Abstract
A control method for a washing machine includes: a mode change step in which the configuration of a coupler is moved by operating a solenoid module in such a way that a drive shaft for spinning a pulsator and a dewatering shaft for spinning a washing tub are axially coupled or decoupled; and a mode check step in which a drive motor for rotating the drive shaft is operated and the load of current outputted to the drive motor is sensed, the mode check step comprising a coupler setting step in which, if the load of current outputted to the drive motor does not satisfy a set load value, the solenoid module is operated to reposition the coupler.
