Whirlpool OEM washer water inlet valve and inlet assembly with hot- and cold-water valves, vacuum break, and thermistor for water-temperature sensing. A defective valve may cause slow filling or failure to fill.

Is This the Right Part?

Common Symptoms

• Washer does not receive hot or cold water
• Washer fills slowly
• Water leaks at the inlet-valve assembly
• Water-temperature control or mixing may be incorrect
• Washer may continue filling if the valve does not close properly

Check Before Replacing

• Confirm both household hot- and cold-water supply valves are fully open.
• Check the inlet hoses for kinks, crushed sections, or blocked screens before condemning the valve.
• With the washer unplugged, inspect the valve body, hose connections, wiring connectors, and thermistor wiring for visible cracks, corrosion, looseness, or damage.
• If a fill problem is present, compare the affected hot/cold supply and check whether water enters only when the washer’s controls call for filling; do not bypass safety controls.
• After any inspection, restore water and power cautiously and check for leaks before normal operation.
