A method and dishwasher utilize a spray basket that includes a container body that defines a compartment for retaining utensils as well as multiple sets of nozzles, a portion of which are configured to direct a spray of fluid into the compartment, and another portion of which are configured to direct a spray of fluid external from the container body. The spray of fluid directed external from the container body may be used, for example, to provide a power wash zone adjacent to the spray basket to assist in cleaning other utensils in a dishwasher.

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.

A dual tine system includes a gear hub including a hub body, right teeth and left teeth, a right gear tooth device mounted to the hub body to rotate the right gear tooth device relative to the gear hub, a left gear tooth device mounted to the hub body to rotate the left gear tooth device relative to the gear hub, a right tine arm, right tines, a left tine arm, and left tines. The right gear tooth device includes a right gear tooth body and a right gear tooth extending from the right gear tooth body to fit within a right valley defined between a pair of the right teeth. The left gear tooth device includes a left gear tooth body and a left gear tooth extending from the left gear tooth body to fit within a left valley defined between a pair of the left teeth.

A dishwasher utilizes multiple rack-mounted corner sprayers disposed in corners defined between a side wall and front and rear walls of a dishwasher rack to direct fluid inwardly from the corners to wash utensils supported by the rack. The corner sprayers are in fluid communication with one another by a fluid channel that extends along the side wall of the rack, and an inlet port coupled to the first corner sprayer conveys fluid to each of the corner sprayers.

A dishwasher for treating dishes according to an automatic cycle of operation can include a tub at least partially defining a treating chamber receiving dishes for treatment and a spray system providing treating liquid to the treating chamber. A dish rack is located in the tub and has a bottom wall and at least a side wall extending upwardly from the bottom wall. A depending portion extends downwardly from the bottom wall and is oriented at an angle to the bottom wall to define an incline angle. At least one spray tube is carried by the dish rack.

A dishwasher and method for operating the same utilize a rack-mounted rotatable conduit incorporating a keyed connector disposed at an end thereof and configured to mate with a rotatable docking port disposed on a wall of a wash tub at a predetermined angular relationship when the rack is in the washing position such that rotation of the rotatable docking port causes rotation of the rotatable conduit.

A dishwasher and method for operating the same utilize a check valve in a rotatable docking port to control the flow of fluid such as wash fluid or pressurized air to a rotatable conduit supported in the rack of a dishwasher.

Provided herein are a spray arm assembly and associated dishwasher. The spray arm assembly may include a spray arm and a satellite arm. The spray arm may have a body defining an inlet opening and an outlet opening spaced along the body, and the body may receive washing fluid at the inlet opening and direct at least a portion of the washing fluid to an outlet opening. The body may further define one or more fluid supply channels extending between and fluidly communicating the inlet opening and the outlet opening. The satellite arm may be rotatably coupled to the spray arm at the outlet opening, and a portion of the one or more fluid supply channels may extend past the outlet opening to direct at least a portion of the washing fluid past the outlet opening and back towards the inlet opening before entering the outlet opening.

A dishwasher includes a tub, a first dish rack, and a second dish rack disposed above the first dish rack in the tub. The second dish rack includes a frame configured to couple to and adjust in a vertical position relative to a plurality of mounting rails in the tub. The second dish rack also includes a collapsible portion coupled to the frame and configured to adjust in a vertical position relative to the frame. In some embodiments, the second dish rack further includes a feed pipe coupled to the collapsible portion, the feed pipe having at least one connection point configured to align with at least one water supply point, wherein each vertical position of the collapsible portion corresponds to a different alignment of the at least one connection point and the at least one water supply point.

A dishwasher for treating dishes according to an automatic cycle of operation can include a tub at least partially defining a treating chamber receiving dishes for treatment, a spray system providing treating liquid to the treating chamber, a low profile dish rack located in the tub and having a bottom wall and at least a side wall extending upwardly from the bottom wall, with a depending portion extending downwardly from the bottom wall and oriented at an angle to the bottom wall to define an incline angle, and at least one spray tube carried by the dish rack and located below the bottom wall, the spray tube having nozzles emitting spray into the depending portion.
