Finding the exact designation of a Bosch refrigerator model may seem like a trivial task, but in practice owners often face with difficulties when trying to find the treasured sticker. Identification number (E-Nr) is critical for the correct selection of spare parts, ordering specific filters or calling a technician who will bring with him exactly the part that your unit needs. Without an exact code E-Nr there is a high probability of making a mistake, since visually identical refrigerators may have different internal fillings and electronics.
Unlike consumer electronics, where the serial number is often duplicated on the box and in the warranty card, large kitchen appliances may have these places lost immediately after unpacking. Factory marking applied to the device body itself and is the only reliable source of information after installation of the equipment. In this article, we will analyze in detail all possible locations for placing labels on equipment of a German brand, explain how to read complex codes and what to do if standard search places do not produce results.
It is worth considering that the location of the information label may vary depending on the year of manufacture and series of the refrigerator. Modern models often have hidden or non-standard places for marking, which is caused by aesthetic requirements and the desire to make the body as smooth as possible. If you do not find the sticker the first time, do not rush to get upset - most likely, it is simply disguised under structural elements or located in a less obvious area.
Main locations of the nameplate
The most common place where manufacturers, including the BSH concern (Bosch und Siemens Hausgeräte), post technical information - this inner wall of the refrigerator compartment. In most cases, the label can be found on the left side wall, approximately at the level of the middle shelf or slightly below. This is user-friendly as it does not require tilting or dismantling the drawers. The sticker can be glued directly to plastic or to a metal surface if the inner chamber is made of stainless steel.
However, do not limit yourself only to the left wall. In some series, especially built-in models or refrigerators with the NoFrostsystem, the marking is shifted to the right wall or even to the upper part of the inner chamber, closer to the ceiling. Inspect carefully the entire surface of the sides, running your hand along the plastic - sometimes the sticker can be partially covered by shelf guides or bottle holders. If you are removing shelves for washing, be sure to check the space underneath them.
⚠️ Attention: Do not try to peel off or damage the manufacturer's label while searching. If the sticker is worn out or damaged, it will be almost impossible to restore the full code, and for the service center this can become a problem during warranty service.
Another area that is often overlooked is space behind the refrigerator door. Unlike washing machines, where the hatch opens, on refrigerators the label is sometimes glued to the end of the door or to the inner surface of the door itself, in the area of the seal. This is especially true for models with displays on the door, where there is simply no space for markings on the front part. Carefully move the rubber seal around the perimeter of the door - sometimes a narrow strip with a code is hidden there.
Searching for markings in the freezer compartment
If there are no searches in the main refrigerator compartment successful, the next logical step is to check the freezer compartment. The manufacturers' logic here is simple: if the space inside the refrigerator is occupied by a cooling system or compressor, the information is transferred to the freezer. Look for the sticker on side walls the freezer compartment. In models with the system NoFrost the space is limited by the evaporator, so the marking can be moved closer to the entrance or on the back wall if it is not occupied by technical holes.
Particular attention should be paid to models with a bottom freezer. In such cases, the label is often hidden under the lower drawer. You will need to remove the drawer completely (usually by pressing down on the latches or simply pulling it all the way) and look at the bottom of the niche or at the side rails. There may be either a main sticker with the full code or duplicate markings.
In some cases, especially in older models or specific series, information is applied to the inner surface freezer doors. This could be the end of the door or the space around the seal. It is also worth checking the area around the hole for the ice maker, if it is built into the design. Technical passport the device always duplicates the information from these stickers, but if the paper version is lost, searching inside the freezer becomes a priority.
- 🔍 Check the left and right side walls of the freezer at eye level.
- ❄️ Remove all drawers and baskets to access the bottom sections and guides.
- 🚪 Inspect the ends of the doors and the inside surface of the freezer door.
- 💡 Use a flashlight, as the depths of the freezer may be dark and the sticker may be small.
Hidden areas: base, rear wall and compressor
When the internal cameras do not contain the required information, you have to move on to an external inspection of the unit. One of the classic, although not the most convenient, places is the back wall refrigerator. To see the sticker, you will have to move the refrigerator away from the wall. The markings are usually located at the top or middle of the metal housing, near where the power cord or piping exits. Be careful: the back wall can be hot if the compressor is running.
Another common location for modern built-in models is base panel (the lower removable bar at the very bottom of the refrigerator). Manufacturers strive to make visible parts of equipment perfectly clean, so they hide all technical data down. You will have to remove the decorative panel (usually it is held on by latches or magnets) and look at the refrigerator body above the floor or at the inside of the removed panel itself.
⚠️ Attention: When removing a base panel or moving a heavy refrigerator, follow safety precautions. Do not pull sharply on wires and hoses if they approach the bottom of the unit, so as not to damage the water supply system or electrics.
It is also worth mentioning the zone compressor. On some models, an additional label with refrigerant specifications and pressure may be located directly on or near the compressor housing. Although the main model code is less common there, sometimes it is there that you can find the engine serial number, which indirectly helps in identifying the year of manufacture if the remaining labels are destroyed.
What to do if the refrigerator is built into a furniture set?
If the refrigerator is built-in, access to the back wall and base may be difficult. In such cases, try to find the marking on the end of the open door or use a long-handled mirror to look into the lower gap between the furniture and the floor without dismantling the equipment.
Decoding the E-Nr code and serial number
Having found the sticker, you will be faced with a set of letters and numbers that can confuse an unprepared person. The most important line is E-Nr (German Einsatz-Nummer). This is the article number of your model. It usually consists of 10 characters separated by a period (for example, KGV39AL30R). It is this code that must be entered on the manufacturer’s website or reported to the operator when ordering spare parts. The first few characters indicate the series and type of device, and the subsequent ones indicate a specific modification, color and sales region.
In addition to E-Nr, the label contains Fd (German Fabrikationsdatum) — production date. It is encrypted as an eight-digit number. The first two digits are the year of issue (for example, 15 — 2015), the next two are the month (for example, 09 — September). The remaining numbers indicate the day and shift. Knowing the production date is important, since in different years the same model could use different compressors or types of refrigerants.
Below is a table that helps you navigate the main designations that can be found on the nameplate of a Bosch refrigerator:
| Designation | Description | Example value | What is it for |
|---|---|---|---|
| E-Nr | Model number | KGN39AI30R | Ordering spare parts, searching for instructions |
| Fd | Production date | 15090001 | Determination of the age of equipment |
| FDST | Add. date code (rare) | 1509 | Duplicate release date |
| S-Nr | Serial number | 00012345 | Warranty identification |
| V | Voltage | 220-240V | Checking the electrical network |
It is important to distinguish between model and serial number. The model (E-Nr) is the same for thousands of refrigerators of the same series produced, and the serial number is unique for each specific instance. When ordering parts, they most often require E-Nr, since spare parts are selected according to the design of the model, and not according to the unique number of your device.
Digital ways to search for a model without a sticker
In the era of Internet of Things (IoT), searching for information about technology is becoming easier. If the physical sticker is destroyed, erased, or inaccessible, you can try to find the data through digital services. Many modern Bosch refrigerators support Wi-Fi connectivity and are controlled via an app Home Connect. If your refrigerator was previously connected to this application, information about the model and serial number may be saved in the device profile on your smartphone or in a cloud account.
Also worth checking email. If you bought a refrigerator online or registered it on the official website to receive an extended warranty, a receipt or registration confirmation may remain in the email archive, where the full model code is indicated. Search for the keywords "Bosch", "Garantie" or "Registration". This is an often overlooked, but very effective method.
Another option is search by photos. Remember, did you take photos of the kitchen or the refrigerator itself in the first days after the purchase for social networks or reports to the craftsmen? When you zoom in on a high-quality photo of a front panel or an open door, you can sometimes make out part of the nameplate even if it was not in focus. Modern image search algorithms can also help identify a model by appearance, although this method is less accurate.
- 📱 Check the connection history in the Home Connect application.
- 📧 Look for emails confirming purchase or registration.
- 📸 Analyze old photographs of the refrigerator in high resolution.
- 💳 Check bank statements for the date of purchase - the transaction description sometimes indicates the product article.
What to do if the marking is completely lost
The situation when the sticker burned in a fire, torn off by previous owners or completely unusable, is difficult, but solvable. In this case, you will need help professional technician. A Bosch service technician can identify the model by its internal structure: compressor type, evaporator configuration, control board model and housing design features. Each part has its own code, and their combination indicates a specific model of the refrigerator.
For an independent identification attempt, you can try to find the code on control board. If you have the skills to disassemble equipment (and you have unplugged the refrigerator!), you can remove the top cover or back panel and inspect the electronic units. The boards are often marked with stamps indicating compatible models or version codes, which can be entered into a search engine along with the word "Bosch".
⚠️ Attention: Self-disassembling the refrigerator to search for codes on the board can lead to loss of warranty and violation of the tightness of the cooling system. If you are not confident in your abilities, it is better to call a specialist for diagnostics.
You can also contact an authorized service center with a request to carry out troubleshooting. The technician will arrive, inspect the unit and use the internal components to determine the exact defect
