A method for improving cleaning performance of a dishwashing appliance includes implementing, via a computer application, a filter cleaning process for a filter assembly of the dishwashing appliance. The filter assembly is positioned at least partially in a sump in a bottom wall of the dishwashing appliance. The filter cleaning process includes prompting a user to remove the filter assembly from the dishwashing appliance. Further, the filter cleaning process includes initiating the dishwashing appliance to fill and drain the dishwashing appliance for a predetermined time period to flush the dishwashing appliance of residual particles remaining in the sump. Moreover, once the filling and draining is complete, the filter cleaning process includes prompting the user to reinstall the filter assembly in the dishwashing appliance.

A method of cleaning a washing machine and components and systems for enabling a user to clean the washing machine are provided. The method includes gaining access to debris that is trapped in otherwise inaccessible and/or concealed areas and/or directing debris out of inaccessible and/or concealed areas. The components include a jet channel that selectively couples to a discharge manifold in use and is removable to provide access to an interior area of the discharge manifold for cleaning. The systems include a removable mount assembly for accessories and a purging system for pumps and other concealed areas. The purging system is configured to discharge purging fluid through a plurality of purging ports and into concealed areas so as to direct debris in the concealed areas out of the concealed areas.

Systems and/or methods for the monitoring and/or control of thermal sanitization in automated cleaning machines are described. A cleaning machine controller may predict a number of heat unit equivalents that will be delivered during a cleaning process based on a sump temperature difference (i.e., a change in the temperature of the cleaning solution in the sump) experienced at or near the beginning of the cleaning process. One or more cleaning process parameters may be adjusted and/or controlled based on the sump temperature difference in order to ensure that a target number of heat unit equivalents are delivered in order to achieve thermal sanitization of the wares subjected to the cleaning process.

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 warewasher includes at least one washing system configured as a recirculation loop, wherein the washing system includes a nozzle system having at least one washing nozzle for spraying washing liquid onto washware, a washing tank for collecting at least a portion of the sprayed washing liquid, and a washing pump for feeding washing liquid collected in the washing tank to the at least one washing nozzle. A tank cleaning system has at least one cleaning nozzle arranged in or on the washing tank in such a way that, as needed and/or at the end of a washing shift or washing day of the warewasher, a cleaning liquid can be sprayed inside the washing tank or can be sprayed into the washing tank via the at least one cleaning nozzle of the tank cleaning system for cleaning the washing tank and/or components accommodated in the washing tank.
