A household dishwasher includes a dishwasher cavity, a door attached pivotably to the dishwasher cavity, a door opening and closing device for automated opening and closing of the door, and a control unit designed to actuate the door opening and closing device. The control unit is designed to detect a motor current of a drive element of the door opening and closing device and to evaluate the detected motor current as to whether the door opening and closing device is functional or non-functional.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a drain pump, a turbidity sensor, and a controller. The tub may be positioned within the cabinet and defining a wash chamber for receipt of articles for washing. The spray assembly may be positioned within the wash chamber. The drain pump may be in fluid communication with the wash chamber. The turbidity sensor may be mounted within the cabinet. The controller may be in operative communication with the turbidity sensor and the drain pump. The controller may be configured to initiate a wash operation. The wash operation may include initiating a rinse cycle, obtaining an image of the wash chamber, determining calibration viability for the turbidity sensor based on the obtained image, and adjusting a calibration state of the turbidity sensor based on the determined calibration viability.

A wash monitoring system including a water flow meter that transmits water flow readings of flow through a water line, chemical conduits with color sensors on the chemical conduits and configured to transmit color readings of a chemical within the chemical conduits, and chemical flow meters on the chemical conduits that transmit chemical flow readings of flow through the chemical conduits. The system includes a memory containing processor-executable instructions that cause processors to compare the water flow readings with a range of water flow readings, compare the chemical flow readings with a range of chemical flow readings, compare the color readings with a range of color readings associated with each of the one or more chemical conduits, and initiate an alarm if one of the water flow readings, the chemical flow readings, or the color readings are not within the respective ranges of readings.

A system includes a dishwasher including a dishwasher cavity, a spray facility for applying washing liquor and/or fresh water to dishes accommodated in the dishwasher cavity, a drive facility for actively driving the spray facility, and a control apparatus for activating the drive facility depending on a control signal. An input unit detects a user input for moving the spray facility, and a generation unit generates the control signal depending on the user input detected.

The present disclosure relates to a dishwasher. The dishwasher according to an embodiment comprises: a tub having a washing room, in which an object to be washed is accommodated, formed therein; a nozzle which is arranged in the washing room and sprays washing water to the object to be washed, and includes a magnetic body at one end thereof; a coil which his formed to surround a region corresponding to a movable range of the nozzle, and through which an electric current flows according to the rotation of the nozzle; and a controller which controls an operation of the nozzle according to an operation command, and determines an operating status of the nozzle on the basis of a value of the voltage generated in the coil.

Systems and methods of detecting current leakage in a heating element are provided. An alternating current signal can be applied to the heating element. The heating element can have an associated line relay and an associated neutral relay coupled to a line terminal of the heating element and a neutral terminal of the heating element, respectively. A control system can be configured to control a sequence of operations of the line and neutral relays such that the magnitude of a leakage current flowing through the heating element to ground is increased. Such increased magnitude can facilitate detection of the leakage current. The detected leakage current can be compared with a leakage threshold. The control system can cease the operation of the heating element if the leakage current is greater than the leakage threshold.

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 and method utilize a cam-based position sensor that is configured to sense multiple rotational positions for a discretely directable tubular spray element driven by a tubular spray element drive.

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 household appliance for treating at least one item according to at least one cycle of operation includes a treating chamber for receiving the at least one item for treatment according to the at least one cycle of operation, a treating chemistry dispenser receiving a unit dose container having an electrically conductive element, a physical alteration element located proximate to the treating chemistry dispenser and operable to physically alter at least a portion of the electrically conductive element and a sensor for sensing the physical alteration.
