A dishwasher may include a closure element, such as a door, a user interface on the closure element, and a controller. A data communication link having a first data connector may be coupled to the controller, and a second data connector may be coupled to the user interface. The first and second data connectors may communicatively couple when the closure element is in the closed condition to establish data communication between the controller and the user interface. The communication link may also form a power link to provide power to the user interface across an electrical link.

A dishwasher having a tub having an open face and at least partially defining a treating chamber for holding dishes during an automatic cycle of operation, a door moveably mounted between an opened position, wherein a user the treating chamber is accessible, and a closed position, wherein the door closes the open face of the tub and dispensing assembly configured to activate an indicator to emit a human-detectable signal in response to a first signal indicating a predetermined amount of treating chemistry and a second signal indicating a predetermined amount of illumination.

A conveyor dishwasher (2) includes a final rinse zone (18) and at least one wash zone (12, 14, 16, 18) and also a conveyor apparatus for conveying washware through the treatment zones of the conveyor dishwasher (2), wherein the at least one wash zone (12, 14, 16, 18) has an associated wash tank (32, 34, 36) in which at least a portion of the wash liquid which is sprayed in the at least one wash zone (12, 14, 16, 18) is collected. The conveyor dishwasher (2) also has a wastewater pump (61) for supplying wash liquid, which is produced as wastewater during operation of the conveyor dishwasher (2), to a heat exchanger device (60) in which at least a portion of the thermal energy of the supplied wash liquid is transferred to the final rinse liquid which is to be sprayed in the final rinse zone (18).

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

In a method for operating a dishwasher, a desorption process of a reversibly dehydratable dry material of a sorption-drying system is initiated at least at times. A parameter that influences the desorption process is hereby evaluated for determining an instant for performing the desorption process.

The invention relates to a method of automatic dishwashing in a dishwasher having a wash tank, comprising: in a first step, delivering a first composition to dishware in the tank in the form of a mist; and afterwards, in a second step, delivering a second composition to the dishware in the tank in the form of a jet; wherein the first and second compositions are different, the first composition comprises a bleach, and the second composition is alkaline and comprises a builder. The invention also provides a dishwasher adapted to carry out the inventive method.

A dishwashing appliance and method of operation are provided herein. The dishwashing appliance may include a heater operable to heat a tub of the dishwashing appliance. The method may include directing water into the tub, activating the heater by supplying electrical power to the heater, and adjusting the electrical power to the heater. Adjusting the electrical power may include detecting a temperature change within the tub, determining when the temperature change meets a predetermined criterion, and delivering a wattage output from the heater when the predetermined criterion is met.

A dishwasher including a washing chamber to perform dishwashing, a water collecting portion provided at a lower portion of the washing chamber to gather water used for washing, and a sensing module which is disposed in the water collecting portion and integrally includes a water sensing sensor to sense whether or not water is present and a temperature sensor to sense a temperature of water. Since the sensing module simultaneously serves as the water sensing sensor and the temperature sensor, it may be possible to more efficiently utilize an inner space of the water collecting portion.

A dishwasher and method for treating dishes according to a cycle of operation, the dishwasher comprising a tub at least partially defining a treating chamber and a dish rack movably received within the treating chamber. The dishwasher configured for receiving dishes for treatment during the cycle of operation, and moveable relative to the tub. A sprayer located within the treating chamber, configured to emit spray into the dish rack, where a diverter and thermally-responsive actuator within the sprayer can change the direction of the spray.
