17. CLEANING
17.1 Cleaning the machine
The following parts of the machine must be cleaned regularly:
- the internal circuit;
- coffee grounds container (A11);
- drip tray (A15) and condensate tray (A10);
- water tank (A17);
- coffee spouts (A19);
- frother (“15.2 Cleaning the frother after use”);
- pre-ground coffee funnel (A4);
- infuser (A8), accessible after opening the infuser door (A7);
- touch screen (B).
Important!
• Do not use solvents, abrasive detergents or alcohol to clean
the coffee machine. With De’Longhi superautomatic cof-
fee machines, you don’t need to use chemical products to
clean the machine.
• None of the components of the machine can be washed
in a dishwasher with the exception of the drip tray grille
(A14).
• Do not use metal objects to remove encrustations or coffee
deposits as they could scratch metal or plastic surfaces.
17.2 Cleaning the machine's internal circuit
If the machine is not used for more than 3/4 days, before using it
again, we strongly recommend switching it on and:
- performing 2/3 rinse cycles by pressing
(B15);
- delivering hot water for a few seconds (section “16. Deliv-
ering hot water”).
Please note:
After cleaning, it is normal to find water in the coffee ground
container (A11).
17.3 Cleaning the coffee grounds container
When the light (B2) flashes, the coffee grounds container
(A11) must be emptied and cleaned. The machine cannot be
used to make coffee until you have cleaned the grounds con-
tainer. Even if not full, the empty grounds container message
appears on the display 72 hours after the first coffee has been
prepared. For the 72 hours to be calculated correctly, the ma-
chine must never be turned off with the main switch (A6).
Important! Danger of burns
If you make a number of cappuccinos one after the other, the
metal cup tray (A12) becomes hot. Wait for it to cool down be-
fore touching it and handle it from the front only.
To clean (with the machine on):
• Remove the drip tray (A15) (fig. 21), empty and clean.
• Empty the grounds container (A11) and clean thoroughly
to remove all residues left on the bottom.
• Check the condensate tray (A10) (red) and empty if
necessary.
17.4 Cleaning the drip tray and condensate tray
Important!
The drip tray (A15) is fitted with a level indicator (A13) (red)
showing the level of water it contains (fig. 22). Before the in-
dicator protrudes from the cup tray (A12), the drip tray must
be emptied and cleaned otherwise the water may overflow the
edge and damage the machine, the surface it rests on or the
surrounding area.
To remove the drip tray:
1. Remove the drip tray and the coffee grounds container
(A11) (fig. 21);
2. Remove the cup tray (A12) and drip tray grille (A14), then
empty the drip tray and grounds container and wash all
components;
3. Check the red condensate tray (A10) and empty if
necessary;
4. Replace the drip tray complete with grille and grounds
container.
Important!
When removing the drip tray, the grounds container must be
emptied, even if it contains few grounds.
If this is not done, when you make the next coffees, the grounds
container may fill up more than expected and clog the machine.
17.5 Cleaning the inside of the coffee machine
Danger of electric shock!
Before cleaning internal parts, the machine must be turned off
(see section “5. Turning the machine off”) and unplugged from
the mains power supply. Never immerse the coffee machine in
water.
1. Check regularly (about once a month) that the inside of the
machine (accessible after removing the drip tray (A15))
is not dirty. If necessary, remove coffee deposits with the
brush (C5) and a sponge;
2. Remove all the residues with a vacuum cleaner (fig. 23).
17.6 Cleaning the water tank
1. Clean the water tank (A17) regularly (about once a month)
and whenever you replace the water softener filter (C4)
