How to defrost the Dexp refrigerator: a complete guide with tips masters

Refrigerators Dexp are popular due to the combination of affordable prices and modern technologies, but even the most reliable models require regular defrosting. If your device is covered with a thick layer of ice, is working intermittently, or it’s simply time for routine cleaning, this article will help you carry out the procedure quickly and safely. We will analyze all stages: from preparation to final cleaning, we will take into account the features of different models Dexp (including Dexp HF-100, HF-140 and series c No Frost), and also tell you how to avoid typical mistakes that lead to breakdowns.

It is important to understand that defrosting is not only a hygienic procedure, but also the prevention of serious malfunctions. Ice thicker than 5–7 mm increases the load on the compressor, increases energy consumption by 15–20% and can cause thermostat failure. In this manual you will find current advice for 2026, taking into account the latest manufacturer recommendations and the experience of service centers.

Preparing for defrosting: what needs to be done before turning off the refrigerator

The first step is proper preparation. Its speed and safety for equipment depends on how carefully you organize the process. Start with choosing the time: ideally, if defrosting occurs on a cool day (for example, morning or evening), when the temperature in the room does not exceed 20–22°C. This will reduce the load on the compressor when turned on again.

Gather the necessary tools in advance:

• 🧊 Plastic containers or basins for collecting melt water (do not use metal ones - they can scratch the shelves!).
• 🧽 Soft sponges, microfiber rags and special wipes for equipment (without abrasive particles).
• 🧴 Refrigerator cleaner (for example, Topperr, Sano) or baking soda solution (2 tablespoons per 1 liter of water).
• 🔌 Extension cord with grounding (if the outlet is in an inconvenient location place).
• 📦 Thermal bag or cooling batteries for temporary storage of perishable products.

Pay special attention to products: divide them into 3 categories:

1. Those that can be left at room temperature for 2-3 hours (canned food, sauces, some vegetables).
2. Foods that require refrigeration (dairy, meat, fish) - it is better to put them in a thermal bag with ice.
3. Frozen foods that will not have time to thaw during defrosting (if the procedure takes less than 4 hours).

Step-by-step instructions: how to defrost a Dexp refrigerator without the risk of breakage

Now let's move on to the main process. Depending on the model Dexp (with a system No Frost or drip defrosting), the algorithm may differ slightly, but the general scheme remains the same. Let's consider a universal method suitable for most household refrigerators of this brand.

Step 1. Turn off the power

Unplug the plug from the socket - never defrost the refrigerator by simply turning it off with the button! This may cause the electronic module to malfunction. If your model is equipped with a display (for example Dexp HF-160W), wait until it goes out - this is a signal that the power is completely turned off.

Step 2. Accelerating the melting of ice

Natural defrosting can take from 4 to 12 hours, but there are ways to speed up the process without harm to equipment:

• 💨 Place a fan in front of the open refrigerator door at minimum speed (distance - at least 50 cm).
• 🍳 Place a pan with hot water inside (temperature not above 60–70°C, after placing a towel under it.
• 🧊 Use a plastic scraper (not metal!) to carefully remove the top layer of ice.

Step 3. Removing melt water

As the ice melts, the water will flow into a special tray (usually located at the back of the refrigerator). In models Dexp with the system No Frost moisture can also accumulate inside the chamber - watch for this and wipe the surfaces in a timely manner. Do not allow water to get into compressor or drain hole as this may result in a short circuit or blockage.

Step 4. Cleaning and disinfection

After complete removal of ice, proceed to washing. Use warm soapy water or a specialized product. Pay special attention to:

• 🔍 The door seal (wipe it with a soda solution - this will prevent mold from appearing).
• 🕳️ The drainage hole (clean it with a cotton swab dipped in alcohol).
• 🧊 The back wall of the freezer (dirt and bacteria often accumulate there).

What to do if the water does not drain through the drainage hole?

If after defrosting water remains at the bottom of the refrigerator, most likely the drainage hole is clogged. For cleaning, use a special brush (included with some models Dexp) or soft wire. After cleaning, rinse the hole with water and citric acid (1 teaspoon per glass of water).

Features of defrosting Dexp refrigerators with the No Frost system

Many users mistakenly believe that refrigerators Dexp with technology No Frost do not require defrosting. In fact, even such models need to be defrosted 1-2 times a year, but the process takes much less time (1-2 hours) and comes down to general cleaning.

Here are the key differences for No Frost:

In models Dexp with No Frost (for example, HF-180NF or HF-220NF) pay special attention to the ventilation grilles. They can only be cleaned with a dry soft brush or with a vacuum cleaner at minimum power. Never wash them with water or use sharp objects - this may damage the air circulation system.

Typical mistakes when defrosting and how to avoid them

Even experienced users sometimes make mistakes that lead to breakdowns or shorten the life of the refrigerator. Here are the most common of them and ways to prevent them:

1. Using sharp objects to remove ice

Knives, forks or metal scrapers can damage plastic parts and refrigerant lines. If the ice does not come off, use plastic spatula or a wooden spoon. To simplify the task, you can apply a salt solution to the ice (1 tablespoon per glass of water) - this will speed up the melting.

2. Turning on the refrigerator immediately after washing

After wet cleaning, allow all surfaces to dry completely (at least 30–40 minutes). When switched on, moisture remaining on the walls may freeze and form ice again. This is especially true for models with electronic control (for example, Dexp HF-200E), where condensation can cause corrosion of the contacts.

3. Ignoring the rubber seal

The door rubber is one of the most vulnerable points. If it is dirty or deformed, the refrigerator will work overload and ice will build up faster. After washing, lubricate the rubber band with with silicone grease or glycerin - this will extend its service life.

4. Defrosting in a hot room

If the temperature in the room is higher 25°C, it will be more difficult for the compressor to reach the desired temperature after turning on. This may lead to motor overheating automatic shutdowns. In the summer, defrost the refrigerator Dexp early morning or late evening.

5. Neglecting the drainage hole

A clogged hole is one of the main reasons for the accumulation of water at the bottom of the refrigerator. To clean it, use a syringe with warm water or a special brush. In models Dexp the drainage hole is usually located on the back wall above the condensate collection tray.

⚠️ Attention: If after defrosting the refrigerator Dexp does not turn on or makes unusual sounds (for example, humming without starting the compressor), immediately disconnect it from the network and call masters This may indicate a breakdown of the motor winding or freon leak.

How often do you need to defrost a Dexp refrigerator: manufacturer's recommendations

The frequency of defrosting depends on model, intensity of use and operating conditions. The manufacturer Dexp gives the following recommendations (relevant for most models produced in 2020–2026):

• 🧊 Refrigerators with drip system (for example, Dexp HF-100, HF-120) - once every 3-4 months or when thick ice forms more 5 mm.
• ❄️ Models with No Frost (series NF) - once every 6-12 months (depending on the humidity in the room).
• ⚡ Refrigerators with manual defrosting (old models) - once every 1-2 months.

However, there are factors that require more frequent defrosting:

• 🌡️ High room temperature (above 25°C).
• 🚪 Frequent opening of the door (more than 20 times a day).
• 💦 High humidity (for example, if the refrigerator is located next to the stove or sink).
• 🍲 Storing liquid dishes without lids (soups, compotes).

If you notice that ice forms too quickly (for example, in 1-2 weeks), this may indicate a malfunction:

• 🔧 The door does not fit tightly (check the seal).
• 🕯️ Failure of the thermostat or sensor temperature.
• ⚙️ Clogged capillary tube (professional cleaning required).

⚠️ Attention: The instructions for some models Dexp (for example, HF-160W) indicate that defrosting is required only when ice formation. However, in practice, even in the absence of visible ice, bacteria and unpleasant odors accumulate inside. We recommend carrying out preventive cleaning at least once every 6 months.

Care after defrosting: how to extend the life of the Dexp refrigerator

Proper care after defrosting is no less important than the procedure itself. longer:

1. Checking the temperature mode

After turning on, set the optimal parameters:

• 🥶 Refrigerator compartment: +4°C (for most products).
• ❄️ Freezer chamber: -18°C (standard for long-term storage).

In models Dexp with electronic control (for example, HF-200E), the temperature can be set with an accuracy of 1°C through the panel on the door or touch display.

2. Organization of products

Place products so as to ensure free air circulation:

• 🥦 Vegetables and fruits - in special containers (humidity 80–90%).
• 🥩 Meat and fish - on the lower shelves (the coldest zone).
• 🥛 Dairy products - on the middle shelves.
• 🍞 Bread and pastries - in the upper compartments or special boxes.

3. Prevention of odors

To avoid unpleasant ones. odors:

• 🍋 Wipe the shelves with a solution of citric acid (1 tablespoon per 1 liter of water) once a month.
• ☕ Place an open pack of soda or a special odor absorber on one of the shelves (for example, Arm & Hammer).
• 🧅 Store onion and garlic peelings in airtight containers.

4. Humidity control

Excess humidity is the main reason for the rapid formation of ice. To reduce it:

• 💧 Wipe off condensation from food before placing it in the refrigerator.
• 🍲 Cover liquid dishes with lids or cling film.
• 🌬️ Regularly ventilate the room where the refrigerator is located.

What to do if the Dexp refrigerator does not turn on after defrosting

Sometimes after defrosting the refrigerator refuses to turn on. Don’t panic - in 80% of cases the problem is solved without calling a technician. Here is the algorithm:

1. Check the power supply.

• 🔌 Make sure that the plug is firmly inserted into the socket.
• 💡 Check if the socket is working (connect another device).
• ⚡ If the circuit breaker on the panel works, turn it on again.

2. Give time. "rest"

After defrosting, the compressor needs 10-15 minutes to normalize the refrigerant pressure. If the refrigerator does not turn on immediately, wait and try again after 20 minutes.

3. Check the settings

In models with electronic control (for example, Dexp HF-180E) after turning off the power, the settings may be reset. Make sure that:

• 🔄 The mode is not set to Off or Demo.
• 🌡️ The temperature is set correctly (not 0°C or Min).
• 🔔 The error indicator does not light up (for example, E1, E2 —see instructions).

4. Diagnosis of faults

If the refrigerator still does not work, possible reasons:

⚠️ Attention: If the refrigerator Dexp emit hissing sound or oil stains appear on the back wall, immediately unplug it. These are signs! further operation is dangerous. refrigerant leaks, and further operation is dangerous.
