A spray assembly may include a water supply conduit, a main spray arm, and a satellite spray arm. The main spray arm may be rotatably coupled to the water supply conduit to rotate about a first axis, and a satellite spray arm may be rotatably coupled to the main spray arm to rotate about a second axis. The satellite may define at least one nozzle and at least one fluid channel extending from the second axis to the at least one nozzle. The at least one fluid channel of the satellite spray arm may define an arcuate shape having a portion proximate the second axis disposed at a first distance relative to the base parallel to the second axis, and the at least one nozzle being disposed a second distance relative to the base parallel to the second axis. The second distance may be shorter than the first distance.

A dishwasher includes a pump device operated by a pump current for supply of washing liquor to a first spray device via a first hydraulic arrangement for providing a first washing zone and to a second spray device via a second hydraulic arrangement for providing a second washing zone. A third spray device is connected to one of the first and second hydraulic arrangements for providing an intensive washing zone. In a first switching state, the third spray device is isolated from the one hydraulic arrangement, and in a second switching state the third spray device is connected to the one hydraulic arrangement. A control device determines a current switching state of the third spray device as a function of a difference between the pump current when washing liquor is supplied to the first hydraulic arrangement and when washing liquor is supplied to the second hydraulic arrangement.

A dishwasher and method for operating the same utilize a diverter valve to control via rotation the flow of fluid such as wash fluid or pressurized air to a rotatable conduit supported in the rack of a dishwasher. A valve member may be disposed at a predetermined rotational position about an axis of rotation of the conduit such that a fluid inlet on a rotatable valve body may be rotated to the predetermined rotational position to restrict fluid flow to the conduit.

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 dishwasher for treating dishes according to a cycle of operation includes a tub at least partially defining a treating chamber, a manifold, a rotatable sprayer that is rotatable about a rotation axis and has an inlet and multiple nozzles collectively forming an outlet and a bushing creating a sealing interface between the manifold and the rotatable sprayer.

A dishwasher with a tub that at least partially defines a treating chamber with an access opening, a closure moveable relative to the tub to selectively open and close the access opening, a lower dish holder located within the treating chamber, a middle dish holder located within the treating chamber above the lower dish holder, and an upper dish holder located within the treating chamber above the middle dish holder and having container supports defining a support surface.

A household dishwasher includes a dishwasher cavity and a spray facility arranged within the dishwasher cavity for spraying washing liquor and/or fresh water in the dishwasher cavity. The spray facility includes a nozzle for spraying the washing liquor and/or the fresh water and a spiral-shaped flow-conducting element for feeding the washing liquor and/or the fresh water to the nozzle. The spiral-shaped flow-conducting element is configured, during operation of the spray facility, to feed the washing liquor and/or the fresh water to the nozzle in such a way that the washing liquor and/or the fresh water exits the nozzle as a rotating conical spray jet.

A dishwashing appliance or variable spray assembly, as provided herein, may include a manifold body, a diverter valve, and a driver. The manifold body may define a fluid inlet, a first flow path, a second flow path, a first spray outlet, and a second spray outlet. The first and second flow paths may be downstream from the fluid inlet. The second flow path may be in fluid parallel to the first flow path. The second spray outlet may be spaced apart from the first spray outlet. The diverter valve may be mounted within manifold body and movable between a first zone position directing wash fluid to the first flow path and a second zone position directing wash fluid to the second flow path. The driver may be disposed outside of the manifold body to motivate the diverter valve between the first zone position and the second zone position.

A dish rack for use in a dishwasher is provided. The dishwasher includes a tub defining a washing chamber for cleaning kitchenware and the like. The dish rack includes a wall bounding a space. A dispenser unit is mounted to the dish rack and is configured to hold an additive. A hydraulic circuit is disposed within the walls of the dish rack and is placed in fluid communication with the dispenser. Fluid pressure from the hydraulic circuit is operable to eject the additive from the dispenser unit into the washing chamber.

A dishwasher with a tub that at least partially defines a treating chamber with an access opening, a closure moveable relative to the tub to selectively open and close the access opening, a lower dish holder located within the treating chamber, a middle dish holder located within the treating chamber above the lower dish holder, and an upper dish holder located within the treating chamber above the middle dish holder and having container supports defining a support surface.
