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

The LG washer IE error code means the washer is not filling with water fast enough. IE stands for Water Inlet Error. During the fill part of the cycle, the washer expects the tub to reach a certain water level within a set time. If it does not, it stops, drains if needed, and shows IE. In most cases the cause is simple: a tap that is not fully open, a kinked or frozen inlet hose, or a blocked inlet filter.

LG’s own troubleshooting page gives the same meaning: the IE error is displayed when water is not supplied to the tub and the water level does not rise to an adequate level within a specified period of time. This guide explains what IE means, the most likely causes in order, the safe checks you can do yourself, and when to call a professional.

What the LG IE error code means

Your LG washer fills through one or two inlet hoses connected to the hot and cold taps. An inlet valve inside the washer opens to let water in, and a water-level sensor watches the tub as it fills. If the level does not rise as expected, the washer assumes the water supply is the problem and shows IE (also written as 1E on some displays).

The washer may show IE at the very start of a cycle, when it first tries to fill, or later, when it needs more water for a rinse. If the machine has filled partly and then stops, do not assume the code is wrong: a slow fill, a hose that is partly blocked, or low water pressure can all cause the same code.

What IE does not mean

It is not a drain fault. A washer that will not drain shows a different code, OE, on LG machines.
It is not a door fault. A door that will not lock shows a different code, dE, on LG machines.
It is not a load or balance fault. An unbalanced load shows UE on LG machines.
It does not mean the washer is broken beyond repair. Most IE faults are caused by the water supply, the hoses or the inlet filter, and are fixed without opening the washer.

Most likely causes of IE, in order

The water tap is turned off, or not fully open. This is the most common cause, and the easiest to miss, especially after the washer has been moved, after plumbing work, or after a holiday. Both the hot and the cold tap need to be fully open.
A kinked, squashed or bent inlet hose. If the washer has been pushed back against the wall, an inlet hose can be pressed flat or bent sharply. Water can still trickle through, but not fast enough to fill the tub in time, so the washer shows IE.
A blocked inlet filter. Each inlet hose has a small mesh filter where it joins the washer. Limescale, sand and debris from the water supply collect in the filter over time and slow the fill. In hard-water areas this is a common cause.
A frozen inlet hose. In cold weather, a hose in an unheated room, garage or against an outside wall can freeze. LG’s advice is to thaw a frozen hose with warm water, never with boiling water, and never with a naked flame.
Low water pressure in the home. If the mains pressure is low, or another tap or appliance is using water at the same time, the washer may fill too slowly. Try a cycle when no other water is being used, and check whether other taps in the home are also slow.
A faulty inlet valve. The valve that lets water into the washer can fail, jam, or fail to open fully. If the taps are open, the hoses are clear and the filters are clean, and the washer still does not fill, the valve is the likely cause, and it needs to be tested and replaced by a professional.
A faulty water-level sensor or control board. This is the least common cause. If water is reaching the washer normally and the tub fills to the right level but IE still appears, the sensor that measures the level, or the board that reads it, may be at fault.

Safety STOP, read this before you start. Turn off the water supply taps and switch the washer off at the socket or breaker before you disconnect any hose. Water from a disconnected inlet hose can flood a room in seconds, so keep towels and a bucket nearby and work slowly. Do not open the washer, remove the top or back panel, or touch the inlet valve or the wiring inside. Those parts are not user-serviceable on this fault. If you see water leaking from inside the washer, or from a damaged hose, turn off the taps and the power and call a professional.

How to fix the LG IE error code safely

Tools you will need: towels and a bucket, a pair of pliers, and an old toothbrush. Time: about 30 minutes. Difficulty: easy for the checks in this section; testing or replacing the inlet valve is professional-only.

Check the taps. Find the hot and cold water taps behind the washer and turn both fully on. If either tap is stiff or will not turn, do not force it with a spanner; call a plumber or a professional.
Check the hoses. With the power off, pull the washer gently forward, if you can do so safely, and look at the inlet hoses. They should run in a smooth curve with no sharp bends, kinks or squashing. Straighten any bend and push the washer back carefully, without trapping a hose behind it.
Check for frozen hoses. If the room is cold and a hose feels stiff or icy, the water inside may be frozen. LG advises thawing the hose with warm water under 50 degrees Celsius (122 degrees Fahrenheit). Pour warm water around the outside of the hose, never boiling water, and wait for the ice to melt.
Clean the inlet filters. Turn off both water taps and unplug the washer. Place a towel and a bucket under the hose connections, unscrew the inlet hoses from the back of the washer, and look for the small mesh filters inside the inlet valve openings. Lift each filter out with pliers, rinse it under the tap, and brush away debris with an old toothbrush. Refit the filters, reconnect the hoses firmly by hand, and turn the taps back on. Check for drips before you start a cycle.
Check the water flow. With the hoses disconnected and a bucket ready, turn each tap on briefly and check that water flows strongly from the hose into the bucket. If the flow is weak from one tap, the problem may be in the household plumbing, not the washer.
Reset the washer and run a test cycle. Plug the washer back in, close the door, and press the Power button, then Start. If IE returns at once, or the tub still does not fill, stop the cycle, turn off the water and the power, and call a professional. Do not keep running cycles that cannot fill.

When to call a professional

Call an LG-approved appliance engineer, or LG Support, if any of the following apply:

IE returns after the taps, hoses and filters have been checked and cleaned.
The washer does not fill at all, or fills very slowly, even though water flows strongly from the hoses.
A hose, tap or connection is damaged or leaking.
The inlet valve, the water-level sensor or the control board needs to be tested or replaced.
The washer is still under warranty. Do not open it yourself while it is under warranty.
There is any sign of water leaking from inside the washer.

How much does it cost to fix an LG IE error in the United States?

We could not verify a reliable, current price range for an IE repair from LG or from a published United States repair source, so we are not publishing a figure here. The cost depends on the cause: a tap, a hose or a filter costs nothing to fix, while a replacement inlet valve is a part plus labour. Ask the engineer for a written quote before the work starts, and ask whether the call-out fee is included in the repair price.

Parts you may need

Parts are named here only, with no prices or links to sellers, because the right part depends on your exact model number:

Water inlet hose, hot and cold
Inlet valve filter, mesh screen
Water inlet valve
Water-level sensor, pressure sensor
Control board

Always check the part against your model number on the rating plate, which is usually on the back of the washer or inside the door. Do not order a part on the strength of the IE code alone, because the code does not identify a single faulty part.

Frequently asked questions

Can I still use my LG washer with the IE error code?

No, not normally. The washer cannot fill with enough water to wash or rinse properly, so it stops the cycle. Running it again without fixing the water supply will show the same code, and may leave detergent in the laundry.

Will resetting my LG washer clear the IE error code?

Sometimes, if the cause was a tap left off or a one-off slow fill. Switch the washer off, check the taps and hoses, then switch it back on and start a cycle. If IE returns, the water supply problem is still there, and a reset will not fix it.

Is IE the same as 1E?

Yes. On some LG displays the letter I looks like the number 1, so IE may appear as 1E. It is the same Water Inlet Error, and the checks are the same.

Can low water pressure cause the IE error code?

Yes. If the mains pressure is low, or another tap, shower or appliance is using water at the same time, the washer may fill too slowly and show IE. Try a cycle when no other water is being used, and check whether other taps in the home are slow too.

How do I clean the inlet filters on an LG washer?

Turn off the water taps and unplug the washer, unscrew the inlet hoses from the back of the washer, lift the small mesh filters out of the inlet valve openings, rinse them under the tap and brush away any debris, then refit them and reconnect the hoses. Check for drips before you start a cycle.

Should I replace the inlet valve myself?

No. The inlet valve is inside the washer, connected to the water supply and the wiring. Testing it and replacing it means opening the machine, so leave it to a professional, and do not open the washer while it is under warranty.
