Error codegF
ApplianceRefrigerator
Where gF comes from
The flow sensor has noticed that water is not moving as expected. LG gives three triggers: a shut tap, a hose with a kink, or pressure that is off. Ice that keeps overfilling the maker can also hint that the sensor itself is failing. Refrigerators of any kind can show the code.
Steps in LG’s order
Unplug the refrigerator and let 60 seconds pass.
Reconnect it to a wall socket of its own, avoiding strips and multi-plug adapters.
Wait for the full restart, which can take up to five minutes.
Turn the tap fully open, and confirm water arrives through a hose without kinks.
Check the water pressure and, when weak, bring it up partway.
Still showing gF
A code that outlasts those steps means the refrigerator needs repair service.
Two ice-making faults sit close by
The code list has EID for the ice maker sensor and EIU for the ice maker assembly.

Plain language
What this code means
The water flow sensor reports a fault, possibly from a closed tap, a kinked hose or wrong water pressure.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
