Product Description

The Whirlpool WP8578340 Inlet Valve is used to regulate the water supply of the washer. This controls the flow of hot and cold water during wash cycle and other cycles that may be set for the appliance. This is because the solenoid controls the opening and closing of the water valves to enable the right water temperature and level to be attained. The valve is designed to be durable, providing a longevity to the problem of water intake, leakage, and flooding.
