If you have installed the Brita descaling system
WF 040-020 between the water supply and the
appliance, change the filter cartridge regularly.
Set the option “filter available” in the basic settings.
The appliance calculates the capacity of the filter
cartridge depending on the entered water hardness
and the use. Shortly before you have to change the
filter cartridge, a symbol appears on the display
every time you switch on the oven. This symbol
shows the remaining capacity of the filter cartridge.
If the filter capacity has expired, the symbol is
shown constantly on the display if the appliance is
on. Change the filter cartridge.
Reset the filter capacity symbol in the basic
settings after changing the filter cartridge.
Note
Depending on the preset water hardness and the
operating modes used, the symbol to change the
filter cartridge may not appear on the display for a
long period of time.
The manufacturer of the descaling filter recommends
to change the filter cartridge at least once a year for
hygenic reasons irrespective of the water hardness.
