A dishwasher appliance includes a circulation pump, a pressure sensor upstream of the circulation pump, and a diverter downstream of the circulation pump. A method of circulating fluid includes operating the circulation pump at a first speed less than a target speed for a first amount of time. The method also includes determining a first minimum pressure value based on the first speed and a position of the diverter and monitoring a pressure upstream of the circulation pump with the pressure sensor. The method further includes operating the circulation pump at a second speed greater than the first speed when the monitored pressure continuously exceeds the first minimum pressure value for a second amount of time and determining a second minimum pressure value based on the second speed and the position of the diverter after operating the circulation pump at the second speed for a third amount of time.

A dishwasher appliance that includes features for prevention and detection of flood events and leaks without sacrificing performance or efficiency of the dishwasher appliance is provided. Moreover, methods for detecting and preventing such flood events and leaks are also provided.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A dishwashing appliance, including methods of operation, is provided. The dishwashing appliance may define a vertical direction and include a tub, a base conductivity sensor mounted at a first level within the tub, and an elevated conductivity sensor mounted at a second level within the tub, the second level being higher along the vertical direction than the first level.

A method of operating a dishwasher appliance includes initiating a wash cycle of the dishwasher appliance. The wash cycle includes operating the dishwasher appliance in a wash mode for a first predetermined amount of time by positioning a diverter in a first position to direct a fluid flow to a spray assembly of the dishwasher appliance. The method also includes positioning the diverter in a second position to direct the fluid flow to a filter cleaning manifold for a second predetermined amount of time. The method further includes sensing the second position of the diverter with a position sensor. The method further includes performing a predetermined action after the second predetermined amount of time when the second position of the diverter is sensed before the first predetermined amount of time has elapsed.

A dishwasher appliance that includes features that allow for prevention and detection of flood events or tub overfills without sacrificing performance or efficiency of the dishwasher appliance is provided. Moreover, methods for detecting and preventing such flood events are also provided.

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 dish washer effectively identifies a viscosity of a detergent stored in a detergent supply based on the number of revolutions of a roller sensed via a roller sensor and an operating time of a pump motor, thereby simplifying a structure, improving space utilization, and reducing a manufacturing cost as a separate electrode sensor or level sensor for identifying the viscosity of the detergent is eliminated.

A dispensing assembly including at least one treating chemistry container configured to store a treating chemistry and selectively fluidly coupled to the treating chamber, a sensor configured to detect a characteristic of the dispensing assembly and output a first signal based thereon, an illumination detector outputting a second signal indicative of ambient illumination and an indicator outputting a human-detectable signal.
