LG Washing Machine Error Code FE — Overfill / Water Overflow

Stop the Cycle Now Water is overflowing — act immediately

Quick Answer

The LG washing machine error code FE means the washer has detected water overfilling the drum beyond the safe maximum level. The machine stops the cycle to prevent flooding. Turn off the water supply valves behind the washer immediately. The most common cause is a stuck-open water inlet valve that keeps letting water in even after the drum is full. This is not a DIY repair — a failed inlet valve requires a technician to replace.

What Does LG Washing Machine Error Code FE Mean?

The LG washing machine error code FE is an overfill error that indicates the water level inside the drum has risen above the maximum safe threshold. "FE" stands for Fill Error (overflow). The washer's water level sensor monitors fill height continuously. When it detects water above the programmed limit, it immediately halts the cycle and displays FE to prevent the drum from overflowing onto the floor.

Unlike IE (not enough water) or OE (water not draining), FE is the opposite problem: too much water is entering the drum and not stopping. This means something in the fill control system has failed. The water inlet valve is the most common culprit — when its solenoid sticks open, water flows continuously into the drum regardless of what the control board signals.

FE is one of the more urgent LG washing machine error codes because an overfilling washer can flood your laundry room quickly. The immediate priority is stopping more water from entering. The root cause then needs a technician to diagnose and fix properly. Promix Appliance Repair provides same-day appliance repair across Boston and the full MetroWest area for exactly this type of situation.

Why Your LG Washing Machine Shows Error Code FE

Stuck-open water inlet valve. The solenoid valve that controls water entry fails in the open position, allowing water to flow into the drum continuously even when the control board sends the "stop" signal. Most common

Faulty water level sensor (pressure switch). The sensor responsible for reporting the drum's water level sends an incorrect reading, causing the control board to keep filling past the safe limit because it thinks the drum is not yet full. Common

Blocked or kinked pressure sensor hose. The small tube connecting the water level sensor to the drum is pinched or clogged with residue, preventing an accurate pressure reading and causing the sensor to under-report the water level. Occasional

Control board fault. A failed relay or component on the main control board keeps the inlet valve circuit energized even when it should close, resulting in continuous overfill. Less common

Siphoning from an incorrectly routed drain hose. If the drain hose is submerged too deep in the standpipe, a siphoning effect can occur that pulls water back in unexpectedly, triggering a false FE reading in some configurations. Rare

How to Respond to LG Washing Machine Error Code FE — Step by Step

Turn off both water supply valves immediately

Go to the wall behind the washer and turn both the hot and cold supply valves fully clockwise to close them. This stops more water from entering the drum. Do this before anything else — do not wait.

Important: If you cannot reach the valves quickly, shut off the main household water supply instead. Preventing further flooding is the top priority.

Power off and unplug the washer

Press the power button to cancel the cycle, then unplug the machine from the wall outlet or trip its circuit breaker. This cuts power to the inlet valve solenoid so it cannot continue drawing water even if it was stuck open.

Check for water on the floor and address any overflow

Look around and under the washer for standing water. Place towels or use a mop to contain the water before it reaches flooring, baseboards, or adjacent rooms. If there is significant flooding, consider calling a water damage service.

Run a manual drain cycle once power is restored

Plug the washer back in and select the Drain and Spin cycle only — do not open the supply valves yet. This empties excess water from the drum so you can safely open the door and remove the laundry.

Note: Keep the supply valves closed during this step. The machine only needs power to run the drain pump — it does not need the water supply.

Check the pressure sensor hose (visual inspection only)

If you are comfortable pulling the washer out, look at the small rubber or plastic hose that runs from near the drum up to the water level sensor. Check for any visible kinks, splits, or disconnected ends. Do not attempt to remove or reconnect internal components yourself.

Do not reopen the supply valves until a technician has inspected the machine

If FE appeared once and the drain cycle completed normally, leave the supply valves closed and book a technician. Running another cycle with valves open risks a repeat overfill. The stuck inlet valve or faulty sensor must be replaced before the machine is used again.

FE is caused by an internal component failure in all but the rarest cases. There is no DIY fix that resolves the root cause. After stopping the overflow and draining the drum, book a technician before using the washer again.

When to Call a Technician

FE almost always requires professional repair. Call a technician as soon as you have stopped the water and drained the drum, if any of these apply:

Water continued entering the drum even after the washer displayed FE and stopped the cycle — the inlet valve is almost certainly stuck open
FE reappears the moment you restart a cycle with the supply valves open
There is visible water on the floor around or under the machine
The drum was completely full of water when FE appeared — excess water may have entered the motor or electronics
The error appeared on the very first use after installation — the inlet valve or sensor may have been defective from the start

How Promix Repairs LG Washing Machine FE Errors

When a Promix Appliance Repair technician arrives for an LG washing machine FE call, the first step is a controlled fill test with the machine monitored closely to observe whether the inlet valve closes on command. The technician also checks the water level sensor output and inspects the pressure sensor hose for blockage or disconnection. This narrows the fault to the inlet valve, the sensor, or the control board within the first 10 to 15 minutes.

In most FE cases the water inlet valve has failed and needs replacement. Promix technicians carry common LG inlet valve assemblies on the truck, which means the repair is often completed the same day without a return visit. If the water level sensor or control board is the cause, parts are sourced quickly and installed with a full warranty on both parts and labor. Promix Appliance Repair has over 10 years of experience with LG appliance repair across Boston and MetroWest. The service call fee is credited in full toward your repair if you proceed. There is no surprise markup. You hear the price before any work begins.

Water level sensor repairs are generally less expensive than inlet valve replacement. Control board faults vary widely depending on which component has failed.

Because FE can have more than one root cause, an accurate price is only possible after a live diagnostic. Call (781) 666-9565 for a transparent quote before any work begins.

How to Prevent LG Error Code FE From Coming Back

✓

Turn off the supply valves when the washer is not in use. This is the single most effective prevention. A stuck-open inlet valve cannot overfill the drum if the household water supply is closed between cycles.

✓

Do not leave a running washer unattended for long periods. FE happens fast. If you stay nearby during the first few minutes of a fill cycle, you can catch any overflow before it causes floor or cabinet damage.

✓

Keep the pressure sensor hose clear of residue. Run the Tub Clean cycle monthly. Detergent buildup can coat the small tube that feeds pressure readings to the water level sensor and cause it to under-report fill height over time.

✓

Use HE detergent in the correct amount. Excess suds create foam that the pressure sensor can misread as water, leading the control board to add more water than the cycle requires.

✓

Consider an automatic water shutoff device. Leak detectors placed behind the washer can cut the water supply automatically if they sense moisture on the floor, limiting damage if FE occurs again before the valve is replaced.

Frequently Asked Questions

Can I keep using my LG washing machine with error code FE?

No. FE means the washer overfilled and stopped to prevent flooding. Using the machine again with the supply valves open risks a repeat overfill that can cause water damage to your floor, cabinets, and the washer itself. Keep the supply valves closed and book a repair before running another cycle.

Will resetting my LG washing machine clear error code FE?

A power reset will clear the displayed code, but FE will return immediately the next time the washer tries to fill if the inlet valve or sensor has not been fixed. A reset does not repair the stuck valve or faulty sensor. It is useful only for draining the drum after the supply is closed.

How long does it take to fix LG error code FE?

If the cause is a failed water inlet valve, a Promix technician can typically complete the replacement in 60 to 90 minutes during the same visit. Promix carries common LG inlet valve parts on the truck. If the water level sensor or control board is at fault, repair time depends on parts availability but is usually resolved within one to two visits.

Is LG error code FE covered under warranty?

A stuck-open inlet valve or a defective water level sensor are manufacturing defects that LG's standard limited warranty covers if the washer is within the warranty period. Check your warranty documentation or contact LG to confirm coverage for your specific model and purchase date.

Is FE dangerous — can the washer flood my home?

It can, which is why acting quickly matters. The washer stops the cycle when FE fires, but if the inlet valve is stuck open it may continue letting water in even with the cycle stopped. Closing the supply valves behind the machine immediately prevents any further water entry. If there is already water on the floor, address it quickly to avoid damage to flooring, baseboards, and the subfloor.

What is the difference between LG error codes FE and IE?

IE (Inlet Error) means the washer is not receiving enough water and the drum is underfilling. FE (Fill Error) is the opposite — the drum is receiving too much water and overfilling. IE is usually a simple supply issue you can fix yourself. FE almost always requires a technician because the cause is a stuck-open valve or a failed sensor inside the machine.
