Understanding the Problem
What the water inlet valve does: The water inlet (fill) valve controls cold and hot water entry into the washer. The washer control energizes the appropriate solenoid(s) on the valve to open and let water in for fill cycles. Over time the valve can fail electrically (solenoids), mechanically (stuck/plastic debris), or leak. Common repairs are cleaning the inlet screens or replacing the valve assembly. Step-by-step diagnostic and repair steps: 1) Safety first: unplug the washer and turn both hot and cold water supply valves off. If you can't reach the plug, switch the breaker off. Always relieve pressure in the hoses by opening one of the supply valves slightly before disconnecting. 2) Confirm symptom and isolate: Run a fill cycle and observe. Does no water come in at all, one side only (hot or cold), very slow fill, or constant dripping? This helps narrow the cause. 3) Check supply: Ensure household shutoff valves are fully open and water is present at those valves. Remove the hose from the house plumbing briefly (catch water) to confirm supply flow. 4) Inspect fill hoses and screen: Disconnect inlet hoses at the washer. Inspect the small mesh screens inside the inlet valve ports and the hose end washers for debris or mineral buildup. Clean screens with a small brush or replace if damaged. 5) Electrical check: Reconnect hose(s), restore power with the back panel removed so you can access the valve. Put the washer into a fill cycle. Using a multimeter, check whether the control is sending voltage to the valve solenoids during the fill command (typically 120 VAC on US models). If you do not see voltage to the valve but the control is commanding fill, the control/timer is suspect. If voltage is present and valve does not open, the valve is bad. 6) Coil continuity test (with power off/unplugged): Disconnect the electrical connectors from the valve. Use a multimeter to measure resistance across each solenoid coil. Typical solenoid resistance for top-load valves is a few hundred ohms; an open circuit (infinite) indicates a burned coil. If you get a very low shorted reading or infinite, replace the valve. 7) Observe for leaks: If valve body or seals are cracked or the valve leaks when the washer is off, replacement is required. 8) Replacement steps (summary): a. Unplug washer and shut off water supply. b. Pull washer away from wall and remove the back panel or top access (model dependent) to reach the inlet valve at the top-rear. c. Place a towel to catch water, disconnect water hoses from the valve and remove the wire harness connectors (note or photograph connector locations). d. Remove mounting screws securing the valve assembly and lift out the valve. e. Install the new valve in the same orientation. Replace hose washers and tighten supply hoses hand-tight + 1/4 turn; do not overtighten. f. Reconnect electrical connectors to correct solenoids, reattach panels, turn water on slowly while checking for leaks, plug in, and run a test fill cycle. 9) Final check: Verify correct hot/cold operation (hot on hot side, cold on cold). Confirm no leaks and that fill levels/times are correct. Safety note: Always unplug or kill power before disconnecting wires. Water and electricity together are dangerous—if you are not comfortable testing live voltage, hire a service tech.
Common Symptoms
Washer won't fill, fills very slowly, only fills with cold or hot, continuous small leak from inlet area, or valve buzzes but no water flows.
Common Causes
- Clogged inlet screens or mineral buildup in valve ports
- Failed solenoid coil (open or shorted) on the valve assembly
- Control board/timer not sending voltage to the valve
- Damaged valve body or internal seals causing leaks
- Restricted household water supply, kinked hoses, or closed shutoff valves

Helpful Repair Tip
If one side (hot or cold) doesn't fill but the other does, test the solenoid coil for that side with a multimeter; an open coil almost always means the valve must be replaced rather than repaired.
Frequently Asked Questions
Can I clean the inlet valve instead of replacing it?
Yes—if the problem is mineral or debris buildup in the screens, cleaning both the inlet screens and the hose-end filters can restore normal flow. However, if a solenoid coil is open, if the valve leaks, or if the valve fails to open when energized, cleaning won't fix it and you'll need to replace the entire valve assembly.
How long does it take to replace the water inlet valve?
For a competent DIYer with basic tools it typically takes 30–60 minutes: shut off water and power, remove access panel, disconnect hoses and electrical connectors, swap the valve, and reassemble. Allow extra time to diagnose and to test for leaks.
