Understanding the Problem
The dishwasher inlet (fill) valve controls water entry from your home's supply into the dishwasher. When the inlet assembly or its screens, hoses, or solenoids fail, the machine can refuse to fill, fill slowly, overfill, or leak at the base. Common failure modes include a stuck solenoid, clogged inlet screen, damaged inlet hose, or a failed float/pressure sensor that misreports water level. Diagnosing inlet problems requires checking both the water supply and the appliance components. Confirm the home shutoff is open and supplying normal pressure, then inspect the inlet hose, valve and screen for debris, test the solenoid for continuity and proper voltage, and check the float/float switch or water-level sensor. Replacing the failed inlet valve or cleaning/replacing the inlet screen/hose resolves the majority of issues.
Common Symptoms
Dishwasher won’t fill at all, fills very slowly, runs continuously filling/draining, overfills, or there is water leaking near the base/kickplate.
Common Causes
- Failed inlet (solenoid) valve — electrical coil burned out or valve stuck
- Clogged or dirty inlet screen/strainer restricting flow
- Kinked or damaged water supply/inlet hose or loose fittings
- Faulty door latch/float switch or pressure sensor incorrectly detecting water level
- Control board or timer failing to send voltage to the inlet valve

Helpful Repair Tip
Turn off water and power, remove the lower kickplate, and inspect the inlet valve screen for debris; if cleaning doesn’t restore normal fill, test the valve coil for continuity with a multimeter (typical coil continuity is 500–1500 ohms).
Frequently Asked Questions
How do I test if the inlet valve is bad?
Disconnect power and water. Access the valve at the base/kickplate. Visually inspect the valve and screen for debris. Use a multimeter to check the valve coil for continuity (consult your model’s spec — many read roughly 500–1500 ohms). With power restored and a helper, you can also start a fill cycle and verify the valve receives 120V (or model voltage) at the terminals when it should open. No voltage means an electrical/control issue; voltage present but valve not opening indicates a bad valve.
Can I replace the inlet valve myself and how much will it cost?
Yes — replacing an inlet valve is a common DIY job if you’re comfortable turning off water and power and working under the sink/kickplate. Typical time: 30–60 minutes. Parts cost varies by brand and whether you buy OEM or aftermarket (typically $30–$120). If you’re uncertain about electrical testing or access is difficult, hire a technician — labor adds $100–$250 depending on region.
