A dehydration control method of a drum washing machine includes accelerating a drum to a first rotational speed when a uniforming process is finished, measuring first eccentricity when the rotational speed of the drum reaches the first rotational speed, comparing the measured first eccentricity with a preset first reference eccentricity, storing the measured first eccentricity when the measured first eccentricity is less than the preset first reference eccentricity, accelerating the rotational speed of the drum to a second rotational speed and measuring a second eccentricity when the rotational speed reaches the second rotational speed, comparing the measured second eccentricity with the stored first measured eccentricity, and performing a dehydrating process when the measured second eccentricity is less than the stored first measured eccentricity.
