Bosch washing machines model numbers explained decode 2014-2024

The production of garment care appliances is a key activity within the Bosch-Siemens Group’s Household Appliances Division. Each Bosch washing machine, like all household appliances, comes with a model number. This model number provides specific information about the washing machine.

Model number structure of Bosch washing machines

The model number structure of Bosch washing machines has evolved several times over the past decade. At first glance, the changes may seem insignificant, but there are notable differences, particularly in the number of characters in the model numbers. Here are a few examples:

• WGG244F90
• WUU28T92
• WGG244ZR90

The model number contains four blocks that encode specific information about the washing machine:

1. Appliance Type Block: This block indicates the type of appliance.
2. Technical Block details the housing, controls, and spin speed.
3. Design Block: This block indicates the color of the washing machine, typically the door color.
4. Country Block: This block indicates the country for which the washing machine is manufactured. This block is not used in the model code of washing machines for Germany.

The model number structure of Bosch washing machines has changed several times, resulting in various types of model numbers. Here are the main points when these changes took place:

• 2018: Model numbers were standardized, and some feature designations, such as the ability to connect to a smart home system, were removed from the model number.
• 2022: A modification number was added to the model number, effectively serving as a revision number for the washing machine on the same chassis. To maintain the structure of the number, the spin speed is now indicated by a single symbol.

It’s important to note that even in 2024, washing machines based on chassis from before 2022 are still being produced. Below are a few variations of the model number depending on the year:

• Before 2018: Model numbers include all features, including smart home connectivity.
• 2018-2022: Standardized model numbers without some feature designations.
• Post-2022: Model numbers include a modification number and a single-symbol spin speed indicator.

Bosch washing machine model number from 2018

Compared to newer model numbers, this model number has no model ID and the spin speed is indicated by two characters. This model number is still in use today.

I will not repeat myself with the explanation of similar symbols, I will stop only on the designation of spin speed in these model numbers, here is how the values can be interpreted
20: 1000 RPM
24: 1200 RPM
28: 1400 RPM
32: 1600 RPM

Otherwise there are no differences with the newer models.

The model number of an old Bosch washing machine

Until 2018, Bosch washing machine model numbers attempted to include features such as the ability to connect to Home Connect (Bosch smart home system) in the model numbers. However, over time, this labeling was abandoned for two reasons: Most washing machines include this feature by default, but some just don’t need it, so they don’t pay attention to it. In these models, the spin speed was indicated by a single symbol:

0: 1000 RPM
4: 1200 RPM
8: 1400 RPM
2: 1600 RPM
