LG Washer IE Error Code: What It Means & How to Fix It

IE = Water supply inadequate. IE on an LG washer means not enough water is coming in. LG lists the usual causes as a valve that isn't fully open, a kinked hose, clogged inlet filters or low water pressure.

Can you fix it yourself? Yes

Check your model: Error codes can mean different things on different LG models. Find your model number (usually on a sticker inside the door or lid, or on the back) and confirm the code in your user manual.

Safety first: Unplug the appliance (or switch off its breaker) before you remove panels, filters or hoses. Turn off the water supply valves before you disconnect any hose, and keep a towel and shallow pan handy. Never work on wiring, gas lines or sealed refrigerator systems yourself.

How to fix LG Washer IE

Open both supply taps fully.
Straighten or reinstall any kinked inlet hose.
Turn off the water, disconnect the hose at the washer and check the small inlet filter screen. Clean it if it's clogged.
Reconnect, turn the water back on and restart. LG lists a working pressure of 14.5–116 psi.

Still showing IE?

If pressure is low throughout the house, LG suggests calling a plumber. If pressure is fine and the screens are clean, schedule service for the inlet valve.

Repair or replace?

If the appliance is under warranty, call LG first, since a repair may be free. Out of warranty, a common rule of thumb is to compare the repair quote with the cost of a new unit and the appliance's age before deciding.
