During operation household refrigerators of the brand Biryusa, especially the popular models of the 118 series, users often encounter strange plastic elements located in the rear of the unit. One of these elements is drainage insert, which plays a critical role in maintaining a normal microclimate inside the chamber. Many owners do not attach importance to it until they discover puddles of water on the floor or ice freezing where it should not be.
Understanding the operating principle of this part allows you to prevent many common malfunctions associated with excess moisture. In this article we will examine in detail where exactly condensate flows in Biryusa 118 models and why the integrity of this unit is so important for the durability of the compressor and interior decoration.
Ignoring the condition of the water drainage system can lead to corrosion of metal parts and the appearance of an unpleasant odor. Let's figure out how this system works and what to do if it stops functioning properly.
Design features of the Biryusa 118 model
The refrigerator Biryusa 118 refers to the classic two-chamber technology with a drip defrosting system. Unlike modern units with the No Frost system, here the process of moisture removal occurs naturally, which requires the presence of special gutters and channels. Drainage insert in this model it is a plastic element, often integrated into the back wall or located under the evaporator.
Its main task is to collect melt water that forms on the back wall of the refrigerator compartment during defrost cycles and direct it to the outlet. The design is made of frost-resistant plastic that can withstand temperature changes, but can become fragile over time. Violation of the geometry of the insert leads to the fact that water begins to flow down the inner surface of the chamber, bypassing the drain.
It is important to note that in different modifications of the 118 series, the shape of this element may differ slightly. Some versions have removable trays, others have a one-piece design with a body. In any case, the principle of operation remains unchanged: gravity forces the water to flow down, and the insert acts as a guide gutter.
The functional purpose of the drainage systems
The main function that drainage insertperforms is to prevent water from getting on shelves and products. During operation of the refrigerator, condensation forms on the cold rear wall. When the compressor turns off, the wall heats up and moisture flows down. Without a special gutter, water would spread over the entire bottom of the refrigerator compartment.
In addition, the system protects the thermal insulation layer. If water is not removed through the drain hole, it may penetrate behind the inner plastic of the case. Wet insulation loses its properties, which forces the compressor to work harder, increasing energy consumption. Biryusa 118 designed to minimize these risks, but only if all elements are in good working order.
Also, the drainage insert is involved in the hygiene of the device. Stagnant water is an ideal breeding ground for bacteria and mold. Proper removal of moisture into the pan located above the compressor, where it safely evaporates, ensures the absence of unpleasant odors inside the chamber.
- 💧 Collection of condensate: Localization of moisture in a narrow channel to prevent spreading.
- 🛡️ Insulation protection: Prevention of wetting of the polyurethane foam layer housing.
- 🦠 Hygiene: Quick removal of water eliminates the formation of mold and mucus.
⚠️ Attention: If you notice that water accumulates on the lower shelves or under vegetable drawers, First of all, check the condition of the drainage insert and the drain inlet. Often the problem is solved by simple cleaning, but if the plastic is cracked, replacement will be required.
Symptoms of malfunction and clogged drain
You can determine that drainage system is not working correctly by a number of characteristic signs. The most obvious of these is the appearance of water at the bottom of the refrigerator compartment or on the kitchen floor in front of the unit. Owners Biryusa 118 often notice that after defrosting or simply during work a puddle collects under the vegetable drawers.
Another symptom is the formation of a “coat” of ice not only on the back wall, but also in the lower part of the chamber, around the drain. This indicates that the water does not have time to leave and freezes, completely blocking the hole. Over time, the ice plug can grow and damage the plastic insert due to expansion when freezing.
An unpleasant musty odor that does not disappear after washing the shelves also indicates problems with moisture drainage. In stagnant water in the channel or a cracked insert, microorganisms begin to multiply. If you ignore these signals, you could end up with more serious problems, such as corrosion of metal parts or failure of electronics if water gets into it.
Instructions for cleaning and maintenance
Regular maintenance drainage insert and channel will extend the life of your refrigerator Biryusa 118. The cleaning procedure does not require complex tools or special skills. The main thing is to act carefully so as not to damage the plastic elements with sharp objects.
First you need to defrost the refrigerator. Unplug it and remove all food and shelves. Let the ice melt completely. After this, you can begin a visual inspection of the rear wall and drainage area. Often (a blockage) is visible to the naked eye - it is a lump of dirt, crumbs or frozen fat.
To clear the channel, you can use a special brush-brush, which is often included, or a soft wire with a bent end. Some users have success using a needle-less medical syringe filled with warm water to water hammer the clog. It is important not to use sharp metal objects that can puncture the tube or damage plastic insert.

Table of problems and solutions
Below is a table that will help you quickly diagnose a problem associated with moisture removal in refrigerators Biryusa. Use it as a reference material when the first signs of a malfunction appear.
| Symptom | Probable cause | Solution |
|---|---|---|
| Water on the floor in front refrigerator | Clogged drainage channel or displacement of the tube | Clean the channel, check the connection of the tube with the funnel |
| Ice in the lower part of the chamber | Water freezes at the mouth of the drain due to poor tightness | Thaw, check the integrity of the insert, replace if cracked |
| Unpleasant odor | Stagnation of water and proliferation of bacteria in the channel | Rinse the channel with a soda solution or a special product |
| Water shelves | Overflow of the insert due to the tilt of the refrigerator | Adjust the legs, set the horizon level |
It is important to understand that some problems can be caused not only by the breakdown of the insert itself, but also by improper operation. For example, if the refrigerator is tilted very backwards, water may flow out of the gutter faster than it goes down the drain. Adjusting the legs is a simple procedure that often solves the problem without replacing parts.
⚠️ Attention: When cleaning the drainage channel, it is strictly forbidden to use hot water (boiling water) to defrost the ice plug. A sharp temperature change can lead to cracking of the plastic insert or the internal contour of the refrigerator.
Replacing a damaged insert
If during the inspection you find that plastic insert has cracks, chips or is deformed, it must be replaced. It is not recommended to repair this element with glue or sealant, since in conditions of constant humidity and low temperatures the connection will quickly lose its tightness, and chemicals can be toxic.
To replace, you will need a new part compatible with the model Turk 118. It is better to look for the spare part article in the technical data sheet or markings on the back wall of the refrigerator. The replacement process usually involves dismantling the back panel inside the chamber (if the design allows) or carefully removing the old element.
When installing a new insert, make sure that it fits snugly against the wall and is correctly aligned with the hole in the drainage tube. Any gaps will lead to leaks. After installation, carry out a test run: pour a small amount of water into the gutter and make sure that it flows freely into the system.
Where can I find the spare part number?
The full part number is often indicated in the service documentation or on the spare parts manufacturer's website. Search for "drain funnel Biryusa 118" or "evaporator chute".
Prevention and durability of the system
To drainage system your refrigerator Biryusa 118 serve for a long time, it is enough to follow simple operating rules. Do not place hot foods in the chamber, as this causes excessive steam formation and overloads the moisture removal system. Also ensure the integrity of the product packaging - crumbs and debris should not fall on the back wall.
It is recommended to carry out preventive cleaning of the drain every 6-12 months, even if there are no visible problems. This will only take a few minutes, but will eliminate the risk of a sudden leak. Use mild detergents that do not contain abrasives to avoid scratching the plastic.
Timely maintenance is the key to the long life of your equipment. Drainage insert This is a small part with a big function, and attention to it will pay off in the absence of problems with water and odor in the future.
Is it possible to use wire to clean the drainage?
You can use wire, but with great care. It should be soft (for example, copper) and have a melted or bent end so as not to pierce the plastic tube that is located inside the case. It is better to use a special brush.
Why does the water in the drain freeze?
This happens if the refrigerator does not have time to defrost during the defrost cycle, or if the tightness of the door seal is broken, and warm, humid air enters the chamber. Also, the reason may be that the thermostat temperature is too low.
How to replace the drainage insert if there is no original?
Original spare parts are preferable. If you don’t have the original, you can try to select a universal gutter of the appropriate size or make a temporary analogue from food-grade plastic, but this requires skills and does not guarantee durability.
How often should Biryusa 118 be defrosted?
Models with a drip system, such as Biryusa 118, require defrosting approximately 2 times a year or as it forms ice more than 5-7 mm thick. Frequent defrosting reduces the load on the drainage system.
