Rinse water heating delays
In the older KitchenAids that offer the option of a sani rinse, it was always the third rinse and only offered for years on the Superba, which is also the only model from the 15s through the 18s that had a heating element in the sump, except for the portables. The Custom and Imperial only had two rinses. The third rinse on the Superba models only filled with a gallon of water, which it heated in the sump, not while recirculating, and at 1400 watts so it took less time. In the period of recirculation after the heating, it did not really heat the load, especially in the top rack to sanitizing temperatures, but when your hot water supply is not very hot, this does improve drying. The heating element in the 18 Superba allowed it to offer the Soak & Scrub pot smasher cycle with alternate periods of recirculation and heating of the water. After the 15s, KA only offered the Soak cycle which was supposed to be used with an enzyme dishwasher product made especially for food soil that would be eaten by enzymes. Alas, it did not make it in the market back in the late 60s, So, owners of old KitchenAid dishwashers with soak cycles, your machines' day is here with the new enzyme products for the soak cycle. Starting with the 14 series, KitchenAid, like many other dishwasher manufacturers, offered a Utility and Utensil cycle or Pots and Pans cycle that was just a regular cycle with an abbreviated or skipped dry period to loosen soil but not allow it to dry before it was scrubbed off by hand.
