Modern brand refrigerators Ariston are famous for their reliability and thoughtful design, but even the most advanced equipment requires periodic maintenance. Many owners mistakenly believe that the presence of an automatic moisture removal system completely eliminates the need for manual intervention, but this is not always the case. Understanding the operating principles of your unit will help you avoid unpleasant surprises in the form of puddles on the floor or an unpleasant odor.
The process of removing ice crust directly depends on the type of cooling system installed, be it classic static or advanced technology. No Frost. Ignoring these differences may result in damage to the evaporator or failure of the temperature sensors. In this article, we will analyze in detail the algorithms of action for different models and point out the critical mistakes that users often make when trying to speed up the process.
Regular maintenance not only extends the life of the compressor, but also ensures optimal conditions for storing products. Air circulation channels clogged with ice cause the motor to wear out, trying to compensate for insufficient heat transfer. Timely and competent defrosting is an easy way to save on repairs and electricity.
Determining the type of cooling system in your refrigerator
The first and most important step is to accurately determine the type of system installed in your device. Ariston. The entire further strategy of your actions and the frequency of the maintenance procedure depend on this fundamental parameter. The systems can be visually distinguished by the presence or absence of a visible snow deposit on the back wall of the main chamber.
If you observe freezing of ice on the back panel, which periodically melts and flows into the drainage hole, then you have a classic drip system. In such models, moisture condenses on a cold surface, freezes, and then, during a pause in the compressor, flows into a special groove. This is a natural process that requires periodic complete shutdown of the device for hygienic cleaning.
In models with the system No Frost ("without frost"), ice does not form on the walls at all, since moisture is removed outside the chambers during air circulation. Here the evaporator is hidden and located separately, usually at the top or behind the back panel of the freezer. For such devices, complete defrosting is extremely rarely required, mainly for prevention or in emergency situations.
- ❄️ Drip system: ice freezes on the back wall and periodically thaws on its own.
- 🌬️ No Frost: ice is not visible, air circulates forcibly, the walls are dry.
- 🔧 Combined system: drip in the refrigerator compartment, No Frost in the freezer.
Owners of mechanically controlled devices should pay attention to the temperature regulator. If the knob has marks from 1 to 5 or from Min to Max, this most often indicates a classic operating scheme. Electronic control with a display is more often found in models with full No Frost, although there are exceptions in the lines Ariston.
Preparing an Ariston refrigerator for defrosting
Regardless of the type of system, proper preparation will minimize risks and remove unnecessary fuss. You should start by freeing up the internal space: all products must be removed, sorted and, if possible, transferred to another refrigerator or thermal bag. It is better to wrap frozen prepared foods in the freezer in thick bags or blankets to slow down the melting.
⚠️ Attention: Never leave defrosted foods at room temperature for a long time, especially meat and dairy products, as this can lead to spoilage and bacterial growth.
The next critical step — power outage. Unplug the cord from the outlet or turn off the circuit breaker on the panel. You should not rely on the power button on the case, as some models Ariston can remain energized in standby mode, which is unsafe when carrying out wet cleaning. It is also necessary to turn off the water supply if your model is connected to the water supply for the ice maker.
To collect melt water, prepare the necessary equipment in advance. You will need:
- 🧺 Several large towels or rags to absorb moisture.
- 🪣 Wide containers with low sides for collecting water from the floor.
- 🧽 Sponges and soft rags for washing shelves and walls.
- 🧴 Detergent that does not contain abrasive particles.
☑️ Preparation for defrosting
It is also better to cover the floor next to the refrigerator with rags or newspapers, since water can flow out from under the bottom, especially if the drainage hole is clogged. Some models Ariston are provided with a removable plastic tray for collecting water above the compressor, but its volume is limited, and you should not rely on it alone.
The process of defrosting the refrigerator compartment
In the refrigerator compartment of models Ariston with a drip system, the process occurs quite quickly. After opening the doors and turning off the power, the ice begins to melt under the influence of room temperature. The main task here is to ensure free flow of water into the drainage hole, usually located in the lower part of the back wall.
If you notice that water is standing in the gutter and does not drain, the drainage channel is probably clogged. To clean it, you can use a special flexible brush or a piece of soft wire pre-wrapped in fabric. You must act carefully so as not to pierce the plastic tube that runs inside the housing wall to the evaporator.
How to check the cleanliness of the drain
Pour a small amount of warm (not hot!) water into the drainage hole. If it goes away quickly with a gurgling sound, the channel is clear. If it is, careful cleaning is required.
It is better to remove the shelves and drawers and wash them separately in the bathroom or under the shower. This will open access to hard-to-reach corners of the chamber and allow for high-quality processing of door seals. Rubber cuffs on doors Ariston often collect dirt and mold, which become a source of unpleasant odor, so wipe the folds with a cotton swab dipped in soda solution.
To speed up the process, you can put a container of warm water inside the chamber, but this must be done with caution. Sudden temperature changes are undesirable for plastic and glass shelves. The optimal water temperature for defrosting is about 40-50 degrees Celsius.
Defrosting a No Frost and Low Frost freezer
Freezers in refrigerators Ariston are often equipped with a system No Frost or its equivalent Low Frost. In such units, ice freezes on a hidden evaporator, which is located behind a plastic panel. In normal mode, this ice is periodically thawed by a heating element (heating element), and the water evaporates or flows into the pan.
However, there are situations when the system fails: the drainage channel becomes clogged with an ice plug, the heating element or defrost sensor fails. As a result, the freezer becomes overgrown with a “fur coat” from the inside, the door warps and stops closing tightly. In this case, complete manual defrosting is required for at least 24 hours.
It is strictly forbidden to use sharp objects to chip ice inside the freezer. Thin-walled evaporator tubes in models Ariston are located very close to the surface, and one careless blow with a knife will lead to freon leakage. Repair in this case will be complex and expensive, requiring replacement of shut-off valves and refilling with refrigerant.
| Parameter | Drip system | No Frost system |
|---|---|---|
| Defrost frequency | 1-2 times a year | Only in case of breakdown or once every 3-5 years |
| Presence of ice | On the back wall | Absent (normal) |
| Duration | 4-8 hours | 12-24 hours |
| Manual ice removal | Not required | Prohibited (wait for natural melting) |
If the ice in the freezer has not melted after 24 hours of defrosting, the problem may lie deeper, for example, in a frozen drainage channel inside the cabinet. In such cases, it may be necessary to dismantle the back panel of the freezer to access the evaporator, which is best left to a qualified technician.
Accelerating the process: permitted and prohibited methods
Natural defrosting is the safest, but long way. If time is pressing, you can use aids, but you need to do this wisely. The main rule: no open flame sources or extremely high temperatures. The plastic used in Aristoncan deform when heated above 60 degrees.
One of the effective ways is to use a fan. Direct the flow of room air into the open compartments of the refrigerator. This will increase circulation and significantly speed up the melting of the ice. You can also place several wide containers with hot water inside, changing them as they cool down.
⚠️ Attention: Using a hairdryer is only permissible in cold blowing or barely warm air mode. Directing a stream of hot air at plastic parts or rubber seals is strictly prohibited in order to avoid their melting and loss of elasticity.
There is a myth that defrosting can be accelerated by placing a pan of boiling water inside. This is a dangerous misconception. Steam, condensing on cold walls, can damage the paintwork or cause microcracks in the plastic due to sudden local heating. In addition, boiling water can damage glass shelves.
Never use a knife, screwdriver or ice pick to mechanically remove ice. Even if the layer of ice seems thin, there may be a passage of refrigerant underneath it. Damage to the cooling circuit is a fatal mistake, after which it is easier to throw away the refrigerator than to repair it.
Care after defrosting and starting the equipment
After all the ice has melted and the water has been removed, you must thoroughly wipe all surfaces dry. Moisture is the enemy of electrical appliances, so make sure there are no puddles left in the drainage hole or at the bottom of the chamber. Let the refrigerator stand with the doors open for another 30-40 minutes to dry completely.
Now you can wipe the internal surfaces with a weak solution of vinegar or a special product for cleaning refrigerators. This will disinfect the camera and eliminate any possible odors. Pay special attention to the seals: they can be treated with glycerin or silicone grease so that the rubber does not dry out and the door closes hermetically.
Include The refrigerator can only be plugged in after it has completely dried. First, connect the empty unit to the network and let it run for 1-2 hours without loading. This will allow you to reach operating temperature and ensure that the thermostat is working properly. Only after the refrigerator “gets cold” can you load food.
Regular monitoring of the condition of the drainage system and the cleanliness of the condenser (grid at the back or bottom) will help avoid frequent defrosting. If the refrigerator is located close to the wall, move it away to ensure proper ventilation of the compressor. Overheating of the rear part often leads to malfunctions of the automatic defrost.
Frequent errors and possible problems
Even knowing the theory, users often make mistakes that nullify all efforts. One of the most common is turning on the refrigerator Ariston immediately after defrosting with a full load of warm food. The compressor is forced to work without interruption, trying to cool a large volume, which can lead to its overheating and breakdown.
Another mistake is ignoring the installation level. If the refrigerator is not level, water from the drain may not flow into the hole, but flow out or stagnate inside, causing corrosion and odor. Check the legs and, if necessary, twist them to a strictly horizontal position with a slight tilt back.
- 🚫 Using aggressive chemicals (chlorine, acetone) to wash plastic.
- 🚫 Loading products until the temperature reaches temperature.
- 🚫 Ignoring the sounds of gurgling or humming sound after turning on (this is normal, but requires checking).
If after defrosting the refrigerator does not freeze or freezes too much, there may be air left in the system or an electronics failure. Electronically controlled models may require a factory reset. To do this, you usually need to hold down a certain combination of buttons specified in the instructions for your specific model.
Remember that technical specifications and control interfaces may vary depending on the year of manufacture and series. If you are not sure of the actions, it is better to check the official documentation or consult with a specialist, especially when it comes to complex electronic control systems.
Is it necessary to defrost the Ariston No Frost refrigerator?
In normal mode - no. The No Frost system automatically removes moisture. Defrosting is required only in case of breakdown (ice has frozen), odor appears, or for general cleaning once every 1-2 years.
How long should a refrigerator defrost?
For a refrigerator compartment, 3-5 hours is enough. A No Frost freezer, when completely defrosted, can take from 12 to 24 hours, depending on the thickness of the ice crust.
Can you use a hair dryer for defrosting?
You can, but only in warm (not hot!) air mode and at a safe distance from the plastic. You cannot keep the hairdryer constantly at one point; you need to constantly move the nozzle.
Why did the smell appear after defrosting?
Most likely, there was water left in the drainage hole or under the casing, in which bacteria multiplied. The drainage needs to be flushed again with a solution of soda or vinegar and completely dried.
What to do if the refrigerator does not turn on after defrosting?
Check the socket and the integrity of the cord. If the power supply is fine, the compressor protection may have tripped or the thermostat may have failed. Let the equipment stand unplugged for a couple more hours. If it doesn’t help, call a specialist.
