Abstract: A method of controlling a washing machine includes detecting a water level in a drum when a barrel cleaning is executed; supplying or draining water according to the detected water level such that a water level reaches a reference water level; soaking an interior of the drum in water; draining water after the interior of the drum is soaked in water; and detecting clothes contained in the drum by rotating the drum.

Abstract: A washing machine and a control method thereof, capable of reducing noise by performing a zero-current control during the braking of a motor, and checking whether a vibration sensor is installed on a tub in a weight detection state in the beginning of a spin-drying. The zero-current control is performed by driving a current regulator with a command current set to “0 A”, so that the current flowing at the motor decreases and thus noise is reduced. In a washing machine having a vibration sensor fixedly attached to a tub, a fixation state of the vibration sensor with respect to the tub is checked in advance by use of measurement data of the vibration sensor at a weight detection stage in the beginning of the spin drying so that the frame touch caused by an erroneous detection of vibration or a failure of vibration detection may be prevented.
