Dimroth refrigerator: operating instructions and secrets of effective use

Refrigerators Dimetra (or Dimrotaas they are often called in Russia) are equipment with a unique cooling system, combining German technologies and adaptation to Russian conditions. They are known for their energy efficiency, quiet operation and long service life, but require the right approach to operation. Unlike standard models, refrigerators of this brand are often equipped double-circuit cooling systemwith inverter compressors and a freshness zone with separate adjustment. However, even such advanced equipment can fail if you ignore the basic rules of use.

In this article we will examine not only the obvious points (how to adjust the temperature or defrost), but also hidden functionsthat are not written about in standard instructions. For example, how to properly distribute food into zones, why you can’t put hot dishes even in the “freshness zone,” and what to do if the refrigerator Dimetra starts making uncharacteristic sounds. We will pay special attention to typical errors that reduce the service life of equipment by 30-40%.

1. The structure of a Dimroth refrigerator: what’s inside and how it works

Refrigerators Dimetra belong to the premium segment, and their design differs from budget models. Main elements of the system:

• 🔹 Inverter compressor —operates without sudden power surges, which reduces power consumption and noise. Models Dimetra ProLine use a two-stage compressor for more precise temperature control.
• 🔹 Double-circuit cooling —the freezer and refrigerator compartments are cooled independently, which prevents mixing of odors and over-drying of food.
• 🔹 Freshness zone FreshZone —a separate compartment with temperature 0...+3°C and adjustable humidity (models Dimetra Premium have a sensor Humidity Control).
• 🔹 System NoFrost or FrostFree —depending on the model. The first completely eliminates the formation of frost, the second requires defrosting 1-2 times a year.

Important feature: in refrigerators Dimetra they are often used electronic control with a touch panel, rather than mechanical regulators. This allows you to more accurately adjust the temperature, but requires careful handling - the sensors are sensitive to. moisture and grease. For example, in the model Dimetra DF-520 the control panel is located inside the chamber, which protects it from accidental pressing, but complicates cleaning.

⚠️ Attention: If your refrigerator Dimetra was manufactured before 2020, it can be installed capillary thermostat instead of an electronic sensor. This affects the accuracy of temperature maintenance - the spread can reach ±2°C instead of standard ±0.5°C in new models.

Another one nuance - the ventilation system. In refrigerators with NoFrost air circulates forcibly, so you cannot block the ventilation holes with food. In models with FrostFree (for example, Dimetra Classic), ventilation is passive, but regular defrosting is required to avoid ice on the back wall.

2. Optimal temperature settings: how to set and check

The manufacturer recommends the following temperature conditions for refrigerators Dimetra:

• 🥶 Refrigerator compartment: +4...+5°C (for the freshness zone - 0...+3°C).
• ❄️ Freezer compartment: -18°C (for long-term storage) or -24°C (for quick freezing).

However, these values may vary depending on:

• 📦 Chamber load — if the refrigerator is less than 30% full, the temperature may “walk.”
• 🌡️ Room temperatures —at +30°C in the kitchen the compressor will work more intensely.
• 🔄 Door opening frequency —each opening increases the temperature by 1-2°C.

To adjust the temperature:

1. On models with a touch panel, press Menu → Temperature → Refrigerator compartment (or Morozilka).
2. In mechanical models (for example, Dimetra Retro) turn the knob on the back wall: 1 —minimum cold, 5 —maximum.
3. For the freshness zone, use a separate regulator FreshZone (if available).

Check the accuracy of the settings using external thermometer (put it in a glass of water on the middle shelf). If the difference with the set temperature exceeds ±1°C, calibration or diagnostics of the sensor is required.

⚠️ Attention: In models Dimetra with function SuperCool (fast cooling) the temperature in the refrigerator compartment temporarily drops to +2°C. Do not leave the function on for more than 6 hours - this will increase the load on the compressor.

3. Defrosting the Dimroth refrigerator: step-by-step instructions

Despite the system NoFrost or FrostFreerefrigerators Dimetra require periodic defrosting. Frequency depends on the model:

• 🔄 NoFrost — once every 1-2 years (for cleaning and disinfection).
• ❄️ FrostFree — once every 6-12 months (if ice forms >5 mm).
• ⏳ Old models (before 2018) — once every 3-4 month.

How to defrost a refrigerator Dimetra correctly:

1. Unplug the refrigerator. Do not pull the plug from sockets —use the power button (if available) or the machine in the panel.
2. Take out all the food. Use cooler bags or a bowl of ice to keep it cold.
3. Place a tray to collect water (in models with FrostFree ice melts faster than in NoFrost).
4. Open the doors wide open and wait for complete thawing (from 2 to 8 hours depending on the ice layer).
5. Do not use a hair dryer or sharp objects to speed up the process - this will damage the seal and plastic.
6. Wipe the internal surfaces with a soda solution (1 tbsp per 1 liter of water) or a special product for refrigerators.
7. Dry the chambers with a towel and turn on the refrigerator. Let it work for 1-2 hours without food so that the temperature stabilizes.

Features for models with NoFrost:

• 💨 The fan may continue to work even after being turned off - this is normal (it stops after 1-2 minutes).
• 🚫 Do not wash the ventilation grilles under running water - only with a damp cloth.

What will happen if you do not defrost the refrigerator?

When there is a thick layer of ice (more than 1 cm), the compressor begins to wear out, which increases energy consumption by 20-30%. In models with FrostFree ice may block the drainage hole, which will lead to water accumulation under the vegetable drawers.

After defrosting, check:

• 🔊 Noise level - if it becomes louder, the fan blades may be touching the ice.
• 💧 No puddles under the refrigerator (if there are, clean the drainage hole with a cotton swab).

4. Common mistakes during operation and how to avoid them

Even experienced users make mistakes that shorten the life of the refrigerator Dimetra. Here are the most critical ones:

• 🔥 Hot foods. Some believe that the freshness zone FreshZone is intended for cooling hot dishes. In fact, temperature changes lead to condensation and increased load on the compressor. Cool food to room temperature before placing it in the refrigerator - this rule applies even to models with the function SuperCool.
• 🧊 Overloading the freezer compartment. If food is packed tightly, air circulation is disrupted and the temperature is distributed unevenly. In freezers Dimetra with a system NoFrost this can lead to icing of the fan.
• 🚪 Prolonged opening of the door. In models with electronic control (for example Dimetra SmartCool), when the door is open for more than 2 minutes, a sound signal sounds. Ignoring this signal increases energy consumption by 15-20%.
• 🧼 Aggressive detergents. Chlorine-containing substances destroy the seal and coating of the shelves. Use only specialized products (for example Top House or Electrolux Fridge Cleaner).

Another typical problem is incorrect position of the refrigerator. If it is not level (checked by level), the door may not close tightly, which leads to:

• 📈 Increased energy consumption (up to 25%).
• ❄️ Formation of ice on the back wall (even in models NoFrost).
• 🔊 Increased vibration and noise.

To level the refrigerator Dimetra:

1. Use the adjustable legs (turn counterclockwise to lift).
2. Check the gaps: in the front there should be 2-3 cm for air circulation, in the back - 5-10 cm.
3. If the floor is uneven, use anti-vibration stands (for example, VibraStop).

⚠️ Attention: In refrigerators Dimetra with a display on the door (models Dimetra DisplayLine) if the closure is not tight, an error may occur E1 or Door Alarm. If the signal does not disappear after checking the seal, a reboot is required (turn off the refrigerator for 5 minutes).

5. Care and cleaning: how to extend the life of the refrigerator

Refrigerators Dimetra require regular maintenance, but many procedures can be performed independently without calling a technician. Here is a monthly checklist. maintenance:

For deep cleaning:

1. Turn off the refrigerator and take everything out shelves/drawers. They can be washed in warm water with a mild detergent (for example, Fairy for dishes).
2. To remove odors, use a solution of soda (2 tablespoons per 1 liter of water) or activated carbon (put 5-6 tablets in a small container on the top shelf for 24 hours).
3. In models with NoFrost clean the fan from dust using a vacuum cleaner with a narrow nozzle (without touching the blades).
4. Wipe the condenser (grid on the back wall) with a dry cloth - this will improve heat transfer and reduce the load on the compressor.

What not to do:

• 🚫 Use abrasive sponges or metal scrapers - they scratch the coating.
• 🚫 Wash the inside of the refrigerator with hot water - this can deform the plastic.
• 🚫 Place heavy objects on the top cover (for example, a microwave) - this interferes with ventilation.

For models with antibacterial coating (for example, Dimetra BioFresh) do not use alcohol-containing products - they destroy the protective layer; wiping with a damp cloth and then drying is sufficient. data-i="239">antibacterial coating

6. Storing food: how to preserve freshness as much as possible

Refrigerators Dimetra are equipped with zones with different temperatures and humidity, which allows for optimal distribution of food:

Storage features in zones FreshZone:

• 🥩 Meat and fish in vacuum packaging can be stored for up to 5 days (in the usual zone - no more than 2).
• 🍓 Berries and mushrooms remain fresh for up to 7 days (in the main chamber - 2-3 days).
• 🧀 Blue cheeses (for example, Dor Blue) are not It is recommended to store next to other products - use a separate container.

For the freezer:

• ❄️ Optimal temperature for long-term storage - -18°C.
• 📦 Pack food in portions - repeated freezing worsens the taste and texture.
• 🗓️ Mark packages with the date - most products should not be stored in the freezer for longer than 6 months.

⚠️ Attention: In freezers Dimetra with the function SuperFreeze temperature temporarily drops to -24°C for quick freezing. Do not load more than 3 kg of food at this time - this will lead to overheating of the compressor.

7. Typical malfunctions and methods for their elimination

Refrigerators Dimetra are known for their reliability, but even they can break down. Here are the most common problems and their causes:

Some errors can be eliminated yourself:

• 🔌 If the refrigerator does not turn on, check the fuse in the plug (in models Dimetra older than 2019, it may blow out during a power surge).
• 💧 If water accumulates in the refrigerator compartment, clean the drainage hole (located on the back wall above the tray for vegetables).
• 🔊 If the refrigerator is humming loudly, check that it is not touching walls or furniture - vibration increases the noise.

For complex faults (for example, a freon leak or a breakdown of the electronic unit), professional repairs are required. In service centers Dimetra diagnosis costs from 1,500 rubles, compressor replacement - from 5,000 rubles (prices depend on the model and region).

⚠️ Attention: If your refrigerator Dimetra is under warranty, do not try to repair it yourself - this will void the warranty. The official warranty period for the compressor is 5 years, for other parts - 2 years (for models purchased after 2021).

8. Frequently asked questions (FAQ)

Is it possible to place a Dimroth refrigerator next to a stove or radiator?

No, this violates the operating rules. The refrigerator should be located at least 50 cm from heat sources. Otherwise, the compressor will work in increased mode, which will lead to increased wear and increased energy consumption by 30-40%. If there is no other option, use a heat-reflecting screen (for example, a sheet of foil polystyrene foam).

How often should you defrost a refrigerator with the NoFrost system?

Refrigerators Dimetra s NoFrost do not require regular defrosting to remove ice, but they need to be turned off 1-2 times a year to cleaning and disinfection. During defrosting, also check the condition of the seal and ventilation grilles. If ice appears in the freezer compartment, this is a sign of a malfunction (for example, failure of the defrost heater).

Why is it too cold in the refrigerator compartment, and warm in the freezer?

This problem is typical for models with single-circuit cooling system (found in old refrigerators Dimetra until 2017). Reasons:

• Clogged capillary tube.
• Malfunction of the magnetic valve (in two-compressor models).
• Freon leak.

You won’t be able to fix the problem yourself—diagnosis is required at a service center. Temporary solution: set the freezer regulator to maximum and the refrigerator regulator to minimum.

How to transport a Dimroth refrigerator to a new place?

Transportation rules:

1. Turn off the refrigerator 24 hours before transportation and defrost it.
2. Secure the compressor with shipping bolts (if provided by the design).
3. Transport the refrigerator only in a vertical position. If this is not possible, lay it on its side so that the compressor tubes are on top (maximum tilt angle is 40°).
4. After transportation, let the refrigerator stand for 4-6 hours before turning it on (this time is needed to stabilize the oil in the compressor).

If the refrigerator was transported lying down, before turning it on, check the integrity of the tubes and the absence of freon leaks (sign - hissing or oil stains).

What products cannot be stored in the Dimrot refrigerator?

Some products spoil faster when stored in the refrigerator:

• 🍌 Bananas, pineapples, mangoes - at temperatures lower +10°C they lose their taste and texture.
• 🍅 Tomatoes - become mealy.
• 🧅 Onions and garlic - sprout or mold due to dampness.
• 🥖 Bread (longer than 3 days) - best stored in a bread bin or freezer.
• ☕ Coffee beans - absorbs foreign odors.
• 🍯 Honey - crystallizes at temperatures below +5°C.

It is also not recommended to store open canned food in the refrigerator (due to the risk of metal oxidation) and potatoes (they turn into sweet due to the conversion of starch into sugar). Dimetra open canned food (due to the risk of metal oxidation) and potatoes (turn sweet due to the conversion of starch to sugar).
