The refrigerator is working, but water is flowing: reasons and what to do

You opened the refrigerator, and there was a puddle under it. Or worse: water drips right from under the door onto the floor, although the motor is humming, the light is on, and the food seems to be cooling. Is the situation familiar? Leaking in working refrigerator is one of the most common malfunctions faced by owners of equipment of any brand: from budget Indesit and Atlant to premium Liebherr and Samsung.

The reasons can be either trivial (it is enough to clean the drain hole) or serious (the evaporator or thermostat needs to be replaced). In this article, we will analyze all possible sources of leakage, learn how to diagnose the problem by indirect signs and give step-by-step instructions on how to fix the leak yourself - or when it’s time to call a specialist.

Spoiler: in 80% of cases, a clogged drainage system or improper installation of the refrigerator is to blame. But there are also more insidious breakdowns that lead not only to puddles, but also to damage to equipment.

1. A clogged drain tube is the most common cause of a leak.

If a refrigerator with a system No Frost or drip defrosting starts to "cry", first check drainage tube. It is responsible for removing condensate that forms during compressor operation. Over time, crumbs, food particles, mold get into the tube - and the water stops going into a special pan.

How to understand that a blockage is to blame?

• 💧 Water accumulates under the vegetable boxes (in models with drip system) or flows down the back wall.
• 🧊 A thick layer of ice is formed in the freezer compartment a thick layer of ice on the bottom or back wall.
• 🚿 When When you open the refrigerator door, you hear the sound of gurgling water.

You can clean the drainage yourself. You will need:

• 🧻 A cotton swab or thin wire (for example, from a hanger).
• 💦 Warm water with soap or soda solution (1 tablespoon per 1 liter of water).
• 🧴 A syringe or rubber bulb (for flushing).

Unplug the refrigerator and remove all food

Find the drainage hole (usually at the bottom of the back wall of the refrigerator compartment)

Gently push the clog with a wire or stick

Wash the tube with warm water and soap through a syringe

Wipe all surfaces dry and turn on the refrigerator-->

Attention! Do not use sharp objects (knives, knitting needles) - they can damage the plastic tube. If the blockage is deep and cannot be removed, it is better to call a specialist.

2. Incorrect installation of the refrigerator: why it flows from the front

If puddles appear in front of the refrigeratorand not inside, the problem may be in its position. Many people lose sight of the fact that equipment must stand strictly according to the level. When you tilt forward, the door opens slightly, warm air enters, and the compressor begins to work more intensely. As a result:

• 🌡️ More condensation forms on the back wall.
• 💦 The water does not have time to evaporate and flows onto the floor.
• ❄️ Ice builds up in the freezer, which adds moisture when thawed.

How to check and fix:

1. Take a building level and place it on the lid of the refrigerator.
2. If the bubble is shifted forward, adjust front legs (tighten them clockwise).
3. Check that the refrigerator does not wobble - all 4 legs should touch the floor.

Also, a leak in the front can occur due to damaged door seal. If the rubber is torn or has lost its elasticity, warm air penetrates inside and the refrigerator “cries”. Check the seal: hold a sheet of paper between the door and the body. If it falls out, it’s time to change the rubber band.

3. Failure of the No Frost system: when the ice melts at the wrong time

Refrigerators with No Frost (or Frost Free) theoretically should not require defrosting. But if the system fails, ice accumulates on the evaporator, and when defrosting, water flows down - sometimes directly onto the floor.

Signs of a malfunction No Frost system:

• ❄️ Forms in the freezer compartment "fur coat" made of ice (although according to the instructions it should not be).
• 🔊 The refrigerator has become work louder —the fan clings to the ice.
• 🌡️ Temperature in the cells unstable (too cold, sometimes warm).

What could be the matter?

Attention! If in the refrigerator No Frost appeared ice do not chip it with a knife or other sharp objects - you risk damaging the evaporator or freon tubes. Defrost the equipment naturally (unplug it) or use a hairdryer at minimum power.

4. Leak due to a faulty evaporator or thermostat

If the refrigerator leaks continuouslyeven after cleaning the drainage and leveling, the problem may lie in the breakdown of key components:

1. Evaporator (in models with drip system).

If the evaporator is damaged or frozen, the condensate does not evaporate, but flows down. This is often accompanied by:

• 🌡️ Increased temperature in the refrigerator compartment.
• ❄️ Ice crust on the back wall.
• 💧 Permanent puddles under the vegetable drawers.

2. Thermostat (thermostat).

If the thermostat is broken, the compressor works without stopping or, conversely, turns on too rarely. This leads to:

• 🌡️ Freezing rear wall and condensation formation.
• 💦 Leaks due to uncontrolled thawing.
• 🔊 Atypical sounds (compressor not turns off).

How to check the thermostat?

1. Unplug the refrigerator.
2. Remove the protective cover (usually it is located inside the chamber, next to the light bulb).
3. Find The thermostat is a small box with a tube leading to the evaporator.
4. Ring the contacts with a tester. At room temperature they should be closed.

What to do if the thermostat is faulty?

If the thermostat does not ring or shows the wrong resistance, it needs to be replaced. To do this:

1. Buy a similar part (specify the refrigerator model).

2. Disconnect the old thermostat, remembering the connection diagram.

3. Connect the new one and secure it in place.

Important: before replacing, take a photo of the wires so as not to reverse the polarity!

Attention! Working with the thermostat and evaporator requires skill. If you are not confident in your abilities, it is better to call a specialist - errors during repairs can lead to a freon leak or short circuit.

5. Damage to the condensate tank

At the bottom of the refrigerator (usually above the compressor) there is plastic traywhere condensate flows from the drain tube. If it is cracked or displaced, water will drip past - directly onto the floor.

How to diagnose:

• 🔍 Look under the refrigerator (you can use a flashlight).
• 💧 If the tray is skewed or a crack is visible - this is the source of the leak.
• 🔧 Sometimes the pan simply moves when moving the refrigerator.

Solution:

• If the pan is intact, but shifted - put it in place (it should be located strictly under the drainage tube).
• If it is cracked, replace it with a new one (the part can be ordered according to the refrigerator model).
• Temporary option: place it under the tube plastic container (for example, a cut bottle).

Attention! Do not ignore cracks in the pan. Water entering the compressor can cause short circuit or rust on metal parts.

6. Freon leak: when a leak is a symptom of a serious breakdown

If the refrigerator not only leaks, but also poor cooling, the cause may be refrigerant (freon) leak. malfunctions, because:

• 🔧 Requires professional repair (cannot be fixed on your own).
• 💸 The cost of repair can reach 50–70% of the price of a new refrigerator.
• ⚠️ If there is a leak, the freon evaporates and the compressor runs “idle,” which leads to its overheating.

Signs of a freon leak:

• 🌡️ Refrigerator does not maintain temperature (food spoils faster).
• 🕒 The compressor is running without stopping or turns off for a short time.
• 🔊 Appears hissing (the sound of escaping gas).
• 💧 Condensation flows down the back wall, although the drainage is clean.

What to do?

1. Unplug the refrigerator.
2. Do not try to find the leak yourself - freon colorless and odorlessbut is harmful if inhaled.
3. Call a technician. He will:
• 🔍 Find the leak (most often it is soldered pipe connections).
• 🛠️ Eliminate the damage and fill the system with freon.
• 🧪 Check the tightness.

7. Additional reasons: from defects to external factors

Sometimes the refrigerator leaks for reasons not related to breakdowns:

1. Defect or manufacturing defect.

If the refrigerator is new and leaks from the first days, this is possible. manufacturing defect (for example, the drainage tube is installed incorrectly or the pan is damaged). In this case:

• 📄 Check warranty card.
• 📞 Contact the brand service center (for example Bosch, LG or Beko).
• 🚫 Do not try to repair it yourself - this may void the warranty.

2. High humidity in the room.

If the refrigerator is in a damp room (for example, in an unheated cottage or basement), condensation may form outside on the door or side walls. This is not a breakdown, but can lead to rust. Solution:

• 🌬️ Install desiccant next to refrigerator.
• 🔥 Use a heater (if the room is non-residential).
• 🧽 Wipe the case regularly with a dry cloth.

3. Incorrect operation.

Even a working refrigerator can “cry” if:

• 🍲 is placed in it hot dishes (steam condenses on the walls).
• 🚪 Keep the door open for a long time (the temperature balance is disturbed).
• 🧊 Defrost with a knife or fork (can be damaged evaporator).

FAQ: Frequently asked questions about leaks in the refrigerator
