    Abstract: The present disclosure relates to a dishwasher. The dishwasher according to an embodiment comprises: a tub having a washing room, in which an object to be washed is accommodated, formed therein; a nozzle which is arranged in the washing room and sprays washing water to the object to be washed, and includes a magnetic body at one end thereof; a coil which his formed to surround a region corresponding to a movable range of the nozzle, and through which an electric current flows according to the rotation of the nozzle; and a controller which controls an operation of the nozzle according to an operation command, and determines an operating status of the nozzle on the basis of a value of the voltage generated in the coil.

    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.
