• For drinking water with carbonate hardness in
excess of 5 °dKH, a WMF water filter must be fitted;

is turned off and the main water supply tap is
switched off or the mains plug is unplugged.
• We recommend damage prevention measures such
as:
- installation of a suitable water monitor in the

running the cleaning program at least twice before
reusing the machine.
