LG Washer IE Error Code — Water Inlet Fix
The LG IE error code (Inlet Error) triggers when the washer doesn't detect water entering the drum within the expected time. Like Samsung's 4E error, this is usually caused by something upstream of the inlet valve — the water supply valves being closed or the small mesh screens inside the inlet connections being clogged with sediment. Check these first before testing or replacing the inlet valve.

Common Symptoms
- IE error code on the display
- Washer starts but drum doesn't fill
- No sound of water entering the machine
- Cycle stops within the first 2–3 minutes
- Partial fill then IE error
Most Likely Causes
- 1
Supply Valves Closed or Partially Open
The hot and cold water valves behind the washer must be fully open. A valve that's partially turned off reduces flow below the required threshold and triggers IE. This is the simplest possible cause — check it first.
- 2
Clogged Inlet Screen Filters
Small mesh screens inside the hose connection ports on the back of the washer filter sediment from the water supply. They can clog gradually over years. Removing and cleaning these screens takes 5 minutes and clears many IE errors.
- 3
Kinked Inlet Hose
If the washer is pushed too close to the wall, the inlet hoses can kink where they bend at the back of the machine. Pull the machine forward and check both hoses.
- 4
Faulty Water Inlet Valve
The inlet valve contains solenoids that open when energized by the control board. A failed solenoid keeps the valve closed. Test each solenoid with a multimeter — they should read 100–400 ohms. A solenoid reading open (infinite) has failed.
- 5
Control Board Not Energizing the Valve
Rarely, the control board fails to send the correct voltage to the inlet valve solenoids. Verify the valve solenoids test good before suspecting the board.

Quick DIY Checks
Always turn off the water supply valves before disconnecting any hoses. Unplug the washer before testing solenoids or accessing internal components.
- 1Turn both supply valves (hot and cold, behind the washer) fully counterclockwise to open completely. Even a quarter-turn restriction can cause IE. Restart the washer and try a normal cycle.
- 2Turn off the supply valves. Disconnect both inlet hoses from the back of the washer. Inspect the small mesh screens inside each hose port on the machine. Use needle-nose pliers to pull them out, rinse them under running water, and scrub with a toothbrush. Reinstall the clean screens and reconnect the hoses.
- 3Check both hoses for kinks along their full length. If a hose has been permanently kinked (the inner wall is creased), water won't flow adequately even after straightening — replace the hose.

- 5Test the inlet valve solenoids: unplug the washer and remove the rear access panel. Disconnect the wiring connectors from the inlet valve and test each solenoid with a multimeter set to ohms. Each solenoid should read 100–400 ohms. An infinite reading means that solenoid has failed and the valve needs replacement.

Repair vs Replace
IE errors are almost always caused by supply issues or a clogged screen — both free fixes. Even a failed inlet valve costs only $30–$70 in parts. This is never a reason to replace the washer.
Est. Repair Cost
$0 (supply valve / screen cleaning); $30–$70 (inlet valve replacement DIY)
Est. Replacement Cost
$700–$1,500 for a new LG washer

Frequently Asked Questions
- How do I clean LG washer inlet screens?
- Turn off both water supply valves. Disconnect the hoses from the back of the washer. Inside each hose port on the washer, you'll see a small circular mesh screen. Use needle-nose pliers to gently grip the screen and pull it straight out — don't tear it. Rinse under running water and scrub with a toothbrush. Reinstall the screen by pressing it firmly back into the port until it seats flush. Reconnect the hoses and turn the supply valves back on.
- LG washer IE error on cold wash only — what does that mean?
- An IE error only on cold cycles (but not warm or hot) points specifically to the cold water supply: the cold water valve is partially closed, the cold inlet screen is clogged, or the cold solenoid in the inlet valve has failed. Inspect the cold-side screen and fully open the cold water supply valve first. If those are clear, test the cold solenoid on the inlet valve with a multimeter.
- Can low water pressure cause an LG IE error?
- Yes. LG washers require a minimum water pressure of approximately 14.5 PSI (1 bar) to fill correctly. If your home has very low water pressure — particularly if you're in a high-rise building, have an older home with corroded pipes, or share water supply with many fixtures — the washer may trigger IE even with the valves fully open. Test by running water in a nearby sink while the washer fills and see if the IE error improves or worsens.
