Owners of modern household appliances are often faced with the misconception that systems No Frost completely eliminate the need for manual maintenance. However Ariston Hotpoint, like any other manufacturer, requires periodic maintenance for stable operation. Many users are surprised to learn that even “smart” units need to be unplugged and thoroughly cleaned at least once a year.
Ignoring this rule can lead to an unpleasant odor, reduced cooling efficiency, and even breakdown of important components. During operation, ice crust accumulates on the walls and in hard-to-reach places, which automation is not always able to remove. That is why defrosting remains a mandatory procedure for maintaining the health of equipment.
In this article we will look in detail at how to properly prepare Ariston Hotpoint for the procedure, what tools will be needed and what absolutely cannot be done. You will learn why frost appears even in systems with complete moisture removal and how to return the device to factory performance without calling a technician.
Why ice forms in the No Frost system
The principle of operation No Frost (literally “without frost”) is forced air circulation and dehumidification. Fans drive air masses through the evaporator, where the moisture condenses and freezes, and then is discharged into a special tray. However, this process is not 100% ideal in the long term.
Over time, microscopic particles of dust, crumbs or grease can accumulate in the drainage system and mix with the water. A viscous substance is formed, which, when frozen, blocks the outflow. As a result, some of the moisture remains inside the chamber or on the back wall, turning into a dense layer of ice.
Hidden freezing mechanism
The evaporator is located behind a plastic panel, so you do not see how it forms ice. When the layer becomes too thick, the sensors may not work correctly, and the system stops starting the defrost cycle on time.
It is also worth considering the tightness of the seals. If the rubber Ariston Hotpoint wears out or becomes dirty, warm, moist air from the kitchen constantly enters the chamber. The system simply does not have time to remove such a volume of moisture, and it settles on the products and shelves in the form of a snow coat.
Preparing for defrosting: step-by-step algorithm
Before starting any work, it is necessary to ensure safety and prepare the space. You can’t just unplug the cord and leave your equipment in chaos. Competent preparation will save you time and nerves, and also protect the floor covering from water.
First, completely empty the chambers. Remove all food, shelves, drawers and containers. Glass can burst if there is a sudden change in temperature, so it is better to wash glass shelves separately with warm water. It is also better to remove plastic elements for thorough washing with a disinfectant.
☑️ Preparation checklist
Move the refrigerator away from the wall to provide access to the back. Place old towels or rags under the bottom and around the device, since when the ice melts, water can flow not only into the drain, but also out. Prepare a basin or syringe in advance for pumping water from hard-to-reach places.
The process of natural and accelerated defrosting
The safest method for Ariston Hotpoint is natural thawing. Leave the doors open for 10-12 hours, preferably overnight. During this time, the ice formations will completely soften and flow into the drainage system. Do not try to speed up the process if you have time to wait.
If time is short, you can use accelerated the technique, but with extreme caution. It is allowed to install containers with hot (not boiling water!) water in the chambers. Warm steam will help soften the ice crust faster. You need to change the water as it cools.
⚠️ Attention: It is strictly forbidden to use hair dryers, fan heaters or heaters to dry the inner chamber. A stream of hot air can deform plastic parts, melt seals, or damage wiring inside the case.
Some users try to chip off the ice with a knife or screwdriver. This in no case cannot be done. Tubes containing refrigerant pass through the walls of the chamber. One awkward move and you will pierce the circuit, after which repairs will become economically unfeasible. Use only soft scrapers made of plastic or wood.
Cleaning the drainage system and channels
After the main body of ice has melted, attention should be switched to the drainage hole. It is usually located on the back wall of the refrigerator compartment. This is where blockages most often form that interfere with water flow.
For cleaning, use a special flexible brush wire or a long soft cable. Carefully insert it into the hole, making rotational movements to break through the plug. Then rinse the canal with warm water using a bulb or a large-volume syringe.
| Tool | Purpose | Limitations |
|---|---|---|
| Soft sponge | Washing walls | Do not use the abrasive side |
| Plastic spatula | Deicing drainage | For soft ice only |
| Syringe/Bear | Flushing the drain | Water not hotter than 50°C |
| Dry rags | Wiping moisture | Lint-free |
Make sure that water flows freely into the compressor pan. If water is standing in the channel, repeat the cleaning procedure. Clean drainage is the key to the absence of puddles under the refrigerator and the correct operation of the system. No Frost.
Care for seals and ventilation holes
While the chambers are open and empty, it’s time to pay attention to the rubber seals on the doors. They are the ones responsible for thermal insulation. Wipe them with a soft cloth soaked in a mild soap solution, and then wipe dry.
If the rubber has lost its elasticity and become hard, you can lubricate it with a special silicone-based product or regular Vaseline. This will extend the life of the material and improve the fit of the door. Check for cracks or tears in the rubber.
⚠️ Attention: Do not use solvents, alcohol or aggressive household chemicals to wipe the seals. They overdry the rubber, making it brittle, which will lead to loss of seal.
Also inspect the ventilation holes inside the chambers. T Ariston Hotpoint hey can be located on the back wall or on the ceiling of the chamber. Make sure they are not clogged with crumbs or packaging debris. Air circulation must be free for uniform cooling.
Completing the procedure and first start-up
After thoroughly washing and removing all moisture, allow the refrigerator to dry completely. Wipe all surfaces with a dry cloth. Leave the doors open for another 30-60 minutes to remove any remaining moisture.
Put all shelves and drawers in their places. Make sure they are securely fastened. Now you can connect the device to the network. Do not load the products immediately - let refrigerator run idle for 2-3 hours so that it reaches operating temperature.
After the thermostat turns off the compressor for the first time, you can carefully load the products. Try not to fill the chamber completely at once, leave space for air circulation. Regularly repeating this procedure once a year will save you from many problems in the future.
Is it necessary to defrost No Frost if there is no ice visible?
Yes, preventive defrosting is recommended even in the absence of visible ice. This allows you to clear hidden ventilation channels and drainage from microscopic deposits, which over time turn into clogs.
How long should equipment dry after defrosting?
1 hour of active drying with a towel and airing is enough. However, before turning it on, make sure that the area of the compressor and electrical contacts is absolutely dry.
What to do if the refrigerator does not freeze after defrosting?
Check whether the doors are tightly closed and whether the “Vacation” or “Super Freeze” mode is turned on. If after 4-5 hours of operation the temperature does not decrease, it is possible that the circuit was damaged during cleaning or the sensor settings were lost - you will need to call a technician.
