Provided is a method of operating a dishwasher including a heat pump circuit, wherein a condensate collection container is associated with an evaporator of the heat pump circuit. The method may include the steps of pumping a washing liquid from a sump of the dishwasher using a pump device, opening a first valve in a condensate conduit connecting the condensate collection container with a suction conduit of the pump device, pumping a condensate from the condensate collection container using the pump device. A dishwasher may also be provided.

A water-conducting domestic appliance includes a washing container, a door which is pivotably mounted to the washing container to define with the washing container a washing chamber for washing items, and a door opening module configured to automatically open the door. A detector detects a presence of a living being in a defined area in front of the domestic appliance. In the event the presence of a living being has been detected by the detector in the defined area, a control device prevents the door opening module from automatically opening the door.

Provided is a dishwashing machine determining whether a nozzle spraying washing water is clogged, and a method for controlling the same. In according to one aspect, the dishwashing machine may include a main body; a washing tub provided in the main body; a basket provided in the washing tub for accommodating dishes; a plurality of fixed nozzles fixedly arranged in a first direction of the washing tub and spraying washing water in a second direction; a vane provided for deflecting washing water sprayed from the fixed nozzles towards dishes accommodated in the basket, the vane being linearly reciprocated in the second direction; and a controller determining whether the vane is linearly reciprocated in the second direction in parallel with the first direction.

A domestic dishwasher is provided, which has a main controller, a sorption drying device, and an additional controller to specifically control an electrical component of the sorption drying device.

A system includes a dishwasher, an image capturing device designed to capture an image of washware arranged in the washing chamber, with the image including a plurality of sub-images, each of which having different spectral information of the washware. An illumination unit illuminates the washware in the washing chamber, and an image analysis unit receives the captured image from the image capturing device and to carry out a chemical analysis of soiling on the washware based on the plurality of sub-images of the received image and to ascertain a dirt characteristic of soiling as a result of the chemical analysis. A control device carries out a washing program for washing the washware in the washing chamber. The control device receives the dirt characteristic from the image analysis unit and adapts the washing program for washing the washware as a function of the received dirt characteristic.

A dishwasher appliance includes a spray detection sensor and a variable speed pump. Based upon signals from the spray detection sensor, a speed of the variable speed pump is changed. By changing the speed of the variable speed pump, a trajectory of wash fluid from a spray assembly of the dishwasher appliance is also changed such that the wash fluid is directed towards a detergent dispenser of the dishwasher appliance. A related method for operating a dishwasher appliance is also provided.

A flow through chemical sensor includes a housing having a through passage along which chemical can flow, a sidewall of the housing having first and second openings that communicate with the through passage. A first electrode is mounted on the housing and aligned with the first opening, the first electrode of a plate configuration with a unitary depression that extends through the first opening and to a peripheral edge of the through passage. A second electrode is mounted on the housing and aligned with the second opening, the second electrode of a plate configuration with a unitary depression that extends through the second opening and to the peripheral edge of the through passage. A method of detecting presence or absence of chemical is also provided.

A household dishwasher includes a dishwasher cavity, and a receptacle for items to be washed. The receptacle can be shifted into and at least partially out of the dishwasher cavity. An electric motor having a motor parameter is designed to shift in a driving state the receptacle into or at least partially out of the dishwasher cavity and is decoupled in a free-running state from the receptacle and/or disconnected from a power supply. A detection unit detects a blockage of the receptacle and/or a stop request of a user as a function of the motor parameter, and a switching unit switches the electric motor into the free-running state as a function of the detected blockage or the detected stop request.

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.

A dishwasher appliance includes a tub defining a wash chamber for receipt of articles for washing, a fluid delivery device configured for delivering wash fluid into the wash chamber, and a camera assembly mounted with a view of the wash chamber including a location where the fluid delivery device is configured for delivering the wash fluid. A controller is configured to obtain consecutive images of the wash fluid in the wash chamber, determine whether the fluid delivery device is providing acceptable delivery of the wash fluid into the wash chamber, wherein the determining includes using the consecutive images of the wash fluid to determine whether there are differences in the wash fluid present in the wash chamber, and initiate corrective action if the fluid delivery device is not providing an acceptable delivery of the wash fluid into the wash chamber.
