The production of appliances for clothes care is one of the Bosch-Siemens Group’s main lines of business in the home appliance division. As with all appliances, Bosch washing machines have a model number; you should know that the model number tells you some information about the washing machine.

There is also information in the washing machine’s serial number; for example, you can tell the date of manufacture from the serial number; I talked about this in the article “Bosch and Siemens Serial Number”.

Bosch washing machines can be described as thoughtful, user-friendly appliances. The disadvantages can include the cost of post-warranty maintenance of the devices; in case of a breakdown, the repair cost can reach more than half of the cost of a new washing machine. This is due to the concerned policy to support the product during operation.

Bosch washing machine models

Bosch washing machine model numbers. The washing machine model number indicates some technical characteristics type of washing machine; you can find out what generation the washing machine belongs to. Since one model of the washing machine has been produced for several years, new models of washing machines can be both an upgrade of previous models and a new product.

New Bosch washing machine model number

In 2018, there was a change in the structure of the Bosch washing machine model number. In most cases, the model number I have given in the figure is used. The model number defines the following parameters: product type, technical features, generation, spin speed, control type, design (this is usually the color of the cabinet and the hatch), and the country for which the washing machine is made.
