LG Washer FE Error Code: What It Means and How to Fix It
Updated · from manufacturer service documentation
The FE code on an LG washer means Overflow Error — the machine detected too much water and stopped. Unlike most other LG error codes, FE is documented to permanently shut the washer off rather than allow a restart, so this one needs the cause fixed before the machine will run again.
What Causes the FE Code
| Cause | Likelihood | DIY difficulty | Related part |
|---|---|---|---|
| Air chamber or tube clogged | Most common | Easy — clean air chamber/tube | Air chamber |
| Water level frequency reading over 21.0 kHz in service mode | Less common | Moderate — service mode test | Pressure switch / sensing |
How to Fix the FE Error, Step by Step
-
Check the air chamber and tube for clogs
This is the first documented check for FE — clear any foreign material blocking the air chamber or its tube.
-
Check the water level frequency in service mode
If entering service mode shows a water level frequency over 21.0 kHz, that confirms the overflow condition is being read correctly by the sensing system rather than being a false alarm.
-
Know that FE won't just clear itself with a restart
Per LG's training documentation, "in the event of an FE error code, the machine will be turned off and will not be restarted" — unlike most other codes, you need to physically address the overflow condition before the washer will run again.
Which Models This Applies To
Documented for the LG WT5070C service manual (air chamber/frequency diagnostic) and the WM0742HGA training manual (permanent-shutoff behavior). FE sits alongside PE (pressure sensor error) in LG's documentation as a related but distinct water-level fault — PE points to the pressure sensor itself, while FE specifically means an overflow condition was detected.

Frequently Asked Questions
Can I just restart the washer to clear an FE code?
No — per LG's own training documentation, FE turns the machine off and it will not restart on its own. You need to find and fix the overflow cause first.
What's the first thing to check for an FE code?
The air chamber and its tube for clogs or foreign material — this is the documented first step before anything else.
Is FE the same as PE on an LG washer?
No — they're related water-level faults but distinct. FE means an overflow was detected; PE points to the pressure sensor/switch itself being disconnected or out of range.
How do I know if the overflow reading is real or a false alarm?
In service mode, check the water level frequency — a reading over 21.0 kHz confirms the overflow condition is being sensed correctly.
