20220104684 · 2022-04-07 ·

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a circulation pump, a pressure sensor, and a controller. The circulation pump may be in fluid communication with a wash chamber defined by the tub. The pressure sensor may be upstream of the circulation pump. The controller may be configured to initiate a washing operation including activating the circulation pump, detecting movement of the door from a closed position, detecting return of the door to the closed position, calculating a modified time period for flood detection, determining pressure at the pressure sensor exceeds a pressure threshold following detecting return of the door to the closed position, initiating the modified time period in response to determining pressure at the pressure sensor exceeds the pressure threshold, and directing the circulation pump based on measuring the elevated pressure and expiration of the modified time period.

A DISHWASHING MACHINE AND METHOD

Dishwashing machine comprising: a controller; a spray arm assembly comprising a spray arm having one or more spray holes for spraying a washing load with water, and a pipe for delivering water to the spray arm; a pump for pumping water through the pipe and to the spray arm; the pipe being constructed and arranged to at least partially restrict flow of water from the pump to at least a part of the spray arm dependent on spray arm orientation relative to the pipe, a power consumption of the pump thereby being dependent at least in part on the spray arm orientation relative to the pipe; and the controller being configured to monitor the power consumption of the pump in order to determine rotational information of the spray arm.

Dishwashing appliances with hot start features and related methods

A method of operating a dishwashing appliance includes filling the sump of the dishwashing appliance with an initial fill of water of a current operational cycle and measuring a temperature of the initial fill of water. The method also includes comparing the temperature of the initial fill of water to a reference temperature and calculating an energy demand for the dishwashing appliance to heat the initial fill of water to the reference temperature based on a heat rise rate. Based on the calculated energy demand, for example based on a comparison of the calculated energy demand with a predetermined energy demand for an external heating unit, the dishwashing appliance decides whether to heat the initial fill. The heat rise rate may be calculated during a characterization of the dishwashing appliance prior to the current operational cycle.

REUSABLE FOOD OR BEVERAGE CONTAINER WASHING SYSTEM
