LG Washer Not Filling with Water? Inlet Valve 5221ER1003A – Fix No-Fill Fast

If your LG washer won’t fill with water, fills too slowly, or stops mid-cycle, the water inlet valve is the most common cause. In most LG front-load washers, the dual-solenoid inlet valve controls both hot and cold water entry — when it fails, the washer may fill on only one temperature, not fill at all, or trigger an IE (inlet error) fault code and stop the cycle. ⚡ Common failure point in LG-built front-load washers. Part 5221ER1003A is the genuine OEM replacement that restores full hot and cold water fill function immediately with no modification required.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Your washer powers on and the control panel functions normally
• ✔ Water supply hoses are connected, valves are open, and water pressure is confirmed adequate
• ✔ The drain pump and drum spin function correctly
• ✔ The door latch and door lock are functioning and the door seals properly
• ✔ ONLY problem is no water fill, slow fill, or fill on one temperature only

🔧 Common Symptoms

• Washer won’t fill with water — drum stays dry after starting a cycle
• Washer fills with cold water only, or hot water only
• Washer fills very slowly and takes much longer than normal
• IE error code displayed on the control panel
• Washer starts, pauses, then displays an error and drains without washing
• Humming sound from the valve area but no water enters the drum

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this water inlet valve restores normal fill function immediately.

⚙️ Installation

Skill Level: Moderate — 20–35 minutes. Disconnect power and turn off water supply before beginning. Access the valve by removing the rear panel — disconnect the two water supply hoses, unplug the solenoid wire harness connectors, remove the mounting screws, and swap the valve. Reconnect hoses hand-tight plus a quarter turn and restore power. Run a short fill cycle and check for leaks at both hose connections before closing the panel.
