When operating refrigeration equipment, owners often notice that moisture periodically appears on the shelves or under the unit, although there are no obvious leaks from the outside. For many users, the physical principle of operation of the condensate removal system remains a mystery, especially in models with drip defrosting, which are the most popular in the line of the Belarusian manufacturer.
Moisture formed on the back wall of the chamber flows down under the influence of gravity and falls into a special trench, from where it goes through a narrow channel into the external evaporation pan. There it naturally evaporates thanks to the heat generated by the operating compressor, which makes the process completely autonomous and does not require human intervention.
However, if the system becomes clogged or the tightness of the connections is broken, water can overflow over the edge of the gutter or drip inside the chamber, creating puddles on the kitchen floor. Understanding where exactly the liquid goesis the first step to diagnosing malfunctions and preventing damage to the floor covering.
The principle of operation of the drip defrosting system
In refrigerators Atlant with manual or semi-automatic defrosting, the moisture removal process is based on the physics of condensation. Warm air entering the chamber when the door is opened, or moisture from the products settles on the coldest surface - the rear evaporator, turning into frost.
When the compressor turns off, the evaporator temperature rises, and the frozen ice melts, turning into water. This water flows down the ribbed surface of the back wall, ending up in a collection tray. From there, through the drainage hole, it is directed into a tube leading to the pan above the engine compartment.
⚠️ Attention: In models with the system No Frost the principle is different - the water evaporates inside the chamber during the operation of the fans, and visible flow down the rear wall during the defrost cycle should not be observed.
The key element here is the drainage hole, the diameter of which is selected so as to allow a sufficient amount of water to pass through, but not to release cold air from the chamber to the outside. It is in this node that problems most often arise that require user intervention.
Condensate path: from chamber to pan
The route that water takes is quite short, but requires ideal passability in all areas. The moisture first collects in a channel at the base of the back panel. Then it flows by gravity into the drainage tube, which passes through the insulation of the refrigerator body.
The design of the tube in Atlantakh is often made of flexible plastic, which can be deformed under mechanical stress or temperature changes. The outlet of the tube is located directly above the pan mounted on the compressor.
The heat from the running engine heats the pan, providing intense evaporation of moisture. During normal operation, the water in the pan should not stagnate; it manages to evaporate faster than it accumulates.
Typical causes of clogged drainage channel
The main reason that water stops flowing into designated place and begins to leak out or accumulate at the bottom of the refrigerator, this is a banal blockage. Debris, food particles and mold are the main enemies of the drainage system.
- 🍞 Food residues: Bread crumbs, pieces of vegetables or fruits can accidentally fall into the gutter and get stuck in the narrowest place of the tube.
- 🦠 Mold deposits: The moist and dark environment inside the drainage is ideal for the development of bacteria that form a slippery biofilm that narrows the passage.
- ❄️ Ice plug: If the refrigerator operates in a mode in which the water in the tube does not have time to drain and freezes, an ice jam forms, completely blocking the outflow.
To clean the canal at home, soft wire or a special brush is often used. It is important to act carefully so as not to pierce the thin walls of the plastic tube, which is located inside the case.

Comparison of moisture removal systems in different models
Different series of refrigerators Atlant may have design features in the organization drain. This affects the frequency of maintenance and the likelihood of leaks.
| System type | Drain location | Cleaning frequency | Risk of leakage |
|---|---|---|---|
| Drip (Static) | External pan above the compressor | Once every 6-12 months | Medium (clogs) |
| No Frost | Internal evaporator (behind the panel) | Rarely (in case of malfunction) | Low (except for heating element failure) |
| Hybrid | Combined tap | Once a year | Average |
In models with a drip system, the user can visually control the process, while in No Frost the entire system is hidden behind plastic panels, and problems with water drainage can only be identified by puddles under the refrigerator or icing in the freezer.
Mechanical damage and displacement elements
Dirt is not always the cause of problems. Mechanical factors play an equally important role, especially if the refrigerator has recently been transported or moved. The drainage tray may become dislodged or cracked.
Often a situation occurs when the outlet tube simply jumps off the mount or moves to the side, and water flows past the tray directly onto the floor or onto electrical components. It is also possible that the gutter itself on the back wall inside the chamber may be damaged due to inaccurate defrosting with a sharp object.
If you notice that water is dripping not from the hole, but, for example, from under the door seal, this may indicate that the housing is skewed. Incorrect installation of the refrigerator leads to the fact that water does not enter the drain funnel, but overflows over the edge of the gutter.
⚠️ Attention: If cracks are detected in the plastic elements of the drainage system, the use of sealants is permissible only on the outside and only with food compositions that are safe in contact with products.
The influence of temperature and mode work
The intensity of condensation formation directly depends on how often you open the door and what temperature is set inside. The greater the temperature difference, the more moisture settles on the walls.
If the room where it is Atlantis high humidity or hot, the drainage system may not be able to cope with the volume of incoming liquid. The water simply does not have time to evaporate from the pan and overflows.
In addition, if the refrigerator is too close to the wall, air circulation around the engine compartment is disrupted. The pan does not warm up to the required temperature, and the evaporation process slows down, which leads to overfilling of the container.
Why can the water in the pan freeze?
If the refrigerator is in an unheated room (for example, on a balcony or in a garage) at subzero temperatures, the water in the pan can freeze, forming an ice block that blocks further flow.
Maintenance and prevention rules
In order for the water drainage system to work like a clock, it is enough to follow simple operating rules. Regular defrosting (even in No Frost systems, preventative defrosting once a year is recommended) helps maintain hygiene.
It is necessary to ensure the cleanliness of food by packing it in containers or bags. This will prevent crumbs and debris from getting into the gutter. It is also important to check the horizontal installation of the refrigerator using a building level.
To clean the drainage hole, you can use warm water, pouring it into the channel, or a soft nylon brush. Chemicals should be used with caution, thoroughly washing off their residues.
Why does water flow out from under the refrigerator door?
Most often this is due to the fact that the drainage hole clogged, and the water has nowhere to go except over the edge of the inner gutter. The second reason is the skew of the body, due to which the water does not flow into the drain, but forward.
Is it possible to use boiling water to defrost the drainage?
It is not recommended to use boiling water, since a sharp temperature change can damage the plastic of the tube or cause a burn. It is better to use warm water (about 50-60 degrees) or a special defrost.
How often should you clean the Atlant drainage system?
Preventive cleaning is recommended every 6 months or every time the refrigerator is completely defrosted. If you notice a slowdown in drainage, cleaning must be done immediately.
What to do if the drainage tube bursts inside the housing?
If the damage is inside the insulation, independent repair is difficult. Partial disassembly of the rear wall or the use of special repair compounds that are injected through the channel will be required. In difficult cases, it is better to contact the service.
