LG Refrigerator Error Code Er gF
The flow meter that measures water for the dispenser and ice maker is reading wrong, most often because of supply problems. Check the tap is fully open and the line is not kinked first.
Also shown as: E gF, gF
Common causes
- Water supply tap partly closed, or household water pressure too low or too high
- Water line kinked or pinched behind the refrigerator
- Clogged water filter restricting the flow
- Flow meter (flow sensor) failed
What to check, in order
- Make sure the water supply tap on the wall behind the refrigerator is fully open
- Pull the refrigerator forward carefully and check the water line is not kinked or crushed
- Replace the water filter if it is overdue, then dispense a few glasses of water to purge air
- Unplug the refrigerator for 60 seconds, restart it and dispense water again to see whether the code returns
- If supply, hose and pressure are all good, the flow sensor itself has failed and needs replacing
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code Er gF, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
