Modern kitchen appliances, such as Hotpoint Ariston, are famous for their reliability and functionality, but even the most advanced systems require periodic maintenance. Owners of built-in models are often faced with the need for complete defrosting, especially if the unit is not equipped with a system No Frost or requires general cleaning. Ignoring this process can lead to a decrease in energy efficiency, the appearance of unpleasant odors and even compressor breakdown due to overload.
Built-in refrigerators have their own specifics: they are tightly surrounded by furniture, which limits air circulation and requires a special approach to placement and maintenance. Defrosting such a device is not just waiting for the ice to melt, but a set of measures, including niche preparation, proper shutdown and subsequent maintenance of seals and shelves. In this article, we will analyze in detail the algorithm of actions that will help you safely carry out the procedure and extend the life of your equipment.
Before taking active steps, it is important to understand what kind of cooling system you are dealing with. Models with a drip system (Drip System) require manual defrosting every 4-6 months, while systems No Frost need this much less frequently, usually only in case of emergency icing or deep cleaning. Understanding the design of your Hotpoint Ariston will help you avoid unnecessary mistakes and save time.
Determining the type of cooling system and preparation
The first step before starting any work is to accurately determine the type of cooling system of your refrigerator. Most built-in models are Hotpoint Ariston equipped with a No Frost or Low Frostsystem, which greatly simplifies maintenance, but does not completely eliminate the need for periodic defrosting. If you notice that a “fur coat” more than 5-7 mm thick has formed on the back wall of the freezer, or the door no longer closes tightly due to ice on the seal, the procedure becomes mandatory.
Preparing for the process takes longer than defrosting itself, especially in the case of built-in appliances. You will need to clear some space around the niche as access to the rear of the cabinet may be difficult. Make sure that you have access to an electrical outlet, which is usually located in a nearby cabinet or kitchen plinth. Safety —priority number one: any manipulation of electrical appliances requires a complete disconnection from the network.
⚠️ Attention: Never try to move built-in refrigerator without checking the reliability of the countertop and side walls. The furniture set may be heavier than the unit itself, and careless movement will damage the facades or disrupt the geometry of the niche.
Prepare a place for storing food in advance. Since the process can take anywhere from 3 to 24 hours depending on the amount of ice and the room temperature, food should not be left at room temperature for too long. Use cooler bags, insulated containers, or temporarily move supplies to another refrigerated location. You will also need old towels, basins for water and, possibly, a bulb syringe for pumping out moisture from hard-to-reach places.
Step-by-step instructions for defrosting a built-in model
The process of defrosting a built-in refrigerator Hotpoint Ariston requires consistency. Start by completely emptying the chambers: remove all products, shelves, drawers and containers. It is better to take glass shelves and plastic elements into a warm room in advance so that the temperature difference during washing does not become critical for them. After this, disconnect the device from the power supply. If the outlet is in a hard-to-reach location, use an extension cord or temporarily turn off the circuit breaker at the panel if it is safe to do so and will not affect other vital appliances.
Open the refrigerator and freezer doors as wide as possible. If the installation design allows it, remove the doors or at least loosen their fastenings to ensure better flow of warm air inside. However, in most built-in models it is difficult to do this without dismantling the facades, so limit yourself to maximum opening. Leave the unit alone. Natural melting of ice is the safest method for evaporator and internal panels.
During the melting process, water will flow into a special groove at the bottom of the refrigerator compartment and then into the drainage hole. Make sure the water drain tube is not kinked or clogged. There can be a lot of water in the freezer, so place thick towels on the bottom that will need to be wrung out periodically, or place low containers. It is important to prevent water from overflowing over the side onto the kitchen floor, as moisture can damage the flooring or the lower parts of the furniture set.
☑️ Checklist before defrosting
How to speed up the process without harm to equipment
Natural defrosting can last up to a day if the ice layer is large and the room temperature is low. Many users try to speed up this process, but here lies the main danger. It is strictly forbidden to use sharp objects (knives, screwdrivers, scrapers) to chip ice. Aluminum tubes evaporator in models Hotpoint Ariston are located very close to the surface, and even a slight puncture will lead to a refrigerant leak and expensive repairs, which are often not economically feasible.
For safe acceleration, you can use the following methods:
- 🌡️ Installing a fan: direct a flow of warm (but not hot!) air from a regular room fan into the open chambers of the refrigerator. This will increase circulation and speed up melting.
- 💧 Hot water containers: place bowls of hot water (about 50-60 degrees) on the shelves (after covering them with towels). Change the water as it cools. The steam will help soften the ice.
- 🧣 Warm compresses: apply towels soaked in hot water to particularly icy areas. This will locally increase the temperature and help the ice move away from the walls.
Use of a hair dryer is permissible only with extreme caution and only in cold air or minimal heating mode, directing the jet strictly at the ice, and not at plastic parts or rubber seals. Overheating of the plastic can lead to its deformation, after which the door will no longer close tightly. Patience in this matter is the key to the safety of the equipment.
⚠️ Attention: Do not use heaters, heat guns or hair dryers at maximum heat in the immediate vicinity of the internal walls of the refrigerator. A sharp temperature change can cause cracks in the plastic inner box or damage electronic sensors.
Why can’t you defrost with a hairdryer at full power?
Using a powerful hairdryer can lead to local overheating of the plastic from which the inner box of the refrigerator is made. This causes deformation of the walls, the appearance of microcracks and disruption of the geometry of the shelves. In addition, hot air can melt the adhesive that holds the seals in place or damage the insulation of the wires, which will lead to a short circuit or cold leakage in the future. It is safer to wait longer than to risk the integrity of the case.
Caring for the No Frost system and removing ice
If your Hotpoint Ariston is equipped with a system No Frost, the formation of ice inside the chambers during normal operation is impossible. The appearance of snow or ice crust indicates a malfunction: most often it is a loose door fit, damage to the seal or a malfunction of the evaporator defrost. In such cases, defrosting is a temporary measure to diagnose and eliminate the symptom, but not the cause.
When defrosting the system No Frost pay special attention to the drainage hole. Often it is its clogging with crumbs or mold that leads to condensation not leaving, freezing and blocking the air circulation channels. Clean the hole using a special brush or soft wire wrapped in cotton wool. Pour some warm water in there to make sure there is free flow.
After the ice has completely melted and the drainage has been cleaned, thoroughly dry all surfaces. In systems No Frost moisture is the main enemy, as it can freeze in the ventilation ducts and block the fan. Make sure the area where the evaporator is located (usually behind the back of the freezer) is dry and clean. If you find a lot of ice there, you may need more serious repairs with the participation of a specialist.
Cleaning and disinfection after defrosting
The defrosting period is the ideal time for general cleaning. While the chambers are empty and accessible, all dirt, bacteria and odors must be removed. To wash internal surfaces, use a soft sponge and a warm solution of baking soda (1 tablespoon per liter of water) or a special refrigerator cleaner. Aggressive chemistry, abrasive powders and chlorine-containing products can damage the antibacterial coating of the walls and plastic.
Pay special attention to the rubber seals on the doors. Dirt and mold often accumulate in the folds, which disrupt the seal. Wipe them with a cotton swab dipped in a solution of vinegar or hydrogen peroxide. After cleaning, the seals can be lubricated with silicone grease or a special rubber conditioner to maintain their elasticity and prevent cracking.
Be sure to wash and dry all shelves, drawers and containers before putting them back. Wet surfaces will become covered with frost immediately after turning on the refrigerator. Allow all items to dry completely at room temperature. Also wipe the outer parts of the case and ventilation grilles (if accessible), as dust on them impairs heat transfer.
Starting the refrigerator and temperature control
After completing all defrosting and cleaning procedures, put all shelves and drawers in their places. Make sure they are secured correctly and do not interfere with the free movement of air. Close the doors and only now connect the refrigerator to the electrical network. Do not rush to load products: let the unit run idle for at least 2-3 hours (for some models up to 6 hours) so that it reaches the required temperature and stabilizes the compressor operating mode.
In modern models Hotpoint Ariston with electronic control, after switching on, it may be necessary to adjust the temperature conditions. Check if the settings have been reset to factory settings. The optimal temperature in the refrigerator compartment is +4...+5°C, in the freezer - -18°C and below. You can control the temperature using the built-in display or a separate thermometer placed in a glass of water on the middle shelf.
| Work stage | Duration (approximately) | Key action |
|---|---|---|
| Preparation | 20-30 minutes | Shutdown, removing products |
| Defrosting | 3 - 24 hours | Natural melting of ice |
| Cleaning | 30-40 minutes | Washing chambers, shelves, seals |
| Drying and starting | 2-4 hours | Temperature set without load |
If, after starting, you notice that the refrigerator runs continuously without turning off, or makes unusual sounds, check that the doors are tightly closed and that there are no obstructions to air circulation. During the first hours of operation, the compressor may make more noise than usual - this is normal for the start-up phase. However, if the situation has not returned to normal after a day, you should contact a service center.
Frequently asked questions (FAQ)
Is it possible to defrost a Hotpoint Ariston refrigerator without removing it from its niche?
Yes, in most cases it is not possible to remove the refrigerator from a furniture niche required if there is access to the rear wall for ventilation and the ability to open the doors 90 degrees or more. However, if ice has formed on the rear outer wall (which happens with insulation problems), it may be necessary to partially dismantle the side panels of the cabinet for access.
How long should a defrosted refrigerator sit before turning it on?
Special “settle” time is not required for modern models, unless you used aggressive defrosting methods with a lot of water inside. The main thing is to wipe all surfaces dry and let the compressor cool down if it has just been running. You can turn it on immediately after assembly, but it is better to load food after 2-3 hours of operation.
What to do if after defrosting the refrigerator does not freeze?
If after 6-8 hours of operation the temperature does not drop, check whether the doors are tightly closed and whether the seals are stuck. Also make sure the freezer fan (if equipped) is spinning. If the problem persists for more than a day, the system may have developed an ice plug in the capillary tube or an electronics failure has occurred, which requires calling a technician.
Does the No Frost system need to be defrosted?
The system No Frost does not require regular defrosting to remove ice, as it does this automatically. However, once a year it is recommended to carry out a complete defrosting and washing for hygiene, removing dust from the evaporator (via drainage) and checking the operation of the fans. This will extend the life of the equipment and ensure the freshness of the products.
