LG refrigerators gF error

The refrigerator detected an ice-maker water-flow sensor error or low water pressure.

gF

What this code can mean

LG associates gF with low water pressure or a flow-sensor problem, particularly when the ice maker is overfilling.

Safe first checks

  1. 1
    Check for visible water leakage or ice-maker overfilling without removing panels.
  2. 2
    Confirm the household supply valve is open and the visible supply line is not kinked.
  3. 3
    Use the model manual before making any water-pressure adjustment.

Possible causes

  • Water pressure to the refrigerator is low.
  • The ice-maker flow sensor may be malfunctioning.
  • The ice maker may be receiving too much water.
Stop conditions
  • Turn off the refrigerator water supply if overfilling or leakage continues and the valve is safely accessible.
  • Request service if the code persists or the flow sensor is suspected.

Use LG support, an authorized servicer, or a qualified plumber as appropriate for persistent pressure or overfill problems.
