The appearance of a puddle under the lower shelves or directly in the niche for vegetables is a common problem faced by refrigerator owners Biryusa. Water can accumulate gradually, stagnate and emit an unpleasant odor, which jeopardizes the safety of food. Most often, the situation is associated with impaired air circulation or mechanical obstacles to the removal of condensate, but sometimes the reason lies in more complex malfunctions of the defrosting system.
Owners of units with manual defrosting or a system No Frost should pay close attention to the first signs of a leak. Ignoring the problem can lead to corrosion of the metal parts of the case, swelling of the internal plastic panel and failure of the electronic components located at the bottom of the device. Understanding the moisture drainage device will help you quickly diagnose and fix the problem on your own.
The following material will help you determine the exact cause of water formation in your particular case. We will consider both simple blockages that can be removed in 10 minutes, as well as complex technical breakdowns that require the intervention of a specialist or replacement of parts. It is important to act consistently so as not to damage the fragile elements of the internal chamber.
⚠️ Attention: Before starting any diagnostic or repair work, be sure to disconnect the refrigerator from the electrical network. Working with electrical appliances under voltage is prohibited by safety rules.
The principle of operation of the condensate drainage system
To understand why the water is not where it should be, it is necessary to briefly consider the physics of the process. During operation of the compressor, frost or condensation forms on the rear wall of the refrigerator compartment. In models with a drip defrosting system or Low Frost moisture flows down a groove into a special drainage hole. Then, through the tube, it enters the container above the compressor, where it safely evaporates.
If this well-functioning mechanism fails, the water has nowhere to go except to spread along the bottom of the chamber and accumulate in the recesses under the fruit boxes. In refrigerators Biryusa it is structurally provided that the bottom of the chamber has a slight slope towards the drain hole. However, over time, the geometry may be disrupted, or the path of water may be blocked by foreign objects.
Particular attention should be paid to the temperature regime. If the thermostat is set to maximum cooling, the back wall may freeze through, turning the drainage channel into an ice plug. In this case, the condensate does not have time to drain and overflows over the sides of the gutter, ending up on the shelf below.
- 💧 Water should normally evaporate in the tray above the motor, without requiring manual removal.
- ❄️ The formation of an ice crust on the back wall is the first sign of problems with moisture removal.
- 🌡️ Incorrect thermostat settings often provoke excessive condensation.
Clogged drainage hole as the main reason
The most likely reason why there is water in the refrigerator Biryusa is a banal blockage of the drainage channel. During operation, crumbs, packaging particles, lint or sticky food residues get into the drain hole. Over time, this debris becomes compacted and completely blocks the flow of fluid. Water begins to rise up the gutter and flow out over the edge.
To clean the channel you will need a thin flexible wire (for example, for cleaning pipes) or a special brush-brush. Some models Biryusa are equipped with a plastic pin built directly into the hole, which you simply need to remove, clean and insert back. If there is no such device, you can use a soft wire with a bent end, but you should act extremely carefully so as not to pierce the heat insulator.
After mechanical cleaning, it is recommended to rinse the channel with warm water. It is most convenient to use a medical bulb or syringe without a needle. Pour water into the hole and watch if it goes quickly to the bottom of the housing. If the water stands still, the procedure must be repeated. Sometimes several washing cycles are required to completely dissolve fatty deposits inside the tube.
☑️ Cleaning the drainage
What is the danger of ignoring the blockage?
If you do not clear the drainage, water can leak under the internal plastic. In winter, this moisture will freeze, expanding and deforming the plastic liner of the camera. Repairing such deformation is complex and requires complete disassembly of the refrigerator or replacement of the internal chamber.
The problem of freezing and malfunction of the defrost system
The situation when water accumulates under the drawers is often associated with cyclic freezing and thawing of the drainage. In refrigerators with a No Frost or Low Frost system, a heating element (heating element), a defrost timer and a temperature sensor are responsible for water removal. If one of these components fails, the ice stops melting normally, building up in the evaporator.
If the defrost heating element or timer malfunctions, the ice block may partially melt when the door is opened or during rare operation cycles, but the main volume of water does not have time to evaporate. As a result, during the next defrosting, the volume of water becomes critical, the drainage tube in the freezer area (where there is always a minus) freezes, and melt water pours directly onto the food or under the drawers.
Diagnostics of this problem requires a multimeter. It is necessary to “ring” the heating element for an open circuit. It is also worth checking the defrost sensor, which should open the circuit when a certain temperature is reached. If these elements are in good working order, but the problem persists, the defrost timer itself may have failed and simply does not start the defrost cycle.
| System component | Fault symptom | Check method |
|---|---|---|
| Defrost heating element | Ice does not melt, water does not flow into the drain | Ring with a multimeter (there should be resistance) |
| Defrost timer | The refrigerator does not go into defrost mode | Checking contacts and clicks when scroll |
| Defrost sensor | The heating element does not turn on or constantly heats | Resistance measurement at different temperatures |
| Drain tube | Water flows past the hole | Visual inspection and purge |
If you find that the back wall in the freezer (behind the plastic panel) is covered with a thick layer of ice or snow, and there is water under the drawers in the refrigerator compartment, this is almost guaranteed to be a system problem. No Frost. In such cases, simply cleaning the drainage will only give a temporary effect until the ice again blocks the path of water.
Deformation of the case and violation of the geometry
Refrigerators Turquoise, especially models from previous years of production or budget series, may suffer from deformation of the internal plastic liner. This occurs due to temperature changes, mechanical pressure (if you lean on a shelf) or manufacturing defects. As a result, the bottom of the chamber warps, and the slope necessary for water to flow to the drainage hole disappears or changes direction.
Water begins to accumulate at the lowest point, which is now not at the drain, but in the middle or at the back wall, from where it flows under the vegetable boxes. This can be seen visually if you pour a little water onto the bottom of an empty refrigerator and watch its movement. If it does not flow to the hole, then the geometry is broken.
To correct the situation, sometimes it is enough to place small wedges under the supports of the refrigerator to change the angle of inclination of the entire body in space. However, if the plastic itself is deformed, it will require dismantling, heating (carefully!) and leveling, or replacing the internal chamber, which is not always economically feasible.
Improper operation and storage of products
Often the reason is trivial and lies in the actions of users. Storing food in open containers, hot pots, or liquids without lids causes the humidity inside the chamber to rise sharply. The moisture removal system simply cannot cope with such a volume of steam, which condenses on the walls and bottom in large quantities.
It is also worth checking the tightness of the rubber seals on the doors. If the seal is dirty, damaged, or the door is warped, warm, moist air constantly enters the chamber. This leads to increased formation of condensation, which settles on the food and the bottom of the refrigerator.
- 🍲 Do not place hot foods in the refrigerator, let them cool to room temperature.
- 🥛 Use lids for all containers with liquid to minimize evaporation.
- 🚪 Regularly wipe the seals and check the tightness of the door with a sheet of paper.
⚠️ Attention: Excessive loading of the refrigerator with food tightly pressed to the back wall disrupts the circulation of cold air. This can lead to local freezing of the wall and blocking the flow of water. Leave a gap of 2-3 cm at the back panel.
Mechanical damage and foreign objects
Water under the drawers may appear due to a large foreign object getting into the drainage chute: a fruit pit, a piece of glass, a label or a piece of frozen food. Unlike small debris, such objects cannot be pushed further along the tube, and they create a dull plug.
In addition, it is worth inspecting the water collection tray (bath) above the compressor, if you have access to the rear panel. If it is cracked or misaligned, water will drip past, pooling on the floor or pooling at the bottom of the cabinet, creating the illusion of a leak from the inside. In older models Biryusa the plastic of the trays could dry out over time.
Sometimes the reason is the displacement of the shelf itself above the drawers. If it is skewed, condensation dripping from the top shelf or wall may not fall into the gutter, but past it, flowing directly onto or under the vegetables. Check the horizontal installation of all glass shelves and plastic sides.
Frequently asked questions and answers (FAQ)
Is it possible to use hot water to defrost ice in the drain?
It is not recommended to use boiling water, since a sharp temperature change can lead to cracks in the plastic of the inner liner. It is better to use warm water (about 40-50 degrees) and a syringe. If the ice jam is serious, it is better to wait for the refrigerator to naturally defrost while it is turned off.
Why does water appear only in summer?
In the hot season, the air humidity in the room is higher, and the refrigerator compressor works more intensely. This leads to an increase in the volume of condensate. If the drainage system has slight contamination, in summer the throughput may not be enough, and water begins to overflow over the edge of the gutter.
What to do if the drainage hole is too deep?
In some models Turk the entrance to the drainage is located deep. For cleaning, you can use a long soft brush for cleaning bottles or a piece of internet wire (twisted pair), removing the insulation from it. The main thing is not to use sharp metal objects that can damage the tube.
Is it normal that the water in the tray above the compressor sometimes does not have time to evaporate?
During periods of high humidity or after loading a large number of products, the volume of water may exceed the evaporation rate. If the water does not overflow over the edge of the tray onto the floor, this is acceptable. However, a constant excess of water indicates that too much moisture is getting into the chamber (a problem with the seal or user habits).
