Rinse the filter with clean water.Rinse the inner and outer holes
of the portafilter with clean
water, and be warned that do
not wash the portafilter with
any descaler.
Soak the portafilter in hot water
for 10 minutes(do not clean or
soak the portafilter in any desc-
aling solution).
Put the portafilter back to the m-
achine for next use.
If 60 minutes are
notlong enough in
step 4, let the desc-
aling solution soak
the limescale for 3
days instead. Other
steps are the same.

coffee grinds, or too less
tamping force.
Weak coffee
Change to medium- or dark-roasted
coffee beans and if you use light-roa-
sted coffee beans, the final coffee will
be lighter in both its color and flavor.
A deep descaling is needed for your
machine, refer to the "Descaling
Cycle " section of "9.1 Cleaning &
Maintenance - Brewer" on page 32.
