LG IE fault codewhat it means and how to fix it
The drum did not fill to the level it wanted in the time allowed. LG treat IE and 1E as the same code, so you do not need to tell them apart.

What IE means
LG describe this as a water inlet error, occurring when the tub does not fill to an adequate level within a specified period. Their UK wording is simply that the machine is not getting enough water. The first thing to settle is one that worries a lot of people unnecessarily. On a seven-segment display a capital I and the digit 1 are drawn identically, and readers spend time trying to work out which they are looking at. They do not need to: LG title their own help article "1E(IE) error code appears on display" and list the code as IE, E02 and E10 in the same entry. It is one fault with several renderings, and the remedy is the same whichever you read. Everything on the cause list sits outside the machine, which is why this is worth ten minutes before booking anybody. A tap left shut after plumbing work, a hose crushed behind the machine, or the small mesh filter in the inlet connector silted up with grit from the mains will each produce it.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Tap closed or only part open | Free to check and more common than anyone admits. Taps behind machines get knocked by whatever is stored under the counter. | Common |
| Inlet mesh filter blocked | A gauze screen where the hose meets the machine, catching grit from the mains. In hard water areas it silts up over a few years. | Common |
| Fill hose kinked | Created by pushing the machine back too far, so the hose is crushed against the wall or the waste pipe. | Common |
| Low mains pressure | Sometimes genuinely the house rather than the machine, particularly on a shared supply at peak times or after mains work in the street. | Occasional |
| Inlet valve failed | The solenoid that admits water has stopped opening. The real repair on this list, and diagnosed only after the supply is proven. | Occasional |
What to try yourself
Check the tap behind the machine is fully open — turn it right off and right on again rather than judging by how it looks.
Turn the tap off, unscrew the fill hose at the machine end into a bucket, and look into the connector for the small gauze filter. Rinse it until you can see light through it.
Turn the tap off before unscrewing anything, and keep a towel to hand for what is still sitting in the hose.With the hose off, run the tap into a bucket for thirty seconds. A strong flow means the supply is fine and the fault is in the machine; a trickle means you have found it.
Pull the machine out and follow the fill hose end to end, straightening any kink and freeing it from behind a foot or the waste pipe.
Reconnect finger tight plus a quarter turn — these seal on a rubber washer — then run a short cycle and check both ends for weeping.

What it costs to fix
Typical repair cost
£0–£150
Time on site
25 minutes
Free if it is the tap, the hose or the filter. A replacement inlet valve is around £90 to £150 fitted. A new fill hose costs a few pounds and is worth changing while you are there if it looks tired.

Common questions about LG IE
Is my code IE or 1E?
It does not matter. LG treat them as the same code and title their own article "1E(IE)". Whichever you are reading, the fault and the fix are identical.
Everything is open and flowing well. What now?
Then the supply is eliminated and it points at the inlet valve or the level sensor. That is an engineer visit, but you have removed the free causes and can say so, which should keep the visit short.
Could low pressure in the house be the cause?
It can be, especially on a shared supply at busy times or after work on the street main. The bucket test tells you: if the tap alone struggles to fill a bucket briskly, the machine is not being given what it needs.
