After purchasing or transporting new household appliances, owners are often faced with the question of how to properly start the device for the first time. Refrigeration equipment of the brand Bosch is famous for its reliability, but requires compliance with certain operating rules for the correct operation of the compressor. Incorrect actions at startup can lead to a reduction in the service life of the unit or its breakdown.
In this article we will look in detail at how the Bosch refrigerator turns on, what time intervals must be maintained after transportation and how to set the temperature conditions. Ignoring the manufacturer's instructions in the first hours of operation can cause failure of an expensive compressor, so approach the process responsibly.
Modern models are equipped with electronic control and complex protection systems that are activated only if the switching algorithm is followed. Understanding these processes will help you avoid false alarms when the device does not respond to button presses immediately after connecting to the network.
Settling time after transportation
The most critical stage before turning on for the first time is the time that the device must stand in a vertical position without being connected to the power supply. During transportation, oil from the compressor may have shifted into the refrigerant circulation system, and it takes time for it to flow back into the engine crankcase.
If you ignore this step and start the unit right away, the compressor may run dry or try to compress liquid instead of gas. This creates excess pressure and can lead to mechanical damage to the valves or even jamming of the piston group.
⚠️ Attention: If the refrigerator was transported in a horizontal position, the minimum settling time should be at least 8-10 hours, even if the instructions allow shorter periods for vertical transportation.
The holding time also depends on the ambient temperature environment. In winter, when equipment is delivered in a cold body, it is necessary to allow it to warm up to room temperature. Condensation formed on electronic boards due to a sharp temperature change can cause a short circuit when voltage is applied.
Preparation for the first startup
Before the plug is inserted into the socket, it is necessary to carry out a number of preparatory manipulations. First, remove all shipping locks, tape, and protective films. Pay special attention to the inner packaging - foam blocks and cardboard inserts must be completely removed from the chambers.
The next step will be a thorough hygienic treatment of the internal surfaces. Despite the factory cleanliness, it is recommended to wipe the shelves and walls with a weak solution of soda or a special product for household appliances. This will remove the smell of new plastic and production dust.
☑️ Check before turning on
It is important to ensure that the case is installed correctly. The refrigerator must stand strictly horizontally, which can be adjusted using the front support legs. To check, use a building level or pour a little water on the top panel - the liquid should not flow to one side.
Do not forget to leave enough clearance between the back wall of the device and the wall of the room. Air circulation is necessary for effective heat removal from the condenser, which is especially important in the first hours of operation, when the system enters operating mode.
Activation and configuration process
After the device has settled and prepared, you can begin the electrical connection. Insert the plug into a separate grounded outlet. The use of extension cords or tees is not recommended, as the compressor starting currents can be high.
In models with electronic control EasyControl or HomeConnect activation may not occur instantly. After power is applied, the display may light up, but the compressor will start after a delay of a few minutes. This is the normal operation of the protection system, preventing frequent restarts.
For models with mechanical control, it is enough to turn the temperature regulator to the position recommended by the instructions (usually this is the average value). Electronic panels require pressing the power button, which is often indicated by a power symbol or inscription On/Off.
Why does the refrigerator hum immediately after turning on?
In the first minutes of operation, you may hear a louder hum or gurgle. This is normal: the refrigerant begins to circulate through the system, filling the empty pipes. The sound may be similar to water pouring or hissing. After 10-15 minutes, when the pressure stabilizes, the noise should become quieter and more uniform.
Adjusting the temperature mode should be done after the chambers are empty and the base temperature has been established in them. It is not recommended to load a large amount of food into warm chambers, as this will cause the compressor to wear out for a long time.
Indication and signals of the control panel
Modern refrigerators Bosch are equipped with informative panels that report the operating status. Immediately after switching on, the high temperature or cold indicator may light up. This is a signal that an active cooling process is underway.
It is important to distinguish between normal indicators and alarm signals. If the red symbol with an exclamation point is on or the temperature indicator is flashing, this may mean that the chamber is still warm. Usually this signal disappears on its own after reaching the specified parameters.
| Indicator | Value | User action |
|---|---|---|
| Snowflake | Super freezing mode | Turn off after 24 hours |
| Drop | Automatic defrost | No action required |
| Bell | Door open or not closed | Check tightness |
| Key | Child lock | Hold the button for 3-5 seconds |
Some models support a function SuperCoolthat activates automatically the first time you turn it on to quickly set the temperature. In this mode, the compressor operates continuously until the target values are reached, after which it switches to economical mode.
Typical startup errors
One of the most common errors is an attempt to turn on the device to the network ahead of time. Owners often forget about the need to settle, especially if the refrigerator was in a warm store warehouse. Remember that the oil must return to the compressor.
Another mistake is setting the temperature too low immediately after starting. Trying to set the mode to "Maximum" or -24°C in an empty chamber creates an unjustified load. It is better to start with average values and lower them gradually.
⚠️ Attention: Do not try to speed up the cooling process by opening doors or placing containers of cold water inside. This will disrupt the algorithm of the sensors and may lead to the formation of excess condensate.
Ignoring the installation level also leads to problems. If the refrigerator is tilted, the door may not close tightly, which will lead to constant operation of the compressor and freezing of the evaporator. Adjusting the legs is a mandatory step.
Checking operation after switching on
After starting the device, you need to check its operation during the first day. The main sign of serviceability is the cyclic operation of the compressor. It should turn on, cool the chamber and turn off, going into standby mode.
Check the tightness of the door seals. To do this, you can clamp a sheet of paper between the door and the body: if it is pulled out with force along the entire perimeter, then the seal is in order. Weak spots require adjustment of the hinges.
Pay attention to the heating of the side walls. In modern models, the condenser is often built into the side panels, so heating them up to 40-50 degrees is an absolutely normal phenomenon and not a sign of a malfunction.
Frequently asked questions (FAQ)
How long does it take a Bosch refrigerator to reach temperature after turning on?
Usually it takes 4 to 8 hours to achieve stable operating temperature in empty chambers. Complete freezing and stabilization of all processes take about 24 hours. Only after this is it recommended to load products.
Why does the alarm indicator light up after turning on?
The alarm indicator (often red) lights up because it is still warm inside. This is a normal situation for the first launch. The signal should go off on its own when the temperature drops to the set level.
Is it possible to turn on a Bosch refrigerator through an extension cord?
The manufacturer does not recommend using extension cords, as they may not withstand the starting current of the compressor or have poor contact, which will lead to heating and fire. It is better to use a separate outlet.
Do you need to defrost a Bosch refrigerator before turning it on for the first time?
New models with the NoFrost system do not require defrosting before turning it on. However, if the device has been in storage for a long time, it is worth wiping the inside with a damp cloth to remove dust.
