Understanding the Problem
What the inlet (fill) valve is and why it matters: The water inlet valve (also called the fill valve) controls cold and hot water flow into the washer. It has one or two solenoids that open when the machine requests water. When the valve fails it can cause no fill, slow fill, continuous filling, leaking at the back of the washer, or incorrect fill temperatures. Diagnostic and repair steps: 1. Verify the symptom — Observe whether the washer does not fill at all, fills slowly, overfills/continues filling, or leaks at the water connection. Note whether the problem happens on hot, cold or both. 2. Check the basics first — Confirm house water supply valves (behind the washer) are fully open. Inspect inlet hoses for kinks, collapse or low-flow. Remove hoses and briefly run water into a bucket to confirm good household pressure. 3. Inspect screens/strainers — Turn off water, remove the inlet hoses from the washer, and look for small screen filters in the valve inlets. Debris or mineral buildup often blocks flow. Clean screens with a brush and water. 4. Electrical checks (multimeter required) — Unplug the washer. Disconnect the wiring harness from the inlet valve. Test each solenoid coil for continuity: most read between about 500 and 2000 ohms (varies by valve). An open circuit (infinite ohms) indicates a failed coil. Also check the connector for 120VAC (or machine voltage) while starting a fill cycle (use caution or prefer a helper and insulated probes). If voltage is present but coil has no continuity, replace the valve. 5. Functional test — With water hoses reconnected, run a fill cycle. If the valve hums but water doesn’t flow, the valve is probably clogged internally or the diaphragm is ruptured and needs replacement. 6. Replace the valve if faulty — Typical replacement steps: a. Unplug washer and shut off water supply. b. Pull washer away from wall and remove top or back panel (model dependent). c. Place a towel to catch water, disconnect inlet hoses and electrical connectors (label wire positions). d. Remove mounting screws holding the valve assembly and pull it out. e. Transfer any rubber gaskets or fittings to the new valve if required. f. Install the new valve, reattach hoses and wiring, secure the panel, open water, and run a test cycle to confirm proper fill and no leaks. 7. Final checks — Check for any leaks at hose connections after pressurizing. Confirm proper water temperature selection and that the machine stops filling when the correct level is reached. Safety note: Always unplug the washer and shut off water before doing repairs. When checking live voltage use insulated test probes and extreme caution; if you are not comfortable testing live circuits, skip the live voltage check and rely on continuity and symptom testing or call a pro.
Common Symptoms
Washer won't fill or fills very slowly; only fills on one temperature (hot or cold); washer continuously fills or overfills; water leaking from back of washer at hose connections.
Common Causes
- Clogged or dirty inlet screens/filters blocking flow
- Burned-out or open solenoid coil(s) inside the valve
- Internal diaphragm failure or stuck valve plunger causing leaks/continuous fill

Helpful Repair Tip
Confirm a faulty inlet valve by unplugging the washer and measuring continuity on each solenoid; replace the valve if a coil reads open or if the valve receives voltage during a fill command but doesn't let water through.
Frequently Asked Questions
How much does it cost to replace the water inlet valve?
Parts typically cost between $35 and $120 depending on brand/OEM vs aftermarket. If you hire a technician, expect additional labor of about $100–$200 depending on rates in your area. Replacing the valve is usually a 30–60 minute DIY job if you are comfortable with basic tools.
Can I clean the inlet valve instead of replacing it?
If the symptom is low flow or no flow and you find clogged mesh screens, cleaning the screens can restore flow. However, if a solenoid coil has failed, a diaphragm is torn, or the valve stays open/closed, cleaning won't fix it — you'll need a new valve assembly.
