What Does Error Code FE Mean on an LG Washing Machine?
Turn off the machine at the mains, locate and clean the inlet valve filter screens to remove any debris that may be holding the valve open, then restart the cycle — this resolves the majority of FE errors (takes about 15 minutes).
Fault description
Error code FE signals that your LG washing machine has detected water rising above the permitted level inside the drum. The machine's pressure sensor continuously monitors water height, and when it registers an overflow condition, the control board triggers the FE code to protect the appliance and your home from flooding.
When this error occurs, the machine will typically attempt to drain the excess water automatically before halting the cycle. You may notice the drum filling unusually high, water appearing around the door seal, or the programme stopping mid-wash. In some cases the machine will display FE shortly after the fill phase begins.
The fault is most commonly caused by a water inlet valve that is not closing fully, but a blocked pressure hose or a faulty pressure sensor can produce the same result. Most causes are straightforward to investigate at home before calling a service technician.
Causes
- Faulty or stuck water inlet valve — The inlet valve controls water flow into the drum. If the valve solenoid fails or debris holds it partially open, water continues entering even after the control board sends the signal to stop, leading directly to an overflow condition.
- Blocked or kinked pressure hose — A narrow rubber hose connects the tub to the pressure sensor. If this hose becomes blocked with detergent residue, kinked, or detached, the sensor cannot accurately read the water level and may fail to trigger the cut-off signal in time.
- Defective water level pressure sensor — The pressure sensor translates air pressure in the hose into a water-level reading for the control board. A sensor that has drifted out of calibration or failed entirely can report an incorrect level, causing the machine to overfill before the FE code is raised.
- Excessive detergent or suds — Using non-HE detergent or too much detergent generates foam that can fool the pressure sensor into reading a higher water level than actually exists. This is particularly common in households that have recently switched detergent brands.
- Control board fault — The main PCB sends the close signal to the inlet valve and interprets data from the pressure sensor. A damaged or malfunctioning board may fail to close the valve at the correct point, resulting in overfill even when all other components are working correctly.
Step-by-Step Fix
- 1
Switch off and isolate the machine
Turn the programme dial to off and switch the machine off at the wall socket. Turn off the water supply tap behind or beneath the machine. This stops any further water entering and makes it safe to investigate. Wait two minutes before proceeding.
- 2
Run a manual drain
Place a shallow tray under the filter access panel at the front bottom of the machine. Open the small drain hose, allow the water to empty into the tray, then unscrew the filter cap slowly to drain the remainder. This removes the excess water before you begin checking components.
- 3
Inspect and clean the inlet valve filter screens
Disconnect the cold water supply hose from the back of the machine. Inside the inlet valve connection you will find small mesh filter screens. Remove them carefully with needle-nose pliers and rinse under running water to clear any sediment or scale. Refit the screens and reconnect the hose, ensuring the connection is hand-tight plus a quarter turn.
- 4
Check the pressure hose for blockages or kinks
The pressure hose runs from a port on the side of the tub up to the pressure sensor, usually mounted near the top of the machine cabinet. Trace the hose visually and feel along its length for kinks or collapsed sections. Disconnect each end and blow gently through it — if air passes freely it is clear. If blocked, soak in warm water to dissolve residue and refit securely.
- 5
Reduce detergent and run a drum-clean cycle
If you have been using non-HE detergent or a generous measure, switch to an HE-rated product and use the dose recommended on the packaging for your water hardness. Run the machine's drum-clean or tub-clean programme without laundry to flush out residual suds and detergent build-up that may be affecting the pressure sensor reading.
- 6
Test the inlet valve operation
Restore the water supply and power, then start a short wash cycle. Watch the drum during the fill phase — if water continues rising after the machine should have stopped filling, the inlet valve is not closing correctly and will need to be replaced. Note the point in the cycle at which FE reappears, as this information will help a service technician diagnose the fault quickly.
- 7
Reset the machine and retest
If the above steps have not revealed an obvious fault, perform a full reset by unplugging the machine for five minutes, then plugging back in and selecting a fresh cycle. If FE returns immediately or during the fill phase, the pressure sensor or control board is the likely cause and professional diagnosis is recommended.

When to call a service technician
Contact a service technician if the machine continues to overfill after you have cleaned the inlet valve filters and confirmed the pressure hose is clear and correctly connected. A valve that allows water to trickle in even when the machine is switched off, or a pressure sensor that cannot be cleared by resetting, requires component-level testing with a multimeter that goes beyond typical DIY scope.
You should also seek professional help if you notice water pooling beneath the machine, signs of electrical burning near the control panel, or if the FE code appears instantly every time power is restored. These symptoms suggest a control board fault that carries a risk of further damage if the machine continues to be operated.

Frequently Asked Questions
Is it safe to leave the machine while it shows error code FE?
No. An FE error means water may be at or above the safe level in the drum. Switch the machine off at the mains and turn off the water supply tap immediately. Leave the door closed until you have drained the machine via the filter access panel at the front, as opening the door with a very full drum can cause a significant water spill.
Can too much detergent really cause an FE error on an LG washing machine?
Yes, it is a genuine cause. Excess foam generated by non-HE or overdosed detergent can compress the air column in the pressure hose, causing the sensor to register a falsely high water level. Switching to an HE detergent and running a drum-clean cycle often resolves FE errors that appear intermittently with no obvious mechanical fault.
How do I know if the inlet valve needs replacing rather than just cleaning?
If water continues to enter the drum slowly even when the machine is switched off at the programme dial but still connected to the water supply, the valve diaphragm has failed and cleaning will not fix it. A valve that passes water when it should be closed must be replaced. This is a relatively low-cost part available for all models in the LG F-series range listed above.
Will the FE error clear itself once the water drains down?
The machine will attempt to drain excess water automatically and may clear the code temporarily, but if the underlying cause — such as a faulty inlet valve — has not been addressed, the error will return on the next fill cycle. Always investigate and resolve the root cause rather than relying on the auto-drain to manage the symptom.
Does error code FE affect all LG washing machine models the same way?
The FE code has the same meaning across all affected LG models including the F1056, F1068, F1073, F1091 and F1096 series — water level has exceeded the safe threshold. The location of the pressure sensor and inlet valve varies slightly between models, so consult your specific model's service diagram if you are unsure where to find these components inside the cabinet.
