Abstract: The present disclosure relates to a dishwasher. The dishwasher of one embodiment comprises a tub having a wash space in which a wash target is accommodated, a sump being disposed at a lower end of the tub and storing wash water, a wash pump supplying wash water that is accommodated in the sump to a nozzle, a rack being disposed in the wash space and storing a wash target, a nozzle being disposed at a lower end of the rack, being rotated by a repulsive force of wash water that is supplied from the wash pump, spraying wash water to a wash target, and having one end to which a magnetic object is coupled, a sensing module being disposed in an area that corresponds to a range in which the nozzle operates and comprising a Hall sensor 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 whether the nozzle rotates, a rotation speed of the nozzle and a rotation direction of the nozzle, based on the sensing results, to output an abnormality notification to a user or control wash water that is supplied to the nozzle through the wash pump.

Abstract: The dishwasher of one embodiment comprises a tub, a sump, a wash pump, a rack, a nozzle disposed at a lower end of the rack, rotated by a repulsive force of wash water supplied from the wash pump, spraying wash water to a wash target, 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 generated by a rotation of the nozzle, 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 and whether the nozzle rotates, to output an abnormality notification to a user or control wash water supplied to the nozzle through the wash pump.
