Finding the exact identifier of household appliances is the first action that must be performed when a malfunction occurs or the need to order original spare parts. The owner of German Bosch equipment is often faced with the fact that there are no numbers on the front panel of the device indicating a specific modification. This is done for the sake of aesthetics, but creates certain difficulties when contacting a service center or searching for instructions on the Internet.
An incorrectly defined series can lead to the purchase of an unsuitable filter, seal or electronic module, since externally identical units can have completely different internal contents. Serial number (E-Nr) is a unique key that gives access to technical documentation and catalogs spare parts specifically for your device. In this article we will analyze in detail all possible locations of the marking.
Understanding the structure of the marking will allow you not only to find the necessary information, but also to independently decipher the year of manufacture, country of assembly and basic characteristics of the unit. This knowledge will save time when communicating with specialists and will help avoid mistakes when servicing yourself.
Main locations of the factory tag
Bosch engineers have standardized the placement of information stickers, however, depending on the year of manufacture and series of the refrigerator, their position may vary. Most often, a label with technical data, including E-Nr (product number) and FD (production date), is located inside the refrigerator compartment. Carefully inspect the side walls, paying special attention to the upper corners.
If no markings are found on the side walls inside the chamber, the next logical step is to inspect the back wall. The tag can be glued directly to the plastic panel or to the metal surface of the evaporator if there is no plastic there. In some NoFrost models, the sticker is hidden behind the bottle shelf or in a niche above the upper compartment.
There is also a possibility that the information sticker is placed on the base of the unit, hidden behind the decorative grille at the bottom of the front panel. To get to it, sometimes you need to remove the plastic cover, which is not always convenient. That is why the inner walls of the refrigerator compartment remain a priority place to search.
⚠️ Attention: Never try to peel off the entire factory tag if it is located in an inconvenient place. Carefully rewrite the data or take a photo of them, as damage to the sticker may complicate warranty service.
Deciphering the barcode and E-Nr number
Finding the sticker is only half the task. It contains many numbers and letters that need to be interpreted correctly. The most important parameter is the code E-Nr (or simply Nr), which usually consists of a combination of letters and numbers separated by a slash, for example, KGN39XI30R/01. It is this code that must be entered into the search bar on the manufacturer’s website or in spare parts catalogs.
A little lower or next to the main number is often indicated FD number, which is a four-digit number. The first two digits of this code indicate the year of production, and the second two indicate the month. For example, code 9805 means that the refrigerator came off the assembly line in May 2019 (9+20=2019, since the countdown starts from 1990). For models released after 2020, the first digit will be 1, 2, and so on.
There is also a barcode on the sticker, which is read by scanners in the warehouse. The product number may be duplicated below it. It is important not to confuse serial number (S-Nr), which is used for logistics, with the model range. To search for instructions and diagrams, you need exactly the type of device indicated in the E-Nr field.
Search for the model in the documentation and on box
In a situation where the sticker inside the refrigerator is damaged, peeled off or worn off, do not despair. An alternative and often more reliable source of information is the technical data sheet of the device, which is issued to the buyer upon purchase. The cover or first page of the document always indicates the complete model range and specific modification.
Also save the cardboard packaging if you are planning transportation or warranty exchange in the near future. On the side edges of the box there is a large marking containing all the necessary codes, including E-Nr and barcodes. This is especially true for new refrigerators that were purchased recently and the packaging has not yet been disposed of.
If you still have a receipt or warranty card filled out by the seller, the model may also be stated there, although sellers often shorten the name to the basic series. To accurately select spare parts, the data from the receipt may not be enough, so priority should still be given to the passport or physical sticker on the case.
Use of digital services and the Home Connect application
Modern Bosch refrigerators are often equipped with smart home modules and support technology Home Connect. If your unit is connected to a Wi-Fi network and paired with a smartphone, you can find out its exact model directly in the application. Go to the device settings in the application, where the full E-Nr will be indicated in the “Device Information” or “About the System” section.
This method is convenient because it eliminates the need to physically look inside the refrigerator or look for papers. The device’s digital profile is synchronized with the manufacturer’s server, providing up-to-date configuration data. However, this method only works for models with support for intelligent control, released in recent years.
For older models that do not have a remote control function, the only digital trace may be registration on the manufacturer’s website, if you did it at the time of purchase. In the user's personal account, the history of registered equipment with full specifications is often saved.
What to do if the application does not see the refrigerator?
Make sure that the Home Connect module is activated. To do this, press and hold the module's power button on the control panel for 3 seconds until the Wi-Fi icon appears. If this does not help, check the router settings: the network should be 2.4 GHz, since refrigerator modules often do not support 5 GHz.
Correspondence table of prefixes and series of refrigerators
Understanding the structure of the model number helps to quickly determine the type of refrigerator. The first letters in the E-Nr code indicate the dimensions and type of installation. Below is a table that helps you navigate the main series of Bosch household appliances.
| Model prefix | Device type | Characteristic features |
|---|---|---|
| KGN | Two-chamber refrigerator | Freestanding, system NoFrost |
| KGV | Two-chamber refrigerator | Freestanding, drip system (LowFrost) |
| KIR | Built-in refrigerator | For installation in a kitchen unit |
| GIN | Freezer camera | Free-standing or built-in, NoFrost |
| VTI | Wine cabinet | Specialized wine storage |
Knowing the prefix, you immediately understand which device you are dealing with. For example, if you are looking for a spare part for a shelf, knowing that you have a series KGV with the LowFrost system will tell you that the back wall may be covered with an ice crust, which is normal for this design, unlike the series KGN.
What to do if the tag is completely lost
In rare cases, When a sticker has been removed by previous owners, damaged by harsh cleaning agents, or is simply missing, the search for a model turns into a detective investigation. In such a situation, you can try to determine the model by external signs and characteristics, checking them with catalogues.
Pay attention to the control panel, the location of the handles, the shape of the doors and the internal configuration of the shelves. These visual markers are often unique to a particular series. Take photos of the refrigerator outside and inside to show them to a specialist at a spare parts store or service center.
☑️ Action plan for a lost tag
You can also try to find the original instruction manual if it is preserved in paper form. A list of compatible models is often printed on the last page or cover, although this does not guarantee 100% accuracy if the instructions were universal for the entire line.
⚠️ Attention: Technical characteristics and design of refrigerators may vary slightly within the same model range depending on the year of manufacture. Before ordering expensive components (compressor, control board), always check the appearance of the part with yours, even if the numbers seem similar.
Common mistakes when identifying the model
One of the common mistakes is trying to find the model by the number on the rear metal grille of the condenser. There are often stamped technical data of the compressor itself or the metal stamping date, which are not directly related to the model of the entire refrigerator. Compressor can be replaced during repairs, and its marking will differ from the factory one.
Another error is confusion between the color code and the model code. Some stickers have codes indicating the color of the case (for example, Inox, White, Black). If you enter this code into the search, you will receive a list of all refrigerators of this color ever produced, which will not help in selecting spare parts.
You should not rely only on visual similarity with photographs in online stores. The door design can be the same for dozens of models, differing in volume, type of refrigerant and electronics. Always look for an alphanumeric code starting with the letters KGN, KGV or KIR.
FAQ: Frequently asked questions
Is it possible to recognize the model of a Bosch refrigerator by the sound of its operation?
No, this is impossible. The sound of the compressor and fans depends on the technical condition, amount of refrigerant and chamber load, and not on the model number. Visual data is needed for identification.
Where is the model number in two-chamber refrigerators with a bottom freezer?
In such models (KGN, KGV series), the sticker is almost always located on the left or right wall of the upper refrigerator compartment, often at eye level or slightly above the middle shelves. It is usually not in the freezer.
What does the FD code on the sticker mean?
The FD code (Fabrication Date) indicates the production date. This is a four-digit number, where the first two digits are the year (taking into account the addition of 20 to the value for years after 2000, for example, 23 is 2020+3=2023, or 98 is 1990+8=1998), and the second two are the month of issue.
Is there a difference between E-Nr and S-Nr?
Yes, there is. E-Nr (Geratenummer) is the device number that determines its model and configuration. S-Nr (Seriennummer) is a unique serial number of a specific item, used for warranty and production tracking. To search for spare parts you need E-Nr.
Is it possible to find a model via a QR code?
Modern Bosch models actually have a QR code on the energy sticker. Scanning it with your smartphone may redirect you to a product information page that will list your model. However, old refrigerators do not have such a function.
