    LG refrigerator error codes - Text saying [Er(E) FF/F] appears on the display

    Troubleshooting

    In refrigerators with water purifying functions, the UF type filter does not remove useful minerals (calcium, magnesium, etc.) from the water.
    However, because of such mineral components, white mineral deposits are formed when water evaporates or freezes.
    This is the same phenomenon that occurs when heating or freezing spring water (such as Samdasoo spring water).
    Mineral components remain just as particles in ice or cold water and then melt naturally when the ice melts and the water gets warmer.
    Minerals such as calcium and magnesium are always present in tap water, spring water, and underground water, and are harmless to the human body.

    Try this

    Are there any white deposits around the outlet?

    When fine pieces of ice or purified water on the outlet evaporate, the mineral components dry white and adhere to the appliance.
    There may be white deposits around the outlet, which are harmless to the human body.
    If there are white mineral deposits, wipe them away with a clean, lint-free cloth.
    Except in cases of disassembly and reassembly for simply cleaning away mineral deposits, it is necessary to have it checked by a service technician through a visit.
