UGH, awful machines. They ate themselves up with the damn water heating; vinyl racks, porcelain, everything eaten up with the hot water. They tended to die young and the miserable sales that resulted from the great customer dissatisfaction makes these pretty rare machines today. Many people found that it was better to just cancel the cycle after the last rinse, open the door and let the dishes flash dry because they dried better and you could shorten the cycle so that you could get another started if you were doing a lot of cooking, baking or were cleaning up after a big holiday meal. They sure as hell went back to the option of heated drying in the 20 series. KitchenAid owners replacing an older machine who were used to faster cycles and new buyers who knew of KA's reputation for good drying raised hell about the cycles and drying in this machine. The way they delayed the cycle for heating meant that by the time it filled for the last rinse, the water in the pipes was warm at best and completely cold if the pipes ran through a cement slab. I believe that it was with the 19 or 20 that KA eliminated the constant rinse overhead spray and it was missing for many years resulting in bits of stuff left on things in the corners of the top rack unless dishes were rinsed before loading. The only good thing about the 19 series is that it introduced the full width wash arm under the top rack. The run of the 18 series, every bit as radical a redesign as the 15 and featuring my favorite Superba, was shortened by KA's push to introduce a more energy efficient machine, but the public was not impressed by the 19.
