Abstract
A main motor is rotated at a predetermined target speed to determine whether a clutch has been normally operated during switching between a spin mode and an agitation mode. A current value sensed during rotation of the main motor is compared with a predetermined reference value to determine whether the clutch is normally operated. Mode switching is performed or the clutch is re-operated based on the determination result, thereby correctly performing switching between the spin mode and the agitation mode.
