Abstract: PURPOSE: A structure of valve for supplying water is provided to prevent water from being leaked in the water supplying passage of a dishwasher without controlling a first valve in the dishwasher having a water supply controlling line through a second electric valve while maintaining the characteristic of the first valve and connected to a fluid passage. CONSTITUTION: A dishwasher contains a water supplying valve, a controlling valve, a water supplying hose(14), and a flowing passage connected to a main body. Herein, the water supplying valve is opened while controlling the water supply by using the controlling valve. When a high water pressure is applied to the controlling valve, the pressure is concentrated to the water supplying hose, which connects the water supplying valve and the controlling valve. Thus, the water is leaked from the water supplying hose. Moreover, a load is applied to the controlling valve for causing an error in the operation of the controlling valve. And, the high water pressure is directly transferred to a machine for breaking inner components. Therefore, the water supply to the machine is blocked in the high water pressure state. Thus, the damage in the flowing passage and in the machine is prevented. Moreover, the amount of water through a regulator is adjusted while adjusting the water pressure in a water pipe to supply water to the machine at a certain pressure.
