A washing appliance such as a dishwasher or laundry washing machine comprises an ion-exchange water softening section and a brine generator to supply brine to the water softening section to regenerate ion-exchange resins therein, and a valve (such as a float valve) in a water supply conduit to the brine generator. The valve permits water to flow into the brine generator but blocks back-flow of liquid from the brine generator to the water supply conduit.

A single cavity dishwashing appliance with one or more drawers is disclosed. The drawer may be moveable between a closed position and an open position. A drip shield may be provided to prevent washing fluid from dripping onto the floor or onto the inner components of the dishwashing appliance when the drawer is in the open position.

A method for controlling a dishwasher includes: supplying washing water to a sump; rotating an impeller disposed in a washing pump by a washing motor so that the washing water flows into the washing pump from the sump; operating a heater disposed in the washing pump so as to heat the washing water existing in the washing pump and generate steam to supply to a steam nozzle; and supplying the washing water or steam in the washing pump to the steam nozzle by rotating the impeller at a second set rotational speed lower than a first set rotational speed by the washing motor. The method further includes closing a selector valve, configured to open and close a path between the washing pump and the steam nozzle, when the impeller rotates at the first set rotational speed or higher.

A retracting rack for an appliance such as a dish washing appliance. The rack may be positionable between a stowed position and a deployed position. A spring may drive the rack towards the stowed position. A locking mechanism may be used to secure the rack in one or more positions.

A dishwasher comprises an internal reservoir for rinse-aid or other wash or rinse additive, a door associated with a refill port to the rinse-aid reservoir, and a flexible conduit between the refill port and the rinse-aid reservoir. The door associated with the refill port to the rinse-aid reservoir may also carry or enable access to a detergent compartment.

A dishwasher can include a chassis, a tub, and a dishrack moveable into and out of the tub. A rail assembly mounting the dishrack to the tub can include a slidable rail and at least one support housing secured to the tub for supporting the slidable rail. The dishwasher can also include at least one light source for illuminating a portion of the tub.

A dishwasher for treating dishes according to a cycle of operation, the dishwasher comprising a tub at least partially defining a treating chamber, a dish rack received within the treating chamber and configured for receiving dishes for treatment during the cycle of operation, a sprayer located within the treating chamber and above the dish rack, and emitting a liquid onto the dish rack to form a high-speed spray.

A single cavity dishwashing appliance with one or more drawers is disclosed. The drawer may be moveable between a closed position and an open position. A drip shield may be provided to prevent washing fluid from dripping onto the floor or onto the inner components of the dishwashing appliance when the drawer is in the open position.
