Whirlpool Dishwasher Water Inlet Valve Assembly WPW10158389

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Little or no water entering the tub during the fill step
• Slow or underfilling that leaves the dishwasher with an inadequate water level
• Humming or buzzing during fill with little or no water flow
• Water leaking from the valve body or inlet connection
• Poor cleaning performance associated with insufficient fill

Check Before Replacing

• Confirm the household water supply valve is fully open and the dishwasher supply line is not kinked.
• Observe whether water enters the tub during the fill portion of a cycle; do not assume the inlet valve is defective from this symptom alone.
• With electrical power and water supply safely disconnected, visually inspect the valve body, fittings, and supply-line connection for cracks, mineral deposits, or leakage.
• Inspect the valve inlet screen for visible debris without damaging or removing the screen.
• If safe test equipment and the appliance service procedure are available, compare the valve’s electrical test results with the model-specific service documentation.

Installation Notes

• Disconnect electrical power and shut off the dishwasher water supply before accessing the valve.

• Disconnect the water line and electrical connection only after the supply is secured, and retain any original mounting hardware or seals unless the model-specific instructions state otherwise.
• Reconnect the water line and wiring according to the appliance service instructions, then restore supplies and inspect the connection for leaks during a fill test.
• Verify the replacement against the dishwasher model and the removed part before installation.
