A dishwasher is proposed. The dishwasher includes a case accommodating a cleaning target therein, a sump connected to an interior of the case to collect wash water, a wash pump into which the wash water flows from the sump, and generating steam, a steam nozzle into which the steam flows from the wash pump, and spraying the steam into the case, and a bubble filter disposed on a steam path between the wash pump and the steam nozzle to remove a bubble in the steam path.
