Refrigerators brands Liebherr are famous for their reliability and advanced technologies, but even the most advanced equipment requires regular and competent maintenance. Many owners mistakenly believe that the presence of the system NoFrost completely eliminates the need to defrost the unit, but this is not entirely true. Although ice does not form in the main chamber, static electricity, dust and bacteria can accumulate on the evaporator, reducing the efficiency of the compressor.
Proper defrosting is not just removing ice, but a complex procedure that includes cleaning internal channels and disinfection. Ignoring this process can lead to the appearance of an unpleasant odor, deterioration in the quality of food storage and, ultimately, to the breakdown of expensive components. In this article we will analyze in detail the algorithm of actions that will help you safely service your Liebherr.
It is worth noting that the frequency of the procedure depends on the intensity of use and operating conditions. If you notice that the refrigerator has become louder or is taking longer to rise in temperature, this is a sure signal that it’s time to start defrosting it. Regularity is a key factor in the long service life of the equipment.
Preparation for the defrosting procedure
Before starting active actions, it is necessary to carry out a number of preparatory measures. This will ensure the safety of the process and the safety of your products. First of all, empty the refrigerator and freezer compartments of their contents. It is better to put the products in bowls with ice or temporarily place them in another cold place so that they do not have time to defrost.
The second important stage is turning off the power supply. Unplug the plug from the socket or turn off the circuit breaker on the panel. Strictly prohibited leave the device on during defrosting, as this will lead to continuous operation of the compressor in vain and may cause it to overheat. In addition, working with an electrical appliance in conditions of high humidity creates a risk of electric shock.
After turning off the equipment, prepare a place to collect water. You will need large towels to place in front of the refrigerator doors and several containers with low sides. The water will drain by gravity, and it is important to prevent it from getting onto the laminate or parquet flooring, as moisture can damage the flooring.
⚠️ Attention: Do not try to speed up the defrosting process by using a hairdryer, heater or hot water. A sudden temperature change can lead to cracking of plastic panels and damage to the evaporator tubes, which will lead to refrigerant leakage.
Disabling the NoFrost system and operating modes
Modern models Liebherr equipped with electronic control, and before defrosting it is important to complete their operation correctly. If your model has a display, you need to make sure that all active modes, such as SuperFrost or SuperCoolare disabled. These modes force the compressor to work at its limit, and their forced interruption without a pause is undesirable.
For models with mechanical control, simply turn the temperature regulator to the “0” or “Off” position before removing the plug from the network. In electronic models with a panel TouchControl or SmartDevice it is recommended to give the device a few minutes of rest after switching off so that the electronics complete the current cycles.
What is SmartFrost in Liebherr?
SmartFrost is a technology in which the evaporator is built into the walls freezer compartment, rather than hidden behind a plastic panel. This makes defrosting easier, since ice accumulates on the walls, which are easy to clean, and does not require disassembling complex structures.">
Particular attention should be paid to models of the series SmartFrost. In them, the evaporator is located around the perimeter of the chamber, which makes cleaning easier, but requires care when cleaning the walls. Do not use sharp objects to chip ice, even if it seems thin. Damage to the coating evaporator in such models often leads to the impossibility of further restoration without replacing the entire chamber.
If your refrigerator is connected to the system Smart Home via Wi-Fi, do not forget to disable remote monitoring or simply ignore error notifications that may come to your smartphone while the equipment is idle.
Process. natural defrosting and collecting water
The safest method recommended by the manufacturer is natural defrosting. Leave the doors of the refrigerator and freezer open. To fix the doors in the open position, you can use small wedges or ask someone from the household to hold them so that they do not slam shut accidentally. The process may take from 3 to 10 hours, depending on the amount of ice and the temperature in the room. room.
Water will flow through special grooves into the drainage hole. In refrigerators Liebherr the drainage system is usually located in the lower part of the rear wall of the refrigerator compartment. It is important to ensure that this channel is not clogged with food debris or debris. If water remains in the chamber and does not drain, the drainage may be clogged. data-i="82">☑️ Preparation checklist

To speed up the drainage of water, you can gently wipe the walls with a soft sponge, but without pressing. Periodically change the towels on the floor and empty the water containers. Hygiene in the defrosting process, it is as important as the technology itself.
⚠️ Attention: Water draining from the refrigerator may contain bacteria and food particles. Avoid contact of this liquid with exposed skin and wash your hands thoroughly after completing work.
Cleaning the drainage system and internal channels
One of the main reasons for the ineffective operation of the refrigerator is a clogged drainage hole. During the defrosting process, you have a unique opportunity to clean this unit. Find the hole in the bottom of the rear wall of the refrigerator. Carefully remove visible debris with tweezers or a soft cloth.
For deep cleaning, you can use a special brush or a twisted brush. burn a soft rag. Push it into the channel with progressive movements. Do not use metal wires, as they can pierce the tube hidden behind the plastic, which will lead to serious damage.
After mechanical cleaning, it is recommended to rinse the drain with warm water and watch how it goes into the pan of the compressor compartment (located at the back). refrigerator, below). If the water is standing, repeat the cleaning procedure. Free outflow Condensation is critical for the proper operation of the NoFrost system.
It is also worth checking and cleaning the rubber seal on the doors. Dirt and mold often accumulate in the folds of the seal, which can occur. prevent the door from sealing tightly. Wipe the seal with a soft cloth soaked in a weak solution of vinegar or a special rubber care product.
Disinfection and elimination of odors
After all the ice has melted and the water has been removed, the disinfection stage begins. Even if there is no visible contamination, there may be colonies of bacteria inside the chamber. cause spoilage of products. To wash internal surfaces, use warm water with the addition of a mild detergent or baking soda solution.
Avoid using aggressive chemicals, abrasive powders and chlorine-containing substances. They can damage the plastic coating of the chambers and leave a persistent chemical odor, which will subsequently be absorbed into the products. Liebherr recommends the use of special care products. refrigerators or a regular soap solution.
Pay special attention to the shelves and drawers. It is better to remove them and wash them separately under running water. Dry all the elements thoroughly before putting them back. The humidity inside a closed refrigerator promotes the growth of mold, therefore dryness is a prerequisite before turning it on.
If an unpleasant odor persists in the refrigerator, check the condition of the activated carbon filter (if provided by the model). Liebherr The filter is located in the upper part of the refrigerator compartment. It must be replaced regularly, according to the instructions, usually once every 6-12 months.
Drying time and first start-up
After completing washing and disinfection, leave the refrigerator open for at least 1-2 hours to dry completely. This is necessary to evaporate moisture from hard-to-reach places and channels. Turning on a wet appliance can lead to a short circuit or the formation of ice jams in the air circulation system.
When you are sure that it is dry inside, assemble the refrigerator: put shelves, drawers and containers in their places. Make sure all fasteners snap into place correctly. Close the doors and only then connect the device to the power supply.
It is better to perform the first start without load. Allow the refrigerator to run empty for 2-4 hours to allow it to reach the required temperature. Indicators on the control panel will indicate when the operating mode has stabilized. Only after this can the products be loaded.
