Modern washing machines are equipped with advanced self-diagnosis tools. In most cases, they are ready to tell us about all the malfunctions that occur on board. To do this, many machines are equipped with liquid crystal or LED displays, on which, in the presence of a breakdown, fault codes are displayed.
In this article, we decided to tell you about the errors of the washing machine of this brand, and in our other articles you can read Bosch washing machine reviews.
The error codes presented in the table are valid for all modern washing machines manufactured under the Bosch brand. Using this table, you can quickly find out what happened to your equipment.
