A dish washing machine having a structure allowing water to be evenly ejected onto the interior of a washing tub. The dish washing machine includes a cabinet forming an external appearance of the dish washing machine, a washing tub arranged in the cabinet and allowing dishes to be washed therein, a dish basket arranged in the washing tub, at least one liquid ejection unit arranged in the washing tub to eject water, a defection unit arranged facing the liquid ejection unit to deflect the water ejected from the liquid ejection unit toward the dish basket, and a drive unit to drive the defection unit to be moved within the washing tub. Since the dish washing machine includes a defection unit in addition to a liquid ejection unit, a dead zone which water does not reach may be eliminated and divided and intensive washing may be possible in the washing tub.
