As, through the washing operation input part, a washing driving signal is inputted, the washing procedure is performed, controlling the water level sensing part and the motor drive part, then, in compliance with a certain program, the dewatering procedure is started. Thus, a microcomputer senses the rotation number of the dewatering motor in the procedure of dewatering by the rotation number sensing part for inputting into the microcomputer, judging the delivery of the rotation number is within the range of the preset dewatering, if judged it is not the number of the dewatering range which is preset, the rotation number sensing part determines whether it is the same or over the rotation number on the loadless. At this time, when it is the same or over, the microcomputer sends the alarm to inform the dewatering motor has a problem.
