Many owners of modern household appliances mistakenly believe that the system No Frost completely frees them from the need to ever turn off the unit from the network. However, even the most advanced models of the Italian brand Hotpoint Ariston require periodic maintenance, including complete defrosting. This is necessary not only for the hygienic treatment of the internal chambers, but also to extend the life of the compressor and fans.
Two-chamber models with automatic defrosting of the evaporator still accumulate ice crust in hard-to-reach places, which the system cannot remove on its own. Ignoring this process may lead to poor cooling of products and the appearance of extraneous noise during operation of the unit. In this article, we will analyze in detail the algorithm of actions that will help to carry out the procedure safely.
Unlike older models with a drip system, it is important to be careful when working with plastic elements and electronics. Incorrect actions can damage the sensors or break the tightness of the seals. The full defrosting cycle for two-chamber Hotpoint Ariston models takes from 10 to 24 hours, depending on the ambient temperature. Let's look at each stage in detail.
⚠️ Attention: Before starting any manipulations Make sure the power cord is unplugged from the outlet. Working with electrical appliances requires compliance with basic electrical safety rules.
Why it is necessary to defrost the No Frost system
The system No Frost (literally “without frost”) works on the principle of forced air circulation. The fan drives air masses through the evaporator, where they are cooled, and then distributes them among the chambers. Although the main evaporator is located in a hidden niche and defrosts automatically, ice still forms in the main chamber and freezer. This is due to the fact that moisture from food settles on walls and in corners where the air flow does not reach with sufficient intensity.
Over time, the layer of ice can become so thick that it begins to interfere with the operation of the dampers or block the ventilation openings. In models Hotpoint Ariston with two chambers this is especially critical, since disruption of air circulation in one zone affects the temperature regime in the entire unit. Regular defrosting allows you to eliminate this deposit and restore effective heat exchange.
In addition, the hygienic aspect cannot be discounted. Over time, bacteria and mold accumulate on the walls of the refrigerator, which are not destroyed by low temperatures. Periodic washing of defrosting chambers is the only way to ensure sanitary safety stored products. If you neglect this, an unpleasant odor may appear in the refrigerator, which is very difficult to remove with conventional air fresheners.
- ❄️ Removing hidden plaque that blocks ventilation ducts.
- 🦠 Destruction of bacteria and mold on walls and seals.
- ⚡ Reducing the load on the compressor by improving heat transfer.
- 🍏 Preserving the freshness of products and the absence of foreign odors.
It is also worth noting that manufacturers recommend carrying out this procedure at least once a year. For families with a large amount of food or in conditions of high indoor humidity, the frequency can be increased to twice a year. This is especially true for models with a bottom freezer, where the risk of an “ice plug” forming in the drainage is higher.
Preparation for the defrosting procedure
Before you start defrosting a two-chamber refrigerator Hotpoint Aristonit is necessary to carry out a number of preparatory work. This will minimize stress on equipment and keep food fresh. First of all, empty the cameras of their contents. All products, especially frozen ones, should be removed and transferred to another cold place or covered with thermal blankets.
Next, you need to disconnect the device from the power supply. Simply unplugging the cord from the outlet is not enough; if you have a complex Smart Home system or stabilizer installed, make sure that the circuit is completely broken. Then open all refrigerator and freezer doors to allow air to enter. This will start the natural process of ice melting.
It is important to prepare a place to collect water. Although the No Frost system often drains water into the drain pan, if there is excessive melting it can overflow and spill onto the floor. Cover the floor around the refrigerator with rags or place flat containers. You will also need soft sponges and neutral detergents for subsequent cleaning.
☑️ Checklist for preparing for defrosting
Do not try to speed up the process by using a hairdryer or heater directed into the chambers. Sudden temperature changes can lead to plastic deformation or damage to the evaporator tubes. The models Hotpoint Ariston use thin aluminum elements that are easily damaged mechanically or thermally. It is better to spend more time, but keep the equipment intact.
⚠️ Attention: Never use sharp objects (knives, screwdrivers, scrapers) to chip ice. Damage to the evaporator will lead to a refrigerant leak and costly repairs.
Step-by-step instructions for defrosting
The process of defrosting a two-chamber refrigerator Hotpoint Ariston with the No Frost system requires patience. After you have turned off the device and opened the doors, the main stage begins. The ice will begin to melt naturally. Depending on the thickness of the ice and the room temperature, this may take from 3 to 10 hours.
During the process, you will need to periodically check the drain pan, usually located above the compressor at the lower rear of the unit. If water leaks out of the drain hole, make sure it is not clogged with food or debris. In some models, access to the drainage is provided by removing the bottom panel.
After all visible ice has melted, you must thoroughly wipe all surfaces. Use a soft cloth dampened with warm water and mild detergent. Pay special attention to corners, panel joints and rubber door seals. This is where dirt most often accumulates.
- 💧 Wait for the ice to completely melt without using external heaters.
- 🧽 Wash the internal surfaces of the chambers with warm water and soapy water.
- 🚿 Wipe the rubber door seals, removing all dirt.
- 🌬️ Leave the doors open for 1-2 hours for complete drying and ventilation.
It is important not to turn on the refrigerator immediately after washing. Allow it to dry completely to prevent moisture from getting on the electrical contacts or the control system. In models Hotpoint Ariston electronics are often located in the upper part or in the base, where water can drain during careless washing.
What to do with the water from the pan?
The water from the drain pan must be carefully drained. To do this, the tray is usually removed or tilted. Do not pour this water into the food sink as it may contain bacteria and waste products. After draining, wipe the pan with a dry cloth before putting it back in place.
Cleaning the ventilation and drainage system
One of the key features of the system No Frost is the presence of ventilation ducts and dampers. In two-chamber models Hotpoint Ariston air circulates between the freezer and refrigerator compartments through special openings. Over time, dust, crumbs and ice chips can accumulate in these holes, preventing circulation.
During defrosting, when the ice has completely melted, it is recommended to check these holes. Gently remove visible debris using a soft brush or cotton swab. Do not use sharp objects to avoid damaging plastic baffles or fan blades if the fan is visible.
It is also critical to clean the drain hole. It is located on the back wall of the refrigerator compartment (sometimes hidden by a decorative panel). Through it, condensate and melt water flow into the pan above the compressor. If the hole is clogged, water will accumulate at the bottom of the refrigerator or under the vegetable drawers.
| System element | Location | Cleaning method | Frequency |
|---|---|---|---|
| Drain hole | Rear wall, bottom chambers | Cotton swab or brush | Each defrost |
| Ventilation ducts | Back wall, top/middle | Soft dry brush | Once a year |
| Door seals | Around the door perimeter | Damp cloth with soap | Every defrost |
| Shelves and drawers | Inside the chambers | Warm water, neutral agent | Each defrosting |
To clean the drainage, you can use a special flexible brush, which is often included with a refrigerator, or make an analogue from soft wire wrapped in cotton wool. Push it carefully into the hole and make several rotational movements. Then pour in a little warm water to make sure it drains freely.
⚠️ Attention: If after cleaning there is still water in the drainage hole, ice may have frozen in the drainage tube. In this case, defrosting will be required for a longer time (up to 24 hours) without turning on.
Completion of the process and first start
After all chambers have been thoroughly washed, wiped dry and checked for the absence of moisture, you can begin assembly. Replace all removable shelves, drawers and containers. Make sure that they fit tightly and correctly, especially the guides for the freezer drawers, since in models Hotpoint Ariston they have a specific design.
Now you can plug in the refrigerator. When starting for the first time after defrosting, do not load food immediately. Let the unit run idle for 2-4 hours. This is necessary so that the compressor reaches the required pressure and a stable temperature regime is established in the chambers.
Listen to the operation of the engine. In the first minutes he may work more intensely, this is normal. However, if you hear loud knocking, grinding or humming noises that are different from normal noise, immediately unplug the appliance and check that the drawers are installed correctly and are not touching the fan.
Only after the refrigerator has worked for several hours and the thermometer shows normal values (about +4...+5°C in the refrigerator compartment and -18°C in the freezer), you can load food. Distribute them evenly without covering the ventilation holes on the back wall.
Typical mistakes when defrosting
Even experienced users sometimes make mistakes that can shorten the life of the equipment Hotpoint Ariston. The most common of them is an attempt to speed up the melting of ice with a hairdryer. Hot air can melt the thin plastic of the internal panels or damage the wiring running next to the walls.
Another common mistake is ignoring the drainage system. Users wash shelves but forget to clean the water drainage hole. As a result, after the first cycle of operation, a puddle forms under the vegetable drawers. In two-chamber models, water can even flow into the freezer through the air circulation system.
Some owners try to wash the refrigerator with aggressive chemicals containing chlorine or abrasive particles. This leads to clouding of the plastic, the appearance of microcracks and destruction of the antibacterial coating, if it was applied by the manufacturer. For Hotpoint Ariston it is better to use specialized products or a regular soap solution.
- 🚫 Using a hair dryer or heater to speed up thawing.
- 🚫 Using abrasive sponges and aggressive chemicals.
- 🚫 Ignoring cleaning the drainage hole.
- 🚫 Loading products until the temperature reaches full temperature.
It is also a mistake to turn on the refrigerator ahead of time. If moisture remains inside, it may get on the electrical components and cause short circuits or corrosion of the contacts. Always thoroughly dry the unit before connecting to the network.
