Leaking Refrigerator

Clogged or Frozen Defrost Drain

The first component to check in your LG refrigerator is the defrost drain. When it freezes up or gets clogged up with loose debris, it will not function correctly, and the overflowing water will leak out onto the floor.

Clogged or Frozen Defrost Drain

The first component to check in your LG refrigerator is the defrost drain. When it freezes up or gets clogged up with loose debris, it will not function correctly, and the overflowing water will leak out onto the floor.

To check if the defrost drain is the problem, you need to:

Remove any food inside your refrigerator so you can access the drain at the bottom of your refrigerator.

Check the drain to determine if it is clogged up or frozen. You can do this by trying to run some water down it.

If it is frozen, turn the fridge off at the wall and let it thaw out.

If it's not frozen, check for any blockages. If there are no blockages, move on to the next component to check.

Once thawed out, flush the drain out with hot water and then plug your fridge back in.

Turn your fridge back on at the wall, and then observe over the next 24 hours if the problem is solved.

Faulty Water Inlet Valve

The second possible cause of the leak is a faulty water inlet valve. The inlet valve operates by opening up to supply water to the ice maker when required. If it gets a crack in it, then it will become faulty and will cause a leak to occur.

You can check it by:

Turning your refrigerator off and pulling the plug out.

Pull your refrigerator out from the wall so you can access the back of it.

Remove the lower panel at the back of the refrigerator and locate the valve.

Check the valve to see if there are any cracks in it and if it is properly connected to the water supply pipe.

If there are no cracks and it is secured tightly to the water supply line, it is fine and not the cause of the problem. However, if you do find cracks in the valve, it will need to be replaced.

After replacing the valve, put the back panel back on, put the fridge back in its place, and turn the refrigerator back on at the wall.

Damaged Water Tank Assembly

The third component to check is the water tank assembly.

You can inspect the tank assembly by:

Turning the refrigerator off at the wall.

Check your manual for the exact location of the water tank.

Locate the tank and then check it for any signs of leaks coming out of it.

If you find a leak, it will need to be replaced. If you don't find a leak, then the tank is OK.

Once the tank has been replaced, you can turn your refrigerator back on at the wall.

Faulty Water Filter Head

The next component to check is the water filter head. When it gets damaged, the filter won't operate correctly and will cause a leak.

To check the water filter head, you need to:

Locate the water filter head.

Examine the water filter head and the seals for any signs of wear and tear. The most common issue is cracking developing in the water filter head.

If you find any damage, it will need to be completely replaced. If there is no damage, move on to the next possible cause.

Worn-Out Water Filter

The next component to check for damage is the water filter. Sometimes water filters will get worn out and will stop working correctly, which can cause leaks to occur. Keep in mind that you should be replacing your water filter regularly anyway.

To inspect the water filter, you need to:

Turn your refrigerator off at the wall.

Locate the water filter in your refrigerator, and remove it from the water filter housing.

Put it back in the housing and make sure that it fits properly.

If it doesn't fit correctly, this means it has to be replaced.

Once you've replaced the filter, turn the refrigerator power back on. Over 24 hours or so, you should be able to determine if this has solved the problem.

Cracked Drain Pan

The final cause to check is a faulty drain pan. Self-defrosting refrigerators have a drain pan at the bottom of the fridge that collects melted water, which evaporates over time by the condenser fan blowing warm air over the pan. If the drain pan gets a crack in it, this will cause a leak to develop.

To check the drain pan you need to:

Turn your refrigerator off at the wall, pull it out, and then remove the back panel.

Find the drain pan and inspect it for any signs of cracks in it.

If it is cracked, then it will need to be replaced.

Once replaced, you can put the back panel back onto the fridge and put the fridge back into its place.

Turn your refrigerator back on and check if replacing the drain pan has fixed the problem.
