CONSTITUTION: A wash passage control device of a dishwasher comprises a motor(101) for controlling washing injection force; a pump(110) discharging wash water by rotating by the motor; a passage control valve(120) installed to a branch passage(113) communicating with a discharge passage(112) of the pump; and a rotation control unit for controlling rotation of the passage control valve by a washing method decided according to the washing volume. The passage control valve has at least two inlets and outlets(125,126). The passage control valve receives wash water discharged by the pump and discharges the wash water to discharge passages(141,142) of a lower arm and/or an upper arm.
