LG Washer FE Error Code: Causes and 7 Proven Fixes (2026)

The LG washer FE error code means the machine has detected too much water in the tub and stopped the cycle as a safety measure. In most cases the cause is a water inlet valve stuck open, a faulty water level sensor, or too many suds. Turn off both water taps first, then use this guide to drain the washer and find the cause.

Quick Fix: LG Washer FE Error Code at a Glance

1. Turn off the hot and cold water taps.
2. Power the washer on, press Spin Speed until No Spin is selected, then press Start/Pause to drain.
3. Unplug the washer for 5 to 10 minutes to reset it.
4. Check for excess suds and run a rinse and spin with no detergent if you find any.
5. With the washer unplugged, turn on one tap at a time. If water enters the tub, the inlet valve is stuck open and needs replacing.

What Does the LG Washer FE Error Code Mean?

FE is an overfill error. Your washer uses a pressure sensor to measure the water level in the tub. When the level goes above what the cycle expects, the control board displays the LG washer FE error code and stops the cycle.

Some websites describe FE as a low water or “not filling” problem. That’s incorrect. A washer that can’t fill usually shows IE, and one that can’t drain shows OE. FE is the opposite of a fill problem: there’s too much water, not too little.

Common Symptoms That Come With the FE Code

The LG washer FE error code rarely shows up alone. You may notice:

• FE on the display, with the cycle stopped
• The drain pump running on its own, sometimes continuously
• Water in the tub even though the washer isn’t running
• Heavy foam when you open the door
• Water still entering the machine after the cycle has stopped

If water keeps coming in with the machine off, treat it as urgent. That points straight at the inlet valve.

What Causes the LG Washer FE Error Code?

There are five common causes, listed roughly from most to least likely.

A Water Inlet Valve Stuck Open

The inlet valve is where your hot and cold hoses connect at the back of the washer. It opens to let water in and closes when the tub is full. If its internal diaphragm or solenoid fails, or debris keeps it from sealing, it can let water through after the washer has told it to stop.

This is a very common cause of the LG washer FE error code. The telltale sign is water entering the tub while the machine is off.

A Faulty Pressure Switch

The pressure switch tells the control board how full the tub is. If it fails, the board gets a wrong reading. It may think the tub is overfull, or it may never receive a proper “full” signal and keep filling.

A Blocked, Kinked, or Loose Pressure Hose

A small clear hose runs from the bottom of the tub to the pressure switch. As water rises, air pressure in the hose changes, and that is how the sensor reads the level. A cracked, pinched, clogged, or disconnected hose gives false readings.

Too Much Detergent or the Wrong Type

Excess suds can travel up the pressure hose and make the sensor think the tub is overfull. This happens when you use too much detergent, or regular detergent in a front-loader that needs a high-efficiency (HE) formula. It’s the easiest cause to fix, so check it early.

A Control Board Fault

Less often, a failed relay on the main control board keeps powering the inlet valve so it never closes. This is the least common cause and should be your last suspect, not your first.

A slow or blocked drain can sometimes confuse level readings too, so the drain hose and filter are worth a quick look.

Safety First: Stop the Water Before You Troubleshoot

If the washer is still filling or you see water around the base:

1. Turn off both water taps behind the washer.
2. Unplug the washer if there’s any sign of leaking or flooding.
3. Put towels down around the base to catch spilled water.

Water and electricity don’t mix, so don’t skip this step. Once the taps are off, you can work through the fixes without rushing.

How to Drain the Washer After the FE Code Appears

Get the extra water out before you start diagnosing. LG’s own guidance for an overfill code goes like this:

1. Make sure both water taps are closed.
2. Power the washer on.
3. Press Spin Speed until No Spin is selected.
4. Press Start/Pause.

The washer should drain the water. Button names vary a little between models, so check your manual if yours looks different. If the washer won’t power on or drain, use the small drain hose behind the service cover at the bottom front of the machine and empty the water into a shallow pan.

How to Fix the LG Washer FE Error Code Step by Step

Step 1: Reset the Washer

Unplug the washer for 5 to 10 minutes. This resets the control board and can clear a one-off sensor glitch. Plug it back in, open the taps, and run a short cycle to see whether the error returns.

If it comes back quickly, keep going.

Step 2: Check for Suds

Open the door and look for foam. If there’s a lot, run a rinse and spin with no detergent to clear it out. From then on, use a smaller amount of HE detergent measured for your load size.

If the error doesn’t return, you’ve found the problem. In front-loaders, repeat cases of the LG washer FE error code often trace back to overdosing detergent.

Step 3: Test the Water Inlet Valve

This is the most useful check for the LG washer FE error code, because a stuck valve is such a common culprit.

1. Unplug the washer and make sure the tub is empty.
2. Turn on one tap at a time, hot first, then cold.
3. Watch and listen for water entering the tub with the power off.

If water flows in, the valve is stuck open and needs replacing. Turn the tap off again right away and don’t run the machine in this condition.

Replacing an inlet valve is manageable on many models if you’re comfortable with basic appliance work. Unplug the washer, close the taps, and photograph the wiring before you disconnect anything. If you’re not confident, call a technician.

Step 4: Check the Pressure Hose

With the washer unplugged, find the pressure switch (usually near the top of the machine) and follow the small clear hose down toward the tub. Look for:

• Cracks or splits
• A hose that has slipped off the switch or the tub fitting
• Kinks or pinching
• Water, soap, or debris inside

Reattach a loose hose firmly and straighten any kinks. If the hose is damaged, replace it. A clogged one can sometimes be cleared, but replacement is usually inexpensive and more reliable.

Step 5: Inspect the Drain Hose and Filter

Make sure the drain hose isn’t kinked and is seated correctly in the standpipe. Then clean the drain pump filter at the front bottom of the machine. Put a shallow tray and towels underneath first, because water will come out. Turn the cap counterclockwise, remove any lint, coins, or debris, rinse the filter, and screw it back in tightly.

A blocked drain more often triggers OE, but this is a quick check and can rule out a secondary factor.

Step 6: Run a Test Cycle

Reconnect everything, open the taps, and run a short cycle. Watch the first few minutes of filling. The washer should fill to the expected level and stop. If the LG washer FE error code returns after all of the above, the pressure switch or control board likely needs proper testing.

Common Mistakes With the LG Washer FE Error Code

• Running more cycles to “see if it clears.” Overfilling can leak onto your floor.
• Assuming it’s a fill problem. FE means too much water, so checking for a clogged inlet filter won’t help.
• Replacing the control board first. It’s the least likely cause and the most expensive part.
• Ignoring suds. It’s the cheapest fix, yet it’s often skipped.
• Guessing at parts. Swapping parts without testing can cost you money and time.

When to Call a Technician

Call a professional if:

• Water enters the washer while it’s unplugged and you’d rather not replace the valve yourself
• You’ve replaced the inlet valve and FE still appears
• The pressure hose looks fine but the error keeps returning
• The washer fills endlessly or the drain pump runs constantly after a reset
• You suspect a control board or wiring problem

Pressure switch and control board faults need electrical testing with a multimeter. A technician can usually pinpoint the cause in one visit. If your washer is still under warranty, contact LG support before opening the machine.

Can You Keep Using the Washer With the LG Washer FE Error Code?

No. FE is a safety stop. Running more cycles risks overflow, water damage to your floor, and harm to the washer itself. If water reaches electrical parts, it’s a safety hazard too. Keep the taps off and fix the cause before your next load.

How to Prevent the LG Washer FE Error Code From Coming Back

• Use HE detergent in front-loaders and measure it for each load.
• Avoid overloading the drum.
• Clean the drain filter every few months so lint doesn’t build up.
• Turn the taps off when you’re away for a long time, which limits damage if a valve fails.
• Replace hoses that show cracks or bulges.

LG Washer FE Error Code FAQs

What does the LG washer FE error code mean?
It means the washer has detected an overfill. There’s more water in the tub than the cycle expects, so the machine stops as a precaution.

How do I reset the LG washer FE error code?
Turn off the taps, unplug the washer for 5 to 10 minutes, then plug it back in and run a drain cycle (No Spin, then Start/Pause). If the code returns, the cause is still there.

Is a bad inlet valve behind the LG washer FE error code?
Often, yes. Turn on a tap with the washer unplugged. If water enters the tub, the valve is stuck open.

Can too much detergent cause the FE error?
Yes. Excess suds can make the pressure sensor read a higher level than the real one. Run a no-detergent rinse and use less HE detergent next time.

Will the LG washer FE error code go away on its own?
A power reset can clear a temporary glitch. If the real problem is a stuck valve or faulty sensor, the code will come back.

Is it safe to keep running the washer with FE?
No. Keep the taps off and don’t run more cycles until you’ve found the cause.

Final Thoughts on the LG Washer FE Error Code

The LG washer FE error code looks alarming, but it’s a protective feature, and the fix is often simple. Stop the water, drain the tub, then work through suds, the inlet valve, and the pressure hose. If the inlet valve fails the tap test, replacing it usually solves the problem. If the error keeps returning, have a technician test the pressure switch and control board before you buy any more parts.
