10 DESCALING
Limescale normally builds up with the use of the appliance.
The machine needs descaling every 1-2 months (if used) and/
or whenever a reduction in water fl ow is noticed. Use the GAG-
GIA descaling solution only.
In case of confl ict, priority must be given to
what is indicated in the operation and mainte-
nance manual over the instructions provided on sepa-
rately sold accessories and materials.
Use the GAGGIA descaling
solution only. Its formula
has been designed to ensure bet-
ter machine performance and
operation for its whole operat-
ing life. If correctly used, it also
avoids alterations in the brewed
product. The descaling solution
is to be disposed of according to
the manufacturer's instructions
and/or regulations in force in the
country of use.
Never drink the descaling solution or any prod-
ucts dispensed until the cycle has been carried
out to the end. Never use vinegar as a descaling solu-
tion.

the brew unit (8) from the bottom and turn it from left to
