The appearance of a puddle at the bottom of the refrigerator compartment or, even worse, on the kitchen floor is always an unpleasant surprise that forces the owner of the equipment to look for the cause of the malfunction. In most cases, especially when it comes to models with a drip defrosting system, the problem lies in a banal blockage of the outlet channel, through which the moisture should go into a special pan. Refrigerators Daewoo, known for their reliability and ergonomics, are no exception to this rule, and their design also requires the presence of such a technological hole.
Owners often panic when they notice water and begin to look for complex breakdowns of the compressor or evaporator, forgetting about the simplest element of the condensate removal system. Drainage hole is a small slot or round hole located in the rear inner wall of the refrigerator compartment, which serves as a “drain” for melt water. Understanding where it is located and how it functions will help you quickly fix the problem without calling a technician.
In this article we will examine in detail the anatomy of refrigerators Daewoo, consider the typical causes of blockages and provide step-by-step instructions for safely cleaning the drainage system. You do not need special tools or deep technical knowledge to cope with this task yourself, returning the equipment to its original operating efficiency.
The principle of operation of the drip system in Daewoo
To understand exactly where the water should flow, it is necessary to briefly consider the physics of the refrigeration chamber. In models with drop defrosting (or Low Frost), the rear wall of the chamber is also an evaporator, which is periodically cooled to subzero temperatures. During operation, frost and an ice crust forms on it, which then thaws during a pause in the compressor operation.
The resulting moisture flows down under the influence of gravity down the ribbed surface of the rear wall. It is to collect this water that a special recess is provided in the lower part of the wall, above the shelf for vegetables, in the center of which there is an entrance to the drainage channel. If this path is clear, the water freely goes into the tray above the compressor, where it safely evaporates.
⚠️ Attention: In models with the system No Frost the principle is similar, but the drainage hole is often hidden behind a plastic panel inside the freezer or is located in a hard-to-reach place behind the back wall of the main chamber. An attempt to find it on the visible part of the wall in such models may be unsuccessful.
It is important to note that the efficiency of water removal directly depends on the temperature inside the chamber and the condition of the door seals. If the door does not close tightly, warm air enters the chamber, which leads to the formation of an excessive amount of condensation, which a narrow drainage channel may simply not physically cope with, even if it is completely clean.
Localization of the drainage hole in different models
Finding the place where moisture comes out is the first step to solving the problem. In refrigerators Daewoo of the standard design (two-chamber with one refrigerator compartment door), the drainage hole is located on the rear inner wall, strictly in the center, in its lower part. It is located directly above the niche for storing vegetables and fruits, often under a decorative overlay or in a recess.
Visually, this is a small round or oval hole with a diameter of about 1-2 centimeters. In some modifications, it can be closed with a plastic plug with a slot, which prevents the entry of large pieces of food, but allows water to pass through. If you look into the bottom of the chamber and do not see an obvious hole, carefully inspect the plastic elements - sometimes manufacturers disguise the entrance to the channel with the color of the wall.
- 🔍 Classic models: The hole is visible to the naked eye on the back wall above the drawers.
- 🔍 Models with dispense: The location may be shifted to the side due to internal wiring and channels.
- 🔍 Built-in equipment: The design is identical to the classic one, but access may be difficult due to the dimensions of the niche.
The situation becomes more complicated if you have a model Daewoo with the system No Frost. In such devices, the drainage hole is most often located in the freezer compartment, in the back wall, often hidden behind a plastic cover. Water from the refrigerator compartment is discharged through the internal gutter exactly there. Therefore, if there is water in the No Frost refrigerator, you sometimes have to look for the blockage through the freezer, which requires more complex disassembly.
The main causes of blockages and the appearance of water
Why does the water stop draining? The most common and common cause is the ingress of food particles, crumbs, pieces of polyethylene from food packaging or leaves from herbs into the canal. Even a small lump of mucus, formed from a mixture of dust and fat, can tightly clog a narrow canal, the diameter of which is often less than a centimeter.
The second reason may be freezing of the canal itself. If the refrigerator operates under constant heavy load or the temperature regime is abnormal, the water in the drain tube may freeze, turning into an ice plug. This often happens if the door is used too often or if the defrost sensor is faulty and the water does not have time to drain before the next cooling cycle.
⚠️ Attention: The use of sharp metal objects (knitting needles, knives) for cleaning is strictly prohibited! You can damage the internal cooling circuit or pierce the plastic tube, which will lead to a freon leak and costly repairs.
It is also worth mentioning the displacement of the refrigerator itself. If Daewoo it stands unevenly and has a strong tilt back, water physically cannot flow into the hole, but spreads across the floor of the chamber. The correct angle of inclination is a fundamental requirement for the operation of a gravity drainage system.
Tools and preparation for cleaning
Before taking active steps, it is necessary to properly prepare the workplace and tools. You don't need a complex professional set, just items that can be found in every home. The main thing is to act carefully and follow the sequence so as not to damage the internal elements of the refrigerator.
For work you will need: a soft rag or sponge to collect water, a basin or container for draining, warm water and, in fact, a cleaning tool. For the latter, a special flexible stick brush, which often comes with a refrigerator, or regular knitting wire with a bent and smoothed end is ideal. You can also use a medical bulb (syringe) or a large syringe without a needle for rinsing.
| Tool | Purpose | Safety requirements |
|---|---|---|
| Flexible wire / brush | Mechanical removal of the plug | The ends must be rounded |
| Syringe / Bulb | Washing with water under pressure | Use only warm water |
| Cotton sticks | Final cleaning of the entrance | Do not leave lint inside |
| Vacuum cleaner | Removing softened dirt | Only in blowing mode (with caution) |
Be sure to turn off the power to the refrigerator before starting work. Although the risk of electric shock is minimal when working inside a plastic chamber, safety is paramount. In addition, this will allow you to defrost the ice plug if the cause of the blockage is freezing.
☑️ Preparing for cleaning
Step-by-step instructions for cleaning the drainage
The cleaning process can be divided into several stages. The first step is to remove any visible dirt around the hole. Take a dry cloth or cotton swabs and carefully remove all debris that has accumulated in the recess above the entrance to the canal. This will prevent dirt from being pushed further into the tube.
Next is mechanical cleaning. Take the prepared flexible wire or brush. Carefully, without sudden movements, insert the tool into the hole, moving deeper by 10-15 centimeters. Make rotational and translational movements, trying to crumble or catch the clog. Do not use excessive force so as not to damage the walls of the canal.
What to do if the wire does not pass?
If you feel a hard blockage that cannot be broken through mechanically, do not press harder. Pour 50-100 ml of warm (not hot!) water into the hole and wait 10-15 minutes. Warm water will soften the fatty or food plug, and then try again with the wire.
After mechanical impact, it is necessary to rinse the channel. Fill a syringe or bulb with warm water and sharply inject it into the hole. If you hear gurgling and the water goes away, the system is working. If the water is standing, repeat the procedure. To enhance the effect, you can add a little soda or citric acid, which will help dissolve fatty deposits.
The final stage is verification. Pour a glass of water into the hole and watch how quickly it goes away. The water should drain quickly, without delay. After this, wipe the camera dry and turn on the refrigerator. It is recommended to periodically check the bottom of the chamber in the first couple of hours for the appearance of new moisture.
Prevention and care of the moisture removal system
To prevent the problem with water at the bottom of the refrigerator Daewoo from becoming a regular occurrence, it is important to follow simple operating rules. First of all, watch the packaging of the products. Do not place open bags with crumbling products on the shelves, and store vegetables and fruits in special containers or tightly closed boxes so that particles of earth and leaves do not fall on the back wall.
Regular cleaning inside the refrigerator compartment is the key to a long service life of the drainage system. Wipe the back wall with a damp cloth once a month, paying particular attention to the area around the drainage hole. This will help to detect incipient blockages in time and eliminate them before they become critical.
- 🧼 Carry out a general cleaning of the refrigerator at least once every six months.
- 🧼 Check the integrity of the food packaging before loading.
- 🧼 Make sure that the products do not touch rear cold wall.
It is also important to monitor the operation of the door seals. If the rubber does not fit tightly, a lot of warm air enters the chamber, which sharply increases the amount of condensation. The drainage hole may simply not be able to handle the volume of water, even if it is clean. Regularly check the tightness of the door and, if necessary, adjust it or change the seal.
When specialist help is needed
Despite the fact that Most water problems can be solved by simple cleaning; there are situations where DIY repairs may be ineffective or even dangerous. If, after thorough cleaning and rinsing, water continues to accumulate, the problem may lie deeper - in the freezing of the drain tube inside the case or in a malfunction of the defrost system.
In models No Frost access to the drainage hole often requires partial disassembly of the internal panel of the freezer. If you are not confident in your abilities or are afraid of damaging plastic latches and fragile elements, it is better to entrust this work to professionals. Incorrect assembly may lead to extraneous noise or disruption of air circulation.
⚠️ Attention: If you notice that air is coming out of the hole along with water, or hear strange sounds (gurgling, whistling) when the compressor is operating, this may indicate a leak in the system or a problem with the fan. In such cases, diagnostics by a specialist is required.
Also, the help of a specialist is needed if the drainage tube bursts inside the housing. This can happen when you inaccurately try to clear the blockage with a stiff wire. In this case, the water does not flow into the pan, but inside the thermal insulation or onto the floor, which can lead to failure of the electronics or damage to the floor covering.
Is it possible to use boiling water for cleaning?
It is not recommended to use hot boiling water, since a sharp temperature change can deform the plastic drainage tube or damage the adhesive joints inside cameras. It is better to use warm water at a temperature of 50-60 degrees Celsius. This temperature is enough to melt ice or grease plug, but is safe for plastic.
How often should you clean the drainage hole?
The recommended frequency of preventative cleaning is once every 6 months. However, if you notice that the water drains slower than usual or traces of dirt have appeared around the hole, the procedure should be carried out immediately, without waiting for the scheduled date.
What to do if the water smells?
An unpleasant odor indicates the presence of bacteria and mold in the drainage channel. In this case, after mechanical cleaning, it is recommended to rinse the channel with a solution of chlorhexidine or a weak solution of vinegar. This will disinfect the tube and eliminate the source of the odor.
Why does water flow onto the floor and not into the tray?
This happens if the evaporation tray above the compressor is overfilled (due to high humidity in the room) or if the angle of the refrigerator is broken and water overflows over the edge of the tray. It is also possible that there may be a blockage at the junction of the tube with the tray.
