Finding the exact identification number is the first action that the owner of a household appliance needs to take equipment Bosch before purchasing spare parts, searching for instructions or registering for warranty repairs. Many users mistakenly believe that the serial number and model are the same thing, but for a German design engineer these are completely different concepts. Serial number is unique for each specific instance released at the factory, while Model (often referred to as E-Nr) determines the design features, color, size and functionality of an entire series of devices.
Understanding this difference is critical. If you order a compressor or door based only on the serial number, there is a high probability of receiving a part that does not physically fit your unit. Bosch produces equipment in factories throughout Europe, and markings may vary slightly depending on the year of manufacture. In this article, we will analyze in detail all the possible locations of the information plate and learn how to read the data correctly.
It is also important to note that the location of the sticker directly depends on the type of refrigerator: built-in or free-standing. The design of the case dictates the logic of placement of technical documentation. The E-Nr (Equipment Number) code is the most important identifier for selecting spare parts and documentation. Let's look at the main locations where manufacturers place this vital information.
⚠️ Attention: Do not try to peel off the information sticker from the case to make it close-up photo. The adhesive on factory labels Bosch is often very aggressive, and you risk damaging the refrigerator's coating or the sticker itself, making it unreadable. It’s better to photograph it right on the spot using a flash.
The main locations of the information plate
Engineers Bosch are guided by European marking standards, but depending on the series and year of production they may change the location nameplate The most common location for freestanding models is side wall inside the refrigerator compartment. Usually the sign is located on the left wall, closer to the doorway or on the middle shelf.
If you find nothing on the side wall, carefully inspect the inside surface of the refrigerator door. Often, especially in models with the system NoFrost, the sticker is hidden behind a plastic trim or at the end of the door so that it does not spoil the view of the products. In some older models, information could be applied directly to the back wall of the unit, outside, next to the compressor.
For built-in models, the situation is complicated by the design of the furniture box. Since the side walls are covered with a kitchen unit, and the door is decorated with a facade, it is more difficult to find the nameplate. In such cases, manufacturers often duplicate information on hinge of the hinge (the top of the door) or on the end of the door, which is visible only when fully swinging.
- 📍 The left inner wall of the refrigerator compartment (the most common location).
- 📍 The inner surface of the door of the refrigerator or freezer.
- 📍 The base part of the refrigerator (rare, but found in older series).
- 📍 The rear metal wall on the outside (typical for built-in models).
Specifics of search on embedded models
Owners of embedded equipment Bosch often have to perform miracles of acrobatics to get to the desired number. Since the side walls are tightly closed with the cabinet walls, and a tabletop or shelf can be installed on top, standard search places are not available. In this case, the main landmark becomes the doorway.
Carefully inspect the upper end of the door. Sometimes the sticker is glued so that part of it is on the static part of the body, and part is on the movable door. In this case, you can see the full code only when the door is open. It is also worth checking the space around loop connection. Engineers often place a smaller copy of the nameplate there or a sticker with only the model number.
If a visual search does not produce results and you are planning a major repair, partial dismantling may be required. However, before unscrewing the facade fasteners, try shining a flashlight into the gap between the top of the refrigerator and the cabinet shelf. Sometimes, although this is a violation of ergonomics, a sticker is glued to the top cover of the unit, and it can only be seen from above.
What to do if the sticker is erased or peeled off?
If the sticker is damaged by time, moisture or mechanical stress, it is visually impossible to restore the exact model number. In this case, if the refrigerator is working, you can try to read the number through the diagnostic mode (if the model supports Smart Home and digital control), but this does not always work. The safest thing to do is contact an authorized service with a photo of the nameplate, even a partial one, or a purchase receipt, where the full article number (E-Nr) can be indicated.
Structure and decoding of the E-Nr number
After you have found the treasured sticker, you will see a set of letters and numbers. For an untrained user, this is a chaotic cipher, but in fact it is a strictly structured code. The main field that interests us is labeled as E-Nr or FD. It is this combination of 10 characters (for example, KGN39XI30R/01) that is the key to spare parts catalogs.
Let's look at the code structure using a typical model as an example. The first three characters usually indicate the device type and series. For example, KGN indicates a two-chamber refrigerator with a NoFrostsystem, and KGV indicates a model with a drip defrosting system. The numbers following them indicate the volume and dimensions. Letters in the middle of the code often indicate the color of the case and the type of control (mechanical or electronic).
The last part of the code, separated by a slash (for example, /01 or /02), indicates Indexation or modification. This is a critical parameter. Two models may look identical and have the same base code, but differ in index. This means that they may have different compressors, fans or electronic boards inside. Ordering a spare part without taking into account the index is a sure way to get a non-working unit.
| Symbols in the code | Value | Example |
|---|---|---|
| 1-3 symbol | Device type (series) | KGN (NoFrost), KGV (LowFrost) |
| 4-6 symbol | Volume and dimensions | 39 (approximately 390 liters) |
| 7-9 symbol | Design and color | XI (stainless steel) |
| After "/" | Indexation (modification) | /01, /02, /03 |
How to determine the year of manufacture by FD number
One of the most common tasks for the owner is determining the age of the equipment. This is necessary to understand whether it makes sense to repair the old unit or whether it is easier to buy a new one, as well as to check the warranty period. The sign Bosch has a field FD (Fabrication Date) followed by a long number. It is this that stores the production date.
Date encoding is not obvious. You don't need to look for the year explicitly (for example, 2021). The system Bosch uses a mathematical code. You need to take the first two digits of the long number after FD. To these two digits you need to add a constant - number 14. The resulting amount will indicate the year of issue.
Let's consider an example. Let's say the nameplate says: FD 980500123. We take the first two digits - 98. Add 14: 98 + 14 = 112. Since we live in the 21st century, we are interested in the last two digits of the result. In this case, 12, which means 2012. If the sum exceeds 100, we simply discard the first unit. For models released after 2020, the logic remains the same, but the result will be, for example, 35 (2021: 07 + 14 = 21, stop, a correction is needed here: for 2021 the code will be 07+14=21, for 2023: 09+14=23).
⚠️ Attention: The formula "add 14" works for most models manufactured after 2000. For very old equipment (before 2000) or specific industrial series, the encoding logic may differ. If the billing year seems illogical to you (for example, the refrigerator looks new, but the calculation shows 1995), double-check the calculations or check with the official service center.
Differences in markings for different series of equipment
Holding BSH, which owns the brand, produces equipment under different brands, including Siemens, Neff i Gaggenau. Often their production lines and even the design of their components are common, but the markings may have their own nuances. For example, the Siemens model code may begin with different letters, but the principle of searching for the plate remains identical. Bosch.
The series VitaFresh and Home Connectdeserve special attention. In smart refrigerators that support control from a smartphone, the digital twin of the device in the application also contains complete information about the model. If the physical sticker is damaged, go to the application Home Connect, select your device, and in the "About Device" section you will find the complete one E-Nr.
It is also worth mentioning the difference in the labeling of the American and European versions. Equipment intended for the US market may have a label in English marked “Model Number”, while European versions use the abbreviation E-Nr. The structure of the code is preserved, but the visual design of the plate is different.
☑️ Check before ordering spare parts
Typical mistakes when searching and ordering spare parts
The most common mistake is confusion between the serial number (S-Nr) and model number (E-Nr). The serial number is unique, like a fingerprint, and is mainly needed by the factory warranty department. It is useless for searching for a plastic shelf or rubber seal. If you enter the serial number into the search for spare parts, the system most likely will not find anything or will generate an error.
The second mistake is ignoring indexing. As mentioned earlier, models may differ in the last digit after the line. When ordering a heating element or control board for a model KGN39.../01, when you have .../02, you risk receiving a part with a different pinout or fastener geometry. Always check this parameter.
The third problem is searching by the name of the series, printed in large font on the refrigerator itself (for example, Klassic or Maxx). These are marketing names that combine hundreds of different models. They do not provide technical information for selecting components. Look only for a small metal or paper sticker with a barcode.
Is it possible to restore a sticker if it has been erased?
It is impossible to restore a factory sticker at home, since this is a secure printing product. However, if you know the exact model (if you remember at least part of the code or bought it in the same store with a friend), you can try to find it in catalogs by its external features. But for an accurate repair, it is better to call a specialist who can identify the series based on the internal structure of the unit.
Where is the sign if the refrigerator is built into a cabinet?
In built-in models, access to the side walls is closed. Look for the sticker on the top edge of the door (immediately under the trim strip), on the inside of the door, or on the plinth panel below. Sometimes it is necessary to remove the decorative strip of the facade in order to see the nameplate on the metal door.
What does it mean if there is a letter “Z” in the model code?
The letters in the model code indicate various characteristics: color, type of handle, country of assembly or the specific retail chain for which the batch was produced. Only the manufacturer knows the exact decoding of each letter, but this is not required for selecting spare parts - the entire code is important.
Why is the model number on the box and on the refrigerator different?
This is impossible, the numbers must match. If they are different, you may be looking at the packaging lot number or logistics barcode code rather than the E-Nr. Make sure that you are comparing the string “E-Nr” or “Model”.
How to find out the model if the refrigerator does not turn on and there is no sticker?
If the sticker is destroyed and the equipment does not work, it is extremely difficult to identify the model. You can try to find the original instructions or warranty card, where the full article number is often written down. In extreme cases, identification will be carried out by a service center technician using internal components (compressor, evaporator).
