Problem
I cannot activate the
AquaClean water filter
and the machine asks
for descaling.
The new water filter
does not fit.
The machine is making
a loud noise.
Cause
The filter has not been
installed or replaced in time
after the screen shows the
AquaClean reminder. This
means your machine is not
anymore completely
limescale free.
You are trying to install
another filter than the Philips
AquaClean water filter.
The rubber ring on the
AquaClean water filter is not
in place.
It is normal that your machine
makes some noise during
use.
The AquaClean water filter
was not prepared properly
and air is now drawn into the
machine.
The water tank is not fully
inserted and air is drawn into
the machine.
Solution
Descale your machine first and then
install the AquaClean water filter.
Only the Philips AquaClean water
filter fits into the machine.
Place back the rubber ring on the
AquaClean water filter.
If the machine starts to make a
different kind of noise, clean the
brew group and lubricate it (see
'Lubricating the brew group').
Remove the AquaClean water filter
from the water tank and properly
prepare it for use before you place it
back. See chapter 'AquaClean water
filter' for step-by-step instructions.
Make sure the water tank is in the
correct position: remove it and insert
it again pushing it as far as possible.
