A method of operating a dishwasher by controlling the use of hot liquids to dissolve fatty soils.

A dishwasher including a washing chamber to wash dishes, a sump concavely formed at a lower portion of the washing chamber to collect water used in washing, a microfilter disposed at the sump to filter out dirt produced when the dishes are washed, and an ultrasonic generator to radiate ultrasonic waves toward the microfilter. Since the microfilter is automatically cleaned by the ultrasonic generator, a user may not need to manually clean the microfilter.

A dishwasher with a tub at least partially defining a washing chamber, a liquid spraying system, a liquid recirculation circuit, and a liquid filtering system where the liquid filtering system includes a rotating filter and where a granular agent contacts the rotating filter to clean the filter. Methods of cleaning a rotating filter provided within a liquid flow by scouring the filter with a granular agent.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

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.

Proposed is a home appliance that includes a reception space configured to receive objects therein; a heater configured to heat the reception space; a door configured to open/close an open surface of the reception space, the door having a viewing window provided at the door; a lamp configured to illuminate an inside of the reception space; a sensor assembly configured to output a knock-on signal based on detecting a user's knock; and a controller configured to turn on/off the lamp based on the knock-on signal output by the sensor assembly, wherein based on a present state of the home appliance corresponding to at least any one of a plurality of preset exceptional situations, the controller is configured to not turn on/off the lamp regardless of the knock-on signal being output.

A system includes a dishwasher including a washing chamber, a sensor unit designed to detect a time curve of at least one sensor signal of a washing liquor and to output the detected time curve of the at least one sensor signal, a memory unit designed to store the time curve of the at least one sensor signal, an ascertaining unit designed to ascertain a temporal functional value based on the time curve of the at least one sensor signal, and a control device designed to carry out a washing program for washing washware in the washing chamber of the dishwasher and to carry out a specified action as a function of the temporal functional value.

A dishwasher includes in part a controllably-movable sprayer and a controller coupled to the controllably-movable sprayer and configured to control the controllably-movable sprayer to spray fluid onto one or more utensils disposed in a wash tub during a wash cycle. The controller is also configured to control the controllably-movable sprayer to spray fluid onto one or more walls of the wash tub by controllably-redirecting the controllably-movable sprayer to reorient one or more apertures of the sprayer away from the one or more utensils and towards the one or more walls.

A dishwasher with a tub at least partially defining a washing chamber, a liquid spraying system, a liquid recirculation circuit, and a liquid filtering system where the liquid filtering system includes a rotating filter and where a granular agent contacts the rotating filter to clean the filter. Methods of cleaning a rotating filter provided within a liquid flow by scouring the filter with a granular agent.

A dishwasher according to an embodiment of the disclosure may include: a cabinet; a tub disposed in the cabinet; a sump disposed below the tub; a deionizer comprising at least one electrode configured to produce soft water using raw water supplied from a water source, and supply the soft water to the sump; a plurality of flow paths including at least one pipe and/or at least one hose configured to allow the raw water, the soft water, and used water collected in the sump to flow; a plurality of valves disposed in each of the plurality of flow paths; and a controller including at least one processor, comprising processing circuitry, individually and/or collectively, configured to control the plurality of valves to allow the deionizer to be regenerated using the raw water or the used water, in at least one of a washing process or a rinsing process.
