Compatible With Major Brands Comes in Supplying Demand packaging. Monitors and controls the amount of water entering the washing machine's tub during the various wash cycles. Operates based on air pressure created by the presence of water in the tub - As the water level increases, it creates more pressure in an air chamber or tube connected to the pressure switch. When the desired water level is reached based on the preset cycle requirements, the increased air pressure triggers the switch to stop the water inlet valve from filling the tub further.
