LG Refrigerator: leaking water
What is this symptom?
If your LG refrigerator is leaking water, you may notice pools of water around the unit or inside the compartments. This issue can stem from common problems such as a clogged defrost drain or a faulty water supply line. Addressing these leaks promptly is essential to prevent further damage and maintain your refrigerator's efficiency.

DIY Solutions
Clear clogged defrost drain
- Unplug fridge and remove bottom shelf to access defrost drain at back of fresh food compartment.
- Pour warm water slowly into the defrost drain hole to melt ice or push debris through.
- Use a turkey baster or syringe to flush remaining debris until water drains freely to the pan underneath.
- Wipe up any residual water and replace shelf; plug in fridge and monitor leak.
Check and reseat or replace water filter
- Turn off water supply and remove old water filter.
- Inspect filter housing and filter head for cracks or improper seating.
- Install a genuine LG filter correctly by twisting/locking into place.
- Turn water supply back on and check for leaks.
Level refrigerator
- Place a level tool on top of fridge to check front-to-back and side-to-side.
- Adjust leveling legs until fridge is even and tilts slightly back-to-front for proper drain.
- Recheck after adjustment and monitor for leakage.
Clean around door gasket
- Inspect door gasket for dirt, debris, and mild mold.
- Clean gasket with warm soapy water and dry thoroughly.
