An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.

A dishwasher having a washing container; a controller to control the operation of the dishwasher by means of a wash program; a desorption drying system to dry items to be washed that are arranged inside the washing container; and input means that are connected to the controller and that modify the wash program.

A water-bearing domestic appliance and method of operating a water-bearing domestic appliance, wherein the domestic appliance includes a water feed system that is controlled by a control device and that supplies a measured volume of water to the domestic appliance. The domestic appliance further includes a total water volume detection device to detect a total volume of water that is supplied via the water feed system to the domestic appliance during its service life.

A dishwasher includes an independent presoak system which may be activated by a user of the dishwasher. The dishwasher presoak system utilizes a storage tank, supply tubes, and set of nozzles which are independent from components used in a washing cycle such that a presoak detergent is applied to items placed within a washing compartment of the dishwasher without being diluted by a standard wash cycle. As part of the presoak system, the dishwasher features a detection system which allows the user to select an automatic presoak operating state whereby the dishwasher utilizes a sensor to determine if items placed into the washing compartment are sufficiently dirty to need a presoak cycle prior to a washing cycle. The dishwasher further relies on a control system to analyze samples taken of the dirtiness levels of items placed within the washing compartment and determine whether a presoak option is necessary or suggested.

A method and device for controlling a domestic appliance connected to an electric grid so as to allow smart metering, wherein electric power consumed according to different consumption tariffs is measured and the domestic appliance receives information about the availability of a currently applicable consumption tariff or a switch-off condition for preventing peak loads in the grid. The domestic appliance is operated as follows: a) when an inexpensive consumption tariff is available, the appliance is put into operation as intended, and the history of the cleaning process is continuously recorded; b) when an inexpensive consumption tariff is not available or the switch-off condition is met, the appliance is not put into operation or a previously started operation is interrupted; and c) when information about an inexpensive consumption tariff is available, the domestic appliance resumes operation, and a component of a detergent is added based on the recorded history.

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.

Method for operating a shortened dishwashing cycle of a dishwasher, dishwasher configured for running the shortened dishwashing cycle and computer program product for operating a shortened dishwashing cycle of a dishwasher. The dishwasher (10) includes a tub (12) configured to hold dishware during a dishwashing cycle, at least one circulation pump (50, 250), at least one heating element (230), and a controller (40, 240) configured to operate the dishwasher. The controller (40, 240) is configured to operate the dishwasher (10) according to at least one of a normal dishwashing cycle or the shortened dishwashing cycle. The method includes providing a first amount of warm water to the tub (12). The first amount of warm water is greater than a standard amount of water provided to the tub (12) for the normal dishwashing cycle. The method further includes, while the first amount of warm water is being provided into the tub (12), pulsing the circulation pump (50, 250) based on a predetermined timing sequence and activating the heating element (230) to heat the water within the tub (12).
