Whirlpool Dual Water Valve (WPW10420083)

The Whirlpool Dual Water Valve controls the flow of household water into your appliance. It uses two electrically operated valve sections to open and close water paths as the control sends power. This helps the appliance fill at the right time and stop filling when the correct level or timing is reached.

Common failures include mineral buildup that restricts the internal screens or valve passages, worn seals that allow leaking, and solenoids that weaken or fail so the valve does not open or close fully. Wiring issues at the terminals can also prevent the valve from responding to the control signal.

Look for these symptoms to help decide if this valve is the source of the problem:

• No water enters during a fill cycle, even though the water supply is on
• Slow filling or weak water flow that extends fill times
• Overfilling or water that continues to run when it should stop
• Water leaking from the valve body or at the inlet/outlet connections
• Intermittent filling that comes and goes during operation
• Buzzing or humming at the valve with little or no water flow
