Is connected to the base of the washer's outer tub with a clear rubber tube that carries air that increases in pressure as the water level in the washtub increases. THE FUNCTION OF EACH PARTWater ValveAll washing machines have an internal water valve that connects to the water supply of your home and automatically controls hot and cold water to flow into the tub by opening an internal gate with several electromagnetic solenoids, also called coils. www.themegallery.comwww.themegallery.comDesigned by Guild Design Inc.All washers have a drain pump to force the dirty water up and out of the washer tub.PumpDesign by group one of the DDT1111's class
