Owners of German equipment are often faced with the need to find out the exact name of their device, whether purchasing spare parts, searching for instructions or calling a technician. Identifying the Bosch refrigerator model is the first and critical step, without which it is impossible to order a compatible part or check the compatibility of accessories. Unlike some brands, where the name is prominently displayed, Bosch has key information hidden in the technical code.
Many users mistakenly believe that it is enough to know the series or appearance of the device, but the lines Bosch Serie 4 or Serie 6 include dozens modifications with different compressors and control systems. That is why unique E-Nr is the only reliable identifier that guarantees the accuracy of the selection. Ignoring this code often leads to the purchase of unsuitable filters or shelves.
In this article we will look in detail at where exactly the manufacturer placed the information sticker, what it looks like and what the mysterious letters and numbers in the code mean. You will learn to distinguish between old and new labeling formats, and will also understand why knowing the year of manufacture can be a decisive factor when searching for documentation.
Where is the data sticker (nameplate)
Finding the manufacturer's label is not always a trivial task, since manufacturers often change its location depending on the year of manufacture and type of design of the refrigerator. In most modern models technical data sticker located inside the refrigerator compartment. Most often it can be found on the right side wall, closer to the shelves or in the recess above the top drawer.
If there is no label on the side wall, carefully inspect the inside of the door. It can be glued to the inner end of the door or on a decorative strip that hides the hinges. In rare cases, especially in built-in models, the nameplate is hidden behind the base or on the rear wall of the case, which requires moving the unit away from the wall.
⚠️ Attention: Do not try to peel off the sticker if it is difficult to read. It is better to carefully photograph it in good lighting or rewrite the code manually, since re-sticking it may lead to the loss of important information about the refrigerant.
To make the search easier, you should check several standard zones, since the location depends on the specific series:
- 📍 On the inner wall of the refrigerator compartment (on the right or on the left).
- 📍 At the inner end of the refrigerator or freezer door.
- 📍 Behind the decorative panel above the top drawer (requires removal of the shelf).
- 📍 On the back wall of the case (typical for older models).
Structure and decoding of the code E-Nr
The most important marking element is the code E-Nr (or simply Nr), which is a combination of letters and numbers. This code consists of two main parts: a letter prefix indicating the device type and series, and a numerical suffix indicating the specific modification and year of production. For example, the code may look like KGN39XI30R/01.
The letter part (for example, KGN) tells us about the type of refrigerator: K means refrigerator, G - with a freezer at the bottom, N - NoFrost. The numbers following the letters (39) usually indicate the width of the device in centimeters. The remainder of the code contains information about color, handle design, type of control and country of assembly.
Numeric part after the slash (/01, /02, /03) is critical for the compatibility of electronic boards and compressors. Even if the main code is the same, a difference in this index may mean that the refrigerator has a different firmware version installed or the component supplier has changed.
Determining the year of manufacture by serial number
Often there is a need to find out not just the model, but year of manufacture of the refrigeratorto estimate its age or find the appropriate instructions. This information is encoded in the serial number (FD), which is usually located just below or next to the E-Nr code. The serial number consists of an alphanumeric combination, where the first two digits or a letter and a number indicate the production date.
The coding system has changed over time. In older models (up to about the 2000s), the year was indicated by a single number, and the month by a letter. Newer ones use a two-digit year designation. To accurately decipher the date, you need to know the encoding system that was in effect during the production of your equipment.
| Position in the code | Designation | Example (Old format) | Example (New format) |
|---|---|---|---|
| 1st character | Year (last digit) | 9 = 2009 or 1999 | 1 = 2021 or 2011 |
| 2nd character | Month (A-L) | A = January, B = February | A = January, B = February |
| 3-4 characters | Day of the month | 01-31 | 01-31 |
How Find out exactly the year if the code is hard to read?
If the sticker has worn off, try to find a warranty card or purchase receipt. Also, the year of manufacture is sometimes indicated in the service book or on the box if you saved it. As a last resort, you can contact Bosch support by calling the full code E-Nr.
Differences between Bosch series (Serie 2, 4, 6, 8)
Understanding the series of your refrigerator helps you quickly navigate the functionality and energy class. Bosch clearly segments its products, and series definition is often possible even by appearance and basic characteristics specified in the model code.
Series 2 (formerly Classixx) are basic models with a minimalist design and a standard set of functions. They are reliable, but lack advanced climate zoning systems. Series 4 offers improved design, often glass shelves and system NoFrost in both chambers. Series 6 and 8 are premium solutions with touch controls, VitaFresh freshness zones and intelligent cooling systems.
Visually, the series differ in the design of the handles, the presence of a display on the door and internal lighting. However, you should not rely only on appearance, since the equipment could change over the years. The exact belonging to the series will be confirmed only by deciphering the first letters of the model code.
What to do if the sticker is lost or unreadable
The situation when the nameplate is damaged, peeled off or worn down to the point of being unreadable is not uncommon, especially in refrigerators that have been in use for more than 10 years. In this case, model identification becomes a complex task requiring indirect methods.
The first thing you can do is to examine the technical passport of the device, if it has been preserved. The full model code is always indicated there. If there are no documents, try to find a box from the refrigerator - it also has duplicate markings. As a last resort, you can try to determine the model by appearance and characteristics through online catalogs, comparing the location of shelves, type of handles and dimensions.
⚠️ Attention: Do not use approximate codes to order expensive spare parts, such as a compressor or electronic module. An error in one number can lead to the part not fitting into place or burning out when connected.
If the visual search does not produce results, the last option remains - disassembly. Sometimes a duplicate sticker or stamping with a code may be on the compressor housing or on the rear metal wall, but to access them you may need to remove the protective casing.
☑️ Actions in case of a lost sticker
Using the code to search for documentation and spare parts
Once you have succeeded determine the exact model, you have access to the full range of service support. Knowing the E-Nr code, you can go to the manufacturer’s official website or specialized spare parts portals and download the original diagram of the device.
This is especially useful when searching for water filters, shelves, drawers or rubber seals. Plastic interior elements often change shape in different modifications, and even a millimeter mismatch of fasteners will render a new part useless. The model code ensures that you are ordering the exact drawer that will fit perfectly into your refrigerator.
Also, the exact model is necessary to find software updates if your refrigerator supports Smart Home or has an electronic display. Firmware designed for one modification may not work correctly on another, even within the same series.
Is it possible to use a model code from a similar refrigerator?
It is strictly not recommended. Even visually identical refrigerators may have different mounting systems, refrigerant types, or electrical circuits. Using the code of a “neighboring” model will lead to errors in selection.
Where else can the model code be duplicated?
The code can be indicated on the purchase receipt, warranty card, on the refrigerator box, and sometimes (in rare cases) on the inside of drawers or shelves if they are individually marked.
What does it mean if the code starts with KGV?
The KGV prefix usually indicates a model with a freezer at the bottom (V - Vertikal), but without a NoFrost system in the refrigerator compartment (a drip defrosting system is often used). This is an important nuance when searching for parts of the water drainage system.
How to find out the model if the refrigerator is built into the furniture?
If access to the side walls and door is limited by furniture facades, try looking into the lower ventilation grille (base). Sometimes a sticker is put there. In extreme cases, you will have to carefully move the set or remove the top panel of the cabinet.
