When it is detected that the motor for rotating the agitator of the machine is locked, the motor is turned in the forward direction and/or in the reverse direction a predetermined number of times. If the motor is still locked, an indicating unit is operated to indicate the occurrence of the abnormal condition. When the motor locked by an excessively large quantity of wash and the motor is not unlocked after the motor is turned in the opposite direction, the occurrence of the abnormal condition is indicated by an alarm unit. Therefore, the operator, informed of the presence of the abnormal condition immediately upon its occurrence, can rectify the problem, for instance, by decreasing the size of the washing load.
