A method for operating a dishwasher appliance includes receiving data indicating a status of hot water within a water heater appliance, receiving data indicating a status for a cycle of a dishwasher appliance, and initiating a start for the cycle of the dishwasher appliance in response to the data indicating the status of hot water within the water heater appliance indicating available hot water.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. Separate entrance and exit openings may be provided in some instances to minimize employee interaction with unwashed customer beverage containers.

A control method for a dishwasher that includes a spray arm, a sump configured to provide a space where washing water is stored and to collect washing water sprayed from the spray arm, a housing configured to connect the sump and the spray arm, a heater located in the housing, an impeller located in the housing and above the heater, and a motor configured to rotate the impeller, is described. The control method includes the actions of supplying washing water to the sump; rotating the impeller by supplying electricity to the motor; measuring an amount of electric current supplied to the motor during the rotating of the impeller; and heating washing water located in the housing by operating the heater based on the amount of electric current supplied to the motor during the rotating of the impeller being greater than or equal to a preset reference amount.

A dishwasher and a method for controlling a dishwasher are provided. The dishwasher may include a washing tub that defines a washing space in which one or more dishes may be placed; an injection unit that injects wash water to the dishes; a sump provided underneath of the washing tub; a drive that supplies and circulates the wash water stored in the sump to the injection unit; and a drainage pump that drains the wash water from the sump. The method for controlling the dishwasher may include supplying wash water to the dishwasher; washing dishes using the wash water; rinsing the washed dishes; and drying the dishes. The method may further include exhausting by operating the drainage pump for a predetermined period of time to exhaust air from the drainage pump after the supplying of the wash water to the dishwasher.

A method of controlling a dishwasher includes washing an object accommodated inside a tub by spraying water and detergent onto the object, rinsing the object by spraying water onto the object, drying the object by removing moisture adhered to the object, detecting an amount of a rinsing agent, comparing the detected amount of the rinsing agent to a predetermined amount, based on the comparison, determining whether the detected amount of the rinsing agent is less than the predetermined amount, and increasing at least one of a temperature of water to be supplied in the rinsing or a drying time in the drying based on determining that the detected amount of the rinsing agent is less than the predetermined amount.

A dishwasher and method utilize an imaging system to perform various diagnostic operations within the dishwasher, including one or more of level sensing, filter cleaning, wash tub rinse down, foam detection, imaging system cleaning, and remote viewing. A controller may clean a filter by controllably-redirecting a controllably-movable sprayer to spray fluid onto the filter.

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 disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pre-determined volume or timed flow of water, and exposure time of sanitizer(s) to the intended objects. The spray embodiment has high performance conical spray nozzle(s) controlled by a controller that reduces water usage and that may vary depending on the viscosity of the material to be eliminated. The recirculating embodiment has a recirculating water system, with a controller operating the components that recirculate water throughout the system until the turbidity exceeds a chosen threshold, and displace with fresh water until the turbidity returns to a lower threshold. The water resumes recirculation until it again exceeds the chose turbidity threshold and the water in the system is again displaced by fresh water. Both spray and recirculating embodiments can contain multiple rinse stations.

A fluid circulation system for dishwasher appliances includes a sump and a pump. The fluid circulation system further includes a filter at least partially disposed within a chamber of the sump and surrounding an impeller of the pump. The fluid circulation system includes a diverter. The fluid circulation system further includes a cleaning manifold disposed proximate an outer surface of a sidewall of the filter, the manifold defining a plurality of apertures for flowing fluid towards the outer surface of the sidewall of the filter.

A device for rinsing a container or other kitchen utensil, the device including a rinsing pan equipped with a spray nozzle for a rinsing liquid, the spray nozzle being supplied with the rinsing liquid by a supply line that is part of the device, and the rinsing pan being provided with an outlet for discharging the rinsing liquid. The device includes a chamber which delimits an at least partially closed space above the rinsing pan, the chamber having a passage opening for introducing the container in order to rinse it, and for removing the container after rinsing.
