Certain models are fitted with a water softener filter. If this 
is not the case with your model, you are recommended to 
purchase one from De’Longhi Customer Experience.  
To use the filter correctly, 
follow the instructions 
below. 

Installing the filter
1.   Remove the filter from 

the packaging.

2.   Turn the date indicator 

disk (see fig. 33) until 
the next 2 months of 
use are displayed. 

The filter lasts about two 
months if the appliance is 
used normally. If the coffee 
maker is left unused with the 
filter installed, it will last a 
maximum of three weeks.

3.   Remove the tank from 

the appliance and fill 
with water. 

4.   Insert the filter in the 

water tank and immerse 
it completely for ten or 
so seconds, sloping it to 
enable the air bubbles 
to escape (fig. 34). 

5.   Insert the filter in the 

filter housing (fig. 35A) 
and press as far as it will 
go. 

6. 

  Close the tank with 

the lid (fig. 35B), then 
replace the tank in the 
machine. 

When you install the filter, you must notify the appliance of its 
presence.

water, fill with clean water and replace. 

 

“Rinsing... Confirm?” is displayed.

and replace it empty under the hot water spout.

9.  Press the  

button to start rinsing. 

 

Hot water flows out of the spout and the message 
“Rinsing...” is displayed. 

10.  When the water tank is completely empty, “ Rinsing 

Complete Confirm?” is displayed. 

11. Press 

the 

 button. 

12.  Insert the filter (if present) in the tank (see section 

“Installing the filter” on page 18), fill the water tank again 
and the appliance is ready for use. 

The DESCALE message is displayed after a period of time 
according to water hardness.  
The machine is factory set for a hardness value of 4. 
The machine can also be programmed according to the 
hardness of the mains water in the various regions so that the 
machine needs to be descaled less often. 

Measuring water hardness
1.  Remove the “total hardness test” indicator paper attached 

to this manual from its pack. 

2.   Immerse the paper completely in a glass of water for one 

second. 

3.   Remove the paper from the water and shake lightly.  
 

After about a minute, 1, 2, 3, or 4 red squares form, 
depending on the hardness of the water. each square 
corresponds to one level.
