Problem
The AquaClean filter icon
does not appear on the
display after I replaced
the filter.
The AquaClean filter is
installed, but the
descaling message
appears.
The new water filter does
not fit.
Cause
The filter has not been replaced
in time after the AquaClean
filter icon flashed and the
capacity dropped to 0%.
You did not install the
AquaClean filter during first
installation, but after having
brewed approx. 50 coffees
(based on 100ml cups). The
machine has to be completely
limescale-free before you install
the AquaClean filter.
You did not activate the new or
replaced AquaClean filter in the
machine menu.
You did not confirm activation in
the machine menu.
You have not activated the
AquaClean filter in the machine
menu.
You are trying to install another
filter than the AquaClean filter.
Solution
Descale your machine first and then
install the AquaClean filter.
First descale the machine and then
install a new AquaClean filter. After
descaling, the filter counter is reset to
0/8. Always confirm filter activation in
the machine menu. Also do this after
filter replacement.
Descale your machine first. Then
activate the AquaClean filter in the menu
(see 'Activating the AquaClean filter').
Also do this when you replace the filter.
Confirm the activation of the filter in the
machine menu. (see 'Activating the
AquaClean filter') If the display shows
'START CALC CLEAN', you first need to
descale the machine. Remove the
AquaClean filter before descaling and
reinsert it afterwards.
First descale the machine and then
install a new AquaClean filter. This will
reset the filter counter to 0/8. Always
confirm filter activation in the machine
menu (see 'Activating the AquaClean
filter'), also after filter replacement.
Only the AquaClean filter fits into the
machine.
