Owners of modern household appliances are often faced with a situation where water suddenly appears under the vegetable drawers or on the shelves of the refrigerator. For models Atlant with the system No Frost this phenomenon is not the norm, unlike drip defrosting, where moisture flows down the back wall. The appearance of a puddle inside the chamber or under the unit indicates a violation of air circulation or problems with condensate drainage. Ignoring this problem can lead to spoilage of products, the appearance of an unpleasant odor and even failure of electronic control modules.
System No Frost ("without frost") assumes that moisture from the products is frozen on an evaporator hidden behind a plastic panel, and then removed during an automatic defrost. If you notice water, then this well-oiled mechanism has failed. In most cases, the reason lies in a simple blockage of the drainage channel or malfunction of the heating elements. The critical factor is the time of appearance of water: if the puddle forms cyclically, every few hours, the problem is almost certainly related to the defrost cycle. In other cases, the culprits may be mechanical damage or improper operation.
Before calling a technician or disassembling the unit, it is necessary to carry out initial diagnostics. Often, users mistake the consequences of installing too hot products or a door that is not tightly closed as a breakdown. However, if you are sure that the operating mode has not been violated, you should prepare for a deeper intervention. Next, we will analyze in detail the main components that require testing, and action algorithms for restoring normal operation of your Atlanta.
⚠️ Attention: Before starting any work on diagnosing the internal components of the refrigerator, be sure to disconnect the device from the power supply. Working with electrical wiring and moisture without turning off the power is life-threatening.
Clogged condensate drainage system
The most common reason why a refrigerator leaks Atlant with the system No Frostlies in a clogged drainage hole. During operation, moisture deposited on the evaporator must flow into a special tray above the compressor, from where it safely evaporates. If the path of water is blocked by an ice plug or accumulation of dirt, the slurry begins to overflow the evaporator tray and pours inside the refrigerator compartment, most often onto the bottom shelf or into vegetable drawers.
The formation of an ice plug in the drain tube often occurs due to incorrect operation of the defrost system or too infrequent defrosting when the ice does not have time to completely melt and drain. Also, food particles, crumbs or mold can get into the tube, which over time forms a tight blockage. To check, you need to locate the drainage hole on the back wall of the refrigerator (usually it is hidden under a plastic cover) and try to clean it.
The cleaning procedure requires care. Do not use sharp metal objects that could damage the thin walls of the tube or pierce the heat insulator. The optimal solution is to use a soft rubber bulb with warm water or a special brush. If the water is in the hole and does not go away, then there is a plug, and it needs to be dissolved with hot water or carefully pushed through with a flexible cable.
- 🧊 Ice plug: Formed when there is a malfunction in the defrost cycle, requires defrosting the unit for 10-12 hours.
- 🍞 Food debris: Crumbs and food particles that fall into the drain create a mechanical obstacle to the flow of water.
- 🦠 Mold and slime: Biological formations in the warm and humid environment of the tube narrow the passage.
- ❄️ Hypercooling of the tube: If the tube passes through a low temperature zone without proper insulation, the water in it may freeze.
Malfunctions of the evaporator defrost system
If cleaning the drainage did not help, and water continues to accumulate, the problem may lie deeper - in a malfunction of the system itself No Frost. In refrigerators Atlant three key elements are responsible for removing ice from the evaporator: a heating element (heater), a defrost sensor (thermostat) and a timer (or electronic control module). Failure of any of them leads to the fouling of the evaporator with a “coat” of ice, which blocks the ventilation ducts and drainage.
When the ice layer becomes too thick, during the next defrost cycle it does not have time to completely melt, or melt water does not have time to escape through the drainage due to the volume. As a result, excess moisture enters the chamber. Diagnosis of these components requires disassembling the rear panel of the freezer (where the evaporator is located) and using a multimeter to check the continuity of the circuits.
Most often it fails Defrosting heating element. It consists of a nichrome spiral in a metal tube, which burns out over time. Also a common culprit is the defrost sensor, which stops giving the command to turn on the heating or, conversely, does not turn it off on time. The electronic control module responsible for timing cycles breaks down less often, but this possibility cannot be ruled out, especially if there are power surges in the network.
To replace the heating element or sensor, you will need to remove the back wall of the freezer compartment. A visually serviceable heating element cannot always be distinguished from a burnt-out one, so a “continuity test” with a tester is required. The resistance of a working heater is usually between 200 and 300 ohms. If the device shows a break (infinity), the part must be replaced.
| Component | Function | Failure symptom | Test method |
|---|---|---|---|
| Heating element defrost | Heating the evaporator to melt the ice | Ice build-up, water in the chamber | Running with a multimeter (resistance) |
| Defrost sensor | Temperature control heating | Heating does not turn on or heats constantly | Measuring resistance at different temperatures |
| Timer/Module | Switching modes (cooling/defrosting) | Chaotic operation, absence cycles | Checking the presence of voltage on the contacts |
| Fuse | Protection against overheating of the heating element | The heating element does not work at all | Continuity dial (integrity) |
Displacement or damage to the sealing rubber
Another reason for the appearance of moisture may be a violation of the seal of the chamber. If the refrigerator door Atlant does not fit tightly, warm, moist air from the room constantly enters. The system No Frost attempts to compensate for this heat by working in increased mode, which leads to intensive formation of condensation, which the drainage system may not be able to cope with.
Inspect the rubber seal around the perimeter of the door. There should be no cracks, tears or areas of deformation. Often rubber simply becomes contaminated with grease or food, causing it to lose its elasticity and stickiness. In some cases, the door may warp due to weakening of the hinges, which creates a gap in the upper or lower part of the opening.
You can check the tightness of the seal with a simple test with a sheet of paper. Squeeze the sheet with the door and try to pull it out. If the paper comes out too easily or, conversely, breaks with a strong tug only in certain places, it means that the pressure is uneven. Adjusting the hinges or replacing the seal will solve the problem of excess moisture.
⚠️ Attention: When replacing sealing rubber, it is recommended to heat the new cuff with a hair dryer or soak it in warm water before installation so that it becomes elastic and fits tightly into the groove.
Improper operation and loading products
Often users themselves create conditions for leaks without knowing it. Loading into the refrigerator Atlant hot or warm dishes are a direct path to the formation of large amounts of condensation. The system No Frost is designed to remove a certain volume of moisture, but steam from a pot of soup can instantly exceed these limits, and water will begin to drip from the ceiling of the chamber.
It is also important to consider the location of the products. If containers containing liquids or raw foods are placed close to the back wall, they may block the ventilation openings. Impaired air circulation leads to local hypothermia or, conversely, stagnation of moist air, which provokes dew.
- 🍲 Hot food: The release of steam exceeds the capacity of the drying system.
- 🥤 Open liquids: The evaporation of water from open pans increases humidity.
- 📦 Overload: Too many products disrupt air exchange.
- 🚪 Frequent opening: Leaving the door open for a long time lets in a lot of moist air.
The influence of indoor humidity
If the humidity in the kitchen is very high (for example, it is raining or humidifiers are running), the refrigerator may “sweat” outside and inside. This is a physical phenomenon, not a breakdown.
Mechanical damage and manufacturing defects
Although modern refrigerators Atlant are reliable, mechanical damage to the case or internal elements can lead to leaks. For example, during transportation or careless defrosting (if you decide to use sharp objects to chip ice), you can damage the drainage tray or the water drainage tube itself.
In rare cases, manufacturing defects occur, for example, poor-quality sealing of tubes or defects in the plastic elements of the system No Frost. If the refrigerator is new and leaks immediately after installation, this is a reason to contact the service center under warranty. In this case, self-repair may void your warranty rights.
It is also worth checking the integrity of the plastic chute located above the compressor (in some models it is located inside, in others - at the back). If there is a crack in the plastic, water will flow out, creating a puddle on the floor, which is often mistaken for a leak inside the chamber.
Diagnostic algorithm and procedure
To effectively eliminate a leak in the refrigerator Atlant, proceed sequentially. Do not try to check all nodes randomly - this will take a lot of time. Start with the simplest and most likely causes, gradually moving on to complex ones.
The first step should always be to completely defrost the unit. Even if you think there is no ice inside, microscopic crystals in hard-to-reach drainage areas can get in the way. Leave the refrigerator turned off with the doors open for at least 12 hours (preferably a day). This often solves the problem without intervention in the electrical system.
If, after defrosting and cleaning the drainage, water appears again after 1-2 days of operation, proceed to checking the defrost system. Here you will already need tools and basic electrical skills.

⚠️ Attention: Technical characteristics and location of components may vary slightly depending on the specific model Atlant. Always check the technical documentation of your device before disassembling.
Frequently asked questions (FAQ)
Why does water appear only at night or in the morning?
This is a classic sign of problems with the defrost system. Defrost cycles in refrigerators Atlant are often programmed for overnight or idle periods. If the heating element cannot cope or the drainage is clogged, water overflows the pan during or immediately after the defrost cycle.
Is it possible to use a cable to clean the drainage?
Use a hard metal cable strongly not recommended. You could puncture the thin plastic tube or damage the insulation layer, leading to costly repairs. It is better to use a soft brush or a syringe with hot water.
How much does it cost to replace a heating element in an Atlant refrigerator?
The cost consists of the price of the spare part and the work of the technician. The heating element itself is inexpensive, but replacing it often requires complete disassembly of the freezer, which is a labor-intensive process. It is better to check the exact price at service centers in your region.
Does the installation level of the refrigerator affect the appearance of water?
Yes, it does. If the refrigerator is skewed backwards, water from the drain pan may not drain by gravity, but overflow into the chamber. Make sure that the legs of the refrigerator are adjusted so that the door closes on its own if it is released halfway.
What should you do if, after defrosting, water appears again after an hour?
If water appears so quickly, this may not indicate the system No Frostbut a leak outside (for example, condensation on the body due to high humidity) or a serious blockage that could not be broken through. Also check if water is dripping from the ceiling or pipes above the refrigerator.
