# How to Fix LG Error FE (Overflow Error)
## What Does LG Error Code “FE” Mean?
The “FE” error code on an LG washing machine stands for **”Forced End”** or **”Filling Error.”** In simple terms, your machine has detected an abnormal water level inside the drum that is higher than programmed limits. This is often referred to as an **Overflow Error**.
When the machine tries to fill and the water level sensor (the pressure switch) doesn’t detect the correct levels—or detects levels that are too high—it triggers the FE error to prevent flooding.

## Step-by-Step Troubleshooting Guide
The vast majority of FE errors are caused by a malfunctioning **Water Inlet Valve** that is stuck open and continuously allowing water into the drum, even when the machine is turned off.
Use the following steps to diagnose and resolve the issue, starting with the easiest checks.
### Step 1: Drain the Water and Reset the Machine (The Quick Fix)
Before attempting a repair, try draining the machine and clearing the error from the control board.
1. **Unplug the Machine:** Disconnect the washing machine from the power outlet immediately.
2. **Drain Manually:** Use the drain hose or the lower filter access point (depending on your model) to manually drain the excess water out of the drum into buckets or a floor drain.
3. **Wait 5 Minutes:** Leave the machine unplugged for five minutes to allow the control board to fully reset.
4. **Test Run:** Plug the machine back in and run a short rinse/spin cycle. If the machine fills correctly and completes the cycle, the error may have been temporary. If the error returns, proceed to Step 2.
### Step 2: Test the Water Inlet Valve (The Likely Culprit)
The inlet valve controls the flow of hot and cold water into the machine. If one of the internal solenoids fails, the valve can remain partially or fully open, leading to an overflow.
1. **Check for Residual Filling:** With the machine **unplugged and turned off**, open the door and check the drum. If you see water slowly pooling or dripping into the tub, the inlet valve is failing and needs replacement.
2. **Listen for Noise (Advanced):** If you are comfortable accessing the machine’s back panel (ensure it is unplugged first), you can remove the hose connections and visually inspect the valve. A humming or buzzing sound when the machine is off is another indicator that the solenoid is attempting to close but failing.
> **Diagnosis:** If the machine continues to fill with water while it is off or unplugged, the Water Inlet Valve is defective.
### Step 3: Inspect the Pressure Switch/Hose (The Secondary Cause)
The pressure switch (or water level sensor) is responsible for telling the control board how much water is actually in the tub. If the switch or its connecting hose is blocked, it can misread the water level.
1. **Locate the Pressure Switch:** On most LG models, this circular sensor is located near the top of the tub, often connected to the control board via wiring.
2. **Inspect the Pressure Hose:** A thin rubber tube connects the pressure switch to a port at the bottom of the tub. Disconnect this hose from both ends.
3. **Clear Blockages:** Look inside the hose for clogs, detergent buildup, or debris. You can gently blow through the hose to ensure it is completely clear.
4. **Check the Port:** Ensure the air trap (the port where the hose connects to the tub) is also clear.
### Step 4: Check for Detergent Overuse (Sudsing)
Excessive detergent use, particularly high-sudsing standard detergent in an HE (High-Efficiency) machine, can cause a suds lock. The large volume of foam can push the water level sensor incorrectly, triggering the overflow error.
1. **Reduce Detergent:** If you suspect this is the issue, run several empty rinse cycles using the hottest water setting to clear any remaining soap residue from the drum and lines.
2. **Use HE Detergent:** Ensure you are always using HE (High-Efficiency) detergent, and use only the amount recommended by the manufacturer.

## Final Resolution
If you have confirmed that water continues to enter the drum even when the machine is powered down and unplugged, you must replace the Water Inlet Valve. This is a crucial safety component designed to prevent flooding.
