OPERATING INSTRUCTIONS
Check that the two red buttons have opened back out, otherwise the door
cannot close.
NOTE 1: If the infuser is not inserted correctly until hearing the
click and the two red buttons have not opened out properly, the
service door will not close and the machine will not operate (when
switching on the machine the light starts flashing (chap. 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 mains 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( chap. 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:
• prepare the solution as indicated on the packaging of the
descaling product supplied with the coffee maker (to purchase
this contact an authorised Dè Longhi service centre).
ONLY USE
THE DESCALING SOLUTION SUPPLIED BY DE’ LONGHI.
• Pour the contents of the bottle of descaler (0.5 litres) into the
water tank and then add water (0.5 litres, as described in the
instructions on the bottle).
• place a container with a minimum capacity of 1.5 litres under
the milk 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
light inside the button switches on (chap. 11 - point 8) to indicate
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 anticlockwise (Fig.5). The
descaling solution will come out of the milk frother and start to
fill the container underneath.
• the descaling program automatically performs a series of deli-
veries and pauses, so as to remove the lime scale deposits from
