Finding the exact designation of household appliances often turns into a real quest, especially when an urgent order of spare parts or searching for instructions is required. Owners of German equipment Bosch face this when the unit stops freezing or requires filter replacement. The main difficulty is that the markings can be hidden in non-obvious places, and its absence makes it impossible to select compatible components.
Many users mistakenly look for only the serial number, believing that it is enough for identification. However, for a service center or spare parts store, it is the model number (E-Nr) that is critically important, which contains encoded information about the year of manufacture, color, type of refrigerant and country of assembly. Without this data, there is a high risk of purchasing the wrong part.
In this article we will analyze in detail all possible locations of information plates, learn to decipher complex alphanumeric codes and understand why one and the same visually refrigerator can have different technical data sheets. The only guaranteed identifier of your specific one piece of equipment is the full E-Nr code located on the nameplate.
Factory information plate: main source of data
The first and most obvious place where the manufacturer places all the technical information is the factory sticker or metal plate. In refrigerators Bosch it is most often made in the form of a silver or white sticker with black text. The location of this element is not accidental: engineers choose places that are protected from direct mechanical impact, but accessible during a standard inspection.
Most often, the plate can be found on the inner wall of the refrigeration chamber. Pay attention to the left side wall, closer to the shelves, or the space above the top vegetable drawer. In some models, especially built-in series, the sticker may be shifted to the end of the door, which is visible only when the shutter is opened wide.
If there is no sign inside the chamber, carefully inspect the rear wall of the housing from the outside. However, this option is less likely for modern models, since if installed tightly against the wall, it will be impossible to read the data without moving the heavy unit away. On the plate you are interested in the line E-Nr or Modell.
Searching for markings in the freezer compartment
In two-chamber refrigerators and models NoFrost manufacturers often duplicate information or place it exclusively in the freezer compartment. This is due to the layout of the internal space and the thickness of the thermal insulation. If you do not find the data in the main compartment, go to the freezer.
Open the freezer door and inspect the side walls. In models with the system NoFrost the plate is often hidden behind the plastic evaporator panel or placed on the inside of the door, next to the seal. Sometimes it is located on the end of the door itself, hidden from view when the door is closed.
It is important to note that in chest freezers or combined models with a bottom freezer, the sticker can be glued to the internal partition between the chambers. Look for a silver rectangle with a logo Bosch and many small symbols.
☑️ Search for the nameplate
Built-in appliances: specifics of label placement
For owners of built-in refrigerators Bosch finding the model number is the most difficult. The design of such units requires installation in a furniture niche, which often blocks access to standard marking locations. Manufacturers take this into account and provide alternative options.
Be sure to check the end of the door from the hinge side. Often it is there, on a narrow strip of metal or plastic, that laser engraving is applied or a smaller version of the sticker is glued. It is also worth looking into the space between the refrigerator body and the furniture façade if the design allows access to be slightly opened.
⚠️ Attention: When looking for markings on built-in appliances, do not try to dismantle the furniture façade yourself if you are not sure of the fasteners. This can lead to damage to the hinges or decorative panel.
In some cases, the instructions or warranty card pasted into the product passport contain the same information as the sticker on the case. If the equipment was installed recently, check the documents - the code there E-Nr is often rewritten by the installers or indicated in the delivery note.
What to do if the sticker has worn off?
If the nameplate is unreadable, try carefully highlighting its location with a flashlight at an acute angle. Residual adhesive relief or micro-scratches may reveal the outlines of the characters. Also, the code can be duplicated on the box of equipment, if it has been preserved.
Deciphering the model number and serial code
Having found the sticker, you will see a set of letters and numbers, which may seem chaotic. However, code Bosch is strictly structured information. Understanding its structure will help you not only find the right spare part, but also find out the year of manufacture and origin of the unit.
The main identifier is E-Nr (for example, KGN39XI30R/01). The first letters indicate the type of device (K for refrigerator), the next numbers indicate the volume and series, and the letters at the end often code the color and version. After the slash comes the version number (FD), which determines the year of manufacture.
The following is a table that helps you understand the structure of the designations using the example of a typical refrigerator:
| Code element | Example | Value |
|---|---|---|
| Device type | KGN | Combination refrigerator |
| Width/Series | 39 | Width 60 cm, series 3 |
| Design/Color | IX | Stainless steel |
| Version (FD) | 01 | Production modification |
The serial number is worth mentioning separately FD. It consists of 4 or 5 digits. The first two digits (or one if there are only three) indicate the year of manufacture added to a certain base value (often 20 or 10), and the next two indicate the month. For example, the code FD 9805 will mean May 2026 (98 - 80 = 18? No, usually 20 is added to the year for modern ones or 10 for old ones, you need to look at the correspondence table, but the principle remains: this is the date).
Where to look for information if there is no sticker
The situation when the factory the sticker is lost, torn off or faded to the point of being unreadable, which is not uncommon. This is especially common when purchasing equipment secondhand or after long-term use, when aggressive cleaning agents have destroyed it. What to do in this case?
The first option is to look for documents. The warranty card, sales receipt or sales contract always indicates the full model. Even if only the article number is indicated there (for example, KGN39XI30R), this is often enough for an initial consultation with the service.
The second option is to inspect the packaging box. The side edges of the cardboard are always marked with markings identical to those on the refrigerator. If you keep the box “just in case,” it will be a lifesaver. The third option is a personal account on the manufacturer’s website or in an online store, if the purchase was made online and the account is saved.
Why is it important to know the exact modification (FD-number)
Many users are puzzled why the service center requires not just the model name, but the full code with the version. The fact is that Bosch, like many large concerns, is constantly modernizing production. Within one model KGN39... dozens of components may change over several years.
The following may change:
- 🔌 Type of compressor and start relay;
- ❄️ Design of the evaporator and system defrost;
- 🚪 Hinges, handles and seal profile;
- 💡 Type of lamp base and socket.
If you order a seal for version /01, and you have version /15, the door may not close hermetically due to a millimeter mismatch in the profile. The same applies to electronics: control boards may look the same, but have different firmware.
⚠️ Attention: When ordering spare parts based on photos, always check with the seller for compatibility with your FD number. Visual similarity of parts does not guarantee their functional compatibility.
Frequently asked questions (FAQ)
Is it possible to recognize the model of a Bosch refrigerator only by the serial number number?
No, the serial number (usually 10 digits) is used to register the warranty and track repair history, but it does not contain complete configuration information. To order spare parts, you need the code E-Nr.
What does the FD code on the sticker mean?
This is the production version number (Fabrication Date / Version). It indicates the specific month and year of production of this batch, which is critical for selecting parts, since the design may have changed.
Where is the model located on the built-in refrigerator, if it is already installed?
Try to find the sticker on the end of the door on the hinge side. If it is empty, you may need to carefully remove the decorative panel of the facade (if the design allows) or find the data in the documents at the time of purchase.
How to determine the year of manufacture using the FD code?
Usually you need to subtract a certain number from the first two digits of the FD code. For equipment released after 2020, a formula is often used: the first two digits minus 20 give the year. For example, FD 24... is 2026. However, it is better to check the official decoding tables.
