Modern household appliances of the Italian brand Ariston i Hotpoint are famous for their reliability, but even the most advanced equipment requires periodic maintenance. Many owners mistakenly believe that systems No Frost or Frost Free completely eliminate the need to defrost the unit, but this is not entirely true. Regular maintenance is necessary to maintain energy-saving properties and extend the service life of the compressor.
Incorrect actions during defrosting can lead to damage to the evaporator or failure of the thermostat, so it is important to clearly understand the algorithm of actions specifically for your model. In this article, we will analyze in detail how to safely carry out the procedure, how long it will take, and what nuances are typical for the equipment of these brands. You will learn why you can’t use a hairdryer and how to distinguish normal ice melting from a malfunction.
Features of Ariston and Hotpoint defrosting systems
The equipment of these brands is most often equipped with a combined moisture removal system. In the freezer compartment, the principle is usually implemented No Frost, where the fan drives dry cold air, and in the refrigerator compartment it works drip system (Direct Cool). In the latter case, moisture condenses on the back wall, freezes into a thin crust, and then thaws during the compressor idle cycle, flowing into the drainage tray.
Despite the automation of processes, ice may form in the freezer over time due to frequent opening of the door or violation seal tightness. If you notice that the drawers have become worse at closing or a characteristic crunch of ice has appeared, then it’s time for manual defrosting. Ignoring this signal may result in the ice coat blocking the air ducts and the cooling efficiency will decrease.
⚠️ Attention: In models with full No Frost full defrosting is required less often (once every 1-2 years), but it is necessary to clean hidden cavities from dust and bacteria that are not removed by filters.
It is important to understand the difference between the normal defrost cycle and emergency ice accumulation. The normal cycle occurs unnoticed by the user, while the emergency mode signals problems with Thaw heating element or the timer. If your Hotpoint requires defrosting more than twice a year, you should think about diagnostics.
Preparing the refrigerator for defrosting
Before starting the procedure, it is necessary to properly prepare the unit to minimize the risk of food spoilage and damage to internal surfaces. The first step is to empty the cameras of their contents. All perishable products should be removed and, if possible, transferred to another cold place or used thermal bags.
Next, you need to disconnect the device from the power supply. Simply turning the temperature dial to zero is not enough - you need to physically unplug the cord from the outlet. This is critical for safety, since the water produced when ice melts conducts electricity. It is also worth preparing a place for collecting water.
☑️ Preparing for defrosting
To collect melt water, it is best to use flat trays or baking sheets that are placed under the freezer. If the design of the model Ariston allows, you can carefully tilt the unit, but this must be done extremely carefully so that oil from the compressor does not enter the refrigerant circuit.
- 🧼 Prepare in advance a soft rag and a neutral detergent for wiping the internal walls after defrosting.
- 🪣 Make sure you have a sufficient number of containers, as the volume of melting water can be significant.
- 🌡️ Leave the doors open to allow natural circulation of warm air inside the chambers.
- 🔌 Check that the power cord is not lying in a potential water spill area.
Natural defrosting: step-by-step algorithm
The safest method recommended by manufacturers is natural defrosting. It does not require the use of additional tools and eliminates the risk of thermal shock to the plastic and metal evaporator tubes. The process takes from 3 to 10 hours, depending on the thickness of the ice and the temperature in the room.
After you have turned off the device and opened the doors, you can only wait. You can speed up the process by simply providing a flow of warm air into the room, but without forcing it inside. At this time, you can start washing the shelves and drawers that were removed from the refrigerator.
When the main body of ice begins to separate from the walls, carefully remove large pieces with gloved hands. Do not use force if the ice is holding tightly - it is better to wait a little longer. Residual moisture should be collected with a dry cloth or sponge, paying special attention to the corners and joints of the panels.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers, scrapers) to chip ice. You may accidentally puncture evaporatorwhich will lead to a freon leak and costly repairs.
The final stage of natural defrosting is to thoroughly wipe all surfaces dry. No moisture should remain anywhere, especially in the area of the drainage hole. After this, the doors can be left open for another 15-20 minutes for final ventilation and odor elimination.
What you should absolutely not do
There are a number of common myths and "grandmother's methods" that can irrevocably ruin your Ariston or Hotpoint. Most often, mistakes are associated with the desire to speed up the ice melting process by any available means. However, haste in this case is the main enemy of technology.
Using a hair dryer is one of the most common mistakes. The flow of hot air creates a sharp temperature difference, which can lead to deformation of plastic panels, cracks in the evaporator housing or damage to the wiring. In addition, moisture in the air can condense on hot electronic components, causing a short circuit.
- 🚫 Do not pour hot water directly onto the ice crust - this will stress the materials.
- 🚫 Do not use steam generators or steamers inside refrigerator compartments.
- 🚫 Do not place bowls of boiling water inside without a protective stand - the plastic bottom may melt.
- 🚫 Do not turn on the refrigerator until you are sure that it is completely dry inside.
Why can’t you heat with a hairdryer?
Using a hairdryer creates local overheating zones. The plastic becomes brittle and cracks, and sudden temperature changes can disrupt the tightness of the soldering of the evaporator tubes. In addition, wet steam from the hair dryer can settle on the electrical contacts, causing corrosion or short circuiting.
Another mistake is turning on the device before it is completely dry. If moisture gets on the thermostat contacts or in the compressor area, it may cause electronic malfunction. Give the equipment time to “rest” and dry naturally.
Caring for the drainage system and seals
While the refrigerator is defrosted and open, this is the ideal time to service elements that are usually hidden from view. Particular attention should be paid to drainage holelocated on the back wall of the refrigerator compartment. It is through this that the condensate flows into the evaporation tank above the compressor.
Often the hole becomes clogged with crumbs or mucus, which leads to water beginning to accumulate at the bottom of the refrigerator or under vegetable drawers. You can clean the canal using a special flexible brush or soft wire wrapped in cotton wool.
| Element | Frequency of cleaning | Remedy | Risk of ignoring |
|---|---|---|---|
| Drainage hole | Every defrost | Warm water, brush | Puddles on the floor, mold |
| Door seal | Once every 3 months | Soap solution | Loss of tightness, ice |
| Fan (No Frost) | Once a year | Dry brush | Noise, poor cooling |
| Condenser grille | Once a year | Vacuum cleaner | Overheating compressor |
It is also necessary to inspect the rubber seal along the perimeter of the door. Wipe it with a damp cloth and mild detergent, removing any sticky residue. If the rubber has lost elasticity or has cracks, the door will not fit tightly, allowing warm air to pass through, which is the main reason for the formation of ice.
Starting and checking operation after defrosting
After all cleaning and drying procedures have been completed, you can begin starting up. Plug in the refrigerator. Modern models Hotpoint i Ariston may have a self-diagnosis system, so the first minutes after switching on the device can operate in test mode.
Do not load products immediately. Let the refrigerator run idle for 1-2 hours so that it reaches the required temperature and stabilizes the operating mode. Only after the thermostat turns off the compressor for the first time, you can gradually load food.
Pay attention to the sounds made by the device. A slight gurgling or hissing sound is normal as the refrigerant begins to circulate through the system. However, loud knocking, vibration or buzzing should alert you. Also check whether water appeared under the refrigerator during the first hours of operation.
⚠️ Attention: If after defrosting the refrigerator does not freeze or works without stopping for more than 5-6 hours, there may be air left in the system or a freon leak has occurred. In this case, you need to contact a service center.
Regular maintenance, including proper defrosting and cleaning, allows the equipment to serve for 10-15 years without serious breakdowns. Do not neglect these simple rules, and your refrigerator will delight you with stable operation.
What to do if an unpleasant odor appears after defrosting?
If the smell remains after defrosting, wipe the internal surfaces with a solution of baking soda (1 tablespoon per liter of water) or vinegar. You can also place activated carbon or a special odor absorber tablet inside.
Frequently asked questions (FAQ)
How long does it take on average to defrost an Ariston refrigerator?
The time depends on the thickness of the ice and the temperature in the room. Typically the process takes from 3 to 6 hours. If the ice crust is very thick, it may take up to 10-12 hours to completely melt and dry.
Is it necessary to defrost a refrigerator with a No Frost system?
Yes, at least once a year. The No Frost system prevents the formation of visible ice, but does not protect against dust, bacteria and odors that accumulate inside. The drainage system also needs to be cleaned.
Can vinegar be used to clean the inside of the refrigerator?
Yes, a weak solution of table vinegar (9%) perfectly disinfects and removes odors. However, after treating the surfaces, you need to thoroughly wipe them with clean water to remove the smell of acid.
Why does the refrigerator not turn off for a long time after defrosting?
This is normal in the first hours of operation. The compressor needs time to cool the empty volume of the chambers to the set temperature. If the mode does not stabilize after 6-8 hours, check that the door is closed tightly.
