Abstract

A rack detection system for a dishwasher, including: a docking system including a plug disposed on a rack, such as a lower rack, and configured to dock with a docking hole of a water supply tube on condition that the lower rack is in an operational position within the dishwasher; and a controller configured to sense a load on the pump motor of a pump for pumping water to the water supply tube and determine if the load on the pump motor is within predetermined operating limits. On condition that the lower rack is removed from the operational position within the dishwasher and the plug is not docked with the water supply tube such that water flows out of the docking hole, the controller is configured to sense that the load on the pump motor is outside the predetermined operating limits and shuts down the dishwasher.
