Modern household appliances require a careful approach immediately after purchase, and setting up a DEXP refrigerator is no exception. Correct initial configuration directly affects the service life of the compressor and the quality of food preservation. Many users mistakenly believe that it is enough to simply plug the device into the network, but ignoring the preparation steps can lead to increased energy consumption or even breakdown of the unit in the future.
Budget segment brands, which include DEXPoften use time-tested technologies, but their control interfaces may be not obvious to beginners. In this article we will analyze in detail the process of setting temperature conditions, activating special functions and diagnosing possible problems. A competent approach to initial startup will ensure stable operation of the equipment for many years.
Before you begin setting up the control panels, you must make sure that all transportation and installation conditions are met. The refrigerator must be allowed to sit after delivery, especially if it was transported in a lying position. The oil in the compressor must drain back into the crankcase, otherwise water hammer can damage the engine in the first minutes of operation.
⚠️ Attention: If the refrigerator was transported on its side, the minimum settling time before turning on should be at least 12 hours, or better yet, a full day.
The setup process begins with choosing the right place. The unit should not be placed close to a wall or heating devices. For effective heat exchange capacitor free air circulation is required. Failure to maintain clearances leads to overheating and increased operating time of the compressor, which is especially critical for models with inverter motors.
Primary preparation and level setting
The first step after unpacking is to remove all transport locks. Interior shelves and drawers may be secured with tape or foam inserts that need to be removed. Also remove the protective film from the external and internal surfaces to avoid the appearance of foreign odors during the first cooling.
A critically important step is to align the case horizontally. Incorrect tilting may result in the door not closing tightly on its own, which will compromise the seal of the chamber. To adjust, use the front support legs, rotating them clockwise or counterclockwise.
- 📏 Use a building level to check the horizontal position of the top panel.
- 🚪 Check the angle of inclination: the door should tilt slightly back for a self-closing effect.
- 🔧 Adjust the legs with a key or manually until the level bubbles are in the center.
- 💨 Leave a gap of at least 5-7 cm from the back wall to the furniture for ventilation.
After installation, check the tightness of the seals. If the door is skewed, the magnetic tape will not provide a seal and will begin to build up inside ice coat. In some models DEXP the position of the doors can be adjusted by reversing the hinges, but this is rarely required and only in case of obvious assembly defects.
☑️ Primary preparation of the refrigerator
Adjusting the temperature mode
The main task of the user is to set the optimal temperature for the refrigerator and freezer compartments. In models DEXP the control can be mechanical (thermostat with numbers) or electronic (display and touch buttons). The numbers on the mechanical regulator do not indicate degrees, but cooling intensity.
For mechanical models, the optimal position of the regulator is number 2 or 3. Setting the maximum value (usually 5 or 7) forces the compressor to work without interruption, which leads to freezing of the rear wall and excessive energy consumption. Electronic panels allow you to set the exact temperature, for example +4°C for the main chamber.
⚠️ Attention: Do not fill an empty refrigerator with food immediately after turning it on. Let the equipment run idle for 2-3 hours to stabilize the temperature background.
It is recommended to maintain a temperature of -18°C in the freezer. This value is the standard for long-term storage of meat and fish. If you plan to freeze a large amount of fresh food, use the Super Freeze (Super Freeze) mode, which forcibly lowers the temperature to -24°C.
Remember that frequently opening the door or loading warm products will upset the settings. The system will have to compensate for the heat by increasing the operating time of the compressor. Follow the indicators on the panel: a flashing symbol often indicates that the inside of the chamber is warmer than the established norm.
Managing the electronic display and functions
Many modern models DEXP are equipped with an external display. The interface may be blocked from accidental clicks, especially if there are children in the house. Unlocking usually requires a long press (3-5 seconds) on a button with a picture of a lock or a key combination.
Let's look at the main modes available on the control panel. The function Eco Mode switches the refrigerator into an economical operating mode, slightly increasing the temperature in the chambers to a safe but energy-saving level. The Vacation (Vacation) mode turns off the refrigerator compartment, leaving the freezer working, which prevents the appearance of mold during a long absence of owners.
Secret reset combination
In some DEXP models with electronic control, a complete reset of settings (Reset) is performed by simultaneously pressing the temperature control buttons refrigerator and freezer compartments for 10 seconds. This can help if the electronics freeze.
Error indications are displayed on the screen in the form of alphanumeric codes. For example, a flashing letter F often indicates a malfunction of the freezer sensor, and H - a high temperature. Understanding these signals helps you quickly diagnose the problem without calling a technician.
| Indicator/Code | Meaning | User action |
|---|---|---|
| 🔔 Sound/Flashing | The door is open or loose closed | Check the closing tightness, remove obstacles |
| ❄️ Snowflake | Super Freeze mode is activated | Turn off after 24 hours manually or wait for auto shutdown |
| 🔒 Lock | Lock the control panel | Press and hold the button locks for 3 seconds |
| ⚠️ Alarm | Temperature is above normal | Check loading, closure tightness, fan operation |
If the display goes out or behaves incorrectly, try rebooting the device. Unplug the refrigerator for 10-15 minutes, then turn it on again. This action resets temporary errors electronic module control.
Features of the No Frost and defrost system
Technology No Frost (Without frost) relieves the user of the need to defrost the refrigerator manually, but requires a correct understanding of the principles of its operation. In such models, cold air circulates through the chambers using a fan, uniformly cooling the food. However, this can lead to drying uncovered food.
It is important to understand that the No Frost system periodically turns on the heating element to defrost the evaporator, which is hidden behind the back wall. The water flows into a special pan above the compressor and evaporates. If you hear periodic gurgling or cracking sounds, this is normal operation and not a sign of a breakdown.
- 🥩 Pack food: opened food quickly loses moisture in dry air currents.
- 💨 Do not block the ventilation openings: the cold must circulate freely.
- 🧹 Once a year, check the drainage hole on the back wall for blockages.
Despite the name "frost-free", a minimum amount of frost in the corners or on the seals is allowed and considered the norm. The main thing is that ice build-up does not interfere with closing the door. If ice builds up quickly, check the tightness of the sealing rubber sealing rubber.
⚠️ Attention: Never try to speed up defrosting with a hairdryer or hot water. A sudden change in temperature can lead to cracks in the plastic inner box or damage to the freon tubes.
Energy efficiency and economical operation
The refrigerator is one of the few appliances that operates 24 hours a day, so its energy consumption significantly affects electricity bills. Models DEXP usually have an energy consumption class A+ or higher, but real savings depend on operating conditions. Installing the device next to a battery or in direct sunlight causes the compressor to wear out.
The load on the chambers also plays a role. An empty refrigerator loses cold faster when the door is opened, as cold air is replaced by warm air. The optimal load is about 70% of the volume. In the freezer, on the contrary, the presence of frozen foods helps to maintain cold, working as a cold accumulator.
Regularly check the condition of the seals. If the rubber has lost its elasticity or is dirty, the cold will escape. Wipe the seals with a soft cloth and soapy water. To extend the life of the rubber, you can lubricate it with a special product or silicone grease every six months.
Diagnostics and noise
During operation, users may encounter various sounds. The hum of the compressor, the noise of flowing fluid (freon) and the clicking of the relay are the normal sounds of the refrigeration circuit. However, strong vibrations or knocking may indicate installation problems or internal problems.
If the refrigerator vibrates, make sure it is not touching the walls of the kitchen unit. Sometimes vibration is transmitted to the shelves if they are not fully inserted into the grooves. Check that food is not lying close to the back wall - this can cause rattling in cooling areas.
Why is the DEXP refrigerator humming loudly?
Loud humming can be caused by several reasons: incorrect installation (not level), compressor tubes touching each other or the housing, or compressor wear. If the humming appears suddenly and is accompanied by heating of the case, contact service.
What to do if the operation indicator does not light up?
The absence of indication may mean a lack of power (check the socket and cord), a burnt-out lamp (if only the light is not on) or a malfunction of the control board. Try plugging the device into a different outlet.
How often do you need to defrost DEXP No Frost?
The No Frost system does not need to be defrosted to remove ice, but it is recommended to carry out preventive washing and defrosting at least 1-2 times a year to maintain hygiene and clean hard-to-reach places.
Why does condensation form on the shelves?
Condensation may appear due to frequent opening of the door, storing liquids in open containers, or clogged drainage holes. Check to see if the drain hole is clogged with crumbs or ice.
Compliance with operating rules and a timely response to changes in the operation of the device will avoid costly repairs. If you notice a burning smell, sparking or complete loss of cold, immediately unplug the device and contact a specialist. Self-repair refrigeration circuit without special equipment and skills is prohibited.
