8 Maintenance and care
Warning
Do not spray the machine or direct vicinity (walls and floor) with a water hose, steam jet or high-
pressure cleaner.
When cleaning the floor, take care to avoid flooding the substructure of the machine, in order to
prevent the uncontrolled entry of water.

An evacuation program is helpful on cleaning the machine. It can be interrupted at any time, for example to
also clean the machine interior manually (7.1.4). If it is not interrupted, it will run automatically and terminate
