A dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising an outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit and through the outlet in the rotatable spray arm.

A dishwasher and method of operating a dishwasher according to a cycle of operation are described herein. The dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising a nozzle outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit.

A dishwasher may include a washing chamber and a wash arm arrangement having a wash arm rotatably arranged in the washing chamber, and a satellite spray device arranged on the wash arm. The dishwasher may include at least one sensor configured to sense a rotational position of the wash arm and a control unit configured to monitor consecutive sensed rotational positions of the wash arm. The control unit may be configured to calculate a rotational speed of the wash arm based on an elapsed time and a rotational distance between two sensed rotational positions, and may be configured to estimate a current rotational position of the wash arm based on an elapsed time since a previously sensed rotational position and the calculated rotational speed. The control unit may adapt the pumping intensity of a pump of the dishwasher based on the estimated current rotational position of the wash arm.

A dishwashing machine is provided to include at least one spray part spraying washing water, a vane provided to be movable and deflecting the sprayed washing water, a rack accommodating tableware to be washed by the washing water deflected by the vane, a detection part detecting the tableware accommodated in the rack, and a controller generating position information with respect to the tableware detected by the detection part and controlling an operation of at least one of the at least one spray part and the vane based on the generated position information.

A warewash machine includes in-situ tank soil load reduction that involves at least one of: (i) prior to addition of fresh water, draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path until wash liquid level in the collection tank drops below a standard operating level, and thereafter adding fresh water; or (ii) draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path while simultaneously adding fresh water; or (iii) adding fresh water such that wash liquid level in the collection tank rises above a standard operating level, and thereafter carrying out draining of the collection tank.

Among other things, a method is disclosed which includes the following: acquiring at least one set of acceleration data indicative of a progression of measured acceleration values; determining status data indicative of a process step within a cleaning program performed by a dishwasher; outputting or causing the output of the determined status data. Further revealed is a device for executing and/or controlling this method, a system with one or more devices for executing and/or controlling this method and a computer program for executing and/or controlling this method by employing a processor.

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.

An appliance and method for determining an operational state of the appliance is provided. The appliance includes a cabinet, a flow device, and a sensor positioned at the cabinet. The cabinet includes a plurality of panels forming an interior volume at which a wash chamber is positioned. The flow device is configured to flow a fluid at the wash chamber. The sensor is positioned at the cabinet and configured to obtain sound vibrations from the wash chamber. The method includes obtaining, from the sensor, a signal during flow of a fluid at the wash chamber, and comparing the signal to a predetermined operational profile corresponding to operation of the flow device at the wash chamber to determine whether the flow device is operating properly.

Provided herein is an arrangement for a dishwasher for creating a wash zone with a selectable position within a washing chamber of the dishwasher. The arrangement may include a water spray arm rotatably arranged around an axis in the washing chamber, and a support element arranged to support the spray arm in the washing chamber. The support element may lock the spray arm in at least one position within the washing chamber. The arrangement may include a control unit arranged to control the operation of the dishwasher and a user interface for selecting the desired wash zone position within the washing chamber, and arranged to communicate the information to the control unit. The control unit may lock the support element in the selected position to create the wash zone. A dishwasher that includes the arrangement and a method for creating a wash zone with a selectable position are provided.

A household dishwasher appliance includes a wash tub with a sump, an electrically powered pump in fluid communication with the sump, a piezo microphone mechanically coupled to a portion of the wash tub, and a controller operatively coupled to the electrically powered pump and the piezo microphone. The controller is configured to operate the electrically powered pump to drain wash fluid from the sump, receive an audio signal from the piezo microphone, and diagnose a clog condition of a drain hose by analyzing the audio signal.
