A washing apparatus (e.g. a laundry washing machine, dishwasher, etc.) and method configure a wash cycle in part based on spectral data obtained from a spectrometer positioned with the washing apparatus and analyzed in a remote cloud service.

A warewasher has at least one treatment system comprising a jet system (60, 61, 62, 63, 202) with at least one jet for spraying treatment liquid onto the items within at least one treatment zone (32, 33, 201), a fresh water system and a control device (10), wherein the fresh water system has at least one water feed (71), with at least one fresh water inlet (70) for the introduction of fresh water into the at least one treatment zone (32, 33, 201) as well as a controllable capacitive deionization unit (50), wherein the at least one cell (50a, 50b) is designed to be operated in a deionization mode and in at least one further operating mode, wherein the control device (10) is designed to change the operating mode of the at least one cell (50a, 50b) in accordance with at least one operating parameter of the warewasher.

An appliance, system, and method for operating an appliance is provided. The appliance, system, and method are configured to execute operations including determining when a dispensing device for a detergent meets or exceeds a detergent level threshold, determining if a first wash mode corresponding to a performance wash mode is activated, and changing operation from the first wash mode to a second wash mode corresponding to an efficiency wash mode when the dispensing device meets or exceeds the detergent level threshold and the first wash mode is activated.

An appliance, system, and method for operating an appliance and determining presence of water softener at water provided to an appliance is provided. The system is configured to obtain a first water hardness value; obtain a second water hardness value based on a location of the appliance; determine a ratio of the first water hardness value and the second water hardness value; compare the ratio of the first water hardness value and the second water hardness value to a threshold limit; transmit a first water hardness signal when the threshold limit is exceeded, wherein the first water hardness signal corresponds to the first water hardness value; transmit, to the database storage device, a second water hardness signal when the ratio is within the threshold limit; and adjust operation of the appliance based on whether the first water hardness signal or the second water hardness signal is transmitted.

A dishwasher, in which a reservoir provided with an electrolyzer is connected to a water collector via a flow path change valve, and wash water in the reservoir is electrolyzed by the electrolyzer during non-operation of the wash water, to generate sterilizing water and to circulate the sterilizing water into the dishwasher, thereby achieving an enhancement in sterilizability of the dishwasher. A method for controlling a dishwasher makes it possible to suppress propagation of microorganisms left in the dishwasher and to remove organic substances, using a sterilizing agent or high-temperature water. It is also possible to reduce generation of offensive odor caused by decomposition of bacteria, through a reduction in the amount of bacteria in the dishwasher. Since sterilization of the dishwasher is automatically carried out, enhanced user convenience is provided.

The present invention relates to a dishwasher (1) comprising a tub (3) having more than one side wall (2), wherein the washing process is performed, a door (4) providing access into the tub (3) and a detergent dispenser (5) disposed on the door (4) wherein the chemical substances like detergent, softener and rinse aid are placed.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

A pump device for a water-conducting domestic appliance, such as a washing machine or a dishwasher, has a pump chamber with at least two inlets, and has multiple actuators on or in the pump chamber for a liquid-pumping operation in at least one direction. At least one sensor is provided on or in the pump chamber for determining constituents and properties of the liquid in the pump chamber. A storage chamber is connected to an inlet of the pump chamber and contains additives or analytes for the liquid.

Disclosed herein is a chemical dosing system for an appliance, such as a laundry washing machine or a dishwashing machine, having a water inlet, the system comprising a meter for determining the volume of water supplied to the appliance, a pump for dispensing a quantity of a chemical to the appliance and a control unit arranged to receive a signal from the meter and to cause to be dispensed to the appliance a volume of chemical that is proportional to the quantity of water supplied to the appliance. The disclosed system may enable a correct quantity of chemical to be automatically dispensed to many types of appliance, without the need to know anything about the appliance, or to derive electrical signal from the appliance.

A dishwasher includes: a tub which defines a space in which dishes are washed; a sump which accommodates washing water to be supplied into the tub; and a descaling solution supply device which supplies a descaling solution to the sump, in which the descaling solution supply device includes: a main flow path which guides washing water to be supplied to the sump; a solution accommodating unit which accommodates a descaling agent and has a solution outlet through which washing water, in which the descaling agent is dissolved, is discharged to the main flow path; a solution discharge valve which opens and closes the solution outlet; and a branch flow path which branches off from the main flow path, supplies the washing water into the solution accommodating unit, and has an atmosphere communicating port that communicates with the atmosphere.
