I recall 40-ish years ago when relatives were visiting for Thanksgiving or Christmas or some such holiday after we'd gotten the KDI-17a. We loaded it up after the meal, packed to the brim as typical, and used the Soak cycle. My mother's aunt sat watching it warily, and remarked "I guess it has to fill" when it stopped spraying for the soak period ... I suppose envisioning that the tub filled like a washing machine and the dishes then whirled and sloshed around.
