A washing machine comprises a tub, in which a pulsator 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 started, 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 positively and reversely rotating times of the adjoining repeating units included in the main cycle differ with each other. In the auxiliary cycle, its repeating unit involves a relatively longer rotating time or a shorter recess time of the pulsator as compared 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 restraining the "entangling clothes" during a washing process. |
