Modern refrigerators Beko, even equipped with a system No Frost, sometimes require complete disconnection from the network for general cleaning or in the event of a technical failure of the defrost sensors. Many owners mistakenly believe that the presence of an automatic moisture removal system completely eliminates the need for manual intervention, however, hygiene standards and the specific operation of electronics dictate their own rules. Periodic defrosting is necessary to eliminate unpleasant odors, remove bacteria and check the condition of seals.
This process cannot be rushed and requires compliance with certain technical regulations so as not to damage the fragile cooling system. If you notice that a “coat” of ice has formed on the walls of the chamber, despite the declared automatic defrosting function, this is a signal that you need to check the operation of the unit or simply carry out scheduled maintenance. A correctly carried out procedure will extend the service life compressor and maintain the efficiency of the heat exchanger.
In this article we will analyze in detail the algorithm of actions for models with a drip system and technology No Frost, since the approaches to them are radically different. Ignoring safety rules can lead to failure of expensive components or deformation of plastic housing elements. Be attentive to the details described below in order to complete the work efficiently and safely.
Preparing the refrigerator for defrosting
Before starting any manipulations, it is necessary to prepare the workspace and empty the chambers of the contents. The first step is to completely disconnect the device from the electrical outlet, which is a critical safety requirement. You cannot simply pull out the cord if the plug is in a hard-to-reach place - it is better to first move the unit away, providing access to the rear wall.
After turning off the power, all food products should be removed. If you do not plan to use them in the near future, take care of the safety of frozen stocks by placing them in thermal containers or wrapping them in blankets. To store perishable foods during the defrosting period, you can use temporary sources of cold, but this is only relevant during a long process.
⚠️ Attention: It is strictly forbidden to turn on the refrigerator immediately after defrosting is completed. The compressor needs time to warm up the oil and stabilize the pressure in the system, otherwise water hammer may occur.
Next, it is necessary to clear the internal space of all removable elements. Shelves, drawers, egg trays and baskets should be removed and washed separately in warm water using a mild detergent. This will not only clean the chamber itself, but also check the integrity of the plastic parts, which become fragile in the cold.
Pay special attention to preparing the floor around the refrigerator. As the ice melts, a significant amount of water is formed, which can damage the floor covering or flow to the neighbors below. Lay old towels, rags around the device in advance, or prepare flat containers to collect moisture.
Defrosting refrigerators with the No Frost system
Owners of models Beko with technology No Frost are often surprised to learn that their appliances also sometimes need to be defrosted manually. Although the system automatically removes condensate, ice may form in the drain hole or on the evaporator due to blockages or a malfunction of the defrost heating element. In such cases, complete defrosting is required to restore air circulation.
The process for such models takes less time, usually about 2-4 hours, since the main volume of ice is concentrated inside the technical channel, and not on the visible walls. Leave the doors open after turning off the power. Do not try to speed up the process by heating, as a sudden temperature change can damage the plastic evaporator box, which is located behind the rear panel.
If you are faced with a situation where the ice does not melt even after a long period of inactivity, this may indicate a breakdown of the sensor or heating element. In normal mode, after defrosting and turning on, the system should independently drain water through the drainage. If there is water inside the chamber, check the drainage hole for blockages.
Why does ice freeze in No Frost?
Ice in the No Frost system is formed when one of three components malfunctions: the defrost heating element, the timer or the defrost sensor. The reason may also be a loose fit of the door, which allows warm, moist air to enter the chamber, which instantly crystallizes on the cold evaporator.
It is important to understand the difference between planned hygienic defrosting and emergency defrosting. In the first case, you act according to the schedule, in the second, you react to a decrease in freezing performance. For models Beko s Full No Frost it is recommended to carry out the procedure at least once a year to disinfect air ducts.
Drip system defrosting technology
Refrigerator models Bekoequipped drip system defrosting (or “crying evaporator”) require a more thorough and lengthy approach. In such devices, the back wall of the main chamber is periodically covered with frost, which then melts and flows into the drainage. The freezer compartment in such models often requires manual defrosting, since automation there may be absent or work less efficiently.
The waiting time for the ice to completely melt in drip systems can take from 8 to 24 hours, depending on the thickness of the ice shell. It is strictly forbidden to speed up this process mechanically (picking with a knife), since there is a high risk of breaking through the thin-walled cooling circuit filled with refrigerant. Repair in this case will not be economically feasible.
To effectively remove ice, it is recommended to use the natural melting method with the doors open. You can place bowls of hot water inside the chamber, closing the door for 10-15 minutes so that the steam softens the ice, but this must be done carefully so as not to melt the plastic. After each such cycle, water must be removed.
| Parameter | No Frost system | Drip system | Combined |
|---|---|---|---|
| Defrost frequency | 1 time per year (hygiene) | 1-2 times a year | 1 time a year |
| Process duration | 2-4 hours | 12-24 hours | 6-12 hours |
| The presence of ice is normal | Absent | A thin layer is acceptable | Only in the freezer |
| Risk of damage | Low | High (with mechanics) | Medium |
After all the ice has melted, you must thoroughly wipe all surfaces dry. Pay special attention to recesses and places where shelves are attached where water could accumulate. A humid environment is an ideal place for mold to grow, so dryness before turning on is a must.
☑️ Check before turning on
Accelerating the process and safe methods
Natural defrosting is the safest, but long way. If time is running out, you can use auxiliary means that will not harm the equipment Beko. One effective method is to use a fan. Direct the flow of room air inside the open freezer - this will significantly increase circulation and speed up the melting of ice without using high temperatures.
Using a spray bottle with warm (not hot!) water is also allowed. Spray the ice formations, allowing the water to drain. This method helps soften the dense ice crust. However, make sure that water does not get on the electrical contacts, the light bulb or inside the technical holes on the back wall.
⚠️ Attention: Never use a hair dryer, steam generator or heater to speed up defrosting. Local overheating of the plastic can lead to its deformation, and moisture getting on hot electronics will cause a short circuit.
There is a myth that you can put a heating pad with boiling water inside. This is only permissible if the heating pad is located at the bottom of the chamber in the container, and the steam does not directly affect the upper plastic shelves. Direct contact of boiling water with the shelves can cause them to crack due to thermal shock.
If you decide to use a soft rag soaked in warm water to wipe the walls, do it carefully. The fabric should not be too wet so that excess water does not flow into the insulating layer of the housing. It is better to wipe the walls with a dry cloth, removing the already thawed layer by layer.
Caring for seals and cleaning the drainage
The defrosting period is the ideal time for maintenance sealing rubber bands. It is their condition that determines the tightness of the chamber and, as a consequence, the frequency of ice formation. During the washing process, wipe the rubber bands with a soft sponge and soapy water, removing all dirt and food debris that may have gotten into the folds.
After cleaning, it is recommended to treat the rubber with a special silicone grease or regular glycerin. This will restore its elasticity and prevent drying out and cracking. If the seal has lost its shape and does not fit tightly, you can try heating it with a hair dryer (at a safe distance) and straightening it by pressing the door for a while.
Do not forget to clean the drainage hole, usually located on the back wall of the refrigerator compartment or at the bottom of the freezer (depending on the model Beko). To do this, you can use a special brush-brush included in the kit, or a soft wire wrapped in cotton wool. Clogged drainage is a common cause of puddles under the refrigerator.
Check the condition of the condensate tray, which is located above the compressor at the rear of the unit. Water flows into it during automatic defrosting. If the tray is misaligned or dirty, water may leak onto the floor. Rinse it and install it level to ensure proper evaporation of moisture.
Completion of the procedure and first launch
When all internal surfaces have been washed and, most importantly, thoroughly dried, you can begin assembly. Replace all shelves, drawers and containers. Make sure that they fit into their guides correctly and that nothing is preventing the doors from closing freely. Check that nothing is pinching the sealing rubber.
Now the refrigerator can be connected to the network. Please note that it is not recommended to download products immediately. Let the unit run idle for 1-2 hours so that it reaches operating temperature and stabilizes the compressor operating mode. Only after this can you add food.
⚠️ Attention: Do not fill the freezer with warm food immediately after turning it on. This will create an excess load on the compressor and lead to repeated, more intense ice formation.
During the first hours of operation, listen to the sounds made by the refrigerator Beko. A quiet hum from the compressor and occasional gurgling of the refrigerant is considered normal. If you hear a loud knocking, grinding or whistling sound, immediately turn off the device and contact a service center, as this may indicate problems that have arisen during operation or maintenance.
Regular adherence to these simple rules will allow your refrigerator to serve for many years without loss of efficiency. Cleanliness inside the chamber is not only a matter of hygiene, but also a guarantee of economical energy consumption, since a thick layer of ice acts as a heat insulator, causing the motor to work harder.
Frequently asked questions (FAQ)
How long should you keep the refrigerator turned off after defrosting?
After you have washed the refrigerator and wiped it dry, you need to wait at least 3-4 hours before plugging it in. This time is needed for the refrigerant (freon) and compressor oil to warm up to room temperature and distribute throughout the system. Turning on a cold compressor can lead to its breakdown.
Is it possible to defrost a Beko freezer with a hair dryer?
The use of a hair dryer is not recommended by manufacturers. A hot stream of air can unevenly heat the plastic, causing it to deform or cause microcracks. In addition, there is a risk of moisture from the air or condensation getting into the electrical contacts, which will lead to a short circuit. It is better to use a fan with cold air.
What to do if after defrosting the refrigerator does not freeze?
If after defrosting and turning on for 2-3 hours the temperature does not drop, check whether the door closes tightly. If the seal is OK, there may be an air lock in the system or an electronic failure. Try turning off the device for 15-20 minutes and turning it on again. If the problem persists, you need to call a technician.
Is it necessary to defrost a No Frost refrigerator if there is no ice?
Yes, it is recommended to carry out hygienic defrosting and washing at least once a year, even if there is no visible ice. This is necessary to remove bacteria, mold and odors that accumulate on the walls and in the air ducts. In addition, this allows you to check the condition of the seals and the cleanliness of the drainage system.
