Owners of high-quality German equipment are often faced with the need to identify their unit when ordering spare parts, issuing a warranty or calling a technician. The question of where to look for a Bosch refrigerator model becomes especially relevant when an exact match of characteristics is required when selecting components. Making a mistake in one digit of the code E-Nr means the risk of getting a part that does not physically fit your device.
Bosch engineers have provided several places to place identification information, but over time, labels can get lost, become dirty, or be accidentally damaged during transportation. In this article, we will analyze in detail all possible locations where the manufacturer places nameplates, and learn how to correctly read the data encoded in them.
It is important to understand that searching for a model is not just a formality, but a critical stage for further maintenance of equipment. The exact E-Nr code (for example, KGN39XI30R/01) is the only guaranteed key to finding original spare parts in the manufacturer's databases. Using only the series name or the appearance of the camera often leads to errors.
Main locations of the nameplate
The first and most obvious place to look is the interior of the refrigerator or freezer. Bosch engineers most often place an information sticker on the side wall inside the refrigerator compartment. This is convenient for the user, as it does not require moving the heavy unit away from the wall.
However, the location may vary depending on the year of manufacture and the specific series of the device. In some models nameplate it is mounted on the inside of the door, most often in its lower or middle part. Less common, but still encountered, is the option of placing a refrigerator on the ceiling, especially in models with a system NoFrost.
If there is no sticker inside the chambers, carefully inspect the back wall of the case. The nameplate can be affixed to a metal surface on the back, near the compressor or condenser. It can be difficult to get to it without moving the equipment, but this is the second most popular placement option.
⚠️ Attention: Never try to tear off the sticker with a knife or aggressive chemicals if it is dirty. Use a soft cloth and soapy water to gently clean the surface while maintaining the readability of the barcode.
Modern models often duplicate information digitally or use QR codes, but the physical sticker remains the main document. In rare cases, especially for built-in models, the plate may be located at the end of the door or even on the base panel below.
How to correctly decipher the E-Nr code
Having found the sticker, you will see a lot of numbers and letters, which can cause confusion for an unprepared user. The most important element here is the line designated as E-Nr (or sometimes just Nr). It is this code that contains complete information about the modification, color, country of assembly and production version.
The code usually consists of an alphanumeric combination, followed by a slash and several more numbers. For example, in the entry KGN39VW21R/01 the part before the slash indicates the series and basic configuration, and the numbers after the line (/01, /02, /03) indicate the production version. This is critically important, since in the same model, refrigerant types or electronic boards could change over time. compressors, refrigerant types or electronic boards.
Next to the model code there is often a serial number (FD or E-Nr in long format), which allows you to determine the exact date of manufacture. The first four digits of the serial number often encode the year and month of manufacture, which is necessary to calculate the warranty period. If the warranty is still valid, this data will be requested from the service center first.
The sticker also indicates technical parameters: volume of chambers, type of refrigerant (for example R600a), number of freezer stars and noise level. All this data must coincide with the passport data specified in the user manual, if it is preserved.
Search for the model in the documentation and on the box
If physical access to the sticker is difficult (the refrigerator is built into a kitchen unit or pushed tightly against the wall), documentation will come to the rescue. The warranty card, operating instructions or sales receipt always contain the exact model of the device. When purchasing in a store, this data is entered into the cash register and recorded in the receipt.
The packaging box, if you saved it, also carries all the necessary information. Large labels with barcodes and the full model name are usually stuck on the side edges of cardboard containers. This is especially convenient if the refrigerator has not yet been unpacked or, on the contrary, is planned for transportation and is already packed.
In the era of digitalization, many users save electronic copies of receipts or photographs of documents in cloud storage. Check your email or instant messengers: perhaps a photo of the warranty card taken on the day of purchase will help you quickly find the one you need E-Nr without having to go behind the unit.
The lack of paper documents is not a critical problem if you have access to your personal account on the website of the store where the purchase was made. The order history often stores the full specification of the product, including the manufacturer's part number. This can be a lifesaver when the sticker inside the chamber has faded and become unreadable.
Correspondence table of series and their features
Understanding the series of the refrigerator helps not only in selecting spare parts, but also in assessing its functionality. Different Bosch lines have unique characteristics that are encoded in the first letters of the model. Below is a table to help you navigate the main families of equipment.
| Series (beginning of code) | Refrigerator type | Key feature | Years of active production |
|---|---|---|---|
| KGN | Two-chamber (NoFrost) | Full NoFrost system, modern compressors | 2010 – present |
| KGV | Two-chamber (LowFrost) | LowFrost freezer, static cooling from above | 2008 – present |
| KDN | Two-chamber (NoFrost) | Budget line, basic functionality | 2012 – present |
| KIS/KIV | Built-in | Special fastening for furniture facades | 2005 – present |
Knowing your series, you can guess the type of defrosting system. For example, models require manual defrosting of the refrigerator compartment, while models are fully automated. This affects the selection of spare parts, such as defrost heaters or temperature sensors. KGV require manual defrosting of the refrigerator compartment, while KGN fully automated. This affects the selection of replacement parts such as defrost heaters or temperature sensors.
The series also determines the type of refrigerant and oil used. Old models could use the same types of freons, while new ones could use more environmentally friendly ones, but requiring a specific approach when refilling. For a technician called for repairs, knowledge of the series will tell a lot about the internal “stuffing” of the unit even before opening.
☑️ Check before ordering spare parts
Digital identification methods and smart functions
Modern “smart” Bosch refrigerators are equipped with Wi-Fi modules and support operation via the application Home Connect. If your unit is connected to the network, you can find its model directly in the mobile application interface. It displays the full name of the device, status and even error history.
On some new models, information about the model may be duplicated on a digital display located on the door. By long pressing the button combination, you can enter the service menu, where the full E-Nr and current software version will be displayed on the screen.
However, it is worth remembering that software methods are only good as long as the device is turned on and working properly. If the refrigerator does not turn on or the electronics fail, the digital method will not help. Therefore, the physical sticker remains the main and indisputable source of truth.
⚠️ Attention: The Home Connect application interface and menu functionality may vary depending on the region and firmware version. It is better to look for current instructions on entering the service menu in the official manual for a specific model.
The use of QR codes on new stickers allows you to instantly go to the product support page by scanning the code with your smartphone camera. This speeds up the process of searching for documentation and spare parts, minimizing the risk of errors when manually entering characters.
What to do if the sticker is lost or unreadable
The situation when the nameplate has been torn off by the previous owners, has faded beyond recognition or is covered in paint during a kitchen renovation is not uncommon. In this case, the search for a model turns into a detective story, but the chances of finding the answer are still high.
The first thing you can do is to carefully study the design features. Remove shelves, drawers and plastic trim. Sometimes additional marking stickers are glued to the back of the plastic elements, on the ends of the shelves, or even on the plastic of the freezer drawers.
The second option is to dismantle the rear cover of the compressor compartment (only for experienced users!). The compressor itself or the electronic control board often has its own factory markings with part numbers. Knowing the board or compressor number, an experienced technician can calculate the refrigerator model using cross-databases of spare parts.
The third, most reliable way in case of data loss is to contact an authorized service center with a photo of the internal device. Specialists in the characteristic components, type of evaporator and design can identify the series and select compatible analogs of spare parts, even if the exact E-Nr is unknown.
Frequent errors when searching and selecting
Many users make the mistake of trying to find spare parts by the name written in large letters on the front panel (for example, simply "Bosch" or "Maxx") This is absolutely not enough, since hundreds of modifications with different internal components are produced under one brand.
Another common mistake is ignoring the version after the slash. Models KGN39.../01 and KGN39.../04 are externally identical, but they may have different door fastenings, wiring connectors or board operation algorithms. Ordering a part without taking into account the version often results in the part not fitting into place.
Also, you should not rely only on the volume of the refrigerator. Different models may have the same displacement, but completely different geometry of the internal space and location of the mounting holes. The exact code is the only safe reference.
FAQ: Frequently Asked Questions
Is it possible to find a Bosch refrigerator model by the compressor serial number?
It is difficult to accurately determine the model of the entire refrigerator only by the compressor, since the same compressor can be installed in different series. However, this will help the technician understand the type of refrigerant and the power of the system, which will narrow the search.
Where is the label located in built-in Bosch refrigerators?
In built-in models, the sticker can most often be found on the inner end of the door (from the hinge side) or on the side wall inside the chamber, closer to the bottom. Sometimes it is placed on the base plate from below.
What does it mean if the code on the sticker is erased?
If the code is not readable, try illuminating the sticker with a bright flashlight at an acute angle - the relief of the letters may appear. If this does not help, you will need to visually identify the units by a specialist or search for purchase documents.
Why do you need the model version after the slash (for example, /01)?
This number indicates the production version. In different versions of the same model, the manufacturer can change suppliers of components (plastic, seals, electronics), so when ordering spare parts this parameter is critically important.
