The invention discloses a washing machine and a control method for the washing machine. The washing machine comprises a filtering draining device and a control device, wherein the filtering draining device comprises a water inlet, a filtering component, a draining component and a circulating component; the filtering component is arranged between the water inlet and the circulating component and is used for supplying the washing water after being filtered to the circulating component; the draining component is arranged along a tangential direction of a filtering surface of the filtering component; the control device is respectively connected with the draining component and the circulating component; the control device is used for controlling the running of the washing machine, acquiring the running stage of the washing machine and controlling the draining component and the circulating component according to the running stage of the washing machine. Thus, when the circulating component works, the washing water flows by the filtering component from top to bottom, so that the circulating water free from impurities like soft flocks can be guaranteed and the washing effect in the washing machine can be guaranteed. When the draining component works, the draining water can flow along the tangential direction of the filtering component and can take away the impurities like soft flocks accumulated on the surface, so that the self-cleaning effect can be achieved.
