How to Fix / Troubleshooting

Safety: Unplug the refrigerator and shut off the water supply before working on water lines.

  • Identify source: Remove the toe grille and inspect for water around the drain pan, filter housing, and water lines.
  • Check defrost drain: Access the freezer rear panel, locate the drain hole under the evaporator, and clear any ice or debris with warm water and a turkey baster.
  • Inspect tubing: Follow plastic water lines from the inlet valve to the filter and dispenser. Tighten push-in fittings and replace any cracked tubing.
  • Filter check: Ensure the LG water filter is fully seated and the filter head is not cracked. Replace if leaking.
