An apparatus and method control dewatering in a drum-type washer so that a dewatering cycle can be selectively modified by a user selection and so that noise and vibration on a dewatering cycle can be reduced. the apparatus includes a key input for selecting a wash course, the selected wash course corresponding to one of a plurality of selectable dewatering courses; memory for storing at least one eccentricity detection reference value per the selectable dewatering course; and a controller for performing the selected wash course based on the stored at least one eccentricity detection reference value. The method includes selecting a wash course, the selected wash course corresponding to one of a plurality of selectable dewatering courses; storing in memory at least one eccentricity detection reference value per the selectable dewatering course; and performing the selected wash course based on the stored at least one eccentricity detection reference value.
