Since the water is heated again by the heater and supplied into the coffee basket via the switching valve, there is a difference between the temperature of the hot water in the water tank at the time it is sensed and the temperature of the hot water actually supplied inside the coffee bath. Therefore, there was a drawback that hot water at the optimum temperature was not supplied into the coffee basket.
