Modern household appliances brand DEXP, despite the presence of advanced automatic defrosting systems, periodically requires user intervention. Even models marked No Frost, which are positioned as not requiring defrosting, require preventive cleaning and disinfection. Ignoring this process can lead to a decrease in heat transfer efficiency, the appearance of unpleasant odors and an increase in energy consumption.
Many owners mistakenly believe that if ice does not form on the back wall, then there is no need to wash the unit. However, static electricity attracts dust, and microscopic food particles settle on the evaporator, creating an ideal environment for bacteria. Therefore, regular maintenance is necessary for any equipment, regardless of the type of cooling system.
In this guide we will analyze in detail the algorithm of actions for various models of refrigerators DEXP. You will learn how to safely turn off the device, where to put food, how to wash the internal surfaces and how to quickly return the device to operating mode without the risk of damaging the compressor or plastic elements.
⚠️ Attention: Before starting any work, make sure that you have unplugged the plug from the socket. Working with live electrical appliances during washing is strictly prohibited by safety rules.
Preparing for the defrosting process
The first step is to clear the internal space of food. If you plan to defrost the refrigerator DEXP in winter, this stage will be easier, since the food can be temporarily taken out onto the balcony. In the warm season, you will have to be smart and use thermal bags or tightly stuffed blankets to keep the cold in.
It is necessary to completely remove all shelves, vegetable drawers, egg containers and bottle holders. Plastic elements become brittle at low temperatures, so you need to remove them carefully, without sudden movements. Glass shelves also require care, especially if they are warm and you plan to wash them with cool water.
Prepare cleaning supplies in advance. You will need soft, lint-free sponges and clean cotton rags. Abrasive materials, such as hard brushes or steel wool, should not be used - they can scratch the plastic or protective coating of the metal.
☑️ Preparing for defrosting
Natural thawing of ice
After the equipment is disconnected from the network, the process of natural thawing begins. Depending on the thickness of the ice crust and the room temperature, this stage can take from 3 to 10 hours. Forcefully speed up the process using a hairdryer or hot water is strictly not recommended by DEXP manufacturersas a sharp temperature change can deform the plastic case or damage the evaporator tubes.
The ice will melt and the water will begin to flow into the drainage chute. It is important to ensure that water does not overflow the edge of the gutter and flow onto the floor. To do this, a rag is often placed under the refrigerator door, and a flat tray is installed in the freezer, if the design allows.
If the ice cap is very thick, you can leave the doors open for air circulation. However, make sure that plastic parts are not exposed to direct sunlight, as ultraviolet destroys the structure of the polymer, making it brittle.
- 🧊 Leave the doors wide open for better air circulation.
- 🧽 Place thick towels on the floor in front of the refrigerator.
- ⏳ Be patient - the safest natural process for equipment.
- 💧 Check to see if the drainage hole is clogged.
As the ice melts, the water may contain contaminants, so periodically wipe the internal surfaces with a dry cloth. This will help remove softened ice and dirt faster, without waiting for all the moisture to completely drain.
Cleaning and disinfection of the internal chambers
When all the ice has melted, the thorough washing stage begins. For refrigerators DEXP it is best to use specialized products for household appliances or a weak solution of baking soda. Chlorine-containing aggressive chemicals can damage seals and leave a persistent odor, which will then take a long time to dissipate.
Pay special attention to the rubber seal on the door. Mold and dirt often accumulate in its folds. Wipe the seal with a cotton swab dipped in vinegar solution or a special spray. This will extend the life of the rubber and ensure the seal of the chamber.
What should not be used to clean the refrigerator?
Do not use acetone, gasoline, abrasive powders or solvents. They can dissolve plastic or remove protective layers from metal surfaces. Also avoid hot water above 40 degrees.
After wet cleaning, all surfaces must be wiped dry with a clean cloth. Residual moisture in corners or joints can cause an unpleasant odor during subsequent use. Allow the chambers to dry completely, leaving the doors open for another 15–20 minutes.
Care for the ventilation and drainage system
In models DEXP with a system No Frost the condition of the drainage hole is critically important. It is located on the back wall of the freezer or refrigerator. It is through it that the condensate goes into a special container above the compressor, where it evaporates.
If the hole is clogged with crumbs or ice, water begins to accumulate at the bottom of the chamber or flow out. To clean, use a special flexible brush (often included) or a soft wire wrapped in cloth. You must act carefully so as not to pierce the canal wall.
| Element | Cleaning frequency | Tool | Risk of ignoring |
|---|---|---|---|
| Drainage hole | Each defrosting | Brush or cotton swab | Puddle on the floor, ice |
| Rubber seal | Once every 3 months | Wet napkin, vinegar | Loss of tightness, ice |
| Ventilation grilles | Every six months | Vacuum cleaner, soft brush | Noise, poor cooling |
| Rear wall (condenser) | Once a year | Vacuum cleaner (with caution) | Overheating of the compressor |
It is also worth inspecting the ventilation holes inside cameras They should not be blocked by food or packaging. Impaired air circulation leads to uneven cooling and the formation of local icing zones.
Drying and assembling the refrigerator
Before assembling the structure back, make sure that all parts are absolutely dry. Damp shelves or drawers can freeze to the walls or to each other, making them difficult to remove in the future. The plastic should be at room temperature.
Start assembly by installing the largest elements - glass shelves and large containers. Make sure that they fit into their guides until they click or securely stop. Fragile glass surfaces should not touch metal walls without rubber gaskets.
After installing all internal elements, close the doors and turn on the refrigerator. Let it run idle for at least 2-3 hours. During this time, the unit will reach the required temperature, and the automation will return to normal operation.
⚠️ Attention: Do not load food into a warm refrigerator. The compressor will work hard trying to cool warm objects, which can shorten the life of the motor.
Frequent defrosting mistakes
One of the most common mistakes is using a knife or screwdriver to chip the ice. In refrigerators DEXP, as in other modern models, the evaporator tubes are often mounted directly into the wall of the case. One awkward movement can break through the wall and release the coolant. Repair in this case will be difficult and expensive.
Another mistake is turning on the device immediately after washing, without waiting for the electrical contacts to dry and the moisture from hard-to-reach places to completely evaporate. This can lead to a short circuit.
Also, do not wash the refrigerator with the doors closed using large amounts of water. Water can flow into the space between the inner and outer casing, causing corrosion of the metal and damage to the insulating material.
- 🚫 Do not pour water directly onto the walls and shelves.
- 🚫 Do not use steam cleaners inside the chambers.
- 🚫 Do not leave the refrigerator is turned off with the doors closed for a long time (mold may appear).
- 🚫 Do not place hot objects on cold shelves immediately after assembly.
Specifics of DEXP models with No Frost
Refrigerator owners DEXP with the system No Frost they often wonder: do they need to be defrosted? Technically, these models are equipped with defrosting heating elements that automatically remove frost from the evaporator. However, once a year (or at least once every two years) it is necessary to completely defrost and wash it.
This is due to the fact that the ventilation system circulates air throughout the entire volume of the chamber, spreading odors and bacteria. In addition, the drainage system may become clogged with dust that comes with food. Preventive cleaning prolongs the life of the fan and sensors.
When servicing such models, it is important not to flood the air ducts located on the rear wall with water. Clean only with a cloth, avoiding direct contact with the ventilation holes.
How long does it take to completely defrost a DEXP refrigerator?
The time depends on the temperature in the room and the thickness of the ice. Typically the process takes from 4 to 8 hours. Do not try to artificially speed up the process with a hairdryer, this may damage the plastic.
Is it possible to wash a DEXP refrigerator with a soap solution?
It is not recommended to use ordinary laundry soap, as it leaves a residue and odor that is difficult to wash off. It is better to use special products or a soda solution (1 tablespoon per liter of water).
What to do if the refrigerator does not freeze after defrosting?
Wait 3-4 hours. If the problem persists, check that the doors are closed tightly and that the temperature setting is not off. If the cold does not appear after 24 hours, contact service.
Does the seal need to be lubricated with silicone?
Yes, once every six months it is recommended to wipe the rubber seal with glycerin or a special silicone lubricant. This will preserve the elasticity of the rubber and improve the fit of the door.
