A water-conducting household appliance has a closable treatment chamber, in order to treat articles therein, at least one chamber water inlet into the treatment chamber, at least one sump under said treatment chamber, a coarse particle filter for separating coarse particles having a size ≥5 mm from water exiting from the sump, wherein the coarse particle filter has a coarse particle filter inlet, a coarse particle filter water outlet and a coarse particle filtrate outlet. According to the invention, exactly one pump having a pump inlet and a pump outlet is provided for the entire household appliance, said pump being connected downstream of the sump and the coarse particle filter water outlet. Water lines, valve devices and a discharge outlet from the household appliance are also provided, wherein a water line leads from the coarse particle filter water outlet to the pump or to the pump inlet.

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.

Proposed is a home appliance that includes a cabinet defining an exterior of the home appliance; a reception space defined inside the cabinet and configured to receive objects in the reception space; a door configured to open/close an open surface of the reception space, the door having a viewing window provided at the door; a lamp configured to illuminate an inside of the reception space; a sensor assembly configured to output a knock-on signal based on detecting a user's knock; and a controller configured to turn on/off the lamp based on the knock-on signal output by the sensor assembly, wherein based on a present state of the home appliance corresponding to at least any one of a plurality of preset exceptional situations, the controller is configured to not turn on/off the lamp regardless of the knock-on signal being output.

A pump of a dishwasher has an integrated heating element, a pump chamber with an inlet and an outlet, a pump rotor inside the pump chamber and a drive motor, wherein the heating element and a temperature sensor are provided on a wall of the pump chamber. For measuring a calcification of the pump chamber it is filled with water and then the pump rotor rotates for mixing the water in the pump chamber without transporting water out of the pump chamber. The temperature of the water in the pump chamber is measured with the temperature sensor as a starting temperature, and then the heating element is activated to heat the water in the pump chamber while the temperature of the water in the pump chamber is measured. Then the heating element is deactivated and the maximum temperature of the water during the heating duration or directly afterwards is determined. A temperature relation between the maximum temperature and the starting temperature of the water is calculated. These steps are executed in the pump at the very beginning of an operation of the new dishwasher after its installation for determining an initial temperature relation. These steps are automatically executed again at a later stage for determining a later temperature relation to determine the heating efficiency of the pump by comparing the later temperature relation to the initial temperature relation.

A household dishwasher includes a receiving compartment for receiving an item to be washed, a pump sump, and a heat pump assembly through which, during operation, a heat transfer medium flows. The heat pump assembly includes a plate condenser configured to enable a transfer of heat from the heat transfer medium to a washing liquor circulating in the household dishwasher. A spray assembly supplies washing liquor to the item to be washed. A first flow path extends from the pump sump to the spray assembly for conducting the washing liquor, and a second flow path extends from the pump sump to the plate condenser. Means are provided to prevent or hinder foreign matter that is swept along with the washing liquor from adhering to a washing-liquor-facing surface of the plate condenser, or to detach foreign matter adhering to the washing-liquor-facing surface from said surface.

A cleaning method includes sensing at least one trigger, where the at least one trigger is chosen from sensing a presence of a first liquid within a wash compartment of an appliance with a liquid sensor and sensing an elapsed time from activation of a faucet of the appliance with a timer. The cleaning method also includes draining the first liquid from the wash compartment of the appliance. Additionally, the cleaning method includes rinsing the wash compartment with a second liquid. The draining of the first liquid from the wash compartment of the appliance and the rinsing of the wash compartment with a second liquid are both performed prior to initiating a wash cycle of the appliance.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

A dishwasher, comprising: a wash tub; a sprayer configured to spray fluid within the wash tub; an imaging device configured to capture images within the wash tub; and a controller coupled to the imaging device and configured to perform a remote start of a wash cycle in the dishwasher in response to receiving a remote start command from a remote device by: controlling the imaging device to capture one or more images within the wash tub; initiating communication of the captured one or more images to the remote device for viewing on the remote device; waiting to receive a confirmation from the remote device; and starting the wash cycle in response to receiving the confirmation from the remote device.

Example embodiments provide a dishwasher comprising a tub; a door configured for selectively sealing a forward access opening of the tub; a detergent dispenser located at an inner surface of the door; a spray arm mounted within the tub such that the spray arm is adjustable between a first height and a second height, the spray arm comprising a spray detergent nozzle; and a circulation pump configured to supply washing liquid to the spray arm. The dishwasher is characterized in that the spray arm is configured to emit a fan-shaped jet from the spray detergent nozzle when the washing liquid is supplied to the spray arm and the spray arm is configured to emit the fan-shaped jet that is incident upon the detergent dispenser both when the spray arm is positioned at the first height and when the spray arm is positioned at the second height.

A system includes a dishwasher including a washing chamber, a sensor unit designed to detect a time curve of at least one sensor signal of a washing liquor and to output the detected time curve of the at least one sensor signal, a memory unit designed to store the time curve of the at least one sensor signal, an ascertaining unit designed to ascertain a temporal functional value based on the time curve of the at least one sensor signal, and a control device designed to carry out a washing program for washing washware in the washing chamber of the dishwasher and to carry out a specified action as a function of the temporal functional value..
