Owners of Ariston equipment are often faced with the need for complete defrosting, even if the model is equipped with an automatic moisture removal system. The formation of an ice crust in the freezer is a natural process for a static cooling system, but also in units with No Frost periodically requires general cleaning. Ignoring ice build-up leads to increased energy consumption and reduced compressor efficiency.
Modern refrigerators Ariston are designed with ease of service in mind, but incorrect actions when removing ice can damage the circuit or damage the electronics. In this article we will analyze all stages of the procedure, from preparation to startup, paying special attention to the nuances of working with various types of cooling systems.
High-quality maintenance extends the life of the device. It is important to understand that the rate of ice formation depends not only on the serviceability of the equipment, but also on operating conditions: humidity in the room and frequency of door opening. The correct approach to the issue will avoid emergency situations and keep food fresh.
⚠️ Attention: It is strictly forbidden to use sharp metal objects (knives, screwdrivers) to chip ice. Damage to the evaporator will lead to freon leakage and expensive repairs that cannot be done by yourself.
Features of cooling systems in Ariston refrigerators
Before starting the procedure, you need to determine the type of cooling system of your device. The equipment Ariston can be equipped with a classic drip system (Direct Cool) or modern technology No Frost. In models with a drip system, moisture settles on the back wall, freezes and periodically thaws when the thermostat operates, flowing into the drainage tray. Here, ice formation occurs more intensely.
Models marked No Frost (or Frost Free) operate on the principle of forced air circulation. They have a special heating element built into them, which is periodically turned on to defrost the evaporator hidden behind a plastic panel. Despite the name “frost-free”, such refrigerators also require manual defrosting 1-2 times a year for hygiene and cleaning of drainage channels, which can become clogged with dust and food debris.
The difference in approaches to maintenance lies in the frequency and duration of the process. For classic models, the procedure can take up to 24 hours with a thick ice crust, while for systems No Frost 3-5 hours are enough to completely warm up and dry the internal cavities. Understanding the operating principle of your unit will help you choose the optimal cleaning strategy.
Preparatory stage before defrosting
The process should begin with proper preparation. First of all, it is necessary to empty the refrigerator and freezer compartments of all products. Frozen processed foods, meats and vegetables should be moved to another cold place or wrapped in blankets to slow down the melting. Remove all removable elements: shelves, drawers, egg trays and baskets.
Next, turn off the power supply. Unplug the cord from the outlet or move the toggle switch to the “Off” position, if provided by the design. Do not leave the refrigerator plugged in while defrosting, as this will create a risk of short circuit if water gets on the contacts and will interfere with the natural melting of ice.
Prepare a place to collect water. Cover the floor around the refrigerator with absorbent rags or towels. Place several rags inside the freezer to absorb the first melt water. Prepare a basin or wide container in advance to drain water from the drainage hole, if the model requires it.
☑️ Preparing for defrosting
Natural defrosting: step-by-step algorithm
The safest and recommended by the manufacturer Ariston method is natural thawing. Once you have emptied the compartments and turned off the power, leave the freezer and refrigerator doors completely open. Air circulation will speed up the process of ice melting without the use of aggressive methods.
During the thawing process, water will flow into a special gutter at the bottom of the chamber and then into the drainage hole. It is important to ensure that this drain is not blocked by pieces of ice or debris. If you see that there is water standing in the tray, carefully remove the plug with a soft rag or rubber bulb, but do not push it with hard objects.
Periodically wipe the surfaces freed from ice with a soft rag. This will help remove ice residue faster and prepare the surface for washing. Do not try to speed up the process by opening windows in winter or pointing a fan - sudden temperature changes can negatively affect plastic and rubber seals.
Can you use a hair dryer to speed it up?
Use of a hair dryer is permissible only as a last resort and with great caution. The hot air flow should be directed strictly at the ice, and not at plastic parts or rubber seals, which can be deformed from high temperature. It is better to use a hairdryer at minimum power and keep it at a distance of at least 30 cm from the surface.*/>
Accelerated methods and precautions
If time is running out, you can use accelerated defrosting methods, but this must be done with extreme caution. One way is to place containers of hot water (not boiling water!) inside the chambers. Close the doors for 10-15 minutes, then repeat the procedure. The steam will speed up the melting of the ice. Make sure that the containers are stable and will not tip over.
Another method is to use a fan directed into the open compartment of the refrigerator. This will create forced circulation of warm room air, which will reduce the defrosting time by half compared to natural defrosting. However, make sure that large quantities of dust do not get into the device.
Under no circumstances pour hot water directly onto the ice or chamber walls. A sudden temperature shock can cause microcracks in the plastic or even damage the metal housing of the evaporator. It is also prohibited to use chemical reagents to chip ice, as they can be toxic and dangerous for contact with food.
⚠️ Attention: The use of chemical defrosting sprays is only permissible if they are certified for food equipment. After using such products, you must thoroughly rinse the chamber with water and soda and ventilate it to prevent chemicals from getting into the products.
Cleaning and care after thawing
After all the ice has melted and the water has been removed, you must thoroughly wash the internal surfaces. To wash plastic and metal, use a weak solution of baking soda (1 tablespoon per 1 liter of water) or a special refrigerator cleaner. Avoid using abrasive powders and hard sponges, which can scratch surfaces.
Pay special attention to the drainage hole. It can be carefully cleaned with a special brush or cotton swab dipped in warm water. Make sure that water flows freely into the receiver located above the compressor (at the back of the refrigerator). Clean drainage is the key to the absence of unpleasant odors and mold in the future.
Rubber seals on the doors also require maintenance. Wipe them with a damp cloth, removing crumbs and deposits. To prevent the rubber from drying out and maintaining its elasticity, you can lubricate it with silicone grease or glycerin after it has completely dried. This will extend the life of the seals and ensure a tight fit of the door.
Drying time and first start-up
The most common mistake is turning on the refrigerator immediately after washing. Moisture remaining in hard-to-reach places, in electrical contacts or under casing, can cause short circuits or corrosion. Allow the unit to dry completely while open for at least 2-4 hours, or better yet, leave it overnight.
Before turning it on, make sure that all removable elements (shelves, drawers) are completely dry and in place. Check that nothing interferes with the free movement of the doors. Only after this can you connect the device to the mains.
After turning on, do not load products immediately. Let the refrigerator run idle for 1-2 hours until it reaches the desired temperature. The fact that the mode has been reached is usually signaled by a lit indicator or a characteristic click of the compressor turning off. Loading warm products into an unheated chamber will cause the motor to wear out.

Typical errors and possible problems
Often users try pick out the ice with a knife, which leads to breakdowns of the evaporator. If you hear hissing and smell chemicals (freon coming out), immediately open the windows, leave the room and call a technician. It is impossible to solder the tube and refuel the system without equipment.
Another mistake is turning on the equipment with residual water in the tray or at the bottom. This can lead to the formation of an ice plug in the drainage within the first hours of operation, which will disrupt air circulation. Always wipe all surfaces dry with paper towels before final drying.
If, after defrosting and turning on, the refrigerator does not freeze, but the compressor is running, there may be moisture in the system or a failure in the electronic control module. In such cases, try unplugging the device for 15-20 minutes to reboot the controller. If the problem persists, diagnostics by a specialist is required.
⚠️ Attention: If, after defrosting, the refrigerator makes unusual sounds (gurgling, loud hum) or does not turn off for a long time, this may indicate a leak in the system or a refrigerant leak. Operation in this mode is prohibited.
Prevention of the formation of ice crust
To minimize the frequency of defrosts, monitor the condition of the door seals. If the rubber does not fit tightly, warm, moist air constantly enters the chamber, which instantly condenses and freezes. The test can be carried out using a sheet of paper: hold it with the door and try to pull it out - it should be pulled out with force along the entire perimeter.
Do not put hot or warm foods in the refrigerator. The evaporation of moisture from them sharply increases the humidity inside the chamber, which leads to the accelerated formation of a “fur coat” on the walls. Cool food to room temperature before storing.
Regularly check the temperature in the chambers using a thermometer. A set temperature that is too low (below -18...-20°C in the freezer) unnecessarily also contributes to active ice formation and excessive energy consumption. The optimal mode allows the equipment to work efficiently without excessive load.
How often do you need to defrost an Ariston No Frost refrigerator?
No Frost technology involves automatic defrosting of the evaporator, so you rarely need to remove ice manually. It is recommended to carry out general cleaning and defrosting 1-2 times a year to maintain hygiene, remove odors and check the operation of the drainage system.
What to do if the refrigerator does not turn on after defrosting?
Check the presence of voltage in the outlet and the integrity of the power cord. Make sure the device is completely dry. If there are no visible problems, but the equipment does not respond, the thermostat or control module may have burned out - you need to call a technician.
Is it possible to defrost a freezer with a hair dryer?
You can use a hair dryer with great care. Direct warm air only at the ice, avoiding plastic parts that may become deformed and rubber seals. Do not use the maximum heating temperature.
Why did an unpleasant odor appear after defrosting?
The odor may remain from stagnant water in the drainage channel or from products that were previously stored. It is necessary to rinse the chamber again with a solution of soda or citric acid, clean the drainage and ventilate the refrigerator with the doors open for 24 hours.
