Modern brand refrigerators DEXP, despite advanced technologies, require regular maintenance to maintain efficient operation. Even if you own a model with the system No Frost, ignoring scheduled maintenance can lead to reduced compressor performance and the appearance of foreign odors. Many users mistakenly believe that the absence of ice on the back wall completely frees them from the need to defrost equipment, but this is not entirely true.
The process of complete defrosting is necessary not only to remove ice, but also to ensure high-quality sanitary treatment internal chambers. Accumulated dust on the evaporator, food residues and condensation over time create an ideal environment for the growth of bacteria. In order for the equipment DEXP to serve for many years without breakdowns, it is important to follow a clear algorithm of actions described in this article.
In this guide we will analyze the differences in servicing various types of refrigeration units and answer the question of how often this procedure should be carried out. The right approach will avoid emergency situations and preserve the freshness of your products.
Features of defrosting systems in DEXP refrigerators
Before starting any manipulations, you must determine exactly which defrosting system is installed in your model. Refrigerators DEXP can be equipped with both classic drip systemand technology No Frost (or Full No Frost). The frequency of the procedure and the method of ice removal directly depend on this.
In models with a drip system, moisture settles on the back wall, freezes, and then thaws during pauses in the operation of the compressor, flowing into a special tray. Here, ice can only form if there is a malfunction or very high humidity in the room. Units with No Frost have a hidden evaporator and a fan that circulates dry cold air, preventing the formation of frost on food.
⚠️ Attention: An attempt to mechanically break off the ice with a knife or screwdriver in any type of DEXP refrigerator will lead to depressurization of the cooling system. Repair in this case will not be economically feasible.
Despite the automation of processes, both types of systems require periodic complete shutdown from the network. This is necessary in order to allow moisture to evaporate in hard-to-reach places where ventilation is limited, and to carry out deep cleaning of contaminants that are not removed during operation.
Preparation for defrosting: algorithm of actions
The beginning of the process requires careful preparation to minimize the risks of food spoilage and damage to the floor covering. The first step should always be turning off the power supply. Unplug the cord from the outlet or turn off the circuit breaker on the panel if access to the outlet is difficult.
Next, you need to empty the cameras of their contents. All perishable foods should be moved to a cool place, use thermal bags or, in winter, taken out to the balcony (if the temperature there is not lower than +5°C for the refrigerator). For the freezer, it is better to prepare containers with ice to slow down the melting.
It is important to prepare a place to collect melt water. Although the design DEXP has drainage systems, if there is excessive thawing, they may not be able to cope with the flow, especially if the hole is clogged with debris.
☑️ Preparing for defrosting
Remove all removable elements: glass shelves, plastic containers, bottle holders and grilles. They should be washed separately with warm water and a mild detergent. This will provide access to all internal surfaces and corners of the chamber.
Defrosting process: natural and accelerated melting
The safest and recommended by the manufacturer DEXP method is natural melting of ice. Leave the refrigerator and freezer doors open. Depending on the thickness of the ice and the room temperature, this process can take from 3 to 24 hours. You should not rush things by using aggressive methods.
If time is running out, you can use accelerated but safe methods. It is allowed to install containers with hot water (but not boiling water!) in the chambers so that warm steam accelerates the melting. You can also direct a flow of warm (not hot!) air from a fan or hair dryer, holding the device at a distance of at least 30-40 cm from the plastic.
⚠️ Attention: Using a hair dryer requires caution. Direct the air strictly at the ice, avoiding prolonged exposure to plastic seals and decorative panels, as they can become deformed from overheating.
It is strictly forbidden to use sharp objects, hammers, or pour boiling water directly onto frozen areas to chip ice. A sudden temperature change can cause cracks in the heat exchanger or damage the internal plastic lining of the chamber.
During the melting process, make sure that water does not leak outside the refrigerator. Place thick towels under the door or install a low fabric edge. If the condensate tray overflows, carefully remove the water using a bulb or syringe.
Cleaning and disinfecting the internal chambers
After Once all the ice has melted and the water has been removed, the cleaning stage begins. The internal surfaces of refrigerators DEXP are made of high-quality plastic, which is sensitive to aggressive chemicals. To wash, use a soft sponge and a weak solution of baking soda or a special product for washing refrigerators.
Pay special attention to the rubber seals on the doors. Dirt and mold often accumulate in the folds, which disrupts the seal. Wipe them with a cotton swab dipped in a solution of vinegar or citric acid to remove plaque and restore elasticity. sealing rubber bands on the doors. Dirt and mold often accumulate in the folds, which disrupts the seal. Wipe them with a cotton swab dipped in a solution of vinegar or citric acid to remove plaque and restore elasticity.
Be sure to clean the drainage hole located on the back wall of the refrigerator compartment. It often becomes clogged with crumbs and slime, causing puddles to appear under your vegetable drawers. For cleaning, use a special flexible brush or cotton swab.
| Cleaning area | Recommended product | Treatment frequency | Tool |
|---|---|---|---|
| Internal walls | Soda solution (1 tbsp per 1 liter of water) | Each defrosting | Soft sponge |
| Door seals | Vinegar or lemon solution acid | Once every 3-4 months | Cotton swab/rag |
| Drainage hole | Warm water | Once every six months | Brush or stick |
| Ventilation grilles | Dry soft brush | Once a year | Brush |
After During wet cleaning, all surfaces must be wiped dry with a clean cloth. Remaining moisture can quickly turn into ice when turned on, especially in the freezer.
Drying and first start after inactivity
A critical step that is often ignored is complete drying. Before connecting to the network, the refrigerator DEXP must stand with the doors open for at least 2-3 hours. This is necessary to evaporate micro-moisture from the thermal insulation layer and electrical contacts.
If you turn on a wet unit, a short circuit or incorrect operation of the temperature sensors may occur. Make sure that there is no water left in the recesses and joints of the panels. Only after you are completely sure of dryness can you begin assembly.
Why can’t you turn on the refrigerator immediately after washing?
Condensation may remain inside the electrical circuit and on the contacts of the compressor. Turning on a wet device can lead to failure of the control board or breakdown of the housing, which is life-threatening.
Install all shelves and drawers in their places. Make sure they are securely fastened. You can now plug the power cord into a power outlet. Let the refrigerator run idle (without food) for 1-2 hours so that it reaches the required temperature and turns off automatically.
After the compressor turns off and the signal sounds (if the model is equipped with a display), you can add food. Do not overload the chambers with a large volume of warm food at once - this will put extra stress on the compressor. Defrosting frequency and typical mistakes. Owners often ask how often they need to defrost equipment. For models compressor.
Defrosting frequency and typical errors
Owners often ask how often they need to defrost their appliances. For models DEXP with a drip system, the optimal frequency is 2 times a year. Units with No Frost require complete defrosting and cleaning less often - once a year is enough, unless there is an emergency power outage.
One of the main mistakes is ignoring the tilt of the body. The refrigerator should be strictly level or with a minimum tilt back so that the water flows by gravity into the drainage. Check the feet and adjust them if necessary.
Also, users often forget to clean the rear condenser grille (the black radiator at the back). Dust on it impairs heat transfer, causing the compressor to wear out. Vacuum or gently brush this unit during general cleaning.
Following these simple operating rules will allow your refrigerator DEXP to keep food fresh for many years. Regular maintenance takes a minimum of time, but prevents costly repairs and loss of food.
Frequently asked questions (FAQ)
Is it possible to defrost a DEXP refrigerator without unplugging it?
No, this is strictly prohibited. Defrosting is only possible when the power supply is completely disconnected. A running compressor will try to compensate for the heat from the melting ice, causing it to become overloaded and possibly fail. In addition, getting water on working electrical elements is dangerous.
What to do if the refrigerator does not freeze after defrosting?
Let it stand turned off for a few more hours. There may be liquid refrigerant left in the system or moisture in the contacts. If after 4-5 hours of idling operation the temperature does not drop and the compressor is humming, contact a service center.
Do you need to lubricate the rubber seals after defrosting?
Yes, this will extend their service life. Use special silicone for rubber seals or, as a last resort, glycerin. This will prevent the rubber from cracking and ensure a tight fit of the door.
How to understand that the drainage hole is clogged?
If water collects under the bottom vegetable drawer after defrosting or in normal mode, it means the drainage is clogged. It is necessary to clean it with a brush or soft wire wrapped in cotton wool.
