Abstract
A method for controlling a dishwasher includes: supplying washing water to a sump; rotating an impeller disposed in a washing pump by a washing motor so that the washing water flows into the washing pump from the sump;operating a heater disposed in the washing pump so as to heat the washing water existing in the washing pump and generate steam to supply to a steam nozzle; and supplying the washing water or steam in the washing pump to the steam nozzle by rotating the impeller at a second set rotational speed lower than a first set rotational speed by the washing motor. The method further includes closing a selector valve, configured to open and close a path between the washing pump and the steam nozzle, when the impeller rotates at the first set rotational speed or higher.
