A method of controlling a washing machine comprising: a clothes amount detection operation of detecting an amount of clothes contained in a drum; a washing water supply operation of supplying washing water based on the detected amount of clothes; a washing operation of washing the clothes by applying current to a drive module for rotating the drum after the washing water supply operation; a rinsing operation of rinsing the clothes by supplying water to a tub from an external water source, after the washing operation; an unbalance water discharge operation of discharging the washing water contained in the tub such that a level of the washing water reaches an unbalance determination level, after the rinsing operation; an unbalance determination operation of determining unbalance of the clothes by applying current to the drive module while washing water is contained in the tub; a water discharge operation of discharging the washing water contained in the tub when the unbalance of the clothes is determined to be lower than the set value; and a dehydration operation of dehydrating the clothes to remove the washing water from the clothes, after the water discharge operation, characterized in: a clothes dispersion water supply operation of supplying washing water into the tub such that a level of the washing water reaches a clothes dispersing level, when the unbalance of the clothes is determined to be equal to or higher than a set value, wherein the clothes dispersing level is higher than the unbalance determination level and lower than a water level in the washing operation; a clothes dispersion operation of dispersing the clothes by controlling the current applied to the drive module after the clothes dispersion water supply operation, wherein, after the clothes dispersion operation, the controlling process is returned to the unbalance water discharge operation. a clothes amount detection operation of detecting an amount of clothes contained in a drum; a washing water supply operation of supplying washing water based on the detected amount of clothes; a washing operation of washing the clothes by applying current to a drive module for rotating the drum after the washing water supply operation; a rinsing operation of rinsing the clothes by supplying water to a tub from an external water source, after the washing operation; an unbalance water discharge operation of discharging the washing water contained in the tub such that a level of the washing water reaches an unbalance determination level, after the rinsing operation; an unbalance determination operation of determining unbalance of the clothes by applying current to the drive module while washing water is contained in the tub; a water discharge operation of discharging the washing water contained in the tub when the unbalance of the clothes is determined to be lower than the set value; and a dehydration operation of dehydrating the clothes to remove the washing water from the clothes, after the water discharge operation, characterized in: a clothes dispersion water supply operation of supplying washing water into the tub such that a level of the washing water reaches a clothes dispersing level, when the unbalance of the clothes is determined to be equal to or higher than a set value, wherein the clothes dispersing level is higher than the unbalance determination level and lower than a water level in the washing operation; a clothes dispersion operation of dispersing the clothes by controlling the current applied to the drive module after the clothes dispersion water supply operation, wherein, after the clothes dispersion operation, the controlling process is returned to the unbalance water discharge operation. a clothes dispersion water supply operation of supplying washing water into the tub such that a level of the washing water reaches a clothes dispersing level, when the unbalance of the clothes is determined to be equal to or higher than a set value, wherein the clothes dispersing level is higher than the unbalance determination level and lower than a water level in the washing operation; a clothes dispersion operation of dispersing the clothes by controlling the current applied to the drive module after the clothes dispersion water supply operation, wherein, after the clothes dispersion operation, the controlling process is returned to the unbalance water discharge operation.
