OPERATING INSTRUCTIONS
Check that the two red buttons have snapped out, otherwise the door can-
not be closed.
NOTE 1: If the infuser is not inserted correctly, until it clicks into
place, and the two red buttons have not snapped out, the service
door will not close and the machine will not operate (when switch-
ing on the machine the light starts flashing (section 12 - point
9).
NOTE 2: if it is hard to insert the infuser, (before inserting it)
squeeze it into size by pressing it vigorously from above and
below at the same time, as shown in Figure 32.
NOTE 3:
if it is still hard to insert the infuser, leave it out of the machine,
close the service door, unplug from the outlet then plug in again. Wait
for all the lights to go off, then open the door and replace the infuser.
• replace the drip tray, complete with the grounds container;
• close the service door.
10.3 DESCALING
Due to the continuous heating of the water used to make the coffee, over
time it is normal for the tubing inside the machine to fill with lime scale.
When the light starts flashing (section 12 - point 5), it is time to
descale the machine.
NOTE:
when the light switches on, the coffee maker can still be used to
prepare coffee.
Proceed as follows:
• Empty the tank and pour in the contents of one bottle (125 ml) of DUR-
GOL descaler plus one liter of water. For subsequent descaling opera-
tions, descaling solution can be purchased from authorized technical
service centers.
Note: Make sure splashes of descaler do not fall onto surfaces sensi-
tive to acid such as marble, limestone and granite.
• place a container with a minimum capacity of 34 oz. under the
cappuccino frother (Fig. 3);
• turn the machine on by pressing the button (Fig. 4).
• wait for the green and indicator lights to come on steady.
• press and hold the button for at least 5 seconds (Fig.14). The
decalcification warning light will illuminate (section 11 - point 8) to
indicated the start of the descaling program (the and lights
remain off to indicate that it is not possible to make coffee).
• turn the steam knob half a turn counter-clockwise (Fig.5). The
descaling solution will come out of the cappuccino frother and
start to fill the container underneath.
• the descaling program automatically performs a series of deliver-
ies and pauses, so as to remove the lime scale deposits from
inside the coffee maker.
