Abstract: A method of controlling a washing machine that includes a tub, a drum rotatably disposed in the tub, at least one nozzle spraying water into the drum, a washing motor rotating the drum relative to the tub, and a circulation pump circulating water discharged from the tub, the method including: rotating the drum to cause laundry in the drum (i) to be raised with respect to a bottom of the drum and (ii) to fall downwards into the drum while water is supplied to the drum; spraying water through the at least one nozzle while the drum rotates; based on a first water level in the tub, controlling the circulation pump to rotate at a first rotation speed; supplying water to the drum to increase the water in the tub to a second water level; and controlling the circulation pump to rotate at a second rotation speed.

Abstract: A method of controlling a washing machine. The washing machine includes a tub with an entry hole configured to receive laundry, a drum rotatably disposed in the tub, a ring-shaped gasket disposed along a circumference of the entry hole of the tub, a pump configured to circulate water that is discharged from the tub, and at least one circulation nozzle provided in the gasket and configured to spray the water that is circulated by the pump into the drum. The method includes: supplying water into the tub; rotating the drum; accelerating a pump speed of the pump while the drum rotates; and based on the pump speed of the pump reaching a threshold speed during the acceleration of the pump, opening a spray valve of the washing machine such that water supplied from an external water source is sprayed into the drum through a direct water nozzle.

Abstract: A method of controlling a washing machine includes: sensing a laundry amount accommodated in a drum; performing water supply into the drum according to the sensed laundry amount; rotating a pump motor at a certain initial rotation speed and transferring washing water discharged from the drum to at least one nozzle for spraying water into the drum; sensing a water level in the drum; performing a re-supply of water at least once until the sensed water level reaches a set water level; and increasing the rotation speed of the pump motor whenever the re-supply of water is performed, so that as the rotation speed of the pump motor is increased, the reaching range of the water stream sprayed through the nozzle gradually expands from the lower side of the circumferential surface of the drum to the rear surface of the drum.
