Possible Causes
Failed water inlet valve coil, Clogged inlet screen, Low household water pressure, Kinked or closed supply line
How to Fix / Troubleshooting
Safety First: Turn off power and shut off the dishwasher water supply valve under the sink.
- Verify water supply: Ensure the shutoff valve is fully open and the supply hose is not kinked.
- Clean inlet screen: Remove the toe-kick panel, locate the water inlet valve (usually front left), disconnect the supply line, and inspect the valve screen for debris. Clean gently with a small brush.
- Check valve coil: With power off, disconnect the electrical connector and test the valve coil resistance with a multimeter (typically 500–1500 ohms). An open reading indicates a bad valve.
- Replace valve if needed: If the coil is open or the valve is mechanically stuck, replace the water inlet valve with the correct Whirlpool OEM part.
