Owners of refrigeration equipment often encounter an incomprehensible phenomenon: after automatic or manual defrosting, water forms under the unit or inside the chamber. For refrigerators Atlant, which have been in demand in the post-Soviet space for decades, this is especially true due to the design features of the drainage system. Understanding where exactly the moisture goes is the key to maintaining a clean kitchen and a long compressor life.
Moisture appears constantly during operation. This could be condensation forming on the walls, or water from melting frost. In modern models with a system No Frost this process is automated, and the user hardly notices it. However, in classic models with a drip system or combined cooling, the water path requires periodic monitoring by the owner.
If you notice a puddle on the floor, do not panic. Most often, the problem lies in a banal blockage or displacement of the container. Let's analyze the liquid drainage device in detail so that you can independently diagnose and fix the malfunction without calling a technician.
The principle of operation of the drip moisture removal system
In classic models Atlant with drip defrosting, the back wall of the refrigerator compartment plays the role of an evaporator. When the compressor is running, a thin layer of ice builds up on it. When the thermostat detects that the desired temperature has been reached, the motor turns off and the wall begins to warm up. The ice melts, turning into water, which flows down the gutter.
This gutter is a special one water collectorlocated at the bottom of the rear panel. This is where all the resulting liquid should drain. The design is made in such a way as to minimize the likelihood of overflowing, however, if there is severe ice fouling or blockage, the efficiency may decrease.
From the water collector, water enters the drainage hole. This is a narrow channel that passes through the thermal insulation of the housing and removes moisture outside into the technical compartment. There is a tray installed where the water gradually evaporates due to the heat from the operating compressor. Thus, in a working refrigerator, water does not spill out onto the floor, but circulates inside a closed circuit.
Location of the drainage hole and the path of water movement
Where exactly is the water outlet point? In refrigerators Atlant the drainage hole is located strictly in the center of the lower part of the rear wall of the refrigerator compartment. It is often closed with a plastic plug or decorative trim that can be easily removed for cleaning. The diameter of the hole is usually about 10-15 millimeters.
The water path runs through a tube, which can be flexible or rigid, depending on the year of manufacture of the model. This tube drains the condensate into a tray mounted above the compressor at the lower rear of the unit. It is important to understand that water does not flow out directly, but accumulates in this tray.
Evaporation in the tray occurs due to the heat generated condenser (black grille at the back) or the compressor itself. If the room is too cold or the air humidity is critically high, the evaporation process may slow down and water will begin to overflow over the edge of the pan directly onto the floor.
| System element | Location | Function |
|---|---|---|
| Gutter | Bottom of the rear wall | Collection of flowing water |
| Drainage | Center of the gutter | Moisture transportation |
| Tube | Inside the body | Connection of chamber and tray |
| Tray | Above the compressor | Moisture evaporation |
Why water flows out: the main reasons
If you find water on the kitchen floor, this is a signal that the drainage system is malfunctioning. The most common reason is clogging a drainage hole. Crumbs from food, mold or mucus can completely block the narrow channel, preventing water from leaving.
The second reason lies in mechanical damage or displacement of the tube. If the refrigerator was frequently moved during cleaning or transportation, the drainage tube could come off the fitting or crack. In this case, the water bypasses the pan and pours directly onto the floor.
The third reason is freezing of the water in the channel. This often happens if the refrigerator is operated in an unheated room at low temperatures. The ice plug blocks the drain, the water overflows the gutter and flows out through the door or under the unit.
⚠️ Attention: If the water has an unpleasant odor or a cloudy color, this is a sign of the development of bacteria in the drainage system. Immediate disinfection of the channel is required.
Instructions for cleaning the drain hole
Removing a blockage is a procedure available to every user. You don't need special tools, just be careful. Before starting work, be sure to disconnect the refrigerator from the power supply for your safety.
First, empty the bottom shelf of the refrigerator compartment. Remove the plastic covers from the water collector, if present. Visually inspect the hole: if debris is visible, remove it with tweezers or a dry cloth. Do not use sharp metal objects to avoid piercing the thin walls of the canal.
For deep cleaning, use soft wire, fishing line or a special brush. Carefully insert the tool into the hole using a rotating motion. After mechanical cleaning, rinse the canal with warm water from a syringe or syringe without a needle. The water should drain freely.

Features of the No Frost system in Atlant models
In models with the system No Frost the principle of water drainage is different. Here, moisture does not accumulate on the walls of the chamber, but settles on a hidden evaporator located behind the rear panel. The heating element is periodically turned on, which melts the ice, and the water flows into the drainage.
The problem in such models is often the freezing of the drainage inside the housing. Since access to it is difficult, water begins to accumulate under the evaporator and eventually flows into the fridge compartment, freezing at the bottom or pouring out through the threshold.
Cleaning systems No Frost often requires partial disassembly of the rear wall. If you do not have the skills to repair household appliances, it is better to entrust this procedure to specialists so as not to damage fragile plastic elements and sensors.
How to defrost a hidden drain?
The safest way is to completely defrost the refrigerator with it turned off for 24 hours. Leave the doors open. The ice in the canal will melt and the water will drain. Do not use a hairdryer to speed up the process inside the chamber - this can damage the plastic.
Preventing the formation of blockages and puddles
To ensure that the water drainage system works smoothly, monitor the temperature conditions. Do not set the refrigerator temperature too low, as this will cause excessive condensation to form. Optimal mode - +4...+5°C.
Regularly check the condition of the door seals. If they do not fit tightly, warm, moist air enters the chamber, which sharply increases the amount of condensation. The drainage system may simply not have time to cope with such a volume of water.
Once every six months, carry out preventative flushing of the drainage hole with a solution of soda or a weak solution of vinegar. This will help prevent the growth of bacteria and the formation of mold, which often causes unpleasant odors and blockages.
⚠️ Attention: Do not store unpackaged food in the refrigerator. Food particles entering the gutter rot and create an ideal environment for blockages.
When it is necessary to call a specialist
There are situations when self-repair can lead to more serious damage. If, after cleaning, water continues to accumulate, the problem may be a malfunction of the thermostat or defrost heating element (in No Frost models). It is difficult to diagnose this without a multimeter and knowledge of electrical engineering.
Also, the help of a specialist is needed if you find a crack in the housing or drain tube, which cannot be reached without disassembling the housing. An attempt to seal such places with ordinary sealant often gives a temporary effect, and then water begins to seep in again.
If the compressor works non-stop, trying to compensate for the heat influx, or, conversely, is silent, and there is heat in the chamber, these are signs of a deeper malfunction of the refrigeration circuit, and not just a problem with water drainage.
Why water leaks out from under the door?
Most often this happens due to the overflow of the drainage gutter. The water does not have time to go into the drainage and overflows. The second reason is the incorrect tilt of the refrigerator. If the front part is lower than the back, the water will flow out and not into the drainage hole.
Is it possible to use hot water to defrost ice in the drain?
Using boiling water is not recommended, as a sudden temperature change can cause cracks in the plastic. It is better to use warm water (about 40-50°C) or let the ice melt naturally with the refrigerator turned off.
How often do you need to defrost the Atlant refrigerator?
Models with a drip system require defrosting approximately once every 4-6 months, when the layer of ice on the back wall becomes noticeable. Models with No Frost are defrosted less frequently, usually once a year for hygienic cleaning, unless there is an emergency power outage.
