LG Washer FE Error Code: What It Means & What to Check
If your LG washer is showing FE, it typically indicates an overfill / too much water detected condition. In other words, the washer believes the water level is rising above where it should, or it’s seeing abnormal water level behavior during fill.
This is one error where it’s smart to act quickly, because true overfilling can lead to leaks and water damage. Start with the immediate safety steps first, then work through the quick checks below.
What FE usually means on an LG washer
FE commonly means “fill error (overfill)” on many LG washers. The washer monitors water level through a pressure sensor system. If it sees the level go too high — or it thinks water is entering when it shouldn’t — it may stop, drain, and display FE.
Do this first (to prevent water damage)
- Stop the cycle if it’s running.
- Turn off both water supply valves at the wall (hot and cold).
- If the tub is very full or the washer is leaking, unplug the washer (or turn off the breaker).
- Dry up standing water and keep it away from outlets/power strips.
Quick checks you can do at home
1) Check if it keeps filling even when the washer is off
With the washer off (and ideally paused), see if water is still entering. If it continues to fill when it shouldn’t, that strongly suggests a stuck-open inlet valve. Keep the wall valves off and schedule service.
2) Verify the drain hose isn’t causing siphoning or weird level behavior
An incorrectly installed drain hose can cause odd filling/draining behavior that confuses water level sensing.
- Make sure the drain hose isn’t sealed airtight in the standpipe (it needs an air gap).
- Don’t push the drain hose too far down into the standpipe.
- Ensure the standpipe height and routing are normal (not extremely low).
3) Confirm the drain isn’t restricted
If the washer can’t drain properly, water level can rise higher than normal during certain steps. If you hear the drain pump running but the tub stays full, that’s a clue.
4) Power reset (after the situation is stable)
- With the water valves off, unplug the washer (or turn off breaker) for 2–5 minutes.
- Restore power, turn the valves back on, and monitor the next fill closely.
If FE returns quickly or the washer starts overfilling again, shut the valves back off and call for service.
Most common causes of LG FE
- Inlet valve stuck open (water keeps entering when it shouldn’t)
- Pressure sensor / water level sensing problem
- Air trap/pressure hose issue (clogged, loose, pinched, or leaking air)
- Drain hose installation causing siphoning or abnormal level behavior
- Main control board not controlling fill correctly (less common)
Likely parts involved (when it needs service)
- Water inlet valve
- Pressure sensor / water level sensor
- Air trap and pressure hose (and related connections)
- Main control board (less common)
When to call Beacon
Call for service if:
- The washer appears to fill even when it’s turned off
- FE returns quickly after a reset and careful restart
- You see repeated overfilling, leaking, or water around/under the washer
- You want the inlet valves and pressure sensor tested before replacing parts
Our friendly technicians in yellow can test the inlet valve(s), verify pressure sensor readings, inspect the air trap/pressure hose system, and correct the root cause safely.
