Nate, some friends here used to have a mid to late 80s belt drive (I let it go when the got rid of it cuz the belt broke). It used to do the water quick add inadvertantly thing off & on too. Now in your case, I THINK this is one of the "tags that prettty much doesn't have a timed fill, but a pressure-switch determined water fulfillment design. Maytag used to have in their literature the dishwasher worked regardless of water pressure. That also may have something to do with water needing to be added once all the sloshing and stuff got going.
