Abstract: A method of controlling a washing machine. The washing machine includes a tub configured to receive water, a drum rotatably disposed in the tub, a volute pump including (i) an impeller configured to rotate in one or more directions to pump water discharged from the tub and (ii) a pump housing that defines a volute-shaped passage configured to guide water pumped by the impeller, and a circulating water supply device configured to supply water discharged from an outlet port of the volute pump into the drum. The method includes: supplying water and detergent into the tub; and rotating the impeller of the volute pump in a first direction to discharge a first amount of water from the volute pump, the first amount of water being less than a second amount of water discharged from the volute pump based on the impeller being rotated in a second direction.

Abstract: A front-loading washing machine and a control method therefor are disclosed. The control method includes: when a sensed amount of laundry in a drum is equal to or less than a preset amount, rubbing step at which the drum is rotated in both directions, wherein the rubbing step comprises: a first rotation step at which the drum is rotated in a first direction by a preset one-direction rotational angle; and a second rotation step at which the drum is rotated by the one-direction rotational angle in a second direction opposite to the first direction, and wherein the first rotation step and the second rotation step are performed alternately and repeatedly. Accordingly, it is possible to perform a washing motion which improves washing performance and reduces wear and tear of the laundry.
