13.4 Cleaning the boiler outlet
About every 300 coffees, the espresso boiler outlet must be
cleaned as follows:
• Make sure the appliance is not hot and that it is unplugged
from the mains;
• Using a screwdriver, unscrew the screw fixing the espresso
boiler outlet (fig. 27);
• Remove the boiler outlet;
• Clean the boiler with a damp cloth (fig. 28);
• Clean the outlet thoroughly in hot water using a brush.
Make sure the holes are not blocked. If necessary, clean
with a pin.
• Rinse under running water, rubbing all the time.
• Replace the boiler outlet, making sure it is correctly posi-
tioned on its gasket.
Failure to clean as described above invalidates the guarantee.
14. DESCALING
We recommend descaling the coffee maker about every 200
coffees. We recommend using commercially available De’Longhi
descaler (C6). Proceed as follows:
1. Fill the tank with the descaler solution, obtained by dilut-
ing the descaler with water following the instructions on
the pack;
2. Press the
button;
3. Make sure the filter holder is not attached and position a
container under the boiler outlet and cappuccino maker;
4. Wait until the
OK
light comes on ;
5. Press the
button and deliver about 1/4 of the solu-
tion in the tank. At intervals, turn the steam dial to deliver
water from the cappuccino maker. Then interrupt water
delivery by pressing the
button and leave the
solution to work for about 5 minutes;
6. Repeat point 5 another 3 times, until the tank is empty;
7. To eliminate residues of descaler solution, rinse the tank
well and fill it with clean water (without descaler);
8. Press the
button and deliver water until the tank
is empty. At intervals, turn the steam dial to deliver water
from the cappuccino maker;
9. Repeat points 7 and 8.
