A dishwasher includes a tub at least partially forming a treating chamber, a dish rack provided within the wash chamber, and a spray manifold. The spray manifold can have multiple apertures and/or sprayers for emitting wash liquid to define a spray zone.

Dishwasher having spray manifold

A dishwasher having a tub defining a treating chamber, a dish rack, and a spray assembly associated with the dish rack. The spray assembly may include at least one sprayer positioned to spray treating liquid onto dishes received by the rack. The sprayer has two openings and may be movable between a first position and a second position.

Dishwasher rack spray assembly

A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage provided in the interior of the body, at least one upper outlet extending through the upper surface of the body and in fluid communication with the liquid passage, at least one lower outlet extending through the lower surface of the body and in fluid communication with the liquid passage, and a valve body moveable relative to the body to fluidly couple the at least one upper outlet and the at least one lower outlet to the liquid passage.

Dishwasher with sprayer

A dishwasher having a tub defining a wash chamber, dish racks located within the wash chamber, and pump assembly for recirculating wash liquid is further provided with a rotating spray arm located configured to direct a spray of liquid into the wash chamber to define a first wash zone and at least one nozzle configured to direct a spray of liquid into the wash chamber to define a second wash zone.

Dishwasher

A dishwasher for treating dishes includes a tub at least partially defining a treating chamber, a spraying system having a manifold with at least one sprayer for spraying wash liquid into the treating chamber, and a recirculation system for recirculating liquid sprayed in the treating chamber to the spraying system. The sprayer of the manifold has multiple apertures which are configured to emit liquid to different areas of the treating chamber.

A dishwasher has a treating chamber for receiving dishes for treatment according to an automatic cycle of operation and a dispensing system for storing and dispensing a treating chemistry to the treating chamber during the cycle of operation. The dishwasher may dispense a treating chemistry when a temperature of a liquid in the treating chamber satisfies a predetermined temperature threshold. The temperature of the liquid may be maintained to satisfy the predetermined temperature threshold for a predetermined period of time based on the treating chemistry.

Methods for dispensing a treating chemistry in a dishwasher

A dishwasher having a tub defining a treating chamber, a dish rack, and a spray assembly associated with the dish rack. The spray assembly may include at least one sprayer positioned to spray treating liquid onto dishes received by the rack. The sprayer has two openings and may be movable between a first position where the treating liquid flows through the first liquid opening into the treating chamber and does not flow through the second liquid opening and a second position where the treating liquid flows through the second liquid opening into the treating chamber. The sprayer may be rotatable between positions and may emit spray in both positions.

A household appliance, such as dishwasher, includes a bulk unit-dose dispenser configured to hold multiple unit doses of treating chemistry and dispense the treating chemistry at the appropriate time in a cycle of operation. The bulk unit-dose dispenser can include a multiple compartments moveable along a track, and the compartments can be sequentially moved into registry with a dispensing opening of the appliance.

Household appliance with bulk unit-dose dispenser

A dishwasher having a tub defining a wash chamber, a dish rack located within the wash chamber, and pump assembly for recirculating wash liquid is further provided with a spray assembly and a spray manifold with multiple nozzles each having at least one aperture emitting wash liquid into the wash chamber.

A dishwasher having a tub defining a wash chamber, and upper and lower dish racks located within the wash chamber. The dishwasher also has upper and lower rotating sprayers beneath the upper and lower dish racks, and a manifold with at least one nozzle having at least one aperture located in the wash chamber.

A dishwasher includes a tub at least partially defining a treating chamber for receiving utensils for treatment according to the automatic cycle of operation, a rotatable spray arm provided within the treating chamber and defining an interior through which liquid may pass, and hydraulic driving nozzles to rotate the rotatable spray arm in both a a first direction and a second direction, opposite the first direction.

Dishwasher with spray system

Methods of operating a dishwasher having a treating chamber, a sump fluidly coupled to the treating chamber, a sprayer for spraying liquid in the treating chamber, a recirculation pump fluidly coupled to the sump and the sprayer to recirculate the sprayed liquid from the sump to the sprayer, and a reuse tank for storing liquid. The methods remove and store liquid that do not include sedimented soil particles.

Methods of reusing liquid in a dishwasher

A dishwasher includes a tub at least partially forming a treating chamber, a dish rack provided within the wash chamber, and a spray manifold. The spray manifold can have multiple sprayers for emitting wash liquid to define a spray zone. A supply conduit supplies liquid to the manifold from a liquid source. A flow diverter proportionally divides that liquid supplied from the supply conduit to the sprayers in proportion to the volumetric flow rate requirement of the sprayers.
