Abstract: A method for controlling a washing machine supplying water to at least a portion of the drum in the tub, performing a first operation in which the water contained in the tub is heated by operating a heater and the drum is rotated at a first set speed, draining the tub, supplying water to submerge at least a portion of the drum in the tub, and performing a second operation for heating the water in the tub by the heater and rotating the drum. The second operation includes rotating the drum at a second set speed lower than the first set speed, and repeating a first drum cleaning operation in which the drum is rotated at a third set speed lower than the second set speed, and a second drum cleaning operation in which the drum is rotated at a fourth set speed lower than the third set speed.
