ABSTRACT OF THE DISCLOSURE A washing machine comprises a tub, in which a pul- sator is rotatably arranged. The pulsator is driven by a motor positively or reversely. When a start switch is pressed, first an initial cycle is started for a relatively short period of time to dissolve detergents. When this initial cycle is completed, a main cycle is startled, during which the pulsator repeats positive and reverse rotations with intervals. The main cycle is arranged to continue for a set period of time, into which auxiliary cycles shorter than the main cycle are intermittently inserted. The positive and reverse rotation times of adjoining repeating units included in the main cycle differ from each other. In the auxiliary cycle, its repeating unit involves a relatively longer ro- tating time or a shorter recess time of the pulsator as com- pared with the repeating unit constituting the main cycle. Accordingly, during the auxiliary cycle, a water current stronger than that in the main cycle is produced, thus re- ducing clothes entanglement during a washing process, without undue deterioration in performance.
