Many owners of modern household appliances mistakenly believe that the presence system drip defrosting completely eliminates the need for manual intervention in the operation of the unit. This is a common misconception and can lead to shortened compressor life and poor cooling performance. Although the evaporator in such models does defrost automatically during compressor operation cycles, an ice mass gradually accumulates in the drainage system and on the walls of the chamber.
Ignoring scheduled maintenance leads to drainage hole clogging with dirt and ice, the water stops flowing into a special tray and begins to accumulate at the bottom of the refrigerator compartment or, even worse, leak onto the floor, even if visually it seems that there is no ice inside. This is necessary for hygienic cleaning and restoration of normal air circulation. Full manual defrosting of the drip refrigerator is required at least once a year, even if visually it seems that there is no ice inside. This is necessary for hygienic cleaning and restoration of normal air circulation.
In this article we will analyze in detail the algorithm of actions that will allow you to safely and effectively carry out the defrosting procedure without damaging fragile structural elements. You will learn why you should not use a hair dryer, how to properly wash interior surfaces, and what to do if the water does not go away. Compliance with these rules will help keep energy efficiency your device at a high level.
Why you need to defrost a refrigerator with a drip system
The principle of operation of a drip system, often called Direct Cool or “Crying” wall” implies periodic shutdown of the compressor, during which the frost frozen on the rear wall melts and flows down. It would seem that the process is completely automated. However, in reality, some of the moisture does not have time to evaporate from the drainage tray above the compressor, and some freezes in the outlet channel itself, especially if products with high humidity are stored in the refrigerator.
The growth of an ice crust inside the housing creates an additional thermal load. The compressor has to work longer and harder to maintain the set temperature, which leads to excessive energy consumption and wear on the motor. In addition, in stagnant water in the drainage, bacteria and mold begin to multiply, which can become a source of unpleasant odor.
Regular defrosting allows you to:
- 🧊 Remove hidden ice plugs in the drainage channel, which cannot be removed without complete thawing.
- 🦠 Carry out a deep disinfection of internal surfaces and rubber seals.
- 🔌 Give the compressor a rest and extend the life of the refrigeration unit.
- 💡 Inspect shelves and drawers for cracks, which often form from constant contact with ice.
⚠️ Attention: If you notice, that there is constantly water at the bottom of the refrigerator compartment, this is the first signal that the drainage system is clogged and urgent defrosting and cleaning of the channel is required.
Preparation for the defrosting procedure
Before starting active actions, you must properly prepare the device and clear the space around it. First, remove all food. If it’s winter outside, you can take them out to the balcony (if the temperature there is not lower than +5°C for vegetables and fruits, or below 0°C for freezing, if we are talking about a freezer). In the warm season, it is better to put food in bowls with ice or temporarily place it in a working freezer, if its volume allows.
Disconnect the refrigerator from the power supply. Unplugging the plug is a critical safety rule. Electric current and water are a dangerous combination, so make sure the power cord is not sitting in water or on a wet surface during the process. It is also worth moving the unit away from the wall to provide access to the back and air circulation.
Prepare the necessary equipment in advance so as not to run after it while the ice is melting:
- 🧹 Soft microfiber or cotton rags (do not use fluffy materials).
- 🧼 Detergent (specialized for refrigerators or a weak soda solution).
- 🥣 Containers for collecting water (wide basins or baking sheets).
- 🧽 Sponges with a soft abrasive side for removal contamination.
- 🔦 Flashlight for inspecting hard-to-reach places.
Cover the floor around the refrigerator with floor rags or old towels. Even with careful defrosting, some of the water may leak out, especially if the drainage channel is heavily clogged. Also place a rag inside the refrigerator compartment on the bottom shelf to absorb dripping water if you are afraid of damaging the plastic bottom.
Step-by-step instructions: how to defrost correctly
The safest and most correct way to defrost is natural. Leave the refrigerator doors open and wait. Depending on the amount of ice and the temperature in the room, this process can take from 3 to 10 hours. Do not try to speed up the process using aggressive methods, as sudden temperature changes are dangerous for materials.
It is better to remove internal shelves, drawers for vegetables and removable grilles immediately after disconnecting from the network. It is more convenient to wash them in the bath or under the shower with warm water. While they dry, work on the inner walls. If the ice on the back wall has not yet melted, do not touch it. When it turns into water, wipe the walls with a soft sponge with a cleaning solution.
☑️ Defrosting checklist
Pay special attention drain hole. It is usually located at the bottom of the rear wall of the refrigerator compartment. In normal condition, a small channel is visible there. If it is clogged, carefully clean it with a special brush (often included) or a soft wire wrapped in cotton wool. Do not use sharp metal objects to avoid puncturing the evaporator tube.
After all the ice has melted and the water has been removed, thoroughly wipe all surfaces with a dry cloth. Moisture inside an enclosed space is an ideal environment for mold. Make sure that there are no drops left in the corners and folds of the sealing gum.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers, icebreakers) to chip ice. One careless movement can break through the cooling circuit, after which repairing the refrigerator will become economically unfeasible.
What you absolutely cannot do
There are a number of “folk” methods that may seem effective, but pose a direct threat to the integrity of the refrigerator. The main enemy of plastic and evaporator tubes is high temperature. Many people try to speed up thawing by using a hairdryer, a heater, or placing bowls of boiling water inside.
Using a hairdryer creates local overheating. The plastic of the inner chamber can be deformed by a hot air stream, and sudden temperature changes lead to the appearance of microcracks in the sealed evaporator tubes, which are hidden behind the rear panel. Repairing such a malfunction is difficult and expensive.
List of prohibited actions when defrosting:
- 🔥 Place inside a pan or bowl with boiling water (steam condenses and freezes in other places, and plastic melts).
- 🌬️ Blow hot air from a hair dryer or a construction hair dryer.
- 🔨 Knock off the ice with a knife, hammer or other hard objects.
- 🧪 Use aggressive chemicals, bleach or abrasive powders for cleaning.
- 💧 Pour hot water directly onto ice crust.
What happens if you damage the evaporator?
If you pierce the wall of the evaporator, refrigerant (freon) will begin to hiss out of the hole. This is a gas that is colorless, but may have a specific odor. The refrigerator will stop freezing. It is impossible to weld the hole yourself at home; you need to call a specialist with equipment for vacuuming and filling the system. In addition, some types of freon, when in contact with an open flame (for example, if you smoked nearby) can form toxic compounds.
Table: Comparison of defrosting methods
So that you understand the difference between safe and risky methods, we have compiled a comparison table. It will help you choose the right strategy of behavior depending on your situation.
| Method | Safety | Speed | Risks |
|---|---|---|---|
| Natural thawing | High | Low (4-10 hours) | Absent |
| Fan (cold air) | High | Average | Minimum (noise) |
| Hair dryer (hot air) | Low | High | Plastic deformation, breakdown circuit |
| Mechanical chipping | Critical low | High | Depressurization of the system, loss of freon |
As can be seen from the table, the only method that does not carry risks for expensive equipment is This is natural thawing. The loss of time in this case is the price to pay for long and reliable operation of the equipment. If you urgently need to empty the chamber, it is better to use a fan, directing a flow of room temperature into the open door, but not hot air.
Care after defrosting and startup
After you have thoroughly washed and, most importantly, wiped all surfaces dry, assemble the refrigerator. Place shelves and drawers in place. Before turning on the equipment, make sure that the inside is completely dry, especially in the niche for the light bulb and around the thermostat. Moisture in the electrical contacts can cause a short circuit.
Plug in the refrigerator, but do not load it with food right away. Let it run idle for 1-2 hours. During this time, the unit will reach the required temperature and the compressor will turn off. Only after the first automatic shutdown can you add food. This will prevent the motor from overloading.
Check the operation of the drainage system. Pour some water (about 50 ml) into the groove on the back wall of the refrigerator compartment. The water should flow quickly and without gurgling into the hole. If the water is standing, repeat the procedure for cleaning the channel with a brush.
⚠️ Attention: Specifications and maintenance requirements may vary slightly depending on the model and manufacturer. Always check the official user manual (operation manual) for your specific model Indesit, Bosch, LG or other brand, as the design of the drainage system may have nuances.
Frequently asked questions and answers (FAQ)
How long does it take on average to defrost a drip refrigerator?
Usually the process of complete thawing takes from 4 to 8 hours if the ice crust does not exceed 5-7 mm. If a lot of ice has accumulated, it may take up to 10-12 hours. The exact time depends on the room temperature and the thickness of the ice layer.
Is it possible to wash the inside of the refrigerator with tap water?
Yes, you can, but it is important to use warm water and a soft sponge. The main rule is that after washing, all surfaces must be thoroughly wiped dry. Residual moisture will lead to the rapid formation of new plaque and increase the humidity inside the chambers.
Why does the refrigerator not turn off for a long time after defrosting?
After defrosting, the internal walls and food (if you loaded them right away) are at room temperature. The compressor takes time (sometimes up to 2-3 hours) to cool the entire volume to the specified values. This is normal operation. If the refrigerator does not turn off for more than 5-6 hours, check the tightness of the door.
Is it necessary to lubricate the rubber seal after washing?
Yes, this is a useful procedure. Wipe the rubber door seal with a glycerin solution or a special rubber care product. This will prevent drying out, cracking and maintain elasticity, ensuring a tight fit of the door.
