Owners of domestic refrigeration equipment often encounter incomprehensible parts during disassembly or initial inspection of the unit. Drainage insert for refrigerator Biryusa 151 - this is precisely the element that raises questions during independent maintenance. This small plastic part plays a critical role in the moisture drainage system, preventing the appearance of puddles on the floor and inside the chamber.
Many users mistakenly believe that this component is decorative or secondary. In fact, without a properly functioning exhaust system condensationformed during the operation of the compressor, the operation of the equipment becomes impossible. Moisture simply will not go into the evaporator, which will lead to leaks and spoilage of products.
An understanding of the structure of this system is necessary for every owner of the model Biryusa 151. This knowledge will help you avoid costly repairs and extend the life of your refrigerator. Let's look in detail at how exactly this unit works and why it cannot be ignored.
The design and principle of operation of the moisture removal system
The system for removing excess moisture in refrigerators with drip defrosting, to which the model belongs Biryusa 151, is designed quite simply, but requires precise assembly. The main element here is a groove located on the back wall of the refrigerator compartment, into which water flows when the ice thaws.
The insert in question is located directly at the point of collection of liquid before it goes into the tube. It serves as a kind of coarse filter. Its shape is designed to collect water from a wide area of the gutter and direct it into the narrow opening of the drainage channel. adapter and a coarse filter. Its shape is designed to collect water from a wide area of the gutter and direct it into the narrow opening of the drainage channel.
If this element is displaced or damaged, water begins to overflow over the edge of the gutter. As a result, liquid ends up on food shelves or leaks out through the bottom of the door. This is why the integrity drainage funnel is so important for normal operation.
⚠️ Attention: When installing the insert, make sure that it fits snugly against the wall. The slightest gap can cause water to flow along the outside of the back panel, causing corrosion of the metal.
The principle of operation is based on gravity. Water flows by gravity through the insert and then through the tube enters a special container above the compressor, where it safely evaporates. Violation at any stage of this path leads to emergency situations.
Functional purpose of the plastic element
The main task of the drainage insert is to ensure unhindered flow of liquid. However, it also has a secondary, but no less important function - protecting the tube from clogging. Large particles of food, crumbs or mold are retained on the surface of this part without penetrating deeper into the system.
In addition, the insert prevents air from entering the drain tube, which could create an air lock. If there is a plug, the water will physically not be able to go down, even if the tube is clean. This creates an effect hydraulic sealthat disrupts circulation.
In the model Biryusa 151 this element also helps to evenly distribute the flow of water during intense ice melting. If you notice that water is standing in the groove and does not drain away, the problem may lie in the incorrect position of this component.
The absence or breakage of this part leads to the fact that moisture begins to accumulate in the wrong places. This is fraught not only with discomfort, but also with the risk of a short circuit if water reaches the electrical contacts.
Typical malfunctions and signs of blockage
The most common problem associated with the drainage system is its blockage. Over time, mucus, mold, and food debris accumulate in the tube and insert. This leads to the fact that the water stops draining.
The first sign of a malfunction is the appearance of a puddle under the vegetable drawers or right on the floor in front of the refrigerator. Ice may also be observed at the bottom of the rear wall of the refrigerator compartment, where water usually accumulates.
If you notice these symptoms, it is necessary to carry out a diagnosis. Often it is enough just to clean the hole, but sometimes it is necessary to completely disassembling the unit to eliminate the cause.
The table below shows the main symptoms and their possible causes associated with the drainage system:
| Symptom | Possible cause | Risk level |
|---|---|---|
| Water on the floor | Clogged tube or dislodged insert | High |
| Ice at the bottom of the chamber | Water does not drain and freezes | Average |
| Unpleasant odor | Bacterial proliferation in stagnant water | Average |
| Gurgling noise | Air lock in channel | Low |
Ignoring these signs can lead to more serious damage. For example, constant humidity contributes to the development of corrosion on metal shelves and body elements.
Instructions for cleaning and maintenance
You do not have to call a technician to remove the blockage. You can perform this procedure yourself, taking precautions. The first step should always be to disconnect the appliance from the power supply.
Next, you need to empty the refrigerator compartment of food and remove the shelves to gain access to the back wall. Locate the hole at the bottom of the gutter where the water drains. This is where the drainage insert is located drainage insert.
Carefully remove the plastic element. If it is secured tightly, do not use excessive force to avoid breaking the plastic, which becomes brittle in the cold. Allow the parts to warm up at room temperature.
☑️ Procedure for cleaning
Cleaning the channel itself can be done using soft wire or a special brush. Do not use sharp metal objects, as they can easily damage the inner walls of the tube or pierce the evaporator.
⚠️ Attention: It is strictly forbidden to use hot tap water for cleaning if the refrigerator has just been defrosted. A sudden change in temperature can lead to cracks in plastic or metal.
After cleaning all elements, reassemble the structure in reverse order. Make sure that the insert fits into place smoothly and fixes the water flow correctly.
Replacing a part in case of mechanical damage
Sometimes cleaning does not help if the part itself is damaged. Plastic loses its elasticity over time and may crack. In this case, you need replacement of the element a new one.
For the model Biryusa 151 you can try to find an original spare part by catalog number. However, due to the age of some modifications, the original may no longer be available. In such cases, owners often use universal solutions.
You can make a temporary plug from food-grade rubber or select an analogue from another refrigerator model. The main thing is that the diameter of the hole matches, and the shape allows water to drain without delay.
Where to look for the part number?
The original part number is often indicated on the plastic insert itself on the back side. If it is not there, refer to the spare parts catalogs for Biryusa series 151 refrigerators, looking for the diagram “Refrigerator compartment - interior design.”
When installing a new part, lubricate the edges of the hole with a small amount of food-grade silicone (after complete drying) to ensure a tight seal. This will prevent water from leaking past the funnel.
Prevention of blockages
In order not to encounter the problem of blockages regularly, you should follow simple operating rules. First of all, do not store food in the refrigerator without packaging. Crumbs and food particles are the main enemy of the drainage system.
Regular defrosting also helps keep the system clean. Even if you have a model with NoFrost in the freezer, the refrigerator compartment in Biryusa 151 requires periodic manual defrosting.
Once every six months, it is recommended to carry out preventive flushing of the drainage channel. To do this, you can use a blower with warm water, carefully pouring the liquid into the hole.
Watch the temperature. If the temperature in the chamber is too low, the water in the channel may freeze, forming an ice plug. The optimal temperature for the refrigerator compartment is +4...+5 degrees Celsius.
Frequently asked questions
Is it possible to operate the refrigerator without a drainage insert?
Technically, the refrigerator will work, but this will lead to constant water leaks onto the floor and inside the chamber. The insert is a mandatory design element for proper drainage.
What is the best way to clean the drainage tube?
The optimal tool is a soft cable for cleaning pipes or a long brush. You can use a syringe with warm water. It is better not to use chemicals so that their vapors do not reach the products.
Why does the water in the gutter freeze?
This happens if the drainage hole is clogged or frozen. The water does not have time to leave and turns into ice. Also, the cause may be a malfunction of the thermostat, which cools the chamber too much.
How often should you clean the drainage in Biryusa 151?
It is recommended to carry out preventive cleaning every 6 months or every time the refrigerator is completely defrosted. It will only take a few minutes, but it will save you from big problems.
