Understanding the Problem
The water inlet valve controls water flow into the washer. When it fails you can get no water, slow fill, continuous filling, water leaking from the back, or the washer only fills on one temperature (hot or cold). Below are step-by-step diagnostics and repair instructions so you can confirm the inlet valve is bad and replace it safely. 1) Safety first: Unplug the washer and shut off both cold and hot water supply valves at the wall before you begin. Turn off water and disconnect power — do not work on the machine with power or water on. 2) Confirm the symptom and basic causes: Note whether the machine does not fill at all, fills slowly, fills continuously, or leaks from the valve connection at the rear. If only one side (hot or cold) is affected, problem is often one solenoid or a clogged screen on that port. 3) Check supply and hoses: Make sure home water is on and pressure is normal. Inspect the fill hoses for kinks, blockages, or collapsed hoses. Remove the hoses and run water into a bucket to verify supply. 4) Inspect inlet screens/filters: Unscrew the fill hoses from the washer. Inside the hose threads or valve ports you’ll usually find small mesh screens. Debris can clog these and mimic a bad valve. Clean screens with a toothbrush or replace them if damaged. 5) Look for external leaks and loose fittings: Check the rear valve threads and hose washers. Replace a worn rubber washer in the hose before assuming valve failure. 6) Access the inlet valve: Depending on your model, remove the rear access panel or top panel to reach the inlet valve mounted at the back of the washer where hoses attach. Take pictures of wire connections before removing. 7) Visual inspection: Check valve body for cracks, mineral buildup, or water tracks. Check wiring harness and connectors for burn marks or corrosion. 8) Test the solenoids electrically: With the washer unplugged and connectors removed, test each solenoid coil with a multimeter for continuity (ohms). Typical coil resistance is often in the hundreds to low thousands of ohms (common ranges ~300–1,500Ω) — consult your model spec if available. Open (infinite) or very low (short) readings indicate a bad coil. 9) Test valve operation under power (advanced): If comfortable and safe, you can restore power and activate a fill cycle while back-probing the valve harness to confirm the control is sending voltage to the solenoid. Do this only if you understand live-voltage work; otherwise skip and rely on continuity and symptoms. 10) Replace the valve: If solenoids fail, screens are clear, and hoses and supply are good, replace the inlet valve assembly. Steps: a) Shut water & power. b) Remove hoses and electrical connectors (label wires). c) Remove mounting screws and lift out the valve assembly. d) Transfer any small parts (brackets, gaskets) to the new valve and install new rubber washer(s) in hoses. e) Mount the new valve, reconnect wiring and hoses, turn on water slowly and check for leaks. 11) Test machine: Plug in the washer, run a short fill cycle and observe: correct fill speed, no continuous fill, no leaks. Re-check hose connections and tighten if necessary. 12) Final checks & cleanup: Ensure the washer completes a fill/drain cycle normally. If issues persist (control board not sending voltage), the problem may be the timer or control board rather than the valve. Safety note: Always disconnect power and water before working on the washer. If you are not comfortable working with live voltage or testing with power on, hire a qualified technician. Wear gloves and eye protection when handling old parts and debris.
Common Symptoms
Washer won’t fill, fills slowly, overfills/continues to fill, only hot or cold fills, water leaking from the rear hose connection or valve body.
Common Causes
- Failed solenoid coil(s) inside the inlet valve assembly (open or shorted)
- Clogged inlet screens/filters blocking water flow
- Cracked valve body, worn hose washer, or loose fittings causing leaks

Helpful Repair Tip
Listen for the inlet solenoids clicking when a fill is requested. Also measure each solenoid coil with a multimeter — one bad coil or an open circuit confirms the valve needs replacement.
Frequently Asked Questions
How long does replacing the water inlet valve take?
Most DIYers can replace the valve in 30–60 minutes once panels are removed. Diagnosis (checking hoses, screens, and testing solenoids) can add time. Allow extra time for ordering the correct part.
Can I replace just one solenoid instead of the whole valve?
Many inlet valves are sold and replaced as a complete assembly. Some models allow swapping individual solenoids, but that requires matching parts and careful transfer of seals. For reliability and to avoid future leaks, replacing the complete valve assembly is usually recommended.
