Noticing water under or around your LG refrigerator can be alarming, but most leaks stem from simple issues you can identify and fix yourself. Whether it’s a clogged drain or a loose hose, understanding where the leak originates is key to stopping it for good.

1. Loose or Damaged Water Line

The water line supplies your fridge with water for the dispenser and ice maker. Over time, it can loosen, crack, or freeze, leading to small but persistent leaks.

How to Fix It:

• Pull the refrigerator away from the wall and inspect the water line connection.
• Tighten any loose fittings.
• If the line shows signs of damage, replace it entirely.
• For frozen lines, gently thaw with warm air from a hair dryer—never use open flame or boiling water.

Prevention Tip:
Check the water line every few months to ensure it’s secure and not kinked.

2. Clogged Defrost Drain

During the defrost cycle, your refrigerator melts frost and drains the water through a small outlet. If that drain becomes clogged with debris or ice, water can pool inside the fridge and eventually leak onto the floor.

How to Fix It:

• Locate the defrost drain (usually at the back of the freezer).
• Use warm water or a turkey baster to flush out blockages.
• Clean the drain with a mild vinegar solution to prevent future buildup.

Prevention Tip:
Regularly wipe down the back of the freezer and avoid letting spilled food or crumbs collect near vents and drains.

3. Ice Maker Leaks

The ice maker can also be a hidden source of leaks. Loose tubing, cracked fittings, or a faulty ice mold assembly may cause water to escape.

How to Fix It:

• Turn off the ice maker and observe whether the leak stops.
• If it does, check the ice maker’s water line and connections.
• Replace damaged parts or the entire ice maker if necessary.

Prevention Tip:
Inspect the ice maker hose whenever you change the water filter or move the refrigerator.

4. Water Filter Problems

An improperly installed or damaged water filter can allow water to drip down inside the fridge. This is one of the most common causes of leaks in LG models.

How to Fix It:

• Remove and reinstall the water filter, ensuring it locks firmly into place.
• If the filter is cracked, clogged, or past its replacement date, install a new OEM filter.
• Avoid using off-brand filters that may not seal properly.

Prevention Tip:
Replace the filter every six months, or sooner if your water quality is poor.

5. Cracked or Overflowing Drain Pan

The drain pan, located underneath the refrigerator, collects condensation and defrost water. If it’s cracked or overfilled, it can cause puddles beneath the unit.

How to Fix It:

• Remove the kickplate or back panel to access the drain pan.
• Empty and clean it thoroughly.
• Inspect for cracks—if damaged, replace it with a compatible part.

Prevention Tip:
Keep the area under the fridge clean and dry so you can spot any early signs of leaking.

Even a small leak can lead to floor damage or mold if ignored. By inspecting these key components—water lines, drains, and filters—you can often fix the issue quickly. Regular maintenance and cleaning will help your LG refrigerator stay leak-free and running efficiently.
