The situation when the refrigerator is runningalways takes you by surprise and causes panic. A puddle in the kitchen may appear suddenly, and the first thing you need to do is determine where exactly the water is coming from: from inside the chamber, from under the door or from behind the unit. Water on the floor is not just a damaged laminate, it is a signal that the moisture removal or refrigerant circulation system has failed.
Most often the cause is trivial clogged drain holewhich can be easily fixed on your own in a couple of minutes. However, in some cases, the problem lies in more serious malfunctions, such as malfunction of the evaporator heating element or a violation of the system's tightness. Understanding exactly how moisture moves inside your Indesit or LGwill help you quickly localize the source of the problem and avoid an expensive call to the technician.
In this In this article, we will analyze in detail all possible scenarios why equipment begins to leak, and provide a step-by-step algorithm of actions. It is important not to ignore the first drops of water, as prolonged exposure of electrical components to moisture can lead to a short circuit. In 80% of cases, a leak inside the refrigerator compartment is caused by the freezing and subsequent thawing of ice in the drainage channel.
Anatomy of a leak: where exactly does the water flow?
Before grab the tools, it is necessary to carry out an initial diagnosis. The location of the water is a key factor in determining the cause. If water accumulates on the floor under the refrigerator, this may be due to an overflow evaporation tray on the compressor or a leak in the drain hose. In this case, the moisture flows by gravity down the back wall of the case.
It’s a completely different matter when the refrigerator is leaking inside. Water collects on the bottom shelf of the refrigerator or under the vegetable drawers. This is a classic sign that the condensate that forms on the rear wall during operation of the compressor does not go into the drain, but overflows over the edge of the groove. Also, water may appear between the door and the body, which indicates problems with sealing rubber.
Sometimes users notice water in the freezer compartment, where it should not be. If you have a No Frostsystem, the presence of puddles or ice at the bottom of the freezer indicates that the water from defrosting does not have time to evaporate or goes into the drainage. In models with a drip defrosting system, water in the freezer is almost always a sign of a loose door seal.
- 🔍 Puddle under the refrigerator: Check the integrity of the outlet hose and the level of the evaporation tank.
- 💧 Water on the floor of the refrigerator compartment: Drainage is clogged or the evaporator is frozen.
- ❄️ Moisture in the freezer: Loose door seal or failure of defrost cycles.
Clogged drainage hole: the most common cause
If you notice that the refrigerator is leaking inside under vegetable boxes, in 9 out of 10 cases the drainage hole is to blame. It is located at the bottom of the rear wall of the refrigerator compartment. Its function is to remove condensate that flows along the corrugated surface of the evaporator. Over time, dust, food crumbs and mold accumulate in this hole, forming a plug.
When the channel is clogged, the water has nowhere to go, and it begins to overflow over the edges of the receiving groove, spreading across the shelves. You don't need to be an engineer to fix this problem. You will need a soft wire (for example, from a charger phone) or a special brush, as well as a rubber bulb or syringe.
First, carefully clean the hole, being careful not to damage the inner walls of the plastic. Then fill a bulb or syringe with warm (not boiling water!) water and rinse the canal under pressure. If the water flows freely into the tray above the compressor at the back, the problem is solved. In some models, for example Atlant or Beko, the drainage may have a removable pipe that can be removed and washed under the tap.
☑️ Cleaning the drainage
⚠️ Attention: Never use sharp metal objects (knitting needles, knives) to clean the drain unless absolutely necessary. You can pierce the thin channel wall or damage the evaporator, which will lead to freon leakage and expensive repairs.
Problems with the No Frost system and defrost heating element
Owners of modern models with the system No Frost also encounter leaks, but their nature is different. Here, water is formed during the automatic defrosting of the evaporator hidden behind the rear panel. If defrost heating element the sensor (defroster) burns out or fails, the ice on the evaporator does not melt, but grows.
Sooner or later, the “coat” of ice becomes so large that melt water (from rare switching on of the heating element or simply from the heat of the food) begins to drip into the chamber or leak out through the vents. Also, water may leak if the drainage tube leading from the hidden evaporator to the tray is clogged.
Diagnosis of such a malfunction requires partial disassembly of the refrigerator. It is necessary to remove the back panel in the freezer and inspect the evaporator. If it is covered in ice, and the heating element is cold and does not heat when voltage is applied, the heating element needs to be replaced. This is a more complex repair that requires a multimeter and electrical skills.
How to check a defrosting heating element with a multimeter?
To check the heating element, you need to remove the terminals from it and ring the resistance. The normal resistance of a working heating element is from 200 to 500 Ohms. If the device shows infinity (open) or zero (short circuit), the heating element must be replaced. Before checking, be sure to disconnect the refrigerator from the power supply!
Faulty seals and skewed doors
Sometimes the answer to the question why the refrigerator is runninglies not in the water drainage system, but in a violation of the tightness of the circuit. If the door does not fit tightly, warm, humid air from the kitchen constantly enters. This leads to increased formation of condensation on the walls, which the drainage simply cannot cope with.
In addition, warm air causes abundant freezing of ice on the back wall. When the compressor turns off, this ice melts, forming huge puddles. Check sealing rubber along the perimeter of the door. It should be clean, elastic and free of cracks. Dirt and grease reduce the stickiness of the rubber.
Also check whether the refrigerator is level. If it is tilted forward, the door may not close completely on its own. Ideally, the refrigerator should be tilted slightly backwards so that the door closes under its own weight. Adjust the height of the front supports using a building level.
| Symptom | Possible cause | Solution method |
|---|---|---|
| Door does not magnetize | Contamination seal | Wash with soapy water |
| Gap in the corner of the door | Distortion of the body or hinge | Adjusting the supports or hinges |
| Rubber cracked | Wear of material | Replacing the seal |
| Ice at the door joint | Constant air flow | Tightness check |
Mechanical damage and wear of hoses
Mechanical factors should not be discounted. If your Samsung or LG has been standing for many years, the plastic elements could simply dry out and crack. This is especially true for drainage baths and connecting pipes. Plastic becomes brittle due to temperature changes and vibration of the compressor.
Another hidden problem is the displacement of the refrigerator. If you moved the unit, the water drainage hose from the compressor may have come off or the tray may have been damaged. In this case, water will drip directly onto the floor, bypassing the internal chambers. Inspect the back of the refrigerator in good lighting.
Sometimes leaks are caused by improper use. For example, placing hot pots in the chamber. The steam instantly condenses and turns into water, the volume of which exceeds the design capacity of the drainage system. Also, do not tightly pack the shelves with products close to the back wall - this interferes with air circulation.
When it’s time to call a technician
There are situations when self-repair can be not only useless, but also dangerous. If after cleaning the drainage and checking the seal the refrigerator continues to leak, the problem may be deeper. For example, a violation of the thermal insulation of the housing or a hidden leak of freon, leading to incorrect operating cycles.
Also, the help of a specialist is necessary if the heating element, defrost timer or control module needs to be replaced. This work involves disassembling the case, electrical measurements and knowledge of the circuitry of specific models, such as Bosch or Whirlpool.
Pay attention to the smell. If you smell burnt wiring or plastic along with the water, immediately unplug the appliance. Water may have gotten onto the electrical contacts, causing a short circuit. The operation of such a device is prohibited.
⚠️ Attention: If you find that water is leaking from inside the refrigerator body (between the outer wall and the inner chamber), this may indicate depressurization of the sealed circuit. It is impossible to eliminate this on your own - factory repairs or replacement of thermal insulation are required.
Prevention of leaks and care of equipment
To prevent the question “why is the refrigerator running” from bothering you in the future, it is enough to follow simple operating rules. Regularly, at least once every six months, check the cleanliness of the drainage hole. Preventative washing takes 5 minutes, but saves you from large puddles.
Keep the rubber seals clean. Wipe them with a damp cloth and mild detergent, removing any grease or sticky residue. This will extend the life of the rubber and ensure a tight seal on the door. Do not allow a thick crust of ice to form in the freezer.
It is also important to place food correctly. Do not place containers with liquid close to the back wall. Ensure free air circulation inside the chambers. If you notice that the refrigerator begins to work longer than usual or turns on more often, this is a reason for diagnosis, since excessive condensation formation is often associated with overheating or an incorrect operating cycle.
Why does the refrigerator leak after defrosting?
If after complete defrosting and washing the refrigerator is leaking, most likely you did not completely dry the drainage hole or assembled the unit incorrectly. It is also possible that there was a piece of ice left in the drain tube, which melted later and started leaking. Let the refrigerator stand turned off for a few more hours.
Is it possible to operate the refrigerator if it is leaking?
For a short time - it is possible if you have time to remove the water. But long-term use is dangerous: water can get on electrical parts, cause metal corrosion and mold, which is harmful to health. In addition, constant moisture spoils the floor covering.
What to do if the water has a strange color or smell?
If the water in the pan or inside the chamber has a rusty tint or an unpleasant odor, this indicates stagnation of water in the drainage system and the growth of bacteria. It is necessary to thoroughly disinfect the drainage with a soda solution or a special product for cleaning refrigerators.
Does the installation level affect leaks?
Yes, directly. If the refrigerator is tilted forward, the door will not close tightly on its own, and condensation may not drain properly into the drain. The correct tilt is strictly vertical or with a minimal slope back.
