A method of controlling a washing machine with a drum rotatably provided in a tub that receives water, and a circulation pump that circulates water in the washing machine, the method including: rotating the drum in a first rotational direction by a first rotational amount during which laundry is raised on an inner circumferential surface of the drum by a centrifugal force; subsequent to rotating the drum by the first rotational amount, further rotating the drum by a second rotational amount in the first rotational direction during which the laundry falls from the inner circumferential surface of the drum; increasing a pump speed of the circulation pump while the drum is rotated by the first rotational amount in the first rotational direction; and decreasing the pump speed of the circulation pump while the drum is rotated by the second rotational amount in the first rotational direction.
