Provided herein is a method performed by an appliance for washing and rinsing goods of detecting process water added to a sump of the appliance during interruption of operation of the appliance, upon recommence of appliance operation, and an appliance performing the method. The method may include detecting process water added to a sump of the appliance during interruption of operation of the appliance, upon recommence of appliance operation. The method may include increasing operating speed of a circulation pump of the appliance to a target speed, measuring an indication of circulation pump pressure or process water flow rate through the circulation pump, and determining that process water has been added to the sump of the appliance during the interruption in case the measured pressure or flow rate is maintained at a sufficient level after the speed of the circulation pump has reached the target speed.

A cleaning device (110) for cleaning articles (112) to be cleaned is proposed. The cleaning device (110) includes at least one cleaning chamber (118) for receiving the articles (112) to be cleaned. In addition, the cleaning device (110) includes at least one application device (124) for acting upon the articles (112) to be cleaned with at least one cleaning fluid. The cleaning device (110) additionally comprises at least one cooling surface (158) which points to the cleaning chamber (118) and at least one cooling container (160) which is thermally coupled with the cooling surface (158) for receiving a cooling liquid. The cleaning device (110) comprises at least one control system (178) which is set up to control at least one regeneration step in the cleaning device (110). The regeneration step includes the following substeps: d) fill the cooling container (160) with cooling liquid; e) heat the cooling liquid in the cooling container (160); and f) remove the cooling liquid from the cooling container (160).

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 dishwasher has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

Methods of operating a dishwashing appliance are provided herein. A method may include measuring a temperature at a temperature sensor and identifying a runaway heat condition within a wash chamber based on the measured temperature. The method may also include directing a volume of water to the wash chamber in response to identifying the runaway heat condition and circulating the volume of water within the wash chamber for a recirculation period.

A method of diagnosing level sensor failure in a fuel cell water trap, the method may include: determining whether a water level of a level sensor is changed in a fuel cell water trap, adding an amount of charge according to an operating time and comparing the added amount of charge with a preset threshold amount of charge, according to the result of the forcibly opening a drain valve according to determining whether a channel voltage of a specific channel is abnormal as the result of the comparison, and diagnosing a failure of the level sensor according to determining whether the channel voltage of the specific cell is recovered as a normal state when the drain valve is opened.

A dishwasher utilizing one or more sprayer rings disposed proximate to one or more tines of a dishwasher rack, where the sprayer ring(s) are in fluid communication with a fluid supply that is configured to supply a fluid to the one or more sprayer rings to spray fluid onto utensils disposed within the wash tub.

A water-using household appliance, in particular a household dishwashing machine, includes a wall which is made from a metal material, and a device which is made from a plastic material and fixedly connected to the wall by a laser weld.

A dishwasher includes: a dishwasher body including a tub that defines a washing space and a sump disposed vertically below the tub and configured to accommodate washing water; a heat pump including a compressor, a condenser, an expansion apparatus, and an evaporator; a drain storage unit connected to a drain pipe of the sump and configured to receive washing water discharged from the sump; a drain pipe open-close valve that opens and closes the drain pipe; and a controller that controls the heat pump and the drain pipe open-close valve. The evaporator is configured to exchange heat with the drain storage unit, and the controller controls the drain pipe open-close valve to open the drain pipe to move washing water of the sump to the drain storage unit when the sump is drained.

The present inventive concept relates to a device (500) utilizing water for a group of cleaning procedures, wherein each cleaning procedure (100) in the group of cleaning procedures comprises a plurality of cleaning phases (102, 104, 106, 108) each using cleaning phase water having a substance content with respect to a number of substances, wherein the device (500) comprises a sensor arrangement (554) configured to determine a first substance content (110) with respect to at least one of the number of substances in first cleaning phase water from a first cleaning phase (102) being part of the plurality of cleaning phases (102, 104, 106, 108); wherein the device (500) is configured to end the first cleaning phase (102) if a pre-determined condition related to the first substance content (110) and associated with the first cleaning phase (102) has been met.
