Abstract: The present disclosure relates to a method for controlling a garment processing device, the method comprising: a foreign-material separating step of rotating a drum rotatably provided inside a tub that stores water such that friction occurs between garments inside the drum and the water; a drain step of discharging the water inside the tub to the outside of the tub; a first maintenance step of maintaining the rate of rotation of the drum, after same has reached a preconfigured first rate, at the first rate; a first measurement step of measuring the degree of imbalance occurring in the drum while the drum rotates at the first rate; a second maintenance step of increasing the rate of rotation of the drum to a predetermined second rate, if a first measured value measured in the first measurement step is equal to/below a preconfigured first reference value, and then maintaining same at the second rate; a second measurement step of measuring the degree of imbalance occurring in the drum while the drum rotates at the second rate; stopping the drum from rotating if a second measured value measured in the second measurement step is equal to/below a preconfigured second reference value; and a dewatering step of accelerating the drum to a third rate configured to be higher than the second rate, thereby removing water from the garments. The dewatering step is stopped if the degree of imbalance of the drum measured during the drum is accelerated to the third rate is larger than a predetermined imbalance reference value, and the imbalance reference value is configured on the basis of the second measured value.
