Abstract
A washing machine includes: a cabinet; a tub; a pump for discharging washing water received in the tub to an outside of the tub; and a valve assembly for introducing washing water discharged from the pump. The valve assembly includes: a valve housing; a first chamber defined inside the valve housing and configured to connect to a circulation flow path for sending washing water introduced from the pump to the tub and a drainage flow path for draining washing water introduced through the pump to an outside of the cabinet; a disc valve configured to linearly move in a vertical direction inside the first chamber and move upward by a pressure of washing water discharged from the pump; and a weight part disposed above the disc valve and configured to apply a load to the disc valve.
