The FE error code on a Samsung washing machine indicates an **overflow or overfill condition**—your washer is detecting too much water and won't stop filling as a safety measure to prevent flooding. Here’s a detailed guide to understanding and solving this problem.
## ???? First: Safety First
**Before doing anything else, turn off the water supply valves to the washer and unplug the machine.** This stops any further water flow and eliminates electrical risk while you troubleshoot.
## ???? What Does the FE Error Code Mean?
FE stands for **Flood Error** or **Overflow Error**. Your washer has a pressure sensor (also called a water level sensor) that tells the control board how much water is in the drum. When the sensor detects water levels above a safe threshold—or if the sensor itself malfunctions—the machine triggers the FE code and may continuously fill or continually try to drain.
The error can stem from:
- **A stuck water inlet valve** (letting water in even when turned off)
- **A clogged or failed pressure sensor / hose**
- **A faulty control board** (rare, but possible)
## ????️ Step-by-Step Troubleshooting Guide
### 1. Perform a Hard Reset
Sometimes a temporary electronic glitch causes false error codes.
- Unplug the washer from the power outlet.
- **Wait 5–10 minutes** to allow the control board capacitors to discharge.
- Plug the washer back in and run a short cycle (like Rinse & Spin) to see if the error returns.
- *Note:* A reset only clears the display; it doesn't fix mechanical failures. If the FE code reappears, move to the next steps.
### 2. Check the Water Inlet Valve
This is the most common physical cause of an FE error. The inlet valve opens to let water in and should close tightly when power is cut.
- **Visual Inspection:** Locate the valve where the fill hoses connect to the washer. Look for leaks, corrosion, or mineral buildup.
- **The "Power Off" Test:** With the washer unplugged but the **water supply still on**, listen carefully. If you hear water flowing or see the drum filling, the valve is stuck open and must be replaced.
- **Clean the Inlet Screens:** Turn off the water supply, disconnect the fill hoses, and find the small mesh screens inside the valve ports. Debris or sediment can block them, causing erratic filling. Clean gently with a toothbrush and reattach.
### 3. Inspect the Pressure Sensor System
The pressure sensor (or pressure switch) is a small round device with a clear plastic hose attached to it. This hose connects to the outer tub and measures water level by air pressure.
- **Locate It:** Typically found near the top corner of the washer behind the control panel.
- **Check the Hose:** Disconnect the hose from the sensor and the tub. Blow gently through it to ensure it's not clogged with soap scum or mold. A clog here traps air and fools the sensor into thinking water is low—so the washer keeps filling.
- **Check for Kinks or Punctures:** Even a tiny hole can alter pressure readings. Replace the hose if damaged.
- **Test the Switch:** With the hose clear, gently blow into the pressure switch itself. You should hear an audible *click* from the switch engaging. No click usually means a faulty sensor needing replacement.
### 4. Rule Out Drain and Siphoning Issues
Improper drain installation can create a siphon, pulling water back into the machine even when it's not filling.
- Check that the drain hose is not inserted more than **6–8 inches** into the standpipe.
- Ensure the drain hose has a **high loop** (the highest point should be above the water level of the machine) to prevent backflow.
- Look for kinks or blockages in the drain hose that could cause water to flow the wrong way.
### 5. Recognize When It's the Control Board
If the washer continues to fill **even when turned off and unplugged**, the main control board (PCB) has likely failed. A shorted relay on the board can physically stick in the "open" position, sending constant power to the inlet valve. **This is a fire and flood risk** and requires professional board replacement.
## ✅ When to Call a Professional
If you have performed the checks above—especially verifying the inlet valve is not stuck open, clearing the pressure hose, and performing a hard reset—and the FE error persists, it is time to call for service.
- Replacing a water inlet valve is moderate DIY, but requires disconnecting water and electrical safely.
- Pressure sensor replacement and control board repairs are best left to certified technicians.
- **If your unit is under warranty, contact Samsung Support directly** before attempting any part replacement.
As Samsung's official support site notes, "If the washer continuously fills with water, turn off the water valves and visit our Support Center to request service". Do not repeatedly run the machine in this state, as it can flood your home and damage the washer's motor and electronics.
