The water is put into the water tank(4), the start key is inputted, microprocessor(30) detects the weight of the laundry and decides the required water level. Next the water level sensing part(16) operates the water supply drive part(24) to perform supply until the signal of a high potential is inputted, and when deciding the weight sensing part(14) and the level sensing part(6) are out of order, the water tank is reverse rotating a number of times, checking if the signal of the high potential is inputted from the photo-transistor which is one step above the water level set.
