The correct first start of German Bosch equipment guarantees many years of flawless operation compressor and NoFrost system. Many users make the mistake of starting operation immediately after unpacking, which can lead to breakdown due to oil not returning to the compressor crankcase.
The process of activating the device requires compliance with the time intervals and the exact sequence of actions described in the manufacturer’s technical regulations. Ignoring the refrigerant stabilization stage often causes increased noise or incorrect cooling in the first days.
Preparation for the first start-up and transportation
Before wondering how to turn on the Bosch refrigerator, you need to make sure that the unit is installed correctly. The equipment should be placed flat, hard surfaceaway from direct sunlight and heating devices. It is critical to maintain clearances for ventilation: the distance to the back wall should be at least 5 cm, and at least 2-3 cm on the sides.
If the device was transported horizontally or was strongly tilted, it needs time for the oil to spread. Compressor should not be started “dry” as this is fraught with water hammer and failure of the piston group.
⚠️ Attention: If the refrigerator was transported lying down, the settling time should be at least 12-24 hours. For vertical transportation, 2-4 hours of rest is sufficient.
External inspection of the housing and seals is also a mandatory procedure. Make sure that there are no dents on the doors and that they fit tightly around the entire perimeter. Any defects can disrupt the tightness of the chamber, forcing the compressor to work in increased mode. magnetic seals fit tightly around the entire perimeter. Any defects can disrupt the seal of the chamber, forcing the compressor to work in increased mode.
Removing transport elements
The original packaging contains elements that absolutely cannot be left during operation. Inside the refrigerator and freezer compartments, as well as on the outer walls, there may be fixing tapes, foam blocks and tape. Removing them is the first step before pressing the power button.
Particular attention should be paid to the internal shelves and drawers. They are often secured transpiration clamps or with tape to prevent movement during delivery. It is necessary to remove all removable elements, remove their packaging and install them back according to the diagram in the instructions.
☑️ Check before turning on
Don't forget to check the presence and condition of vegetable containers and egg trays. Plastic becomes brittle at low temperatures, so any cracks that occur during careless removal of packaging can lead to breakage of parts during operation.
Power connection and requirements
Modern Bosch models are equipped with energy-efficient compressors that are sensitive to voltage changes. The connection must be made only separate socket with grounding. The use of extension cords, tees or adapters is not recommended, as they can cause overheating of the contacts and a fire.
It is important to check that the electrical parameters comply with the requirements specified on the technical sticker, usually located inside the refrigerator compartment or on the back wall. The rated voltage is most often 220-240 V at a frequency 50 Hz.
If your region experiences frequent power surges, it is advisable to use a stabilizer. This will protect electronic control module from combustion, the repair of which is an expensive procedure.
Initial activation and temperature setting
After connecting to the network, the device may not make any sounds immediately. On electronically controlled models, the display first lights up and the system self-diagnostic process begins. Mechanical models begin to work immediately after current is supplied to the thermostat.
To turn on the electronic control, you must press the corresponding button on the panel, often indicated by a power symbol or On/Off. After activation, it is recommended to set average temperature values for initial heating.
| Storage area | Recommended temperature | Operating mode | Purpose |
|---|---|---|---|
| Refrigerator compartment | +4°C ... +5°C | Normal | Basic foods, drinks |
| Fresh zone (VitaFresh) | 0°C ... +2°C | Intense | Meat, fish, dairy products |
| Freezer compartment | -18°C ... -20°C | Deep Freeze | Long-term frozen storage |
| SuperCooling mode | Temporary reduction | Automatic | Fast cooling of new loading |
You should not load the camera with products right away. An empty refrigerator will reach the set temperature faster, which will allow the system to automatically return to normal operation. Typically this process takes from 4 to 8 hours depending on the volume of the chambers and the ambient temperature in the room.
Indication and sound signals
Bosch two-chamber refrigerators are equipped with an advanced user notification system. When you turn it on for the first time, the alarm indicator may light up or a sound signal may sound, indicating that the temperature in the chambers has not yet reached the set values. This normal situation is for a new device.
Various symbols may appear on the display. For example, a flashing temperature indicator indicates cooling is in progress. If the indicator is on Alarm or an intermittent sound is heard, this means that the door has been open for too long or the temperature inside has risen above normal.
⚠️ Attention: If the sound signal does not stop after the chambers have cooled, check the tightness of the door. A foreign object in the seal may break the seal.
It is important to distinguish between fault signals and operating mode signals. Some models make a short sound when pressing buttons, which confirms the command has been accepted. A long beep more often indicates the need for user intervention.
What do the error codes on the display mean?
Error codes (for example, E01, F2) indicate specific malfunctions of the sensors or defrost system. The decoding of the code for your model Bosch can be found in the table at the end of the instructions or on the manufacturer’s official website. Do not ignore their appearance.
Quick freezing and super cooling modes
Special functions are provided to speed up the process of entering the mode or when loading a large amount of warm products. The mode SuperCooling (super cooling) temporarily reduces the temperature in the refrigerator compartment, providing rapid cooling of new products without increasing the temperature of the stocks already lying there.
In the freezer, a similar function is performed by the mode SuperFrost. It switches the compressor to continuous operation until the minimum temperature is reached or until it is manually switched off. This is useful when preparing seasonal berries or meat.
Activation is done through the control panel. Models without a display may have a separate button, while models with a screen may have a touch selection. It is not recommended to keep these modes turned on constantly, as this increases the wear and tear of the compressor. Energy consumption The SuperCooling and SuperFrost functions are intended for short-term use. After automatic shutdown or manual deactivation, the device will return to standard settings. energy consumption and compressor wear.
Frequent problems during the first start
Even if all instructions are followed, users may encounter phenomena that are mistaken for a breakdown. For example, the noise of gurgling liquid in the tubes is the normal sound of circulation refrigerant through the system. It can be heard even after the temperature has risen.
Heating of the side walls of the case is another common issue. In modern Bosch models, condensation grilles are often built into the side walls for better heat transfer. Therefore, moderate heating of the sides during active operation of the compressor is the normand not a defect.
If the refrigerator does not turn on after connecting to the network, check the presence of voltage in the socket and the tightness of the plug insertion. It is also worth making sure that the door is tightly closed, as some models block startup if the door open sensor is active.
⚠️ Attention: If the refrigerator makes a loud knock, vibration or a burning smell, immediately unplug it and contact an authorized service center. Self-repair may lead to loss of warranty.
In conclusion, it is worth noting that proper operation begins with a proper start-up. Compliance with time intervals and sequence of actions will allow Bosch appliances to work quietly and efficiently for many years.
Why does the refrigerator operate louder than usual in the first hours?
At the beginning of operation, the compressor operates at maximum power to cool the entire volume of the chambers and internal walls. This creates an increased noise level, which will decrease when the target temperature is reached.
How long should a Bosch refrigerator sit before turning on?
If the unit was transported in an upright position, 2-3 hours is enough. If in horizontal mode, you need to wait at least 12 hours, or better yet a full day, for the oil to flow into the compressor.
Why does the Alarm indicator light up after the first turn on?
This is a signal that the temperature in the chamber is even higher than normal. After the refrigerator has operated for several hours and cooled the internal volume, the indicator will go out automatically.
Is it possible to load food immediately after turning it on?
Technically it is possible, but not recommended. It is better to wait until the refrigerator reaches operating mode (usually 4-6 hours) so as not to create excess load on the compressor and not to disturb the temperature regime of already stored products.
What to do if the refrigerator does not freeze after 10 hours of operation?
Check that the door is tightly closed, that there are no obstacles to the air circulation inside and that the temperature settings are set correctly. If the problem persists, you need to call a technician.
