Detecting a puddle in the kitchen or water directly inside the refrigerator compartment is a situation that makes any owner of household appliances panic. It is especially unpleasant when this happens to a reliable Belarusian brand Atlant, known for its resource. However, before calling a technician, it is necessary to carry out an initial diagnosis, since in 60% of cases the problem is solved without purchasing expensive spare parts.
The main reason lies in the disruption of air circulation or condensate drainage. Moisture may appear due to a banal blockage or signal a failure defrost systems. Understanding the operating principle of your model will help you quickly localize the fault and save your budget.
In this article we will analyze in detail the mechanical and electrical causes of leaks. You will learn how to properly clean the drainage hole, check the serviceability of the sensors and understand when the unit really needs serious repairs.
Violation of temperature conditions and operating rules
The most common reason for the appearance of water at the bottom of the refrigerator compartment or under vegetable boxes is a simple failure to comply with the rules for storing food. When you put hot soups or simply cold dishes into the chamber, the temperature inside rises sharply. The sensors detect the heating, and the compressor begins to work in increased mode, which leads to the formation of an excessive amount of condensate.
The moisture removal system simply does not have time to cope with such a volume of liquid. Water flows down the back wall, but does not go into the drain, but overflows through the groove and accumulates at the bottom. Also, the problem may lie in poor fit of the door. If the rubber seal is dirty or damaged, warm air from the room constantly gets in.
Moisture settles on the walls, freezes, forming an ice crust, which then melts faster than it can evaporate or go down the drain. Check to see if food is preventing the door from closing tightly. Often, a bottle standing at the very edge of the shelf does not allow the seal to press tightly against the body.
- ❄️ Check the temperature in the chamber - it should not be higher than +5°C.
- 🚪 Inspect the rubber seal for cracks and adhering dirt.
- 🥘 Make sure food has cooled to room temperature before placing it in the refrigerator.
Pay attention to the position of food against the back wall. If food bags fit tightly against the back panel, they restrict air circulation. In this place, local hypothermia occurs, the products freeze to the wall, and during defrosting a puddle forms. The gap between the products and the back wall must be at least 2-3 centimeters for normal operation of the No Frost or drip system.
Drain hole clogged
If you We are sure that the operating rules have not been violated, and the ice crust on the back wall melts and turns into a puddle, most likely the culprit clogged drainage channel. In refrigerators with a drip defrost system (weeping wall), condensate flows into a special groove at the bottom of the rear panel. From there, through the hole, the water goes into the container above the compressor, where it safely evaporates.
Over time, crumbs, mold, mucus or pieces of food accumulate in this hole. The throughput of the channel drops, and water begins to overflow over the edge of the groove, flowing onto the shelves and the bottom of the chamber. This is a classic situation when Atlant refrigerator “cries” too much.
⚠️ Attention: It is strictly forbidden to use sharp metal objects (knives, knitting needles, wire) to clean the drainage. You can damage the inner tube hidden in the housing, which will lead to freon leakage and expensive system repairs.For cleaning, use a soft wire with a curved end, a bottle brush or a medical syringe with warm water. Gently push through the clog and flush the drain. If the water begins to drain with a characteristic gurgle, the problem is solved.
☑️ Algorithm for cleaning the drainage
Done: 0 / 4In some models, access to drainage may be difficult. In this case, you can use a flexible wire from a USB cable (after cutting off the connector) or a special flexible cable. The main thing is to act without fanaticism, so as not to break through the plastic.
Malfunctions of the defrosting system (heating element, timer, sensor)
In models with the system No Frost the situation is more complicated. Here, water should not appear in principle, since the evaporator is located in a hidden compartment. If you see water at the bottom of the refrigerator or freezer, this often indicates a failure in the defrost cycle.
The defrost system consists of a heating element (heating element), a defrost sensor and a timer (or electronic control module). If the heating element is burnt out, the ice on the evaporator does not melt during a pause in the compressor operation. It grows, turning into a huge snowdrift. When the layer of ice becomes too large, the fan stops moving air, and during rare defrosts or failures, this ice melts unevenly and water pours into the chamber, bypassing the pan.
How to check the defrost heating element with a multimeter?
To check, you need to get to the evaporator (remove the back panel in the freezer). Disconnect the contacts of the heating element and ring them with a tester in resistance measurement mode. If the device shows “infinity” or one, the circuit is broken, the heating element has burned out and requires replacement. Normal resistance is usually from 200 to 500 Ohms.
Also often fails defrost sensor. It should “feel” when the ice has melted and turn off the heating. If the sensor is “stuck” in the “defrosting is completed” position, the heating element may not turn on at all. Or, conversely, do not turn off, which will lead to overheating and melting of the plastic.
Diagnostics of these elements requires disassembling the internal part of the unit. You will need to remove the back panel in the freezer to visualize the condition of the evaporator. If you see a coat of ice covering the fan, there is a problem in the defrost system.
- 🔥 Defrost heating element - a heating element that melts the ice on the evaporator.
- 🌡️ Defrost sensor - a thermostat that controls the temperature of the evaporator.
- ⏱️ Defrost timer is a mechanical or electronic device that sets defrosting cycles.
Displacement or damage to the drainage tray
Sometimes water in the refrigerator Atlant appears due to a banal displacement of the condensate tray. This plastic piece is located above the compressor at the lower rear of the unit. During vibration during motor operation or during careless transportation, the tray may move to the side.
As a result, the drainage tube no longer fits exactly into the receiving hole of the tray. Drops of water begin to drip past, flowing onto the floor or onto the compressor itself, causing corrosion and an unpleasant odor. To check this, move the refrigerator away from the wall and look at the lower part at the back.
If the tray is misaligned, you just need to adjust it. However, if you notice cracks in the plastic (they often appear due to age or temperature changes), the tray will have to be replaced or carefully soldered. Plastic becomes brittle over timeso proceed with caution.
Also check that the refrigerator itself is installed horizontally. If the unit is tilted backwards, water may not flow into the drainage hole, but may pour forward onto the shelf. Use a building level to check. The height is adjusted using the front support legs.
Technical faults: thermostat and control module
If mechanical causes are excluded and the drainage is clean, you should pay attention to the electronics. Faulty thermostat (thermostat) may not give the compressor a command to stop. The refrigerator works without interruption, the back wall is covered with a thick layer of ice. When you open the door or a natural but insufficient defrost occurs, this ice turns into a huge amount of water.
In modern electronically controlled models, the problem may be control module. Failures in the firmware or oxidation of contacts on the board can lead to incorrect operating cycles. For example, the module may “forget” to turn on the defrost mode at the right time.
Symptom Probable cause Solution method The refrigerator is not turns off, ice behind Thermostat or sensor is faulty Replacing the thermostat Water only after defrosting Drainage clogged Cleaning the channel Ice in the freezer, water below The defrost heating element is burnt out Replacing the heating element Water under the refrigerator The tray is displaced or the hose is cracked Adjust the tray/replace the hose Diagnostics of electronic components requires special knowledge and tools. If you do not have the skills to work with electrical circuits, it is better to entrust this work to a specialist. Replacing the control module yourself may not be economically feasible.
⚠️ Attention: Before any work related to disassembling the case or checking electrical contacts, be sure to disconnect the refrigerator from the power supply. Working with live electrical appliances is life-threatening!When you need to call a specialist
Not all problems can be solved with your own hands. If you have checked the drainage, temperature, position of the tray and the tightness of the door closure, but water continues to collect, it is probably a hidden freon leak or a compressor breakdown, although this is less typical for leaks than for the absence of cold.
However, if we are talking about replacing the heating element, defrost timer or thermostat, and you do not have disassembly experience Atlant, it’s better to call a specialist. Incorrect assembly can lead to damage to the plastic fasteners, which then cannot be restored.
Also, the help of a specialist is needed if you hear extraneous noise, humming, or you see that the compressor is working intermittently. Comprehensive diagnostics will allow you to accurately identify a failed unit and avoid unnecessary expenses on replacing parts “at random.”
Is it possible to operate a refrigerator if water collects in it?
Short-term operation is possible, but undesirable. Constant moisture promotes the growth of bacteria and mold, which is dangerous for food. In addition, water can flow into electrical contacts or cause corrosion of metal parts of the case and shelves.
How often do you need to defrost the Atlant refrigerator?
Models with a drip system require defrosting 1-2 times a year. No Frost systems do not formally require defrosting, but experts recommend carrying out preventive defrosting once a year to clean out bacteria and check drainage.
Why does water appear only in summer?
In summer, air humidity is higher, and more heat enters the room when the door is opened. The drainage system may not be able to cope with the increased volume of condensate, especially if there is a slight tilt of the refrigerator or a microscopic blockage.
What to do if the drainage is frozen?
If the drainage hole is covered with ice, you need to carefully defrost it. You can use a rubber bulb with warm (not boiling water!) water. You cannot pour boiling water into a plastic channel - you can deform the plastic.
