Owners of refrigeration equipment brands Turk often encounter a situation where water begins to accumulate inside the chamber. Puddles on shelves or under vegetable drawers are not just an inconvenience, but a signal of a malfunction of the condensate drainage system. The key element responsible for the normal removal of moisture is drainage insertlocated on the back wall.
Understanding how this part is designed and why it ceases to perform its functions allows you to quickly fix the problem on your own. In most cases, water comes out due to a simple blockage or the formation of an ice plug in the drain channel. Let's look in detail at what it is drainage hole and how to properly maintain this unit.
Ignoring the first signs of a malfunction can lead to more serious consequences, such as failure compressor or damage to the interior of the camera. Water, unable to find a way out, flows onto the housing, causing corrosion, or freezes, blocking the operation of the evaporator. Therefore, timely diagnosis of the drainage condition is an essential part of equipment care.
The design and principle of operation of the drainage system
The moisture removal system in refrigerators Biryusa with drip defrosting is quite simple, but requires careful attention. At the bottom of the rear wall of the refrigerator compartment there is a small hole that leads into a tube that goes into a special container above the compressor. This is where the water generated on the evaporator flows during operation of the unit. Drainage insert or the neck of this hole is often equipped with a plastic element that prevents large debris from getting inside the tube.
The principle of operation is based on gravity: the condensate flows down by gravity. However, if an obstruction occurs in the system, water begins to accumulate at the bottom of the chamber. The critical point is the formation of an ice plug directly at the exit from the chamber, which completely blocks the drain. This often happens due to improper operation or too low a temperature.
It is important to note that in some models Biryusa the design may not have a removable plastic insert, but may simply be a molded hole in the plastic of the inner wall. In such cases, the role of the “insert” is played by the channel geometry itself. For effective operation, it is necessary that drainage channel be free from foreign objects.
Why may the insert be missing?
In older models of Biryusa refrigerators, the plastic removable insert is often missing provided for by the design. The hole was simply part of the back wall molding. In modern versions, manufacturers add removable elements to facilitate cleaning.
Main causes of clogging and the appearance of water
There are several key factors that lead to impaired moisture removal. Most often the problem lies in the physical design of the channel. Food crumbs, packaging or labels can accidentally fall into the drain area and get stuck there, creating a blockage. Over time, mucus or ice builds up around this debris, finally blocking the path of water.
Another common reason is a violation of the temperature regime. If you set the temperature in the refrigerator compartment too low, the moisture will freeze faster than it can drain. Ice coat on the back wall it also covers the entrance to the drainage hole. This is also facilitated by frequently opening the door or placing hot foods inside, which sharply increases the humidity.
- 🧊 Freezing: formation of an ice plug due to low temperature or malfunction of the defrost sensor.
- 🍞 Food debris: crumbs, lettuce or pieces of foil that have fallen into the drain.
- 🦠 Biological plaque: mold and mucus, which narrow the lumen of the tube and impede the flow of liquid.
- 🔧 Tube displacement: mechanical damage or displacement of the drainage hose inside housing.
It is also worth mentioning manufacturing defects or transportation errors. If the refrigerator was transported lying down without observing the time intervals, oil could get into the system, which sometimes affects the operation of the components, although this less often concerns drainage. Most often, the culprit is frozen condensate.
Instructions for cleaning the drainage hole
Before starting any work, you must turn off the power to the refrigerator. This is a safety requirement and a necessary condition for defrosting ice if it has caused a blockage. Leave the unit turned off for at least 10-12 hours so that all the ice inside has time to melt naturally. Using a hairdryer or hot objects to speed up the process is not recommended, as it can damage plastic parts or the evaporator.
After complete defrosting and removal of water from the bottom of the chamber, you can begin mechanical cleaning. You will need a soft wire (for example, from a phone charger), a bottle brush or a special flexible brush. Carefully insert the tool into drain hole, making rotational movements to break the plug. Do not use excessive force to avoid puncturing the tube.
To disinfect and remove grease deposits, you can use a solution of warm water with a small amount of baking soda or a mild detergent. Pour the solution into the hole using a syringe or bulb, wait a few minutes, and then rinse with clean water. Make sure that water flows freely into the container above the compressor.

Technical characteristics and replacement of elements
In some cases, simple cleaning does not help, and replacement of damaged elements is required. If the plastic drainage insert is cracked or deformed, it may leak air, impairing circulation, or simply interfere with cleaning. In models Biryusa these parts are often part of the internal lining, but there are also removable plugs.
When ordering spare parts, it is important to take into account the model of the refrigerator. The design of the drain may vary depending on the year of manufacture and series. Below is a table with indicative parameters for various modifications so that you can navigate in finding the right part or repair method.
| Element type | Material | Typical diameter | Replacement frequency |
|---|---|---|---|
| Removable insert | ABS plastic | 10-15 mm | Rarely, if broken |
| Drain tube | Polyethylene | 8-12 mm | Only if damaged |
| Evaporator tray | Metal/Plastic | Depends on models | In case of corrosion |
| Neck seal | Rubber | Standard | In case of loss of elasticity |
If you find that the tube coming from the hole is cracked or disconnected inside the housing, partial disassembly of the rear wall of the refrigerator compartment will be required. This is a more complex procedure that requires care when working with thermal insulation and panel fastenings.
Preventing the formation of ice jams
To prevent the water problem from recurring regularly, it is important to follow the operating rules. Do not place hot pots or food that has not cooled to room temperature in the refrigerator. Excess steam instantly condenses on the cold walls and freezes in the zone drainage channel. Also, make sure that the door is tightly sealed: if the seal is worn out, warm, moist air constantly enters the chamber.
Regularly check the condition of the rear wall. If you notice a build-up of “fur coat” around the drain hole, this is the first signal of incipient problems. Easy maintenance cleaning is enough to avoid large-scale defrosting. Use a soft cloth to wipe the area around the drain hole once a month.
⚠️ Attention: Never use sharp metal objects (knives, screwdrivers) to pick at ice in the drain hole. There is a high risk of piercing the evaporator wall or damaging the tube, which will lead to freon leakage and costly repairs.
Another tip concerns the placement of products. Try not to store vegetables and fruits in close proximity to the back wall where the opening is located. Small particles of peel or juice can get into the drain and become the basis for the formation of a blockage.
When specialist help is required
Despite the fact that cleaning the drainage is a procedure accessible to everyone, There are situations when you can’t do it on your own. If water continues to accumulate after thorough rinsing and defrosting, the problem may lie deeper. This may be a malfunction of defrost system, heating element or timer, due to which the ice freezes faster than it has time to melt.
Also, the help of a technician is necessary if you suspect a refrigerant leak. If there is a lack of freon, the refrigerator can work non-stop, causing severe freezing of the evaporator and clogging of the drain with ice. Diagnostics of pressure in the system and checking the tightness of the circuit require special equipment.
- 🛠️ Mechanical damage: if you accidentally pierced a tube or wall during cleaning.
- ❄️ Constant freezing: ice forms again a few hours after defrosting.
- 🔊 Extraneous sounds: gurgling or noise indicating problems with refrigerant circulation.
- 💧 Water outside: if water flows not only inside, but also flows out under the refrigerator onto the floor.
In such cases, independent repairs can lead to the final failure of the equipment. A professional technician will be able to accurately determine whether this is the cause drainage insert or the problem is systemic.
⚠️ Attention: If you notice oily stains around the drain hole or smell a specific chemical odor, stop using immediately and call a specialist. This may indicate a serious leak of oil from the compressor along with freon.
Frequently asked questions (FAQ)
Is it possible to drip boiling water into the drainage hole for defrosting?
It is not recommended to use boiling water, since a sharp temperature change can deform the plastic tube or damage the inner lining of the camera. It is better to use warm water (40-50 degrees) and give it time to act.
How can you tell that the drainage tube inside the case is intact?
A simple way to check is to pour about 100-200 ml of water into the hole. If it quickly disappears and does not flow back, then the channel is free. If there is water in the neck, there is a blockage. If you hear gurgling at the bottom (above the compressor), it means that the tube is intact and the water is reaching the tray.
Do you need to lubricate the drainage insert with oil?
No, you don’t need to lubricate anything. Oil can attract dust and create a sticky film that will only make the clog worse. Clean and smooth walls are the main condition for good permeability.
Why does the Biryusa refrigerator with No Frost also have a drainage hole?
In the No Frost system, drainage is also necessary to remove condensate that forms on the evaporator during defrost cycles. The principle of its operation is similar, but it is often located hidden behind the back panel inside the freezer or refrigerator compartment.
What is the best way to clean a narrow channel?
The optimal tool is a special brush for cleaning drainage (sold in hardware stores) or a soft wire with a piece of cotton wool wound at the end. Hard brushes can scratch the plastic, creating roughness for dirt to stick.
