What gF
actually means.
LG links gF to its flow sensor, which measures how much water reaches the ice maker, or to low water pressure. A misreading sensor can overfill the ice maker, while low pressure gives small cubes or none.

What to do when gF shows on the ice makerKind of codeWater supply and fill
The ice maker asked for water and got too little, too slowly or none at all, or water kept arriving after the fill should have ended. A closed shutoff, a kinked line, a clogged filter and low house pressure are ruled out before the water inlet valve is replaced or the fill tube is thawed. If water is on the floor, close the supply valve before reading anything on the display.
Usually leads toIce maker water inlet valve repair
The electric valve that lets water into the ice maker, tested and replaced when it will not open, opens only partway, or keeps dripping after it should have closed.
Shows up asNo Ice Coming From the Ice Maker
The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally.

Before you book,
in this order.
Each step comes from LG's own guidance for gF on its ice makers. Follow it to the end: the last card says whether this is a visit.
Make sure the supply valve behind the unit is fully open and the line is not kinked.
If the ice maker is overfilling or spilling water, turn it off and close the supply valve.
If gF remains with good pressure, book a visit to check the flow sensor and valve.

What not to do
gF is not a filter reminder, although a badly clogged filter lowers flow too. It does not mean the ice maker assembly itself has failed.

Water supply and fill on other makes
Door ice maker
The ice maker that feeds the dispenser on the outside of a door: tucked into an insulated box in the left door of a French door model, or at the top of the freezer side of a side-by-side, with a chute and an auger carrying cubes to your glass.
Freezer ice maker
The ice maker that sits inside the freezer compartment itself, a tray that twists or a mold with a heater and an ejector, dropping cubes into a bin or drawer you open by hand, with no dispenser on the door.
In LG's own words
A gF error code indicates a flow sensor error, or low water pressure.
Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. LG models with a flow sensor on the water line.
