How to determine the year of manufacture of a Bosch refrigerator: decoding the serial number and other methods

Determining the year of manufacture of a refrigerator Bosch is a problem that owners face when buying used equipment, planning repairs or selecting spare parts. The production date affects warranty obligations, component compatibility, and even the power consumption of the model. Unfortunately the manufacturer does not indicate the year of manufacture in a visible place, but it can be calculated by indirect signs.

In this article we will analyze all the available methods - from deciphering the serial number to analyzing design features. You will learn where to look for factory markings, how to read the encoding Bosch/Siemens, and what to do if the data sticker has worn off. We will pay special attention to the nuances for models released after 2010, since the designation system has changed.

If you plan to sell a refrigerator or select original parts for it, knowing the exact year of manufacture will save time and money. For example, compressors or electronic boards for models 2015 and 2018 may differ even if they have an identical appearance.

1. Bosch refrigerator serial number: structure and decoding

The main way to determine the year of manufacture is to study serial number (Serial Number, S/N), which is printed on the nameplate. U Bosch it consists of 12–14 characters and contains encoded information about the production date. The format of the number depends on the year of manufacture of the equipment:

For models produced until 2010, the system was used FD-XXXX-XX-XXX, where the first two letters indicated the plant, and the third and fourth digits - the year (for example, FD05... = 2005). After 2010, the company switched to a unified standard BSH Group (includes brands Bosch, Siemens, Gaggenau), where the year is coded differently.

Modern serial numbers (after 2010) look like:

85 12 3456789
│ │ └─ unique identifier
│ └─ week of production (12th week)
└─ year of production (8 = 2018, 9 = 2019, 0 = 2020, etc.)

Example: number 85123456789 stands for 12th week of 2018 (March 2018). To avoid mistakes, check the correspondence table below.

2. Where to look for the serial number on a Bosch refrigerator

The serial number plate may be located in several places. Inspect the refrigerator in the following areas:

• 📌 Inside the chamber: on the side wall (usually on the left), ribbed panel or under the shelf. Often the sticker is hidden behind the vegetable drawer.
• 📌 Back the case: on the top of the back wall, the compressor. You will have to move the refrigerator away from the wall.
• 📌 On the door: on the side or top, under the decorative overlay (relevant for models Bosch Serie 6/8).
• 📌 In the documentation: on the warranty card, in the product passport or on the box (if preserved).

On some models (for example, Bosch KGN39XL30R), the serial number is duplicated on electronic control board. To get to it, you will need to remove the top cover - this is risky without experience, so it is better to first look for the sticker on the outside.

⚠️ Attention: If the refrigerator is built-in (for example, series Bosch KIV87VS30), the serial number may be hidden behind the decorative panel. Do not try to remove it yourself - contact a specialist so as not to damage the fastenings.

If the sticker is worn off or missing, try to find the number. in settings menu (relevant for models with a display). To do this:

1. Press and hold the button Super Cooling (or Super Freezing) for 5 seconds.
2. In the service menu that appears, select the item Info or Version.
3. Scroll to the line S/N —the serial number will be displayed there.

3 Table of decoding the year of manufacture by serial number

For convenience, we have compiled a table of correspondence between the first digit of the serial number and the year of production. It is relevant for refrigerators Boschreleased after 2010:

Please note: from 2020 Bosch started use three-digit week code (for example, 045 instead of 45This is not an error - just an updated format.

For models until 2010 the logic is different: the year is encoded with the third and fourth digits after the letter prefix. For example:

• FD03... → 2003 year
• SG08... → 2008

⚠️ Attention: If the serial number begins with the letters FD, SG or WB, your refrigerator was manufactured before 2010. For an accurate decoding, contact an authorized service center. Bosch with a photo of the sticker.

4. Determining the year by refrigerator model

If the serial number could not be found, you can approximately determine the age of the equipment by model number. data-i="143">it consists of letters and numbers, where some symbols indicate the year of manufacture or generation of the equipment. Bosch it consists of letters and numbers, where some symbols indicate the year of manufacture or generation of the equipment.

Structure of the model number:

K G N 39 X L 30 R
│ │ │ │ │ └─ region (R = Russia/Europe)
│ │ │ │ └─ series (L = 2018–2020, M = 2021–2023)
│ │ │ └─ features (X = NoFrost)
│ │ └─ volume (39 = 388 l)
│ └─ type (G = two-chamber)
└─ line (K = refrigerator)

Key hint: the letter before the last two digits (in the example - L) often indicates a series that is tied to the year of manufacture. Decoding for popular series:

• 🔹 Series K (for example, Bosch KGE39...) - 2015–2017.
• 🔹 Series L (for example, Bosch KGN39XL...) - 2018–2020
• 🔹 M series gives (for example, Bosch KGM39...) - 2021–2023
• 🔹 Series N (For example, Bosch KGN39VN...) - 2026 and newer.

This method gives approximate date (accuracy ±1 year), but will help narrow the search range. For accuracy, combine it with serial number analysis or visual cues (see next section).

5. Visual signs: how to distinguish old models from new ones

If documents and stickers are lost, pay attention to design features the refrigerator. The manufacturer regularly updates design and technology, which helps to approximately determine the age of the equipment.

Features of models before 2015:

• 🔌 Mechanical control: rotary temperature controls (no touch buttons or display).
• 🟢 Illumination with incandescent lamps (in new models - LED).
• 🧊 Manual defrosting of the freezer compartment (no NoFrost or LowFrost system).
• 🔊 Loud compressor: a constant hum is heard (modern models are quieter).

Signs of models 2016–2020:

• 📱 Electronic control with a display or touch buttons.
• ❄️ NoFrost system or LowFrost (the freezer does not require defrosting).
• 💡 LED backlight in the main chamber.
• 🔋 Energy consumption class A++ (on the sticker inside the camera).

Features of models 2021 and newer:

• 🤖 Function Home Connect: control from a smartphone via Wi-Fi.
• 🌡️ Temperature and humidity sensors with automatic regulation.
• 🔇 Noise level below 38 dB (specified in the specifications).
• 🖥️ Color TFT display (in premium series, for example, Bosch Serie 8).
