LG Washer Error Code IE: Restore Water Fill

The Logic Verdict

LG’s factory trainer keeps the IE workflow tight: open the faucets, confirm incoming pressure sits between 20–80 PSI, straighten the hoses, and clean the inlet filters with pliers and a soft brush. If sediment or low pressure chokes the flow, the tub never reaches level and the board times out at the eight-minute mark. Once the lines run at full volume the code clears itself—otherwise you move to replacing the triple water valve.

What It Means

IE (sometimes shown as 1E) = the washer couldn’t reach its programmed fill level in time. The control energizes the hot and cold solenoids and expects the pressure sensor to rise quickly. Closed taps, kinked hoses, clogged inlet screens, or a weak 5220FR2075L valve keep the tub shallow, so the unit drains and flashes IE until the restriction is gone.

Common Causes

• Low supply pressure. Wells, RO systems, or partially closed house shutoffs drop the flow below LG’s 20 PSI minimum.
• Closed or partially opened faucets. Either valve left half shut will slow the fill and trigger IE.
• Kinked or elevated hoses. Pushing the cabinet against the wall or routing hoses uphill starves the tub of water.
• Clogged inlet screens or failed solenoids. Mineral flakes plug the filters, and tired valve coils can’t open fully.

Step-by-Step Fix

1. Shut the cycle down. Press Power to stop the beeper, then unplug the washer or flip the breaker.
2. Open the taps all the way. Turn both the hot and cold valves counter-clockwise until they bottom out, and verify the main laundry shutoff or well pressure switch is on.
3. Check supply pressure. Thread a hose-pressure gauge onto the cold faucet and open it. LG requires 20–80 PSI; anything below that must be corrected before you chase the washer.
4. Straighten the hoses. Slide the cabinet forward a few inches, remove any kinks or tight bends, and reroute the hoses so they’re lower than the top of the tub.
5. Clean the inlet screens. With the taps off, remove each supply hose, use needle-nose pliers to pull the plastic filter and seal, and scrub the screen under running water with a soft brush as shown in the video. Reinstall the gasket and screen so they sit flush, hand-tighten the hoses (no pliers), and reopen the valves while watching for leaks.
6. Test fill volume. Restore power, start a quick cycle, and listen for a strong rush of water. If the tub still dribbles, replace the inlet valve assembly, reconnect the harness, and rerun the test—IE will clear once the board sees a normal pressure rise.

Parts & Tools

• LG 5220FR2075L water inlet valve (fixes slow fills caused by weak solenoids)
• Watts 0950200 hose pressure gauge (verifies you’re within LG’s 20–80 PSI requirement)
