Abstract: A dishwasher appliance and method of operation is provided. The dishwasher appliance may include a tub defining a wash chamber, a coarse filter disposed, a recirculation pump, and a drain pump. The method may include activating the recirculation pump to flow wash fluid through the coarse filter in a primary flow direction, and activating the drain pump to flow wash fluid through the coarse filter in the primary flow direction for an initial purge cycle. Further included may be flushing wash fluid through the coarse filter and into the tub in a secondary flow direction opposite from the primary flow direction. Still further included may be activating the recirculation pump to flow wash fluid through the coarse filter in the primary flow direction, and activating the drain pump to flow wash fluid through the coarse filter in the primary flow direction for an additional purge cycle.

Abstract: The invention proposes a dishwasher comprising a working chamber (2), comprising at least one spray arm (5, 6) which is arranged in a rotatable manner in the working chamber (2), and comprising a metering apparatus (9) for supplying and metering a substance, such as detergent, rinse aid etc., into the working chamber (2), wherein the metering apparatus (9) is designed as an insert part (9) comprising a housing (20, 21) for insertion into a recess in an inner wall (7) of the working chamber (2), for example in the door (7) of the warning chamber (2), and comprising a sensor unit (27, 28) for identifying a spray arm movement in the working chamber (2) of the dishwasher, which sensor unit is arranged at least partially in a housing (20, 21) of the metering apparatus (6), wherein the dishwasher has improved program control. According to the invention, this is achieved in that at least one inlet opening (17) in an interior (22) of the metering apparatus (9) is arranged at least partially in the jet (23) of water/liquid from a spray nozzle (24) of the spray arm (5, 6) during the rotation of the spray arm (5, 6), wherein the sensor unit (27, 28) is arranged at least partially in the/on the interior (22) and/or on a wall of the interior (22).

Abstract: A control method of a dishwasher that includes at least two flow paths having different flow rates, a chamber having communication holes that each communicate with a respective flow path, a water supply pump configured to supply washing water to the chamber through an impeller rotated by a motor, and a flow path switching unit located within the chamber and configured to sequentially open the communication holes is described. The control method includes the actions of measuring an amount of current supplied to the motor while the motor rotates the impeller to supply washing water to the chamber, and determining a position of the flow path switching unit by comparing the amount of current supplied to the motor with reference current amounts that are each designated as an amount of current supplied to the motor when the motor rotates the impeller to supply washing water to the respective flow path.
