Differences between Bosch washing machine series

If you’re choosing a Bosch washing machine, you’ve probably noticed that the manufacturer divides its machines into series 2, 4, 6, and 8 for 2024. However, the descriptions can be confusing, especially when footnotes indicate that certain features are missing from some models. The differences between the series lie in a few key factors, which we’ll explore in this article.

Bosch Series 2 Washing Machines

The Series 2 washing machines are of the classic type. Add detergent to the compartment, load your laundry, set the program, and the machine handles the washing. This series includes the standard models of the J (WAJ) and E (WGE) series.

  • WAJ: The chassis code on which the washing machine is built, representing the standard model introduced in 2020.
  • WGE: The latest 2022 revision of the E series has been available since 2012.

Following the latest update, these washing machines are equipped with new brushless motors and offer functionality reminiscent of early 2000s models.

Bosch Series 4 Washing Machines

These machines are similar to the Series 2 models, with the primary difference being that they are built on the newer 2020 AN (WAN) chassis, and some models use the 2021 GG (WGG) chassis. To differentiate these washing machines, they feature a large display that shows settings and washing stages.

The Series 2 and 4 washing machines are budget-friendly options manufactured in Bosch’s overseas factories.

Bosch Series 6 Washing Machines

The Series 6 washing machines are built entirely on the 2021 WGG chassis. This series is distinguished by additional features that vary significantly depending on the model. These machines may include special washing programs and advanced functions such as i-DOS (automatic detergent dosing) and Home Connect (smartphone connectivity). When choosing a washing machine from this series, it’s essential to pay attention to all the available features. These machines are also manufactured in Bosch’s overseas factories.

Bosch Series 8 Washing Machines

The Series 8 washing machines are built on the new 2022 WGB chassis, and most of them are manufactured in Germany. Despite their high-end production, the functionality of Series 8 machines is similar to that of the Series 6 models. Additionally, Series 8 includes models from previous generations, such as the WAX and WGA, which are discontinued but still available in some warehouses.


Despite the series classifications, there is no strict differentiation between what distinguishes one series from another. Therefore, when choosing a washing machine, you will need to carefully study all available models. Considering that stores still sell discontinued models from 2018-2020, this can be quite challenging.
