Did you open the refrigerator Biryusato get vegetables and find a puddle under the plastic drawers? This problem is familiar to many owners of domestic refrigerators. The accumulation of water not only creates discomfort during cleaning, but also signals possible malfunctions in the cooling system or drainage. In most cases, the cause can be eliminated on your own - without calling a specialist and costly repairs.
In this article we will analyze all possible reasons for the appearance of water under the drawers refrigerators Biryusa (including models with the system No Frost and drip defrosting), give Step-by-step instructions for diagnosis and repair, and we will also tell you when professional help is really needed. We will pay special attention to typical user mistakes that lead to repeated accumulation of moisture.
Spoiler: in 80% of cases the problem is solved by cleaning the drainage hole or adjusting the temperature regime. But there are also more serious breakdowns - for example, a thermostat failure or a clogged evaporator. To avoid aggravating the situation, read the article to the end!
1. A clogged drainage hole is the most common cause
In refrigerators Biryusa with a drip defrosting system (models Biryusa 10, 12, 14, 18, 22 etc.), condensate flows down the back wall into a special drainage hole, and from there into the tray above the compressor. If this hole becomes clogged with crumbs, food particles or mold, water begins to accumulate at the bottom of the chamber and leaks under the drawers.
How to check: Open the refrigerator and inspect the back wall. If ice or dirt is visible under the hole (usually located centrally above the vegetable rack), the cause has been found. In models with No Frost the drainage may become clogged less frequently, but is also not immune from this problem.
- 🧊 Ice in the drainage - formed due to rare defrosting or high humidity in the chamber.
- 🍞 Crumbs and debris - get through careless cleaning or storing open products.
- 🍄 Mold and slime - multiply in a warm, humid environment if the drainage has not been cleaned for a long time.
To clean the hole, take cotton swab, syringe or thin wire. Carefully remove any visible debris, then wash the drain with warm water and soap. For disinfection, you can use a soda solution (1 tablespoon per 200 ml of water).

2. Incorrect installation of the refrigerator: tilt and vibrations
If the refrigerator Turk is not level, the door may not fit tightly, allowing warm air to pass through. This leads to formation of excess condensationwhich does not have time to evaporate and flows under the boxes. In addition, vibrations during compressor operation can displace the water collection tray, causing leaks.
How to check the tilt: take a building level and place it on the top lid of the refrigerator. If the bubble is displaced by more than 2°, the legs need to be adjusted. In models Turk 6M, 8M, 10M the front legs are adjusted by turning counterclockwise (for raising) or clockwise (for lowering).
| Sign | Possible problem | Solution |
|---|---|---|
| The door opens itself when slightly tilted | The refrigerator is tilted forward | Twist the front legs all the way |
| Vibration and rattling noise during compressor operation | Uneven floor or weak fixation of legs | Level the floor or place anti-vibration pads |
| Water accumulates on one side of the tray | The refrigerator is tilted left/right | Adjust the side legs or place a pad |
Please note: if the floor in the kitchen is uneven (for example, the tiles are laid on a slope), even adjusting the legs may not help. In this case, use anti-vibration stands or special gaskets under the legs.
3. Problems with the door seal: cracks and deformation
The rubber seal (or, as it is called in the documentation Biryusa, sealing cuff) loses elasticity over time, cracks or moves away from the body. This leads to a constant flow of warm airwhich causes the compressor to work longer, and excess condensation forms on the back wall.
How to diagnose:
- Carefully inspect the seal around the entire perimeter. Look cracks, tears, or areas where the rubber has separated from the plastic.
- Close the door and shine a flashlight inside the refrigerator. If light leaks into the cracks, the seal is not airtight.
- Check the magnetic fit: close the door on a piece of paper. If the sheet falls out, the seal is worn out.
In models Biryusa older than 5 years, the seal often requires replacement. A new one can be ordered by article number (for example, for Biryusa 18C a seal is suitable BR-18-UPL). If the deformation is minor, try restore elasticity:
- 🧴 Lubricate seal silicone grease (do not use vegetable oil!).
- 🔥 Warm the elastic with a hair dryer at minimum temperature (keep at a distance of 20 cm).
- 🧲 Place it under the magnetic tape a thin strip of paper for a better fit.

4. Malfunction of the thermostat or temperature sensor
If the refrigerator Biryusa works without stopping or, conversely, turns on too rarely, the problem may lie in thermostat (in mechanical models) or temperature sensor (in electronic ones). These parts are responsible for maintaining the given mode. If they break down, the compressor either works ineffectively or freezes the chamber, which leads to ice formation and subsequent leaks.
Signs of a thermostat malfunction:
- ❄️ A thick layer of ice (more than 5 mm) forms on the back wall.
- 🔥 The refrigerator does not cool to the set temperature (for example, at +5°C the display actually shows +10°C).
- ⚡ The compressor turns on for 2-3 seconds and immediately turns off (relay clicks).
To diagnose the thermostat in mechanical models (Biryusa 6, 8, 10), turn the temperature adjustment knob to maximum. If the compressor does not turn on, the thermostat is faulty. In electronic models (Biryusa 22, 26 with a display), the sensor error is usually displayed by code E1 or E2.
⚠️ Attention: Replacing the thermostat requires partial disassembly of the refrigerator. If you are not confident in your skills, contact a service center. Incorrect installation can lead to short circuit or leakage of freon.
5. Clogging or freezing of the evaporator in No Frost systems
In refrigerators Biryusa with the system No Frost (models Biryusa 22NF, 26NF), water may appear under the drawers due to a malfunction of the evaporator defrost. In normal mode, the fan blows on the evaporator, and melt water flows into the drain. If the defrost system fails, the evaporator freezes over, and the ice begins to melt uncontrollably, flowing past the drainage.
Causes of evaporator freezing:
- 🔥 The defrost heating element is burnt out —a heater that melts the ice on the evaporator.
- 🕒 The defrost timer is faulty —the heating element does not turn on at the right time.
- 🌡️ The defrost sensor has failed (defroster).
For diagnostics, turn off the refrigerator for 12-24 hours so that the ice melts. If after switching on the problem recurs, the faulty element must be replaced. In models Biryusa No Frost The defrost heating element is located behind the rear panel of the freezer (accessed after removing the lid).
How to check the defrosting heating element with a multimeter
Unplug the refrigerator and defrost it. Remove the back panel of the freezer to gain access to the heating element. Set the multimeter to resistance measurement mode (200 ohms). Touch the probes to the contacts of the heating element. If the resistance tends to infinity (OL), the heating element has burned out and requires replacement. Normal resistance for the heating element of Biryusa refrigerators: 200–500 Ohm.
6. Overloading the refrigerator with food or improper storage
It would seem that what is common between the accumulation of water and the amount of food? Actually - direct connection. If the refrigerator Turk is packed to capacity, air circulation is disrupted, and warm streams from food condense on the back wall. In addition, some products (for example, fresh vegetables in open bags) release moisture, which settles below.
Typical storage errors:
- 🥬 Storing vegetables in plastic bags without ventilation.
- 🍲 Hot foods are placed in the refrigerator without cooling.
- 🥛 Bottles and cans are placed too close to the back wall.
To reduce condensation:
- Place food so that there is space between them for air circulation.
- Use containers with lids for storing vegetables and fruits.
- Do not place warm or hot foods in the refrigerator - let them cool to room temperature.
7. Mechanical damage: cracks in the pan or tubes
If all previous causes are excluded, but water continues to accumulate under the boxes, inspect condensation tray and drainage tubes. In refrigerators Biryusa the tray is located above the compressor (accessible from the rear wall). Over time, the plastic may crack, especially if the refrigerator is often moved or washed with aggressive detergents.
How to detect damage:
- Unplug the refrigerator and carefully move it away from the wall.
- Remove the bottom decorative panel (usually secured with latches or screws).
- Inspect the pan and tubes for cracks, breaks, or signs of leaks.
If the pan is cracked, it can be replaced (article number for most models - BR-PAN). A damaged drainage tube can be temporarily insulated heat-shrinkable tube or silicone sealant, but it is better to replace it with a new one.
⚠️ Attention: When working with drainage pipes, do not use cyanoacrylate-based glue (for example, “Superglue”). It can dissolve from contact with water and cause repeated leakage.
FAQ: Frequently asked questions about water in the Biryusa refrigerator
Is it possible to use the refrigerator if water accumulates under the drawers, but it continues to freeze?
Short-term - yes, but the problem will not go away on its own. Constant moisture leads to mold growthcorrosion of metal parts and increased load on the compressor. We recommend eliminating the cause within 1–2 weeks.
How often should you clean the drainage hole in the Biryusa refrigerator?
Ideally - once every 3-6 months. If open foods are often stored in the refrigerator (for example, bulk cereals, flour), cleaning should be done monthly. Use cotton swabs or special brushes for drainage.
Why did water appear again under the drawers after defrosting?
Probable reasons:
- The drainage hole is not completely cleaned (ice plugs remain).
- The water collection tray is installed crookedly or cracked.
- The door seal did not restore tightness after defrosting.
Repeat the diagnostics according to the instructions from the article.
Is it worth repairing the old Biryusa or is it better to buy a new one?
If the refrigerator is older than 10–15 years, and the problem is related to freon leakage or compressor breakdown, repairs may cost 50–70% of the cost of a new device. In this case, it makes more sense to consider a replacement. For models under 5 years old, repair is almost always more profitable.
Is it possible to replace the defrost heating element yourself in No Frost?
Theoretically, yes, but this requires disassembling the freezer work with electrical contacts. Without experience, there is a risk of damaging the evaporator or freon line. If you are not sure, contact the service.
