LG Washer Not Filling With Water? Here's the Fix
LG Washer Not Filling With Water?
Diagnose the cause and find the right replacement part — fast shipping across Canada and the USA
An LG front-load washer that won't fill with water — or fills too slowly — will stop mid-cycle, display an IE error code, or simply sit with the door locked and no water entering the drum. The water inlet valve is the most common cause on LG front-load washers. This guide walks you through every likely cause, how to confirm it, and the exact part you need.
How the Water Fill System Works on LG Front-Load Washers
LG front-load washers use a dual-solenoid water inlet valve — one solenoid controls cold water, the other controls hot water. The control board opens the appropriate solenoid(s) at the start of each fill cycle. A pressure sensor (not a float switch like top-loaders) monitors water level and signals the board when the correct amount of water has entered. If either solenoid fails, the corresponding water temperature won't enter the drum.
Most Common Causes
1. Failed Water Inlet Valve — Most Common Cause
The solenoid coil inside the valve burns out, the valve screen becomes clogged with mineral deposits, or the valve body cracks. A failed cold water solenoid means no cold water enters; a failed hot water solenoid means no hot water. The washer may still partially fill on one temperature but display an IE error or fail to reach the correct water level.
How to confirm: Disconnect power. Remove the valve and test each solenoid coil with a multimeter — a working solenoid reads 200–1000 ohms. No continuity or open circuit = failed solenoid. Also inspect the inlet screens for mineral buildup.

The IE error code on LG washers means the machine failed to fill to the required water level within the allotted time. This is almost always caused by a failed or partially clogged inlet valve, low water pressure, or a kinked supply hose.
How to confirm: Check that both hot and cold supply valves are fully open and supply hoses aren't kinked. If supply is confirmed good, test the inlet valve solenoids.

LG washers require a minimum of 14.5 PSI (1 bar) to open the inlet valve fully. If home water pressure is low or the supply valves are partially closed, the washer may fill slowly or trigger an IE error.
How to confirm: Ensure both supply valves are fully open. Test home water pressure at a nearby tap with a gauge.

The inlet valve has mesh screens at each water connection point. In hard water areas, mineral deposits can clog these screens and restrict flow without the valve itself failing. Cleaning the screens may restore flow temporarily, but replacement is the more reliable long-term fix.
How to confirm: Disconnect the supply hoses and inspect the screens at the valve inlets. Visible white or brown mineral buildup indicates clogging.

1. Unplug the washer and turn off both water supply valves. 2. Pull the washer away from the wall. 3. Remove the rear access panel (usually 4–6 screws). 4. Locate the inlet valve at the top rear of the machine where the supply hoses connect. 5. Disconnect the supply hoses (have a towel ready for residual water). 6. Disconnect the wiring harness from the solenoids. 7. Remove the mounting screws and swap the valve. 8. Reconnect hoses and wiring. 9. Restore power and water, and run a test cycle.

Frequently Asked Questions
What does the IE error code mean on an LG washer? IE stands for Inlet Error — the washer failed to fill to the required water level within the allotted time. The inlet valve is the most common cause. Check supply hoses first, then test the valve solenoids.
Can I replace just one solenoid? The solenoids are not sold separately — the entire valve assembly is replaced as a unit. This is the standard repair approach and ensures both solenoids are fresh.
Is this a DIY repair? Yes — moderate difficulty. The valve is accessible through the rear panel without major disassembly. Total time: 30–45 minutes. Contact us if you need model-specific guidance.
What if I replace the valve and the washer still won't fill? Check the pressure sensor and its hose next — a clogged or disconnected pressure sensor hose can also cause fill errors. Contact us and we'll help diagnose further.
