The invention relates to a dewatering control method for a roller washing machine. The dewatering control method includes a distribution detecting step and a dewatering step. The distribution detecting step includes that an eccentric value is divided into a plurality of gears, and during distribution, the gears are tried from low gears to high gears. If an actual eccentric value falls at a certain gear, low-speed dewatering is conducted, after a part of water is removed, an eccentric value is detected, and if the eccentric value still falls at the gear, medium-speed dewatering is conducted, otherwise, distribution is conducted again. Eccentric value detecting is also conducted during medium-speed dewatering, and if gears of an eccentric value are the same, final dewatering is conducted, otherwise, distribution is conducted again. During dewatering, low-speed dewatering and medium-speed dewatering are conducted first, eccentric value detecting is conducted, and final dewatering speed is relevant to the gears, and therefore, vibration of the washing machine can be fully reduced, noise is reduced, and box body collision can be avoided. Load with poor balancing performance is distributed at a high gear, dewatering at the set rotating speed is conducted, distribution detecting time can be effectively reduced, and power consumption and dewatering time can be effectively reduced.
