Operation of modern brand household appliances Hotpoint Ariston requires compliance with certain maintenance rules, especially when it comes to cyclic maintenance of freezers. Despite the widespread belief that systems are completely autonomous No Frost, many owners are faced with the need to carry out preventive defrosting or eliminate the consequences of a malfunction of the automation. Ignoring this process can lead to a decrease in cooling efficiency, increased energy consumption and even failure of the compressor.
Owners of models with a classic cooling system or a hybrid system Low Frost need to regularly carry out manual defrosting, since the ice crust on the evaporator significantly worsens heat transfer. Even in units with automatic defrosting, user intervention may be required over time to clean hard-to-reach places or reset electronic errors. It is critically important to understand that complete defrosting takes at least 24 hours, and accelerating this process mechanically is prohibited.
This article examines in detail the action algorithms for various series of refrigerators, explains the operation of protective mechanisms and defrost timers. We will look at why the indicator is blinking, how to properly prepare equipment for long periods of downtime, and what mistakes users make when trying to quickly get rid of ice. A competent approach to maintenance will extend the service life of refrigerant and seals.
⚠️ Attention: Before starting any work on servicing refrigeration equipment, be sure to ensure that the power cord is removed from the electrical outlet. Working with electrical appliances in a damp environment or with water on the floor creates a risk of electric shock.
Features of cooling systems in Hotpoint Ariston refrigerators
Refrigerators Hotpoint Ariston are equipped with various types of cooling systems, and the defrosting method directly depends on the installed technology. Most modern models use a system No Frost, which involves the circulation of cold air and automatic evaporation of condensate. In such units, ice should not form on the walls of the chamber in normal mode, however, periodic maintenance is still required.
A less common system, but found in budget or older series, is the system (drip) or its improved version Direct Cool (drip) or its improved version Low Frost requires mandatory manual intervention. In these models, moisture settles on the back wall, freezes and periodically thaws when the compressor stops, but ice constantly builds up in the freezer. If you do not know which system is installed in your device, refer to the technical documentation or find the model on the rear panel.
Automated defrosting process control in models with an electronic controller monitors the evaporator temperature. When the sensor records a certain value, it turns on Defrosting heating element, which melts the formed frost. The water flows into a special tray and evaporates. A malfunction of this mechanism often becomes the reason why the user has to defrost the chamber manually.
⚠️ Attention: The design of the drainage system may vary depending on the year of manufacture and the specific model. Technical characteristics and arrangement of elements may be changed by the manufacturer without prior notice, so always check the device data sheet.
Understanding the operating principle of your model will help you avoid unnecessary steps. For example, trying to start the fast freezing mode Super Freeze when the evaporator is already icy will not solve the problem, but will only load the compressor. At the same time, knowing the location of the heating elements allows you to correctly organize the process of natural thawing.
When manual defrosting of the freezer is necessary
There are a number of signs that clearly indicate that your refrigerator Hotpoint Ariston requires forced defrosting. The first and most obvious signal is a visible decrease in the useful volume of the chamber due to the growth of an ice coat. If the layer of frost or ice exceeds 5-7 millimeters, the efficiency of the unit decreases and the load on the motor increases.
The second important indicator is the behavior of the temperature regime. If the food in the freezer begins to thaw, and the compressor runs almost non-stop, this indicates a violation of heat exchange. The ice shell on the evaporator works as an insulator, preventing cold from penetrating into the chamber, which forces thermostat to keep the compressor on constantly.
- 🧊 A thick layer of ice is visible on the walls of the chamber or on the products, preventing closure doors.
- 🌡️ The temperature in the chamber does not drop to the set values even at the maximum power setting.
- 🔊 The compressor makes unusual sounds or operates in a continuous cycle without a rest phase.
- 💧 Water appears under the refrigerator or inside the chamber, which does not keep up evaporate.
Also, defrosting is required after a long power outage or when moving. If the refrigerator was left unplugged for more than a day, condensation could form in the system, which would turn into ice when turned on again. In such cases, it is necessary to let the unit stand in the off state with the doors open for at least a day.
Why can’t you ignore ice?
Ignoring ice growth leads to the compressor working for wear, trying to compensate for poor heat transfer. This can cause overheating of the windings, jamming of the piston group and expensive repairs or replacement of the motor. In addition, ice blocks the ventilation holes, creating zones with different temperatures, which spoils the food.
Step-by-step instructions: preparation and defrosting process
The process of properly defrosting the refrigerator Hotpoint Ariston requires sequential steps. You should start with preparation: empty the freezer of food. If defrosting is planned, take care in advance of where frozen foods will be stored so that they do not have time to defrost. Place them in thermal bags or transfer them to another cold place.
After the chamber is empty, turn off the power. Don't just turn off the button, if there is one, but unplug the plug from the socket. This is necessary for complete deactivation of electronics and safety. Leave the freezer and refrigerator doors open. It is recommended to place an absorbent cloth or a flat tray under the bottom of the refrigerator, where the base or grill is usually located, since when the ice melts, water can flow out.
Now all you have to do is wait. The natural process of ice melting takes time. For models with a system No Frost this may take less time, since there is usually less ice there, but it takes time for the channels to dry completely. It is strictly forbidden to use hair dryers, hot water or heating devices to speed up the process. A sudden temperature change can damage the plastic of the inner chamber or cause cracks in the evaporator tubes.
| Stage | Action | Execution time |
|---|---|---|
| Preparation | Shutdown, cleaning chambers | 15-20 minutes |
| Main defrosting | Natural melting of ice | From 6 to 24 hours |
| Cleaning | Removing water and dirt | 20-30 minutes |
| Startup | Turning on and setting the temperature | 2-4 hours |
While the refrigerator is defrosting, you can start cleaning the shelves and boxes. They should be washed with warm water and a mild detergent and dried thoroughly. Don’t forget to also wipe the rubber seals on the doors, since dirt stuck to them can break the seal.
Cleaning and care after thawing
When all the ice has melted and the water has drained, you must carefully remove any remaining moisture inside the chamber. Use a soft, absorbent cloth. Pay special attention to the corners of the chamber and where the drainage hole exits. Stagnation of water in these places can lead to an unpleasant odor or bacterial growth.
The drainage hole is a critical element of the system. In refrigerators Hotpoint Ariston it is often located on the back wall or on the floor of the chamber. If it is clogged with crumbs or mold, the water will not go into the pan, but will begin to accumulate at the bottom and flow out. For cleaning, you can use the special brush included in the kit, or a soft wire wrapped in cloth.
- 🧼 Wipe the inner walls with a solution of baking soda (1 tablespoon per liter of water) for disinfection.
- 🍋 To eliminate odors, you can use a weak solution of citric acid or special odor absorbers.
- 💨 Leave the doors open for another 30-40 minutes after cleaning, so that the interior is completely dry.
After drying, assemble the refrigerator by placing the shelves and drawers in their places. Make sure that all the guides fit correctly and that nothing interferes with the free movement of the drawers. Only after complete assembly and drying of all elements can you connect the device to the network.
