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 clutch assembly includes a drive shaft extending along an axial direction, and an output component, the output component defining a central opening in which the drive shaft is inserted. The clutch assembly further includes a clutch selectively coupling the output component to the drive shaft. The clutch includes a cavity defined in the output component and in communication with the central opening. The clutch further includes a bearing disposed within the cavity, the bearing movable within the cavity between a first position and a second position. The bearing is spaced from the drive shaft in the first position. The bearing contacts an inner surface of the output component defining the cavity and contacts the drive shaft to transfer rotational motion from the drive shaft to the output component in the second position.

A system and method for washing items with water, includes a water inlet and a container for receiving the items to be washed. The system comprises a water purification apparatus for purifying water introduced through said water inlet to produce purified water. The water purification apparatus comprises at least one filter for filtering off particulate solids, a reverse osmosis device, and at least one deionizing filter. The system further comprises a reservoir for storing purified water produced by the water purification apparatus, said reservoir being connected to said water purification apparatus and said container, so that the items are washable inside the container with the purified water.

A liquid recirculation system having a pump for recirculating liquid and a liquid filtering system for filtering the recirculating liquid. The liquid filtering system includes a filter disposed in the recirculation flow path to filter the liquid and a flow diverter or flow diverter to aid in cleaning the filter.

A system (10) for washing items (12) with water, comprising a water inlet (18) and a container (13) for receiving the items (12) to be washed. The system (10) comprises a water purification apparatus (19) for purifying water introduced through said water inlet (18) to produce purified water. The water purification apparatus (19) comprises at least one filter (25, 29, 30) for filtering off particulate solids, a reverse osmosis device (26), and at least one deionizing filter (27, 31). The system (10) further comprises a reservoir (20) for storing purified water produced by the water purification apparatus (19), said reservoir (20) being connected to said water purification apparatus (19) and said container (13), so that the items (12) are washable inside the container (11) with the purified water. Disclosed is also a method for washing items.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A dishwasher appliance includes a tub that defines a wash chamber for receipt of articles for washing. A sump is positioned at a bottom of the wash chamber for receiving fluid from the wash chamber. A fluid circulation assembly is at least partially disposed within the sump. The fluid circulation assembly is mounted in the sump with a resilient mounting post, whereby the fluid circulation assembly is vibrationally isolated from the sump.

A household appliance can include a tub at least partially defining a treating chamber for holding liquid with an access opening, a nozzle emitting liquid into the treating chamber, a recirculation circuit fluidly coupling the treating chamber to the nozzle. The recirculation circuit can include a recirculation pump and a filter having a housing with an inlet and an outlet, ferrite particles located within the housing, and a magnet having a first operational state and a second operational state.

A fluid pump volute offshoot system for debris diversion and collection, a solids collection system, and related methods, for a pot and pan, or other, similar, washing machine is provided.

A method of removing food soils from a recirculated washing solution includes adding a flocculating agent to the recirculated washing solution and separating the particulates from the recirculated washing solution using a hydrocyclone. The flocculating agent causes a portion of the food soils to combine into particulates having a higher density.
