LG Refrigerators Leaking Water on Floor: How to Fix It Yourself
An LG fridge leaking water on the floor is most commonly caused by a clogged defrost drain. When the drain clogs with ice or debris, defrost water overflows from the freezer and pools under or in front of the fridge. Clearing the drain takes about 15 minutes.
⚠️ Safety First
- Clean up standing water immediately to prevent floor damage.
- Unplug the fridge if you need to access components behind it.

Step-by-Step Repair
- 1
Locate the source of the leak
Check where the water is coming from. Water under the front usually means a clogged defrost drain. Water at the back means a drip pan overflow or water line leak. Water inside the fridge on shelves usually means a clogged drain inside the fresh food section.
- 2
Clear the defrost drain
Remove the freezer back panel (unscrew it). Find the drain hole at the bottom of the evaporator compartment. It is often clogged with ice. Pour warm water into the drain using a turkey baster to melt the ice clog. Use a pipe cleaner to clear any remaining debris.
- 3
Check the drain tube below
Pull the fridge out and locate the drain tube at the back bottom. It should lead to a drip pan. Make sure the tube is not kinked or disconnected. Flush water through it from above to confirm it flows freely into the pan.
- 4
Inspect the drip pan
The drip pan sits underneath the fridge near the compressor. Slide it out and empty it if it is full. Normally the water evaporates from the heat of the compressor, but if the pan is cracked or overflowing, water ends up on the floor. Clean the pan while it is out.
- 5
Check the water supply line
If you have an ice maker or water dispenser, inspect the water supply line at the back of the fridge. Look for drips at the connection points. Tighten any loose fittings. A leaking supply line is a common and often overlooked cause.
If That Didn't Work
- Cracked water filter housing
- Ice maker overflow from stuck fill valve
- Condensation from a faulty door seal
When to Call a Professional
If the defrost drain keeps re-freezing within days, the defrost heater or thermostat may be failing. A technician can diagnose and fix the defrost system for $150–$250.
