Modern refrigeration units of the brand Hotpoint Ariston are famous for their reliability and energy efficiency, but even the most advanced equipment requires regular maintenance. Many owners mistakenly believe that the presence of a system NoFrost completely eliminates the need for defrosting, but this is not entirely true. Ice crust can build up on the evaporator hidden behind plastic panels or in drainage channels, which over time leads to a decrease in compressor performance and the appearance of unpleasant odors.
The process of cleaning the internal chamber from ice is not just a matter of hygiene, but also a way to extend the life of expensive equipment. If you ignore ice build-up, the compressor will be forced to work in increased mode, trying to maintain the set temperature, which inevitably leads to increased energy consumption. In this article, we will analyze in detail the algorithms of action for various models, including devices with Total NoFrost and the classic drip system.
Before starting any manipulations, it is important to understand what kind of modification you are dealing with, since approaches to maintenance may differ significantly. Incorrect actions, such as chipping ice with a knife, can cause the cooling system to leak, which is a costly failure. Let's look at how to properly prepare equipment for “rest” and what absolutely cannot be done.
⚠️ Attention: Never use sharp objects (knives, screwdrivers, ice picks) to chip ice inside the chamber. One careless movement can damage the thin-walled evaporator, resulting in a refrigerant leak and requiring professional repair.
Determining the type of defrost system
The first and most important step is to accurately determine the type of defrost system in your specific device Hotpoint Ariston. The frequency of procedures and their complexity depend on this. There are three main types in the brand’s model range: the classic “crying” system, partial NoFrost (only in the freezer) and complete Total NoFrost. You can find out the type of your model by looking at the technical data sheet or the sticker inside the case.
Devices with a drip system require the most frequent intervention, as moisture condenses on the back wall of the main chamber and flows into a groove that can become clogged. In these models, ice forms directly on the rear panel of the refrigerator compartment. The freezer can be equipped with manual control or a LowFrost system, where ice grows more slowly, but still appears.
Models with full NoFrost equipped with a complex system of fans and heating elements that automatically remove moisture. However, even they require periodic preventative defrosting at least once a year. This is necessary to clean hard-to-reach places where dust and bacteria can accumulate, as well as to check the operation of the drainage hole. Ignoring this rule may result in water beginning to accumulate at the bottom of the refrigerator or under the drawers.
Preparing the refrigerator for defrosting
Quality preparation is half the success of the entire operation. Before disconnecting the device from the power supply, it is necessary to empty the chambers of food. If it’s winter outside, you can take perishable food items out to the balcony after pre-packing them. In the warm season, it is better to put food in thermal bags or pots with cold water to minimize the risk of spoilage during the procedure.
Remove all removable elements: shelves, vegetable drawers, egg trays and bottle holders. They should be washed separately with warm water and a mild detergent. It is better not to expose plastic parts to hot water to avoid deformation, especially if they are made of polystyrene. After washing, let them dry completely.
Prepare a place to collect water in advance. Despite the presence of drainage systems, when a large amount of ice melts, the water may not have time to go into the drain hole. Place several layers of old towels or rags on the floor in front of the refrigerator. You will also need soft sponges and dry microfiber cloths to collect moisture inside the chambers.
Step-by-step defrosting process
After all the preparatory steps are completed, you can begin the main process. Disconnect the Hotpoint Ariston refrigerator from the power supply. Don't just turn off the button, if there is one, but unplug the plug from the socket. This will ensure complete safety and stop the compressor.
Leave the refrigerator and freezer doors completely open. To speed up the process, you can place containers with hot water inside the chambers, but not boiling water, so as not to damage the plastic. Close the doors for 10-15 minutes to let the steam soften the ice, then open them again. Repeat the procedure several times. It is strictly forbidden to use a hairdryer to speed up the melting, as hot air can damage seals and plastic elements.
While the ice is melting, start cleaning the drainage hole. It is usually located at the back of the refrigerator compartment. Use a special flexible brush or cotton swab dipped in warm water to clean the canal. This will prevent the formation of puddles at the bottom of the refrigerator after it is turned on.
Cleaning and disinfecting internal surfaces
When all the ice has melted and the water has collected, you need to thoroughly wash the internal surfaces. Use a baking soda solution (one tablespoon per liter of water) or a weak vinegar solution. These products do an excellent job of killing bacteria and neutralizing unpleasant odors without leaving chemical traces.
Wipe all the walls, ceiling and bottom of the chambers with a soft sponge. Pay special attention to the rubber seals on the doors. Mold and dirt often accumulate in the folds of the seals, which can cause the door to not fit tightly. Wipe them with a cotton swab dipped in the cleaning solution.
After wet cleaning, be sure to wipe all surfaces dry with a clean rag. The remaining moisture may turn back into ice the first time you turn it on, ruining all your efforts. Let the refrigerator stand open for another 15-20 minutes so that any remaining moisture completely evaporates and the smell of cleaning products disappears.
| Element | What to wash | What not to do | Frequency |
|---|---|---|---|
| Chamber walls | Soda solution, special means | Abrasives, chlorine | When defrosting |
| Rubber seals | Warm water, vinegar | Oils, solvents | Once every 3 months |
| Shelves and drawers | Warm water with soap | Steep boiling water | When defrosting |
| Drainage hole | Brush, warm water | Sharp objects | Once every six months |
Completion of the procedure and first start
After making sure that the inside is dry and clean, put all the shelves, drawers and trays in their places. Check that all guides are inserted straight and all the way. Now you can turn on the refrigerator Hotpoint Ariston to the network. It is recommended not to load the chambers with food for the first few hours so that the device returns to operating mode and stabilizes the temperature.
Set the recommended temperature conditions. For the refrigerator compartment, the optimal temperature is considered to be from +2 to +4 degrees, for the freezer - -18 degrees and below. You should not immediately set the minimum values, unless this is urgently necessary, this will create an extra load on the compressor.
After 3-4 hours, check the operation of the device. Make sure that the compressor is running smoothly, without any unusual knocks, and that there is condensation on the back wall of the refrigerator compartment (if it is a drip system). If everything is in order, you can gradually fill the chambers with products.
Typical mistakes and precautions
One of the most common mistakes is the use of chemicals with a strong odor or abrasive powders. The plastic used in refrigerators Hotpoint Aristonhas a porous structure and easily absorbs odors, which are then very difficult to get rid of. In addition, abrasives scratch the surface, creating an ideal environment for the growth of bacteria.
Another common mistake is turning on the refrigerator immediately after defrosting, without allowing it to dry. Residual moisture can get on electrical contacts or freeze in the drainage system, blocking the flow of water. Always dry the unit thoroughly before connecting to the network.
⚠️ Attention: Do not try to speed up the defrosting process by heating the ice with a hairdryer or placing a pan of boiling water inside without a stand. A sudden change in temperature can lead to cracks in the plastic box of the freezer.
Also, do not leave the refrigerator to defrost unattended for a long time, especially if you have pets or small children. Open doors and puddles of water on the floor can cause injury or damage to property.
Frequently asked questions (FAQ)
How often do you need to defrost a Hotpoint Ariston refrigerator with the NoFrost system?
Even with the NoFrost system, manufacturers recommend a full defrost and wash refrigerator once a year. This is necessary for hygienic cleaning and checking the operation of the drainage system, which may become clogged with crumbs or mold.
Is it possible to defrost the refrigerator by simply turning off the button, but without pulling out the plug?
No, it is not safe. To completely defrost, you must completely de-energize the device by removing the plug from the socket. This ensures that the compressor will not start accidentally while the ice is melting, and eliminates the risk of a short circuit when water comes into contact with electrical components.
Why does the refrigerator not freeze for a long time after defrosting?
After defrosting, the refrigerator takes time (from 2 to 6 hours) to return to operating mode. If you loaded it with food right away, the cooling process will take longer. Also check the tightness of the door and the operation of the thermostat.
What is the best way to wash plastic drawers inside the refrigerator?
Plastic drawers are best washed with warm water with the addition of a mild dishwashing detergent or laundry soap. Avoid using hot water (above 50 degrees), as the plastic may become deformed and stop closing tightly.
