS21 (I think that model series), plus the main wash phase wasn't as long as on the 22 he thought. And John lefever (combo52) also states the same as to why a WP PowerClean will clean far better than a KA. If you still have something with dirt on it in one of those after useing the PowerScrub cycle (thermostatic heat hold for Prewash (which could last for 30 to 45 minutes) plus the main wash heat and final rinse, then you needed it to be atomically blasted off the surface of what was dirty. It was a similar reasson why I didn't chose a Maytag reverserack in 1987, because their Sani-Scrub option merely turned on the heater throughout the circulation periods, but never a thermostatically held point in the cycle. And their TOL machine only paused for the heat for the SaniRinse--final rinse. A perfect KA would have been something like an 18 series with thermostatically held heat pauses while circulating during the main wash and final rinse. On the Superba Soak'n'Scrub cycles, the heater continued to heat the waterr during the "soak" periods, which improved results over the Imperiod model, which didn't continue to heat the water why paused (Gansky told me that). I also felt it was kinda stupid to have those pause periods during the S'n'S cycle--heavy soil expected should have always had water circulating.
