Understanding the Problem
If your LG washer is leaking water from the valve area (usually at the back near the water inlet hoses or under the top panel), the most common culprit is the water inlet valve assembly or its seals. The inlet valve controls incoming water and can develop internal leaks from worn valve seats, cracked housing, or failed solenoids. Leaks can occur while the machine is filling, after it's off, or continuously if the valve fails to close completely. A leaking inlet valve can cause puddles under the washer, soggy floors, or even error codes on some LG models. Before attempting a repair, cut power and shut off the water supply. Inspect hoses and clamps first (simple fixes), then the inlet valve itself. Replacing the inlet valve or its seals resolves most valve-related leaks, but also check the inlet hoses, hose connections, and the washer chassis for secondary damage caused by the leak.
Common Symptoms
Puddles under the washer; water dripping from the back or base during or after filling; washer overfilling or running continuously; visible corrosion or mineral buildup on valve or hose fittings.
Common Causes
- Worn or damaged inlet valve seats and seals allowing internal leakage
- Cracked or degraded valve housing or solenoid assembly
- Loose or damaged inlet hoses/clamps or debris caught in the valve causing poor sealing

Helpful Repair Tip
To confirm the inlet valve: shut off water and power, place towels under the valve area, run a short fill cycle with the rear panel accessible, and watch the inlet valve body and hose connections—if water appears at the valve body or from between the valve and hose, the valve or its seals are the likely cause.
Frequently Asked Questions
How can I tell if the inlet valve is the part leaking?
Start by shutting off water and power. Inspect the rear hose connections—tighten clamps if loose. Remove the top or back panel and run a short fill cycle while watching the valve area. If water is coming from the valve body (not the hose connection) or dripping between the valve and the water inlet hoses, the inlet valve or its internal seals are likely failing. Visible cracks, mineral buildup, or water pooling on the valve are also indicators.
Can I replace the inlet valve myself, and how much will it cost?
Yes — most homeowners with basic tools (screwdriver, pliers) can replace the inlet valve. Typical steps: unplug washer, shut off water, disconnect inlet hoses, remove access panel, unplug valve wiring, unbolt valve, swap in new unit, reconnect hoses and power, then test. Replacement parts cost depends on model and supplier but expect roughly $30–$120 for a valve assembly; labor varies if you hire a technician. If your washer is under warranty or you’re uncomfortable working with water/electrical connections, call a qualified appliance technician.
