An appliance and method for operating an appliance is provided. The appliance includes a pump configured to flow a volume of fluid, a flow nozzle configured to eject the fluid provided from the pump, and a motor configured to selectively operate the pump to flow the fluid through the flow nozzle. The method includes acquiring a dataset including a function of current magnitude and time corresponding to operation of a pump to flow a volume of fluid; determining an average current magnitude based at least on the dataset; determining a standard deviation based at least on the average current magnitude; comparing the standard deviation to a threshold to determine whether to transmit a control command based.

A household dishwasher includes a washware receptacle, a holding facility positioned in or on the washware receptacle to hold washware, an actively driven spray arm, and an open-loop and closed-loop control facility designed to influence a rotational movement of the spray arm as a function of a position of the holding facility in or on the washware receptacle so that the spray arm pauses close to the holding facility to apply wash liquor and/or fresh water to the washware held by the holding facility.

A method of operating a dishwashing appliance includes receiving, at an external device, an input indicative of a characterization of a load of items inside an other appliance and determining a change in the characterization the load of items inside the other appliance based on the received input. The method also includes operating a wash cycle of the dishwashing appliance in response to the change in the characterization of the load of items inside the other appliance.

A method of determining calcification of at least a portion of a water heating assembly in a home appliance having a treating chamber. The method includes supplying heated water to the treating chamber via the water heating assembly. The water heating assembly includes a heating element that is selectively energized. A number of thermostat trips are sensed during at least a portion of a cycle of operation. A water temperature value indicative of a water temperature can be sensed. A calcification level of the heating element or the at least a portion of the water heating assembly can be determined based on the number of thermostat trips and the water temperature value.

A dishwasher includes a tub, a sump, a wash pump, a rack, a nozzle disposed at a lower end of the rack, the nozzle being rotated by a force of wash water supplied from the wash pump and having a magnetic object coupled to one end of the nozzle so that a first pole and a second pole of the magnetic object face a rotation direction of the nozzle, a sensing module that senses a magnetic force generated by the magnetic object, and a controller receiving sensing results from the sensing module, and determining one or more of a rotation direction of the nozzle, a rotation speed of the nozzle, or whether the nozzle rotates, to output an abnormality notification to a user or control wash water supplied to the nozzle through the wash pump.

A dishwashing apparatus may include a sump. The sump may include a sump pan configured to couple with a wash chamber of the dishwashing apparatus. The sump may include a sump well coupled to the sump pan and configured to collect the liquid from the sump pan. The sump well may include a well inlet in communication with the sump pan. The sump pan may convey the liquid to the well inlet. A recirculation port extending through a first wall of the sump well. A drain port may extend through a second wall of the sump well. The second wall defines a bottom of the sump well. The dishwashing apparatus may include a controller. The controller may monitor electrical characteristics of a pump. The controller may provide a notification if fluid is not flowing through the pump.

A dishwasher appliance includes a door pivotally providing selective access to the wash chamber and a venting system comprising a first fan for urging chamber air from the wash chamber and a second fan for urging ambient air, wherein the chamber air and the ambient air mix to create a mixed flow of air that is discharged from the dishwasher appliance. A controller is configured to energize the first fan and the second fan, monitor a power draw by the first fan and the second fan, determine that the venting system has malfunctioned based at least in part on the power draw by the first fan and the second fan, and implement a responsive action in response to determining that the venting system has malfunctioned based at least in part on the power draw.

A method of determining calcification of at least a portion of a water heating assembly in a home appliance having a treating chamber. The method includes supplying heated water to the treating chamber via the water heating assembly. The water heating assembly includes a heating element that is selectively energized. A number of thermostat trips are sensed during at least a portion of a cycle of operation. A water temperature value indicative of a water temperature can be sensed. A calcification level of the heating element or the at least a portion of the water heating assembly can be determined based on the number of thermostat trips and the water temperature value.

A dishwasher may utilize personalized utensil detection to detect the utensils regularly washed by the dishwasher, in part based upon training of a personalized machine learning model used in personalized utensil detection. One or more scanning aids may also be used to provide a common frame of reference when capturing images of utensils used to train the personalized machine learning model.
