How to find out the model and serial number of a Bosch refrigerator

Owners of German household appliances are often faced with the need to find the exact marking of their unit, especially when they need to order a rare spare part or download the latest instructions. Bosch refrigerator model is not just a set of letters, but a unique identifier that contains information about the year of manufacture, color, type of control and even the country of assembly. An error in one number can lead to the fact that the purchased part simply will not fit your device, and time will be wasted.

Many users look for the number only on the outer packaging or in the warranty card, forgetting that these documents are often lost or thrown away immediately after unpacking. However, information about E-Nr (model number) and FD (production date) does not disappear anywhere, it is securely attached to the case itself. In this article we will analyze in detail all the possible locations of information plates for different series of equipment.

There are several standard areas where manufacturers place nameplates, but each brand has its own preferences. Bosch equipment is characterized by a certain consistency in the location of labels, which greatly simplifies the task. The most reliable way is to look for a metal or paper sticker directly on the case, and not rely on memory or receipts. Let's look at the main places where you should look first.

Main locations nameplate with number

The first place where you should pay attention is the inside of the refrigerator compartment. Bosch engineers most often place an information plate on the side wall inside the compartment. Usually it is located on the left, approximately at the level of the bottle shelves or slightly higher. If there is not enough space on the left, the label can be moved to the right wall or even to the inside of the door, if the design allows.

The second popular place is the base part of the unit, located at the bottom of the front panel. There is often a ventilation grille on which the sticker is attached. To view the lettering, you may have to sit down or even remove the decorative panel if it is removable. This is typical for built-in models, where access to the side walls is limited after installation in a niche.

The third option, which is less common, but does exist, is the rear wall of the refrigerator. If you do not find the number inside and on the base, carefully move the refrigerator away from the wall. A silver or white label with full technical data may be affixed to the back metal surface, often at the top or middle part.

⚠️ Warning: Never try to pry off the nameplate with a knife or sharp object to remove it. The plastic may crumble and the number will become unreadable. It’s better to take a photo of it on your phone.

Finding the number may take some time, especially if the refrigerator is built into the kitchen unit. In such cases, access to the side walls is closed, and the rear part is difficult to check without completely dismantling the equipment. Therefore internal chamber and lower base remain priority areas for inspection.

What the Bosch marking looks like and what it means

Having found the sticker, you will see a lot of numbers and letters that can confuse an unprepared person. The most important parameter is E-Nr (or simply Nr). This is the model article number, which consists of 10 characters separated by a space after the fourth character (for example, KGN39XI30R 01). It is this code that needs to be entered into the search bar on the manufacturer’s website or in spare parts stores.

The number is usually indicated below or next to the model number. This is a four-digit production date code. It is critically important for determining the age of equipment, since the compatibility of many electronic components depends on the year of manufacture. For example, compressors in models before and after 2010 may have different seats. FD number. This is a four-digit production date code. It is critically important for determining the age of equipment, since the compatibility of many electronic components depends on the year of manufacture. For example, compressors in models before and after 2010 may have different seats.

Also on the label is PZ-Nr a production number, which is unique for each specific instance that came off the assembly line. It is used by service centers to track repair history. For the average user looking for spare parts, it is less important than E-Nr.

Deciphering the FD code

The FD code consists of four digits. The first two digits are the year of manufacture (add 2000 to them if the code starts with 1, 2, etc.), and the second two are the month. For example, FD 9805 means May 2019 (calculation is based on the base of 1920 or simply 20 + 78 = 98, but for modern models it is simpler: 2000 + the first two digits if they are less than 20, or 1900+ if more, but in Bosch it is usually just 2000 + the number if it is the 21st century). More precisely: you need to add a constant to the number FD, but it’s easier to remember that FD 80... is 2000, FD 90... is 2010, FD 01... is 2021.

It is important to distinguish between the commercial name of the model and its technical index. On the price tag in the store, the refrigerator may be called Bosch Serie 6 VitaFresh, but to find parts you need an alphanumeric designation. Commercial names often change depending on the region of sales and the policies of retailers.

Search instructions for built-in refrigerators

Searching for markings in built-in Bosch appliances is associated with additional difficulties due to the tight installation in a kitchen niche. Access to the side walls is often blocked by the walls of the cabinet, and the back is pressed against the wall. However, engineers have taken this into account by placing labels in accessible areas.

First of all, check the end of the refrigerator door. Open the door and carefully inspect the vertical end. Often, where the hinges are located or, conversely, on the side of the handle, a narrow nameplate is glued. If it's clean, look inside at the side wall, but not at the shelf, but at the metal of the case.

If there's nothing inside, your next step is the bottom ventilation grille. For built-in models, it is often hidden behind the decorative panel of the kitchen facade or located at the very bottom of the plinth. You may need a flashlight, since there is usually no lighting in the niche.

In some cases, if the refrigerator is installed in a deep niche, the only way to see the back wall is to partially dismantle the equipment. This requires caution: it is necessary to turn off the power, free up space and carefully pull out the unit without damaging the floor covering.

Deciphering the production date by FD number

Determining the exact production date is necessary not only to assess the age of the equipment, but also to select compatible filters, lamps and seals. The code FD (Fabrication Date) is the key to this information. It consists of four digits, and its decoding is quite simple if you know the algorithm.

For models released in the 21st century, you need to add 20 to the first two digits of the FD code. For example, if the code starts with 95, then 95 + 20 = 115? No, the system here is a little different. For modern refrigerators (after 2010), 2000 is often added to the first two digits, but there is a nuance with “zero” years. A more accurate method: if the first two digits are greater than 20 (for example, 98), then the year of manufacture is 2020 + (number - 80) or simply 2010s. It’s easier to remember: FD 90... is 2010, FD 91... is 2011, FD 98... - 2018, FD 99... - 2019, FD 01... - 2020, FD 02... - 2021.

The second two digits indicate the month of manufacture. 01 - January, 12 - December. Knowing the month and year, you can determine whether the warranty is still valid or approximately when a resource unit, for example, a compressor or NoFrost system, could fail.

⚠️ Attention: The algorithm for calculating the year may differ slightly for very old models (before 2000), but for the vast majority of Bosch refrigerators in operation, the rule “90s = 2010s, 00s = 2020s” works flawlessly.

What to do if the sticker is missing or worn off

Situations when the nameplate is missing are rare, but they are possible. The label could have come off during careless transportation, been removed by previous owners, or simply faded and become unreadable over years of use. In this case, there is no need to panic; there are alternative ways to solve the problem.

The first option is to look for documents. The model and serial number are often written down when selling. Also, the number must be on the factory record warranty card or operating instructions (on the first page or on the insert) the model and serial number are often included when selling. Also, the number must be on the factory cardboard boxif you saved it. It can be printed on the end in the form of a barcode.

If there are no documents, you can try to find information in your personal account on the manufacturer’s website if you have previously registered the equipment. Also, the model number is sometimes duplicated on the purchase receipt or on a bank statement if payment was made by card, although only the commercial name may be indicated there.

As a last resort, if repairs are needed, you can call a technician for diagnostics. A specialist in the characteristic components, defrosting system and appearance of the compressor can often determine the series and necessary spare parts visually, without an exact number.

Why do you need an exact model number during repairs

Many owners underestimate the importance of an exact match of the model, believing that “a refrigerator is a refrigerator.” However, in the production of household appliances modifications they may differ in critical details. For example, one series of refrigerators may use different types of thermostats, fans or control boards.

When ordering a sealing rubber from a photo, you can make a mistake with the thickness or profile of the magnetic insert. When ordering a compressor, you may not take into account the type of refrigerant (freon R600a or R134a), which will lead to incorrect operation of the system or even an explosion. The model number eliminates these risks.

In addition, the exact E-Nr allows you to download original circuit electrical wiring specifically for your device. This is indispensable for complex electronics repairs, when you need to ring a specific contact or replace a blown fuse of a certain rating.

Frequently asked questions (FAQ)

Is it possible to find a Bosch refrigerator model on the Internet without access to the case?

Unfortunately, it is impossible to determine the model remotely, since serial numbers are not publicly linked to IP addresses or user accounts in the public domain. The only option is to find receipts, a warranty card, or contact the store where the purchase was made if customer data has been saved.

What does the ZE code on the label mean?

The ZE code (or Z.E.) usually indicates the software version number or unit modification, but for searching for basic spare parts it is secondary. The main thing remains E-Nr. However, when ordering electronic control boards, the ZE code may be important to clarify the revision.

Where is the number located on Bosch refrigerators of the Maxx or Classixx series?

For the old Maxx and Classixx series, the nameplate was most often located inside the refrigerator compartment on the right wall or on the base grille in front. The search principle is no different from modern models.

Can the model number be on the outside of the door?

The model number is almost never placed on the outside of the door so as not to spoil the design. The exception is some older models, where a small sticker could be on the end of the door in the hinge area, but this is rare for Bosch.

What to do if the store says that a model with that number does not exist?

Check that the entry is correct. The letter "O" and the number "0", or the letter "B" and the number "8" are often confused. Also make sure that you enter the E-Nr and not the FD or PZ number. If the number is correct, but the model is not in the database, perhaps it was produced for a different region.
