ABSTRACT:
A washing machine includes a rotatable tub in which an agitator is disposed. A tub shaft connected to the rotatable tub is mounted on a base for rotation. A clutch is mounted on the tub shaft to be reciprocally moved so that the clutch engages a clutch engagement hole of the base and an engagement protrusion of a motor rotor alternately. An operation lever mounted on the base is operated so that the clutch is reciprocally moved. The bottom of the base includes a region of rotational locus of the clutch. The region is flat except for the clutch engagement hole so that the clutch is prevented from engaging a portion other than the clutch engagement hole. A reed switch is mounted on the base to be turned on when detecting engagement of the clutch with the clutch engagement hole. A control device proceeds from a dehydration stage to a next stage only when the reed switch is turned on. When the reed switch is not turned on, the rotatable tub is rotated at a low speed with the operation lever being maintained in the operable state, so that an operation for engaging the clutch with the clutch engagement hole is re-executed.
