A method for controlling operation of a household appliance may include supplying a liquid to a first space, determining a first behavior(TB1) of temperature measured by a first temperature sensor during supplying of the liquid to the first space, supplying the liquid to a second space by activating a pump in order to transport the liquid from the first space to the second space, determining a second behavior (TB2) of temperature measured by a second temperature sensor during supplying of the liquid to the second space, and determining if a sufficient amount of the liquid has been supplied to the second space or not based on the second behavior (TB2) evaluated with respect to the first behavior (TB1). A household appliance may also be provided.

A dishwasher system for cleaning dishes may include a dishwasher tub configured to house dishes therein and run a dishwasher cycle, a door assembly configured to selectively seal the dishwasher tub, the door assembly including an inlet nozzle arranged on the inside of the door assembly, the inlet nozzle extending across the width of the door at the top of the door assembly to receive hot and moist air post wash from the dishwasher tub, and a duct fluidly connected to the inlet nozzle and configured to transfer the air through the door assembly and out an outlet nozzle during a drying phase of the dishwasher cycle prior to the door assembly being opened post-cycle.

A dishwasher is disclosed. When the dishwasher performs a drying process, the dishwasher increases a temperature of a washing space before air inside the washing space is discharged, thereby maintaining the temperature of the washing space at an appropriate drying temperature and increasing efficiency of the drying process.

Provided are a method performed by an appliance for washing and rinsing goods, where some of the goods loaded into the appliance are sensitive to process water temperature changes, and an appliance performing the method. The method may include receiving via a user interface, an instruction that an appliance, during execution of a general-type washing program, should take into account that goods sensitive to temperature changes are loaded into the appliance, measuring a temperature value in a washing compartment of the appliance upon executing a draining process, and supplying fresh water to the washing compartment of the appliance. The method may include measuring, when the fresh water has been supplied, whether the process water being accommodated in a sump of the appliance is at a target temperature value or not and if not adjusting the temperature of the process water in the sump to attain the target temperature value.

A method for removing stains, in particular tea stains, during a cleaning cycle of a household appliance, such as a dishwashing machine. The cleaning cycle comprises at least a main wash cycle. A cleaning agent is released during the main wash cycle when the temperature inside the household appliance during the main wash cycle exceeds a predetermined temperature threshold, the threshold being higher than about 40° C., for example higher than about 55° C.

A dishwasher system for cleaning dishes may include a dishwasher tub configured to house dishes therein and run a dishwasher cycle, a door assembly configured to selectively seal the dishwasher tub, the door assembly including an inlet nozzle arranged on the inside of the door assembly, the inlet nozzle extending across the width of the door at the top of the door assembly to receive hot and moist air post wash from the dishwasher tub, and a duct fluidly connected to the inlet nozzle and configured to transfer the air through the door assembly and out an outlet nozzle during a drying phase of the dishwasher cycle prior to the door assembly being opened post-cycle.

A warewash machine includes a housing defining a ware inlet, a ware outlet and an internal chamber including a plurality of sequential spray zones including at least one wash zone and a rinse zone downstream of the wash zone in a ware conveyance direction. A vent path leads from the chamber leading to a vent outlet for connecting to a building ventilation system. A damper is provided for controlling a flow area at a location along the vent path. A controller is connected to control a position of the damper, the controller configured to adjust a position of the damper based upon input from at least a first temperature sensor, wherein the first temperature sensor is located at one of (i) the ware inlet, (ii) the ware outlet or (iii) along the vent path. Methods of operating a warewash machine are also provided.

A dishwashing appliance may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, a cold water line, and a fan or a variable-flow restrictor. The tub may define a wash chamber. The pump may be configured to deliver a wash fluid to the wash chamber. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within the wash chamber. The path inlet may be defined in fluid communication between the wash chamber and the path outlet. The path outlet may be defined in fluid communication between the path inlet and the wash chamber downstream from the path inlet. The cold water line may define a cold water nozzle disposed within the fluid recirculation duct to provide a condensing, coldwater flow into the fluid recirculation duct between the path inlet and the path outlet.

A dishwashing appliance may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, a cold water loop, a heat exchanger, and a tub fan. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within a wash chamber. The cold water loop may define a cold water nozzle disposed within the fluid recirculation duct to provide a condensing, cold-water flow into the fluid recirculation duct between the path inlet and the path outlet. The heat exchanger may be mounted to the cold water loop outside of the fluid recirculation duct to cool water within the cold water loop. The tub fan may be configured to selectively motivate an airflow from the path inlet to the path outlet.

A device having a clean status indicator system having a frame with a base, a plurality of feet, a washing compartment, a door, and at least one rack. The system includes a weight sensor secured to one of the feet; a tilt switch for indicating if the dishwasher is tilted; a temperature sensor; a housing, and a visual display. A controller having a control logic communicates with a power supply, the weight sensor, the tilt switch, the temperature sensor, and the visual display. The controller is configured to receive data from the weight sensor, the tilt switch, and the temperature sensor and analyze the data from the weight sensor, the tilt switch, and the temperature sensor. The tilt switch is mounted exterior to the dishwasher and configured to be activated or deactivated when the dishwasher is a tilted forward.
