LG Washer IE Error
What it means
The IE error on an LG washer is a water-inlet error (Inlet Error) — the machine isn't filling with enough water in time. It usually points to the water supply, the inlet hoses, or the small inlet filter screens.
The bottom line on the IE error
The IE error means the washer could not fill fast enough, and nine times out of ten the real culprit is a supply valve that is not fully open or a clogged inlet screen, not a failed part. It is a safe DIY check, but restarting only clears IE for one cycle until the real water restriction is gone.
Start cheap: open both valves fully, straighten the hoses, and rinse the inlet screens. That fixes most cases for $0; only if it still will not fill is the inlet valve worth replacing at $25-$70 — cheaper than a new $700-$1,200 washer.

Common causes of the IE error
- Water supply valves not fully open
- Kinked or crushed water inlet hoses
- Clogged inlet filter screens where the hoses connect
- Low household water pressure
- Faulty water inlet valve (less common)
Which LG washers get the IE error
The IE inlet error appears on both LG front-load washers (WM-series) and top-load washers (WT-series) that use a water-level pressure sensor and electronic inlet valves, spanning most models from roughly 2010 onward. Because it is triggered by the water supply or inlet screens rather than a model defect, it can show on any of these units — most often after the fill hoses are shut off, kinked, or the inlet screens have collected sediment.
How to fix the LG Washer IE error
- 1Check the supply valvesMake sure both hot and cold water valves behind the washer are fully open.
- 2Inspect the inlet hosesStraighten any kinks and ensure the hoses aren't crushed behind the machine.
- 3Clean the inlet filter screensTurn off the water, unscrew the fill hoses from the back of the washer, and rinse the small mesh screens that catch sediment.
- 4Reconnect and testReattach the hoses, turn the water on, and start a cycle to see if IE clears.
🧰 When to call a professional
If the supply, hoses, and screens are fine but IE persists, the water inlet valve or control board may need replacement — call a technician.

How this code stacks up against related error codes for difficulty, urgency, and cost.
| LG IE | LG OE | Samsung 4C | |
|---|---|---|---|
| DIY difficulty (1–5) | 2 | 2 | 2 |
| Urgency (1–5) | 2 | 2 | 1 |
| Typical cost | $ | $ | $ |
How much does it cost to fix the IE error?
| DIY fix (open valves / clean screens) | $0 |
| Inlet filter screens / new fill hoses (part) | $10–$30 |
| Water inlet valve (part) | $25–$70 |
| Professional repair (parts + labor) | $120–$250 |
Repair or replace?
IE is usually free to fix — opening the supply valves fully, straightening the hoses, and rinsing the inlet screens clears most cases. If the water inlet valve itself has failed, the part is inexpensive ($25–$70) and is a common, straightforward replacement, so repair makes sense rather than replacing a washer that typically costs $700–$1,200+. Replacement is only worth considering on an older machine with several other failing parts. Prices vary by model and region.
Common replacement parts for the IE error
| Water inlet valve | $25–$70 | If the supply, hoses, and screens are all clear but the valve will not open enough to fill. | |
| Inlet filter screens | $5–$15 | The small mesh screens in the inlet ports; often just need cleaning rather than replacing. | |
| Fill hoses | $10–$25 | If a hose is kinked, crushed, or its washer/screen is damaged. |
Prices are typical retail ranges and vary by model and supplier — always confirm the exact part number for your appliance before buying.
LG IE error — FAQ
＋ − What does IE mean on an LG washer?
IE is a water-inlet error — the washer didn't fill with enough water in the expected time.
＋ − How do I fix the IE error?
Confirm the supply valves are open, straighten the inlet hoses, and clean the small filter screens where the hoses connect to the washer.
＋ − Can low water pressure cause an IE error?
Yes. If household water pressure is low, the washer may fill too slowly and trigger IE.
＋ − Can frozen hoses cause an IE error in winter?
Yes. LG notes that in cold weather the faucet or supply hose can freeze and cut off flow. Thaw a frozen faucet with a hot-water-soaked towel and warm the hose with water no hotter than about 50°C (122°F) before retrying.
