Abstract: PURPOSE: A washing machine and a control method thereof are provided to reduce noise and vibration by uniformly distributing laundries in a spin-drying process, thereby improving the performance of the washing machine and saving water. CONSTITUTION: A washing machine controlling method includes the following steps of: connecting a pulsator to a washing machine spindle of a motor (200); driving the motor in a normal direction at first balance RPM (202); counting time and determining whether a predetermined first period is passed or not (204); stopping the motor if the first period is passed (206); counting the time of the stoppage of the motor and determining whether a predetermined second period is passed or not (208); driving the motor at the first balance RPM in the reverse direction if the second period is passed; counting the time of the reverse driving the motor and determining whether the first period is passed or not (212); stopping the motor after the first period is passed (214) It determines whether it passed or not (216); counting the time of the stoppage of the motor and determining whether the second period is passed or not (218); and returning to the step of stopping the motor if the second period is not passed. [Reference numerals] (200) Connect a pulsator to a washing machine spindle of a motor; (202) Drive the motor in a normal direction at 600 RPM; (204,212) One hour elapses?; (206,214) Stop the motor; (208,216) Two hours elapse?; (210) Drive the motor in a reverse direction at 600 RPM; (218) Count the number (N) of motor rotation; (AA) Start; (BB,DD,FF,HH,JJ) No; (CC,EE,GG,II,KK) Yes; (LL) End
