The appearance of a puddle under vegetable boxes or at the bottom of the refrigerator is a signal that cannot be ignored. Owners of Korean brand equipment Daewoo often encounter the fact that the moisture removal system ceases to cope with its task. Water begins to accumulate on the floor, creating the risk of flooding the kitchen and damaging the flooring.
The main reason for this behavior lies in the blockage of the channel through which the condensate should go to the evaporator. Understanding where is the drainage hole and how it works is the first step to troubleshooting. Without regular maintenance, even high-quality equipment can fail due to banal blockage of the tube with food particles.
In this article we will analyze in detail the design of the No Frost and drip defrosting system applicable to models Daewoo. You will learn how to safely reach hard-to-reach places, what tools are needed for the job, and why it is important to be careful when mechanically cleaning plastic elements.
In refrigerators Daewoo, as in most modern models, the moisture removal system is implemented differently depending on the type of chamber. In the refrigerator compartment, where the temperature is usually maintained at around +4°C, moisture settles on the rear wall. This wall periodically cools and heats up, causing condensation to flow down. It is in the lower part of the back panel, often hidden behind a decorative overlay or plastic groove, that a drainage hole is located. Its diameter is usually about one centimeter, which is enough for the free flow of water, but is easily clogged with mucus or crumbs. In some models drainage hole.
Its diameter is usually about one centimeter, which is enough for the free flow of water, but is easily clogged with mucus or crumbs. Some models Daewoo Royal or Daewoo Electronics the entrance to the channel may be shifted to the side or covered with a removable plug. If you do not see an obvious hole in the center of the gutter, carefully inspect its edges.
The system is designed to minimize noise and prevent odors from the drainage system from flowing back into the chamber. However, over time, plaque forms on the walls of the canal, which narrows the passage. The water stops having time to leave and overflows over the edge of the gutter, ending up on the shelf with vegetables.
It is important to understand the difference between structures with a “crying” wall and a complete system No Frost. In the first case, the water is drained by gravity, and the hole is visible visually. In the second case, the moisture is removed by a fan, and the drainage is often hidden deeper inside the case, requiring partial disassembly for access.
⚠️ Attention: Before any manipulations inside the chamber, be sure to disconnect the refrigerator Daewoo from the power supply. Working with electrical appliances in conditions of high humidity and the presence of water is unacceptable.
The situation with the freezer compartment in refrigerators Daewoo with the system No Frost looks different. You won't see an exposed hole here as the entire process is hidden behind the massive back panel. The evaporator, on which frost freezes, is located exactly there, and the melt water flows into a pan located under it. The drainage hole in this case is located under the evaporator and is connected to a tube that goes into the technical compartment.
Access to this unit often requires removing the plastic cover of the rear wall. This action may void the warranty if the seals remain tampered with. Therefore, if your refrigerator is under warranty service, it is better to call a technician to diagnose the condensate drainage system condensate drainage.
If the warranty has already expired and you decide to act on your own, remember the fragility of plastic. At low temperatures it becomes brittle. Carefully unscrew the visible screws and release the fasteners to gain access to the evaporator area. It is there, at the bottom of the metal box, that the entrance to the drainage system is located.
Often the problem lies not in the hole itself, but in the ice plug inside the channel. In a freezer, water freezes faster, and if the defrost thermal cycle is not completed correctly, ice can completely block the drain. In this case, a visual inspection without defrosting may not yield anything.
Why is there no visible hole in the freezer?
In No Frost systems, the drainage is hidden under the evaporator. The water flows down the gutter, heated by the heating element during the defrost cycle, and goes into the tube. If you see ice right on the floor of the freezer, it means the drainage is clogged with ice or water that has not had time to drain.>
To effectively clear the drainage, you will need a minimal set of tools. You should not use sharp metal objects such as a knife or screwdriver, as they can easily damage the thin walls of the plastic tube. A puncture in the tube will result in freon or oil entering the chamber, which will require expensive repairs to the compressor.
The optimal solution is to use soft wire with a melted end, a bottle brush or a special flexible cable. A rubber bulb (enema) or a large syringe without a needle is also useful for flushing the canal with water. To disinfect and dissolve fatty deposits, you can use warm water with the addition of soda or a mild detergent.
- 🧼 Soda solution - perfectly breaks down the fat film and eliminates unpleasant odors that can spread from the drainage.
- 🌡️ A syringe with a volume of 20 ml - allows you to create sufficient jet pressure for pushing blockage without splashing water throughout the chamber.
- 🧶 Soft brush - is necessary for mechanical removal of plaque from the walls of the channel where the water flow does not reach.
The cleaning process begins with visual inspection. If the entrance hole is visible, try to carefully insert the prepared instrument into it. Movements must be translational and rotational. Don't try too hard. If you feel resistance, it means that you have hit a bend in the tube or a seal.
After mechanical cleaning, it is necessary to flush the channel. Fill a syringe or bulb with warm water and sharply inject it into the hole. If the water leaves with a “gurgling” sound and does not return, the system is working properly. If the water stands in a column or flows back, the procedure must be repeated.
☑️ Algorithm for cleaning the drainage
Owners of refrigerators Daewoo should know that the design of the drainage system may vary depending on the specific series. For example, in models with a freshness zone or additional air dampers, the water drainage path may be complicated by additional bends. This makes the system more vulnerable to blockages.
Below is a table that will help organize information about the possible locations of drainage in different types of chambers.
| Chamber type | Hole location | Accessibility | Cleaning frequency |
|---|---|---|---|
| Refrigeration (Drip) | Center of the gutter on the back wall | High (apparently) | Once every 6 months |
| Freezer (No Frost) | Under the evaporator, behind the panel | Low (requires disassembly) | As ice appears |
| Freshness zone | Hidden channel in the bottom of the compartment | Average | Once a year |
Particular attention should be paid to models with water dispensers or ice makers. In such refrigerators Daewoo the drainage system can be double: one part is responsible for condensate from the evaporator, the other for possible leaks from the water supply system. You can usually find the second hole in the lower part of the case, closer to the compressor compartment, but access to it is often limited.
If after cleaning the problem returns after a short time, the angle of the refrigerator may be broken. For proper water drainage, the housing must be slightly tilted backwards. Check the adjustment of the front legs. If the refrigerator is level or tilted forward, water will stagnate in the gutter, even if the drainage is clear.
⚠️ Attention: Never use hot tap water for cleaning. A sudden change in temperature can cause cracks in the plastic gutter or damage the rubber seals of the system. No Frost.
In addition to mechanical cleaning, it is important to maintain the hygienic condition of the refrigerator compartment. Sticky jam stains, bread crumbs and vegetable particles are an ideal breeding ground for bacteria and mold. Once in the drainage hole, this organic matter creates a dense biofilm that is difficult to remove with plain water.
Regular washing of internal surfaces using safe detergents reduces the risk of blockages. Pay special attention to the back wall. Wipe it with a soft sponge, being careful not to damage the fragile surface. If you notice that water flows down the wall slowly, forming streams rather than in a wide veil, this may be a sign that the gutter is beginning to become dirty.
Sometimes the cause of problems is not the channel itself, but the water collection pan located above the compressor. If mold has grown in it or midges have infested, the smell will penetrate into the chamber through the drainage tube. For prevention, it is recommended to pull out the refrigerator once a year and check the condition of the tray, if necessary, washing it with a disinfectant solution.
It is also worth mentioning chemical cleaning agents. There are special tablets and gels for cleaning drains, which can be found in household chemical stores. They effectively dissolve organic deposits. However, before using them, make sure that the composition is safe for food refrigerators and does not contain aggressive chlorine-containing components, the vapors of which can be absorbed by the products.
Despite the apparent simplicity of the design, the moisture removal system in refrigerators Daewoo requires careful attention. Ignoring the first signs of a blockage, such as the whistling sound of water escaping or water standing in the gutter for a long time, can lead to serious consequences. Water that gets onto the electronic control modules or into the case insulation causes corrosion and loss of thermal insulation properties.
In some cases, a blockage may be caused by a manufacturing defect, for example, remnants of polyurethane foam or plastic inside the tube. If you find that the tube is pinched or has a defect in its shape, repairing it yourself may not be possible. In such a situation, you will need to replace the drain tube or the entire rear panel.
Remember that proper operation extends the life of the equipment. Do not pack food into the refrigerator compartment too tightly, blocking air circulation. This leads to the formation of excessive condensation, which the drainage system may not physically cope with, even if it is absolutely clean.
Following simple rules for fridge care Daewoo guarantees its long and trouble-free service. The ability to find and clean the drain hole is a basic skill that every owner of modern household appliances should have. This allows you to quickly respond to malfunctions and maintain an ideal microclimate for storing food.
If you have followed all the recommendations, but water continues to accumulate, or you hear strange gurgling and hissing sounds that do not stop, the problem may be deeper. This may indicate a malfunction of the defrost heating element, timer or thermostat. In such cases, diagnostics require special instruments and knowledge of the electrical circuit.
Why does the water in the drainage hole freeze and form a plug?
This happens if the defrosting cycle does not complete or occurs too rarely. The defrosting heating element may not heat the drainage tray to the required temperature, and the water flowing from the evaporator freezes in the narrowest place - at the entrance to the tube. Also, the reason may be the absence or displacement of insulation on the drainage tube in the freezer.
Is it possible to use mole or other pipe cleaners to clean the drainage?
It is strictly not recommended. Aggressive chemicals intended for sewer pipes can corrode the plastic of the gutters and refrigerator tubes Daewoo. Vapors from such products are toxic and can be absorbed by rubber seals, after which the smell will take a very long time to escape from the chamber. Use only baking soda or specialized mild products.
How to understand that the drainage hole is completely clean?
A sign of a clean system is the rapid drainage of water without delay. If you pour in a glass of water and it disappears with a characteristic suction sound in a couple of seconds, leaving the bottom dry, the drainage is working perfectly. You can also blow into the tube (through a thin tube): the air should flow freely, without resistance.
What to do if an unpleasant odor appears after cleaning?
The smell can come from the pan above the compressor or from the depths of the drain tube, where particles of rotting organic matter remain. Try flushing the system with a solution of citric acid or vinegar (weak), and then with clean water. If the smell remains, you may need to disassemble the back panel of the freezer to sanitize the evaporator.
