Disclosed herein is a washing machine including a pump configured to selectively supply water to a circulation hose and a water discharge hose. The pump includes a pump motor configured to rotate forward and backward and a pump housing configured to form a space in which the impeller rotated by the pump motor is accommodated. The pump housing includes a supply port into which water discharged from the outer tub is introduced, a circulation water discharge port coupled to the other end of the circulation hose, and a water discharge port coupled to the water discharge hose. Furthermore, the pump housing includes a water discharge outlet and a circulation water outlet formed in a cylindrical direction in such a way as to be spaced apart from each other on a ring-shaped inside surface forming a clearance between the pump housing and the impeller.
