The unique solution:
The auto 3 in 1 system from Bosch*
Dishwashers fitted with this system adapt the washing process to
suit the cleaning product used. This makes it possible for water
consumption during the intermediate washing cycle to be reduced
and the temperature at the rinsing stage to be increased. Unlike with
models made by other manufacturers, this is automatic, so it is no
longer necessary for the customer to activate and/or deactivate a
special switch if they wish to use a combination cleaning product.
