What FE means (lg fe error)
An lg fe error means an LG washer has detected an overfill — the water level is rising above the expected point. The control raises FE and usually drains for safety, which points to an inlet valve that is not closing fully or a level sensor reading incorrectly.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your LG Washer. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “FE”
- The washer overfills or keeps filling
- The unit drains automatically to protect itself
- Filling continues even when the cycle is paused
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct LG parts.
- Inlet valve stuck open — the valve does not close fully
- Level sensor fault — the pressure sensor misreads the level
- Pressure hose problem — a kinked or disconnected sensor hose
- Control fault — the board mismanages the fill
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Turn off the water supply taps to stop further filling.
- Power the washer off at the breaker for several minutes, then restore.
- Note whether water keeps entering even with the cycle stopped.
- Because an overfill can leak, arrange service if FE returns.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the water inlet valve, water level pressure sensor, and control board. The correct part for your LG Washer is matched from the model and serial number, and genuine LG components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
FE needs a technician to test the inlet valve and water-level pressure sensor and replace whichever is at fault. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your LG Washer. Keep filters, vents, and the condenser or exhaust path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the LG maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in or laundry installation done to LG specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
