DESCALING
Limescale normally builds up with the use
of the appliance.
The machine must be descaled when the
icon appears on the display.
Steady on
Important Note: It is recom-
mended to refer to the next
section, "Remarks on Descaling", for
some tips about keeping the machine
in perfect working order.
Do not switch off the ma-
chine during the descaling
procedure.
Only use the GAGGIA descal-
ing solution. Its formula has
been designed to ensure better ma-
chine performance and operation for
its whole operating life. If correctly
used, it also avoids alterations in the
brewed product.
Warning! Never drink the des-
caling solution or any prod-
ucts dispensed until the cycle has
been carried out to the end. Never use
vinegar as a descaling solution.
Before descaling, remove the Pannarello
(if supplied) from the steam wand as
described in the "Cleaning and Mainte-
nance" section.
• Turn the machine on by pressing the
ON/OFF button. Wait for the machine
to finish its rinse and warm-up
process.
