The present inventive concept relates to a method for optimizing water usage in a device utilizing water for a group of cleaning procedures, wherein the device comprises a sensor arrangement (518) and a data processing device, wherein the method comprises the steps of: determining a first substance content (400a) of first cleaning phase water from a first cleaning phase of the cleaning procedure (428) using the sensor arrangement (518); in the data processing device, receiving data comprising a target substance content interval requirement (844) of at least one of a plurality of cleaning phases (314); in the data processing device, comparing the first substance content to the target substance content interval requirement (844); and forming cleaning phase water to be used in the at least one of the plurality of cleaning phases (314) by transferring the first cleaning phase water to the at least one of the plurality of cleaning phases (314) based on the comparison.

A fluid circulation assembly for a dishwasher appliance includes a pump, a diverter, and a valve. The diverter includes an inlet and a plurality of outlet ports. The inlet of the diverter is in fluid communication with the pump for receiving fluid from the pump. The valve is in fluid communication with the diverter via one or more of the plurality of outlet ports. The valve includes a housing, a dual check valve assembly mounted in the housing and a plurality of conduits. The dual check valve assembly selectively directs fluid from the diverter to one or more of the plurality of conduits.

A water-conducting household appliance includes a moving component, an electric motor for moving the component, a load apparatus configured to apply a resistance to counter movement of the component as a function of a position of the moving component, and a control apparatus for actuating the electric motor. The control apparatus is configured to detect a drive current drawn which is drawn by the electric motor and is a function of the resistance applied by the load apparatus and to ascertain the position of the moving component as a function of the detected drive current.

A method and a dishwasher utilize a dock detection system to determine when a connector of a spray device is docked to a docking port provided on a manifold of the dishwasher. A dock detector is coupled to the docking port and is electrically coupled to a controller of the dishwasher through electrical conductors that extend along the manifold, thereby enabling a dishwasher controller to detect when spray devices are coupled to the manifold, e.g., to optimize a wash cycle to use a particular spray device docked to the docking port.

A dishwashing appliance includes a tub defining a wash chamber, a water storage chamber, an inlet defined in the tub and providing fluid communication into the wash chamber, and a heat pipe heat exchanger. The heat pipe heat exchanger includes a sealed casing, a working fluid contained within the sealed casing, a condenser section, and an evaporator section. The condenser section is in operative communication with the inlet upstream of the wet chamber. The dishwashing appliance also includes a fluid circulation system configured to deliver fluid to the wash chamber from the water storage chamber. The fluid circulation system includes a spray nozzle configured to spray wash fluid onto the evaporator section of the heat pipe heat exchanger.

A dishwasher and a control method thereof are disclosed. The dishwasher includes a tub accommodating an object to be washed, a spray arm rotatably provided inside the tub to spray wash water toward the object to be washed, a sump for storing wash water and collecting wash water sprayed into the tub therein, a filter separably mounted to the sump to remove foreign substances from wash water, a wash pump for supplying wash water stored in the sump to the spray arm, and a circulation passage for diverting at least a portion of the wash water supplied to the spray arm by the wash pump to the sump. After the dishes are washed, all of the wash water introduced into the wash pump is diverted into the filter. Foreign substances present in the wash water are collected in the filter and are discharged outside along with the wash water.

A dishwasher and silverware basket therefor include an interior sprayer integrated into the silverware basket and capable of directing a spray of fluid within one or more compartments of the silverware basket to assist in cleaning utensils such as silverware, cutlery, etc. housed within the silverware basket.

A liquid distributor for a liquid-transfer system of a conveyor dishwasher has first, second and third connections. The liquid sprayed in at least one final-rinse zone of the conveyor dishwasher can be fed to the liquid distributor via the first connection, wherein some of the liquid fed to the liquid distributor can be discharged, via the second connection, to a line system which can be connected to the second connection, and wherein the rest of the liquid fed to the liquid distributor can be discharged, via the third connection, to at least one line system which can be connected to the third connection. The liquid distributor has an interchangeable aperture component, which defines the fraction of liquid which is fed to the liquid distributor via its first connection and is to be discharged, via the second connection, to the line system which can be connected to the second connection.

A method of determining a position of a diverter of a fluid circulation system in a dishwasher appliance includes determining a total amount of water supplied to the dishwasher appliance; activating a pump at a predetermined speed in response to determining the total amount of water supplied to the dishwasher appliance, the predetermined speed being based on the determined total amount of water; measuring a fluid pressure of an amount of sump water provided within a sump of the dishwasher appliance after activating the pump at the predetermined speed, the amount of sump water being at least part of the total amount of water; and determining a position of the diverter in response to measuring the fluid pressure of the amount of sump water, the position of the diverter being dependent on the measured fluid pressure.
