Owners of modern household appliances often ask question about the need for preventative procedures, especially when it comes to cooling systems. For brand devices Hotpoint, as for any other equipment, periodic maintenance is the key to long service. However, the approach to defrosting is radically different depending on what type of cooling system is installed in your model.
If you notice a decrease in operating efficiency, the appearance of ice on the back wall, or it is simply time for scheduled maintenance, it is important to act wisely. Incorrect actions may result in damage evaporator or failure of the electronics. In this article, we will analyze all the nuances of the process, determine whether your device needs defrosting at all, and describe a safe algorithm of action.
The first thing you need to do is identify the type of system. Older models or devices with drip system (Direct Cool) require manual intervention once every 6-12 months. More modern units marked NoFrost or Total NoFrost are equipped with an automatic defrosting system, and they require forced defrosting only in emergency situations or during general cleaning. Understanding this difference is critical to maintaining your warranty.
Determining the type of Hotpoint cooling system
Before you begin any manipulations with the power supply, you need to know exactly what equipment you are dealing with. Models Hotpoint can be equipped with different systems, and an erroneous determination of the type can lead to wasted time or, conversely, ignoring the real problem.
In devices with drip system moisture condenses on the rear inner wall of the refrigeration chamber, freezes, and then, when the compressor is turned off, flows into the drain hole. In the freezer compartment of such devices, ice constantly builds up, and its thickness increases over time. If you see that the layer of frost in the freezer exceeds 5–7 mm, this is a direct signal to action.
Device with technology NoFrost work differently. Cold air circulation is forced, and moisture is removed outside the chambers. In principle, ice does not form in them. If ice appears in such a refrigerator, this indicates malfunction: a problem with the door seal, clogged drainage or a malfunction of the defrost sensors.
- ❄️ Drip system: ice builds up on the back wall of the refrigerator and in the freezer, requires manual defrosting.
- 🌪️ NoFrost: no ice is formed, defrosting is only needed for washing or in case of breakdown.
- 💧 Combined: drip system in the refrigerator compartment, NoFrost in the freezer.
- 🔍 Indication: presence of a snowflake on the control panel often indicates the fast freezing mode, and not the type of system.
Carefully study the technical data sheet or sticker on the device body. Often there are codes by which you can determine the presence of the system automatic defrosting. If the documentation is lost, a visual inspection of the chambers will give an accurate answer: the absence of a visible evaporator (grid or plate) inside the fridge compartment and the presence of many holes for air outlet is typical for NoFrost.
⚠️ Attention: Forced defrosting of a working refrigerator NoFrost more often than 1 time per a year does not make technical sense and only creates an extra load on the compressor when the temperature subsequently rises.
Preparatory stage before defrosting
The preparation process takes longer than defrosting itself and requires careful attention to detail. Product safety and security is our number one priority. You should start by emptying the chambers of their contents.
All products must be removed. If you plan to store them during the procedure, prepare cooler bags or thermal boxes with ice. A short-term increase in temperature of even 10-15 minutes can negatively affect perishable goods such as meat or dairy products. It is also better to remove shelves and drawers for thorough washing.
Next, turn off the power. It is not enough to simply turn off the button on the control panel, if there is one. It is necessary to pull out plug from the socket. This is a safety requirement and a guarantee that the compressor will not start at a time when the refrigerant has not yet stabilized after being idle.
☑️ Preparation checklist
Cover the floor around the unit with absorbents rags or towels. When ice melts, a significant amount of water is generated, and the drainage system may not be able to handle this amount immediately. Also prepare a shallow container to collect water if the ice breaks off in pieces.
Natural defrosting: safe method
The most correct and recommended by manufacturers Hotpoint method is the natural melting of ice. It does not require physical effort and completely eliminates the risk of mechanical damage to internal elements. This method takes from 3 to 24 hours depending on the thickness of the ice and the room temperature.
After you have unplugged the appliance and opened the doors, simply leave it alone. Heat from the room air will begin to be transferred to the walls of the chamber, starting the melting process. There is no need to artificially speed up this process, although many users seek to reduce the waiting time.
Periodically check the tray or rags on the floor. If water begins to flow beyond the designated area, it must be wiped up. It is important to ensure that water does not get on electrical contacts or into the ventilation holes located in the lower part of the case.
- 🕰️ Time: takes from 4 to 12 hours depending on the volume of ice.
- 🛡️ Safety: the risk of damaging the evaporator tubes is zero.
- 💧 Control: requires periodic checking and removal of melt water.
- 🌡️ Temperature: efficiency depends on the temperature in the room (the warmer, the faster).
Is it possible to leave the refrigerator to defrost for night?
Yes, this is even the preferred option. You can start the process in the evening, leave the doors open overnight, and finish cleaning in the morning. The main thing is to make sure that water does not leak to the neighbors below if you do not have sides on the floor.
After the ice has completely melted, wipe the internal surfaces with a dry soft cloth. Make sure there is no debris or pieces of ice left in the drain hole (if your model has one). Only after this can you return the shelves to their place and turn on the device.
Accelerated methods and precautions
Sometimes time is running out, and it is not possible to wait a day. In such cases, accelerated methods can be used, but they require extreme caution. The main goal is not to damage the aluminum evaporator, which is located very close to the inner walls of the chamber. One of the acceptable methods is to use containers with warm water. Pour warm (not boiling water!) water into bowls or pans and place them on the shelves or bottom of the refrigerator. Close the door. The steam and heat from the water will speed up the melting of the ice. You need to change the water as it cools. aluminum evaporator, which is very close to the inner walls of the chamber.

You can also use a fan. Direct a stream of room temperature air into the open chamber. This will increase circulation and speed up heat transfer. However, using a hair dryer, especially in hot air mode, is strictly not recommended.
⚠️ Attention: Using a hair dryer can lead to local overheating of the plastic, deformation of the internal panels and damage to the wiring. In addition, sudden temperature changes are dangerous for case materials.
If you decide to use a hairdryer, keep it at least 30–40 cm away from the ice and constantly move it. Under no circumstances should you direct a stream of hot air at one point for a long time. It is best to use the “cold air” mode, if available, or just warm, but not hot.
Cleaning and care after defrosting
The defrosting period is the ideal time for general cleaning. While the chambers are empty and accessible, it is necessary to remove not only ice, but also dirt, bacteria and unpleasant odors. For the interior surface of the refrigerator Hotpoint mild detergents are suitable.
Prepare a solution of warm water and a small amount of dishwashing detergent or specialized spray for refrigerators. Avoid abrasive powders, hard brushes and aggressive chemicals (chlorine, acetone), as they can damage the antibacterial coating or plastic. Pay special attention to the drainage hole. In models with a drip system, it is located at the bottom of the rear wall. Clean it with a special one antibacterial coating or plastic.
