Owners of brand refrigeration equipment Vestfrost often face the need for scheduled defrosting, even if the unit is equipped with a system No Frost. Despite manufacturers' assurances of complete automation of the process, the accumulation of ice in the evaporator or the formation of ice on the seals and the bottom of the chamber is inevitable. Ignoring this process can lead to reduced cooling efficiency and increased energy consumption.
Modern models require a delicate approach, since complex electronics and sensitive sensors are hidden inside. Incorrect cleaning actions can provoke thermostat malfunctions or damage the plastic structural elements. It is important to understand that even if the ice is not visible to the eye, it can block the ventilation ducts.
The procedure requires time and compliance with certain safety rules. You can’t just turn off the device from the network and wait for a miracle - you need to prepare a place for thawing water and ensure the room is ventilated. In this article we will analyze in detail all the stages so that your Westfrost refrigerator lasts for many years.
Why does ice form in the No Frost system
Many users mistakenly believe that the system No Frost completely eliminates the appearance ice. In fact, the technology only prevents its accumulation on the chamber walls by directing moisture into a special evaporator compartment. There, the ice is periodically thawed by a heating element, and the water evaporates.
However, if drainage system it becomes clogged with dust or food debris, the moisture does not have time to leave and freezes. This creates a plug that blocks the flow of new water. As a result, ice begins to accumulate inside the technical compartment, which over time can lead to failure Defrost heating element.
⚠️ Attention: If you notice that the back wall of the freezer is covered with a “fur coat,” this is a direct signal of a malfunction of the moisture removal system or failures in the defrosting cycle.
A door that is not tightly closed may also be the cause. The entry of warm air inside causes a sharp temperature change, and the moisture instantly condenses, turning into an ice crust. Regular check sealing rubber bands will help avoid this problem.
Preparing to defrost the refrigerator
Before starting any manipulations, it is necessary to empty the chambers of food. Take care in advance about where you will put the freezer if you are planning a long shutdown. For short-term defrosting, you can use thermal bags or simply close the doors tightly to keep the cold in.
The next step is to completely disconnect the device from the power supply. Unplug the plug from the socket. You should not rely on the power button on the control panel, as some models Vestfrost may remain energized in standby mode. This requirement electrical safety cannot be ignored.
- 🧊 Remove all shelves, drawers and egg trays - it is more convenient to wash them separately in warm water.
- 💧 Prepare several large towels or rags to absorb water.
- 🪣 Find a flat tray or basin that can be placed under the drainage area.
- 🧼 Prepare a mild detergent and a finishing sponge.
Make sure there is enough free space around the refrigerator. You will need to move the unit away from the wall to gain access to the back panel and vents. This is especially important if you need to clean drainage hole.
☑️ Preparation checklist
Stages of manual defrosting
After the refrigerator is turned off, the longest stage begins - waiting. Leave cell doors open. The natural thawing process takes from 4 to 8 hours, depending on the amount of ice and the temperature in the room. It is not recommended to accelerate this process artificially.
It is strictly forbidden to use a hairdryer, hot water or chip off ice with a knife. A sudden temperature change can lead to cracks in the plastic box the evaporator, and the mechanical impact easily pierces thin tubes with refrigerant. Repairs in this case will be very expensive.
Water formed when the ice melts should flow freely into the drainage hole. If you see water standing in the chamber, it means the drain is clogged. Gently clean it with a soft syringe or a special brush, which is often included with Vestfrost.
What to do if the ice does not melt?
If more than 10 hours have passed and the ice block does not decrease, an ice plug may have formed deep in the channel. In this case, you can carefully (without force!) pour a little warm (not boiling water!) water into the drainage through a syringe without a needle.
While the chambers are empty, check the condition fan. In No Frost models it is located behind the rear panel. If, when turned on, it hums or rotates with difficulty, it may be jammed with ice or the bearings need lubrication.
Cleaning the internal surfaces and drainage
When all the ice has melted, you need to thoroughly rinse the internal surfaces. Use a weak solution of baking soda or a special refrigerator cleaner. Aggressive chemistry with chlorine or abrasive powders can damage antibacterial coating chambers.
Pay special attention to the groove at the bottom of the refrigerator compartment. This is where mucus and bacteria most often accumulate, causing an unpleasant odor. Wipe this area several times with a clean, damp cloth.
| Cleaning area | Agent | Tool | Frequency |
|---|---|---|---|
| Chamber walls | Soda solution | Soft sponge | Once every 6 months. |
| Seals | Warm water | A rag from microfiber | Once a month |
| Drainage | Warm water | Syringe/brush | When defrosting |
| Shelves (glass) | Glass cleaner | Paper towel | As it gets dirty |
Don't forget to wash and dry all removable elements: shelves, containers for vegetables, trays. Before installing them back, make sure that they are completely dry, otherwise the moisture will immediately turn into ice when turned on.
Starting and setting up after defrosting
Assemble the refrigerator in the reverse order. Place shelves and drawers in their proper places. Make sure nothing is blocking the free circulation of air. In models No Frost this is critical for uniform cooling.
Plug in the device. The alarm indicator on the control panel may come on or the display may flash - this is normal as the temperature inside is still high. Let the refrigerator run idle for 2-3 hours. During this time, it will reach the required temperature.
Check the operation of the compressor. It should turn on and off cyclically. If the motor hums continuously for more than 30 minutes without stopping, there may be a leak or malfunction of thermostat.
Only after the unit has been empty can you add food. Sharp loading with warm products will cause the compressor to work with overload, which will shorten its service life.
Frequent defrosting errors
The most common mistake is haste. Users try to speed up the process by placing bowls of boiling water inside or blowing with a hairdryer. This leads to deformation of the plastic and cracking evaporator. Repairing such damage is often not economically feasible.
The second mistake is ignoring drainage. Many people simply wipe the floor, forgetting to clean the drain hole. As a result, after a week or two, water will again begin to accumulate at the bottom of the chamber, requiring repeated defrosting.
- 🚫 Using sharp objects to chip ice.
- 🚫 Turning on the refrigerator with wet shelves and walls.
- 🚫 Loading food until the working level is set temperature.
- 🚫 Using aggressive solvents to clean plastic.
⚠️ Attention: If after defrosting the refrigerator makes unusual sounds (gurgling, whistling) or does not freeze, contact the service center immediately. It is possible that the electronics failed during defrosting.
Caring for equipment Vestfrost will ensure stable operation for many years. Regular maintenance takes less time than complex repairs.
Is it necessary to defrost a Vestfrost No Frost refrigerator?
Yes, even No Frost systems require preventative defrosting 1-2 times a year. This is necessary for hygiene, cleaning drainage and checking the condition of seals that are not cleaned automatically.
How long should a refrigerator defrost?
The optimal time for natural defrosting is from 4 to 8 hours. Do not use artificial heating to avoid damaging the plastic parts and tubes of the evaporator.
What to do if an unpleasant odor appears after defrosting?
It is necessary to re-rinse all surfaces with a solution of soda or vinegar. Pay special attention to the drainage hole - this is where the source of the odor often lies.
Is it possible to turn on the refrigerator immediately after washing?
Yes, but make sure that all surfaces and removable elements are completely dry. Turning on a wet appliance can lead to the formation of an ice crust and increased load on the compressor.
