Have you opened the refrigerator LGand there is a puddle underneath it? Or is water dripping from under the door and condensation accumulating on the shelves? A leak does not always mean a serious breakdown: in 70% of cases, the problem is solved on its own in 10–30 minutes. But you cannot ignore it: water under the appliances threatens not only damage to the floor covering, but also a short circuit.
In this article - full analysis of the reasonswhy the refrigerator leaks LG (including models with a system No Frost, Total No Frost and drip defrosting). We will explain in detail how to diagnose the problem, what you can fix yourself, and when you need to urgently call a specialist. You will also find step-by-step instructions, diagrams and a table with typical “symptoms” of malfunctions.
Spoiler: if water accumulates only under the vegetable drawers or flows from under the freezer - This is almost always a clogged drain hole. But when a puddle forms in front under the doorthe seal or incorrect installation is to blame.
1. Clogged drainage hole is the No. 1 reason for leaks in 80% of cases. All refrigerators have a drainage system, even those with one. Its task is to remove condensate that forms during defrosting or operation of the compressor. If the hole becomes clogged with crumbs, food particles or mold, the water does not go into the reservoir, but accumulates inside the chamber or flows onto the floor.
There is a drainage system in all refrigerators LG, even with No Frost. Its task is to remove condensate that forms during defrosting or operation of the compressor. If the hole becomes clogged with crumbs, food particles or mold, the water does not go into the reservoir, but accumulates inside the chamber or flows onto the floor.
How to check: Open the refrigerator and inspect the back wall. At the bottom (usually under the evaporator) you will see a small hole - this is drainage. If water or ice has accumulated next to it, and there is a puddle under the vegetable drawers, the blockage is confirmed.
- 🔍 Signs: water under the lower shelves, ice around the drainage hole, unpleasant smell from the refrigerator.
- 🛠 How to clean: use a special brush (included with some models LG) or a cocktail straw. Rinse the system with warm water and soda (1 tablespoon per 1 liter).
- ⚠️ What not to do: Do not clean the hole with sharp objects (knitting needles, knife) - you risk damaging the tube.

Prevention: rinse the drainage hole every 2-3 months. If you often store open liquids (soups, sauces) in the refrigerator, do this more often. For models with No Frost cleaning the drainage is especially important - the system automatically defrosts the ice, and if the water does not drain, it freezes again, forming ice.
What to do if the drainage tube is frozen?
If the water does not drain even After cleaning, check the tube for icing. To do this:
1. Turn off the refrigerator for 12–24 hours (let the ice melt).
2. After defrosting, clean the tube again.
3. Pour 50–100 ml of warm water into the hole - if it flows out freely, the problem is solved.
If ice forms again, there may be a malfunction of the thermostat or defrost heating element (read section 5).
2. Incorrect installation: why is it flowing from the front under the door
If water accumulates in front of the refrigeratorand not inside the chamber, the problem lies in tilting the case. According to technical standards, the refrigerator LG should stand with a slight slope back (1-2°) so that the door closes tightly. If the equipment is installed crookedly or skewed, the seal does not fit tightly, and warm air penetrates inside.
As a result, the compressor works more intensely, more condensation forms, and water flows down the front wall. This happens especially often in models with French Door (two-door), where precise adjustment of the hinges is important.
- 📏 How to check: take a building level and place it on the roof of the refrigerator. If the bubble is shifted forward, you need to adjust the legs.
- 🔧 How to fix: tighten the front legs (clockwise - higher, counterclockwise - lower). The door should close on its own if it is opened 45°.
- 🚪 Checking the seal: close the door and pull the sheet of paper sandwiched between the seal and the body. If the sheet is easily pulled out, the rubber band needs to be replaced.

Important! After moving the refrigerator LG to a new place, always check its position. Even a slight misalignment can cause a leak within 1-2 weeks. If the floor is uneven, use anti-vibration pads.
⚠️ Attention: If the refrigerator is on a carpeted floor, check to see if the lint is blocking the ventilation holes from below. This can cause overheating of the compressor and increased formation of condensation.
3. The door seal is damaged or worn out
The rubber seal (aka “rubber band”) loses its elasticity over time, cracks or deforms. As a result, warm air enters the chamber, and moisture condenses on the walls and flows down. Characteristic sign —water accumulates along the edges of the door or flows along the front panel.
How to check the tightness:
1. Close the door and shine a flashlight along the seal. If light is visible, there are gaps.
2. Inspect the rubber band for cracks, tears, or signs of mold.
3. Check to see if the seal is coming away from the body (sometimes it simply “comes off” over time).
| Symptom of malfunction | What to do |
|---|---|
| The seal is cracked or torn | Replacement required (buy an original elastic band for the model LG) |
| The elastic band is moving away from the body | Try to glue it with a Moment crystal or replace it |
| The seal is deformed (flattened) | Try to restore the shape with a hairdryer (heat to 60–70°C and shape) |
| There is mold or dirt on the elastic band | Wash with soapy water, dry, treat with silicone grease |
Advice: if the seal is in order, but the door does not close tightly, check the hinges B. models LG with a system Door-in-Door (for example, LG GC-B247SLUV) the internal fasteners often become loose. They can be tightened with a screwdriver.
4. No Frost system malfunction: when it leaks from the freezer
Refrigerators LG s No Frost (for example, series GA, GB, GC) are defrosted automatically thanks to the fan and defrosting heating element. If the system fails, ice builds up on the evaporator, and when defrosting, the water does not have time to go into the drain and flows into the freezer compartment or onto the floor.
Causes of failure No Frost:
- ❄️ The defrosting heating element is broken —does not heat, the ice does not melt, the drainage freezes.
- 🌀 The fan does not work —the cold is distributed unevenly, ice forms.
- 🔌 Problems with the defrost sensor —system “does not understand” when to turn on defrosting.
- 🧊 Clogged freezer drain —water does not drain, accumulates and freezes.
How to diagnose:
1. Turn off the refrigerator, defrost it for 12–24 hours.
2. After turning it on, check whether ice appears on the back wall of the freezer within 24 hours.
3. If the ice builds up again, the problem is No Frost.
⚠️ Attention: if ice appears in the freezer LG With No Frost and the refrigerator begins to work loudly - Do not break off the ice with a knife or other sharp objects! This may damage the evaporator and lead to a leak of freon.
Repairing the system No Frost usually requires replacing the heating element, sensor or fan. This not done by hand requires special tools and knowledge of the refrigerator circuit. Average cost of repairs at a service center: 3,000–8,000 ₽ (depending on the model).
5. The condensate tank or tube is broken
At the bottom of the refrigerator LG (usually above the compressor) there is a plastic reservoir into which water flows from the drainage. If it cracks or moves out of place, liquid will spill onto the floor. Also, the problem may be in connecting tube between the drainage and the reservoir - it sometimes rubs or falls off.
How to check:
1. Carefully move the refrigerator and inspect the bottom.
2. The reservoir is usually white or transparent, located next to the compressor.
3. If there are cracks on it or it is wet, the reason has been found.
Solution:
- If the tank is cracked, replace it (costs 500–1,500 rubles).
- If the tube has come off, put it back on and fix it a clamp.
- If the tube is frayed, replace it with a new one (you can use a silicone hose of a suitable diameter).
In some models LG (for example, LG GA-B489YGQZ) the reservoir is hidden under the panel - to access it you will need to remove the bottom cover. If you are not confident in your abilities, it is better to call a specialist.
6. Freezing of food and other “household” reasons
Sometimes the refrigerator LG leaks not because of a breakdown, but because of improper operation. Here 4 common mistakesthat lead to leaks:
- 🥦 Storing hot food - steam condenses on the walls and flows down. Always cool food to room temperature before storing.
- 🚰 Defrosting food in the refrigerator —melt water overflows the drainage. Use special containers.
- 🧊 Excessive loading of the freezer blocks air circulation, the ice melts unevenly. Leave 2–3 cm between the food and the walls.
- 🔥 Opening the door frequently in hot weather —the compressor wears out, excess condensation forms. Try to open the refrigerator less often.
How to avoid:
- Defrost the refrigerator regularly (even with No Frost - once every 6-12 months).
- Do not place open containers with liquid (soups, milk, sauces) into the chamber.
- Check that the door is closed tightly - sometimes protruding products block it.
If a leak appeared after moving or transportation, the internal tubes may have been damaged. In this case, the refrigerator must be taken to a service center for diagnostics.
7. Failure of the thermostat or compressor: when it leaks + does not freeze
If the refrigerator LG not only leaks, but also does not freeze well, the reason may be:
- 🌡️ Faulty thermostat — “deceives” the system, forcing the compressor to work without stopping. As a result, too much condensate is formed.
- ⚙️ Wear of the compressor —cannot cope with the load, the temperature in the chamber jumps, ice melts uncontrollably.
- 🔋 Freon leak —the refrigerator stops cooling, ice forms melts, the water flows like a stream.
Signs of a serious breakdown:
- The refrigerator works without stopping or, conversely, rarely turns on.
- The freezer is warmer than it should be (for example, -8°C instead of -18°C).
- a thick layer of ice forms on the back wall of the refrigerator compartment.
⚠️ Attention: if you suspect a freon leak, do not turn on the refrigerator after defrosting! Freon is toxic, and without it the compressor runs “idle” and may burn out, call a technician immediately.
Repair cost:
- Replacement of the thermostat: 2,000–4,000 ₽.
- Compressor repair: 5,000–12,000 ₽.
- Freon refilling: 3,500–7,000 ₽ (depending on the model).
8. When to call a specialist: 5 signs of a serious problem. breakdown
Not all leaks can be repaired on your own. Urgently contact the service center LGif:
- The refrigerator leaks continuouslyand the puddle appears again a few hours after cleaning.
- Water has unpleasant odor or strange color (may indicate mold in the drain or oil leak from the compressor).
- Refrigerator does not cool, but the light inside is on.
- Audible unusual sounds: loud buzzing, clicking or crackling noise (there may be problems with the compressor or fan).
- The display lights up error code (for example,
Er IF,Er FF- indicate problems with defrosting).
How choose a service:
- Official centers LG give a guarantee for repairs (1-2 years).
- Check reviews of the workshop - especially pay attention to complaints about repeated breakdowns.
- Check whether they use original spare parts (in cheap services may install low-quality analogues).
The average cost of diagnostics in Moscow and St. Petersburg: 1,500–2,500 rubles. If the refrigerator is under warranty, the repair will be free (but the warranty does not cover breakdowns due to improper use!).
FAQ: Frequently asked questions about leaks in LG refrigerators
❓ Why does an LG refrigerator with No Frost leak if the drainage is clean?
In models with No Frost leakage with clean drainage is usually associated with a malfunction of the defrosting system: the heating element, sensor or timer is broken. Also check the fan - if it does not work, ice builds up on the evaporator, and when defrosting, the water does not have time to go into the drainage. Diagnostics requires disassembling the freezer, so it is better to call a specialist.
❓ Is it possible to use an LG refrigerator if. it flows, but freezes normally?
It is possible for a short time (1-2 days), but it is risky: water can damage the flooring or seep into electrical components. If the reason is a clogged drain or a skewed door, fix it immediately. If it is leaking due to a breakdown (heating element, compressor), turn off the refrigerator and call a technician. data-i="254">❓ How much does it cost to repair a leak in an LG refrigerator?
❓ How much does it cost to repair a leak in an LG refrigerator?
The cost depends on the reason:
- Cleaning the drainage: 1,000–2,000 ₽ (if you call a specialist).
- Replacement of the seal: 2 500–4,000 ₽.
- Repair of the No Frost system: 3,000–8,000 ₽.
- Replacement of the water tank: 1,500–3,000 ₽.
In official services LG prices are higher, but they provide a guarantee of up to 2 years.
❓ Why does the LG refrigerator leak even more after defrosting?
It is normal if the water goes away within 1-2 hours. But if the puddle does not disappear, the following are possible:
- Clogged drainage tube (after). during defrosting, ice particles could get into it).
- Damage to the condensate tank (during defrosting, the plastic could crack).
- Malfunction of the defrosting heating element (ice melts unevenly, drainage does not cope).
Wipe the refrigerator dry and observe for 12 hours. If the leak does not stop, look deeper for the cause.
❓ How often should you clean the drainage in an LG refrigerator?
Recommended frequency:
- For models with a drip system: once every 3 months.
- For No Frost: once every 6 months.
- If open liquids (soups, milk) are often stored in the refrigerator: once every 1-2 months.
Use warm water with soda or special products for cleaning refrigerators (for example, Topperr 3104).
