Understanding the Problem
If water is dripping from the back or front of your LG washing machine near the inlet hoses, or the washer continues to fill when it should be off, the water inlet valve (also called the fill valve) is a common culprit. The inlet valve controls water entry into the washer. Over time seals and diaphragms inside the valve wear, solenoids can fail, or the valve body can crack — all of which can allow water to leak or fail to shut off completely. Leaks can be external (visible at hose connections or the valve body) or internal (water entering the washer tub or leaking into the cabinet). Small leaks can cause puddles under the machine or activate floor safety devices; internal leaks can lead to overflowing, water in the detergent drawer, or error codes. Because multiple parts and connections are near the inlet (hoses, clamps, screens and the valve), a methodical inspection is the fastest way to identify the true source.
Common Symptoms
Visible dripping from rear hose connections or valve, washer overfills or won't stop filling, water inside cabinet, puddles on the floor, error codes related to filling or drainage, or weak/slow fill due to clogged inlet screens.
Common Causes
- Worn or degraded valve seals/diaphragms inside the inlet valve allowing constant flow
- Cracked valve body or failed solenoid causing external or internal leaks
- Loose or damaged inlet hoses, clamps, or clogged inlet screens causing improper sealing

Helpful Repair Tip
Shut off water supply, disconnect inlet hoses and place a towel under the valve. Turn water on briefly to see if the valve body itself leaks (not the hose). Also run a short cycle with the hoses removed and catch any drips — if water continues after the valve should be closed, the inlet valve assembly or its solenoids are likely bad.
Frequently Asked Questions
Can I keep using the washer if the inlet valve is leaking?
No — continue use risks water damage and mold. If you see a leak, shut off the water supply to the washer and either disconnect the inlet hoses or replace the faulty part before using the machine again.
How do I replace the inlet valve on an LG washer?
Turn off power and water. Pull the washer away from the wall, disconnect the inlet hoses and electrical connector, then remove the top or rear panel to access the valve. Unbolt the valve from the mounting bracket, swap in the new valve (or solenoids/seals), reconnect wiring and hoses, restore water and power, and test for leaks. Because details vary by model, consult your model-specific service guide or get the exact replacement part number before ordering.
