LG Washer IE Code: Not Enough Water Coming In

What does the IE code mean on an LG washer?

IE stands for a water inlet error. LG's front-load code list says it appears "if the tub does not fill to an adequate level within a specified period," and newer displays may show it as E02 or E10 with the words "No Water Supply" ^[1]. LG's top-load list describes the same thing in plainer words: IE "may be displayed if the drum is not filled to a certain level" ^[2].

The washer does not measure the tap or the hose directly. It opens its inlet valve, waits, and checks the water level in the tub. Anything that slows or stops that water, or lets it escape, can run out the clock and trigger IE. That is why the causes range from a closed tap to a drain hose on the other side of the machine.

	Front-load LG washer	Top-load LG washer
What the display may show	IE, E02 or E10 (No Water Supply)	IE
LG's listed causes	Tap off or water cut off, hose bent or not connected, hose frozen	Water outage, closed tap, hose kinked or disconnected, frozen pipes or hose
Extra checks LG gives	Hot hose on the hot inlet; drain hose holder in place	Taps fully open; drain hose no deeper than 4 in (10 cm)
If it persists	Possible water supply valve fault	Inlet valve may be faulty; contact LG service

The table draws on LG's front-load and top-load code lists and LG's two IE help pages, cited in the sections below. LG dishwashers also use an IE code for a water supply problem, so make sure the code came from the washer. If you are not sure what a code means, look it up in our error code lookup.

What causes an LG washer IE error?

Every cause sits somewhere on the path the water takes: from the household supply, through the tap and inlet hose, past a small filter screen where the hose meets the washer, through the inlet valve, and into the tub. The drain hose matters too, because water that leaves while the tub fills never counts toward the level.

Cause	Clue you may notice	First fix
Tap closed or only partly open	Washer was just moved, installed or the plumbing was worked on	Open both taps fully, counterclockwise
Inlet hose kinked, pinched or loose	Washer pushed tight against the wall	Pull it out, straighten the hose, reconnect
Hot and cold hoses swapped	Recent install or hose change	Hot hose to the hot inlet, cold to cold
Clogged inlet filter screens	Fill has slowed over months	Unplug, shut taps, clean the screens
Low household water pressure	Weak flow at other taps too	Check another tap; call a plumber
Frozen hose or tap	Error starts on a freezing day	Thaw the hose and tap, or wait for a thaw
Drain hose siphoning	Water runs out of the drain while it fills	Reset the hose depth or drain hose holder
Inlet valve fault	All checks above pass	Book LG service

Taps and connections. LG's front-load IE page says to check whether the faucet is turned off or the water is shut off, and notes this often happens after the washer is moved or a boiler is repaired ^[4]. A tap that is open but not all the way is also a cause: LG's top-load IE guide says the fill time "can take longer than expected" when the taps are not fully open ^[3].

Bent hoses. A bent supply hose blocks the flow and can cause poor water supply or leaks. LG adds that the washer can move slightly from vibration during washing and spinning, which can pinch a hose that was fine at install ^[4].

Clogged inlet filters. LG says that over time the inlet filters can become clogged, slowing water flow. ^[3] Rust, sand and grit from the pipes collect on these small screens, so a fill that has slowly grown weaker points here.

How do you fix an LG washer IE code?

Work from the outside in. The first two checks take a minute and need no tools; only the filter cleaning needs the hoses off.

Step 1: Open the taps all the way

Check that both inlet hoses are attached to the taps and that each tap is fully open. LG says to turn a closed tap counterclockwise to open it ^[2]. LG also lists a water outage as a cause, so if the house water is off for a repair or an outage, wait for the supply to return and restart the cycle.

Step 2: Straighten the hoses and check hot and cold

Pull the washer away from the wall and look along both hoses. LG says to unbend and straighten the inlet hose; if a kink is severe, close the taps, disconnect the hose and reconnect it straight ^[2]. Replace a hose that is cracked, bulging or flattened rather than bending it back. On front-load models, LG also says the hot water hose must go to the hot water valve and the cold hose to the cold valve ^[4].

Step 3: Clean the inlet filter screens

Unplug the washer and shut both taps before you take a hose off; the hoses stay full of water, so keep a towel and a shallow pan ready. LG's top-load IE guide gives the order: turn off the water faucet, disconnect the power cord, unscrew the supply hose from the washer counterclockwise, pull the filter out with pliers, and clean it with a toothbrush under running water before you put it back ^[3]. LG's front-load list says the same filter can be removed with fingers or pliers to clear rust, sand and stones, and must be refitted before the hose goes back on ^[1].

Pull gently and straight out so the screen does not tear. Reattach each hose to the same inlet it came from, tighten it by hand, open the taps slowly and look for drips at both ends before you plug the washer back in.

Step 4: Thaw a frozen hose or tap

If IE shows up on a freezing day, the hose or the pipes feeding it may be frozen. LG's front-load list says to disconnect the supply hose and open the tap; if nothing comes out, wrap a towel soaked in hot water around the tap for 5 minutes. Thaw the hose in water of 50ºC or lower and reconnect it only when it is completely free of ice ^[1]. LG's top-load list gives that limit as below 50ºC (122°F) ^[2]. Never use an open flame on pipes. If the pipes in the wall are frozen, LG's top-load guide notes that the supply resumes once the temperature rises above freezing ^[3].

Can low water pressure cause an LG IE code?

Yes. LG's washer code guide says an IE on a top-load model means water is not being supplied "or that the water pressure is too low," and gives the required range: LG says the water pressure must be between 14.5 and 116 psi. ^[5]

For front-load models, the same guide asks you to make sure the water pressure is adequate; if it seems too low, check another tap in your home and consult a certified plumber ^[5]. A quick home test is to run the nearest sink or laundry tub: if that flow is weak too, the problem is the house supply, not the washer. Low pressure across the house is a job for a plumber or your water utility, and no amount of filter cleaning will fix it.

Why can a low drain hose cause an IE code?

This is the cause most owners miss, because the drain hose seems to have nothing to do with filling. LG says otherwise. If the drain hose sits too low, water flows out through it while the inlet valve is still filling the tub, so the level never builds.

LG's top-load IE guide says that if the drain hose is installed deeper than 4 inches (10 cm) into the drainpipe, it will cause siphoning as the washer fills ^[3]. On front-load models, LG warns that removing the drain hose holder drops the hose below the water level in the drum, and that if the end of the hose sits in water, it keeps draining by siphon action ^[4].

The fixes:

1. Pull the drain hose up so no more than 4 inches (10 cm) of it sits inside the standpipe, and secure it so it cannot slip out.
2. Keep the end of the hose out of standing water in a laundry tub or floor drain.
3. Leave the drain hose holder on the back of the washer in place. LG says that if the hose is too short, buy an extension drain hose instead of taking the holder off ^[4].
4. Do not fix it by going too far the other way. LG's top-load guide also warns against installing the drain hose too high, bent or blocked ^[3], which can lead to drain errors such as the LG OE code.

In our reading, two clues point to siphoning: you can hear water running into the standpipe during the fill, or the IE started right after the washer was moved or its drain hose was rerouted.

When should you call LG service for an IE code?

Call when the tub still will not fill after the taps, hoses, filters, pressure and drain hose all check out. LG's top-load list says that if the problem persists after its steps, the inlet valve may be malfunctioning and you should contact an LG service center ^[2]. LG's top-load IE guide says a washer that keeps showing IE will require repair service ^[3].

The inlet valve and the control board sit inside the cabinet, so testing or replacing them is a job for an LG technician. Do not open the cabinet or try to test the valve yourself.

Before you book, rule out the free fixes. LG's front-load IE page warns that even under warranty, a service visit for an IE caused by a shut-off water supply or a closed faucet will be charged, because it is not a product fault ^[4].

If you own more than one brand, the same fault has a different name elsewhere. Samsung groups 4C, 4E and nF as its "not filling" water supply error ^[6]; our Samsung washer 4C code guide covers it. Other LG washer codes have their own pages: UE for an unbalanced load and LE for a motor that cannot turn the drum. You can browse every LG appliance guide or all washer repair guides.
