Dishwashing machine comprising: a controller; a spray arm assembly comprising a spray arm having one or more spray holes for spraying a washing load with water, and a pipe for delivering water to the spray arm; a pump for pumping water through the pipe and to the spray arm; the pipe being constructed and arranged to at least partially restrict flow of water from the pump to at least a part of the spray arm dependent on spray arm orientation relative to the pipe, a power consumption of the pump thereby being dependent at least in part on the spray arm orientation relative to the pipe; and the controller being configured to monitor the power consumption of the pump in order to determine rotational information of the 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 warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A dishwasher includes a memory unit for storing a number of washing programs, a control device configured to carry out a washing program from the number of washing programs; and a communication unit configured to retrieve a specific washing program from an external device in accordance with a status information relating to an external household appliance, and to store the retrieved specific washing program in the memory unit, said control device carrying out the stored specific washing program.

In a method for controlling a dishwasher, a user preference is captured for a cleaning cycle of the dishwasher. Parameters associated with a cleaning cycle of the dishwasher are read over a plurality of cleaning cycles, and a user input that indicates satisfaction by the user with one of the cleaning cycles is captured. An optimization is determined of a parameter of the parameters on the basis of the user input and the user preference.

A method for the dosing of cleaning agents in cleaning machines includes the steps: receiving the control information items; wherein the control information items are dependent on an information item about a cleaning machine; determining the progress of a cleaning operation; dosing of cleaning agent depending on the received control information items and the determined progress of the cleaning operation; wherein the information item about the cleaning machine can be manually input via a user interface.

A dishwasher can be included in a home network and can be utilized to complete a cycle of operation. The dishwasher includes a controller capable of automatically determining treating at least one cycle parameter based on the communication of at least one aspect of a recipe. The at least one aspect of a recipe can be wirelessly provided to a computer system that is in communication with the dishwasher. The computer system can be the controller or any known computer system in communication with the dishwasher.

A method of operating an appliance including determining user satisfaction with an operation cycle, adjusting at least one operational parameter of the cycle based on the user satisfaction, and incorporating the adjusted operational parameter into a subsequent cycle is disclosed along with the apparatus including a processor configured to perform the method.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A household appliance for treating objects has a control device and an operating device being a touchscreen. First and second adjustable control variables are displayed as flat touch-sensitive operating elements that are separated from each other on the touchscreen on at least two screen displays of different hierarchy. First adjustable control variables are treatment programs and second control variables are program parameters associated with the treatment programs. First operating elements are displayed on a hierarchically higher screen display with a hierarchy and are associated with treatment programs which are selected by touching an associated operating element. Second operating elements are displayed on hierarchically lower screen display and enable the program parameters to be adjusted. The hierarchically lower screen display follows the hierarchically higher screen display if a first operating element is selected by touch. The second operating elements have elongated sensor elements for adjusting the associated parameter value by touch.
