A method and dishwasher utilize a spray basket that includes a container body that defines a compartment for retaining utensils as well as multiple sets of nozzles, a portion of which are configured to direct a spray of fluid into the compartment, and another portion of which are configured to direct a spray of fluid external from the container body. The spray of fluid directed external from the container body may be used, for example, to provide a power wash zone adjacent to the spray basket to assist in cleaning other utensils in a dishwasher.

Dishwashing appliances and methods, as provided herein, may include features or steps such as detecting a pressure (P1) at a pressure sensor upstream from a pump while maintaining the pump in an inactive state and activating the pump from the inactive state for an activation period during which the pump remains active to motivate a continuous fluid flow. Dishwashing appliances and methods may further include features or steps for detecting a pressure (P2) at the pressure sensor upstream from the pump during the activation period and initiating a response sequence at the pump based on P1 and P2.

A dishwasher appliance equipped with leak detection features and a method of detecting leak conditions during an operation cycle of a dishwasher are provided. In one aspect, the dishwasher appliance includes a tub having a sump. A pressure sensor is mounted to the sump and is configured to monitor the sump pressure during an operation cycle. If the sump pressure falls below a pressure threshold during a circulation cycle, corrective action can be taken. For instance, a circulation pump circulating wash fluid through the tub can deactivated and a static pressure reading can be taken by the pressure sensor. The static pressure reading can be compared to a static pressure reading taken prior to the circulation cycle. In response to whether the static pressure is within a predetermined range of the static pressure reading taken prior to the circulation cycle, the circulation cycle can be recommenced or aborted.

A dishwasher comprising a tub, a reuse tank, and a controller for implementing a wash cycle in the tub, the controller comprising a clock, the controller operably coupled to a recirculation pump and a drain pump, the controller configured (a) to cause the recirculation pump to supply liquid used during the wash cycle to the reuse tank, (b) to monitor via a clock a period of time that the liquid is within the reuse tank, and (c) when the period of time is greater than a predetermined period of time, (i) to cause a control valve in an outlet conduit to open and allow the liquid to flow from the reuse tank to a sump and (ii) to cause a drain pump to drain the liquid from the sump and out of the dishwasher.

A conveyor dishwasher (1) for washing washware has at least one final rinse zone (30, 40) and at least one washing zone (10, 20) whichas seen in the conveying direction (T) of the washwareis arranged upstream of the at least one final rinse zone (30, 40). A sensor device (5) is provided for detecting at least one parameter which characterizes the quality of the liquid which is to be sprayed in the at least one washing zone (10, 20), wherein the conveyor dishwasher (1) has a liquid transfer system which is designed, for the purpose of regenerating the washing liquid which is to be sprayed in the at least one washing zone (10, 20), to preferably as required supply an in particular definable quantity of fresh water to the at least one washing zone (10, 20).

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 method of operating a dishwasher includes a tub that at least partially forms a treating chamber and a reuse tank fluidly coupled to the tub for storing liquid from the tub for subsequent reuse in the treating chamber. The method includes supplying liquid from the reuse tank to the tub, sanitizing liquid in the tub by heating the liquid to a sanitizing temperature by operating a heating element located in the tub and maintaining the liquid at or above the sanitizing temperature for a sanitizing time period sufficient to sanitize the liquid, and supplying the liquid in the tub to the reuse tank after sanitizing to sanitize the reuse tank.

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 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.

Provided are a method performed by an appliance for washing and rinsing goods, where some of the goods loaded into the appliance are sensitive to process water temperature changes, and an appliance performing the method. The method may include receiving via a user interface, an instruction that an appliance, during execution of a general-type washing program, should take into account that goods sensitive to temperature changes are loaded into the appliance, measuring a temperature value in a washing compartment of the appliance upon executing a draining process, and supplying fresh water to the washing compartment of the appliance. The method may include measuring, when the fresh water has been supplied, whether the process water being accommodated in a sump of the appliance is at a target temperature value or not and if not adjusting the temperature of the process water in the sump to attain the target temperature value.
