You should know that BSH Hausgeräte GmbH owns the global brands Bosch, Siemens, Gaggenau, Neff and eight regional brands. This information is taken from the official Bosch Group website. This information applies not only to Bosch appliances but also to Siemens or Gaggenau.

In this article, I will look at how to decode the information sticker of Bosch home appliances. To give you an example, I will look at the label of a Bosch washing machine, from which you will learn the following information.

  • What the FD number is, 
  • The structure of the Bosch and Siemens washer serial numbers, 
  • How to find the model number and serial number of a Bosch washing machine.
  • How to determine the production date of a Bosch or Siemens washing machine. 
  • How to determine if a washer is a fake or a combination of several washers.
  • And how to find out where your Bosch washing machine was made.

Bosch washing machine model and serial number lookup

If you want to know the model code or serial number of a Bosch washing machine, you need to find information about the washing machine. You should know that Bosch and Siemens washing machines have two information stickers: a master sticker and a duplicate sticker. 

The main (large) information label: This is located on the rear panel of the washing machine. The manufacturer does not define the specific location, but is usually near the top of the washing machine.

This sticker contains extended information; I will give an example of such a sticker below. 

Duplicate sticker: has information (build date, serial number, model number) and is located inside the washing machine’s door; the information on both stickers must be identical. Note that the sticker is located on the inside of the laundry loading door. 

The logic in these stickers is clear: the information on the door is accessible and easy to find, the sticker on the back is hard to find, and you probably won’t need it. But if the information from the sticker on the hatch is not readable, you can always find the sticker on the back of the washing machine. 

Here is their location, which you can see in the picture below.

Example of a sticker for a Bosch washing machine

You may be confused if you need information about your washing machine and find an information sticker. You won’t see the model number (model code) or serial number; the information on the sticker will be a little different. Now, I will tell you how to correctly understand the information you will see on the sticker.

  • E-Nr. WAS28775/23: washing machine model
  • FD – (Factory Date): manufacturing date, 8907, consists of 4 digits; how to decipher the manufacturing date of the washing machine will be discussed below.
  • Z -Nr.: We will also look at the six-digit washing machine number 200430 and how to decode it.
  • 489070250386004303: the complete Bosch washing machine serial number contains information; where the washing machine is made and the date of manufacture.

Example decoding the serial number, FD, of a Znr Bosch, Siemens washing machine

In the picture, I have clearly shown how to understand the serial number of a Bosch washing machine and how to determine the production date of Bosch home appliances.

For this example, I have taken the information from the washing machine model WAS28775 sticker. As I said, FD (Factory Date): This is the production date of the washing machine 8907. This washing machine washing machine was manufactured in July 2009. Bosch encodes the production date; you will not see the production date month/year on the label. The production date information is in the FD number, and here is how you can find out the production date of the washing machine.

  • 8 is the decade code; in this case, the washing machine was manufactured between 2000 and 2009. Here is a short list of years
    • 0 – 2020 – 2029
    • 9 – 2010 – 2019
    • 8 – 2000 – 2009
    • 7 – 1990 – 1999
    • 6 – 1980 – 1989
    • 5 – 1970 – 1979
    • 4 – 1960 – 1969
    • 3 – 1950 – 1959
    • 2 – 1940 – 1949
    • 1 – 1930 – 1939
  • 9 – years in a decade, which means that the washing machine was manufactured in 2009.
    07 is the month the washing machine was manufactured, indicated by two digits.
  • 07 This washing machine was manufactured in July.

List of FD numbers and date of manufacture of Bosch/Siemens/Gaggenau appliances

I have compiled a table where you can easily find your FD number and determine when your washing machine was manufactured. And not just your washing machine, but any Bosch appliance in general. The table lists FD numbers from 1970 onwards, so I don’t think you’ll need to research older models of Bosch appliances.


Decoding Z-Nr Bosch, Siemens

If you want to know what Z NR is, the number of washing machines assembled on a particular assembly line in the current month. Here’s how you can explain this number
Z-Nr – 200430

  • 2 is the assembly line number
  • 00430 is the washing machine number and can be decoded as follows: In July 2009, this washing machine was 430 assembled on this assembly line. The five-digit designation allows us to assign 99999, 3225 washing machines per day, 134 per hour, and 2 per minute. It is impossible to produce such several machines on one conveyor, and five digits are enough to create an identification number. It is impossible to produce such several washing machines, but it is possible to produce, for example, many more coffee grinders; that is why a five-digit number is used.

Decode of the serial number of Bosch, Siemens washing machines.

The washing machine is also assigned a serial number containing additional information. The serial number is an additional protection introduced by the washing machine manufacturer. By the serial number, the correctness of information about the washing machine is controlled; in turn, the serial number consists of 18 digits 489070250386004303 and can be explained as follows.

It should be noted that washing machines manufactured before 2000 had no serial number. The manufacturer only provided the model number (E-NR), the year of manufacture (FD), and the washing machine number.

Now let’s see how to understand the entire Bosch serial number.

  • 48 is the code of the factory where the washing machine was assembled. The factory where the washing machine was assembled is assigned an individual code. This code can determine in which country the washing machine was assembled. Although nowadays, of course, it makes no difference where the washing machine was manufactured. Bosch factories have a unified quality system that ensures uniform quality of products.
    • 40 – Germany
    • 41 – Poland
    • 42 – Germany
    • 43 – Turkey
    • 45 – Germany
    • 48 – Germany
    • 84 – Thailand
    • 85 – USA
    • 87 – China
    • 88 – Russia
    • 99 – Germany

The following is a repetition of part of the FD number

  • 9 – the year of manufacture, the last year of the decade. The date of manufacture may be indicated in the FD number.
  • 07 – month of manufacture.
  • 0250386 – manufacturer’s internal code containing service information such as component suppliers.
  • 00430 – washing machine number
  • 3 – Serial number checksum code used to verify the correctness of the serial number.

Fake serial number, Bosch washing machine

Sometimes there are discrepancies between the serial number, FD codes and the washer serial number. As an example in the photo above. According to the FD and Z-Nr information, the washing mashine was produced in 2001 in May and came off the assembly line under the number 3545. According to the serial number, the washer was produced in 2001 in December and came off the assembly line under the number 90733.

This is a fake sticker, as discussed below:

  • The Z-Nr. number must be six digits.
  • The production date in FD and the serial number are different.
  • The Z-Nr code and the ZNR code in the serial number do not match.
  • Those who printed the sticker did not know that the serial number must contain FD and Z-Nr. information.

  1. שלום. מה אומר הגם הזה של מכונת כביסה בושש WAE24261IL. תודה רבה

    • I don’t know all the factory codes, there are a lot of them. The label should indicate which country the device is assembled in.

    • It’s not that important, Bosch has implemented a unified quality system in all of its plants.

  2. Thank you so much for this article! I recently bought a Bosch washing machine and I was curious as to when and where it was produced. Your article is the only one in the web (as far as I searched anyway) that thouroughly explains every single aspect of the serial code and helped me track down the actual date, assembly line and country of manufacture of my machine
