Abstract
A washing machine is provided. The washing machine may include a circulation hose, a water discharge hose, and a pump configured to selectively supply water to the circulation hose and the water discharge hose. The pump may include a pump motor that is reversible and rotatable in a first direction and second direction, an impeller rotated by the pump motor, and a pump housing to provide a space in which the impeller is accommodated. The pump housing may include a supply port, a circulation water discharge port coupled to a second end of the circulation hose, and a water discharge port coupled to the water discharge hose. The water discharge outlet and the circulation water outlet may be arranged in a circumferential direction and spaced apart from each other on a ring-shaped inner surface of the pump housing.
