Possible Causes
Low household water pressure, Partially closed shutoff valve, Clogged inlet screen, Failed water inlet valve
How to Fix / Troubleshooting
Safety first: Turn off power and water before disconnecting hoses.
- Check water pressure: Ensure other faucets have strong flow. If household pressure is low, correct that first.
- Verify shutoff valve: Confirm the under-sink valve is fully open.
- Inspect and clean inlet screen: Disconnect the inlet hose at the dishwasher and clean the screen inside the valve.
- Check for kinks: Ensure the inlet hose is not kinked behind the dishwasher.
- Test fill: Restore water and power, start a cycle, and listen for water entering. If H2O persists and fill is weak or absent, replace the water inlet valve.
