  Important!   Before  descaling,  make  sure  the  water 

softener filter has been removed. 

 Important!   Descaler contains acids which may irri-

tate the skin and eyes. It is vital to respect the manufacturer’s 
safety warnings given on the descaler pack and the warnings 

relating to the procedure to follow in the event of contact with 
the skin and eyes. 

 N:B:: Use the descaler recommended by the manufac-

turer only.  Use of other descalers invalidates the guarantee. 
Failure to descale the appliance as described also invalidates the 
guarantee.

Over time, constant heating up of the water used to make the 
coffee leads to limescale building up in the inner circuits of the 
appliance. 
When “DESCALE” is displayed, the machine requires descaling.  
Proceed as follows:
•  press  the  MENU  button  (C2)  (the  light  over  the  button 

comes on) then press the NEXT (C3) button repeatedly until 
the appliance displays “DESCALE NO”;

•  press the CHANGE button (C4) and the appliance displays 

“DESCALE YES”

•  press the OK button (C5) to start the descale programme;
•  empty the water tank, pour the contents of the descaler 

bottle into the tank respecting the instructions given on 
the descaler pack, then add water.

 

When descaling subsequently, use descaler of the same 
type and brand as supplied (available from the manufac-
turer’s authorised Customer Services) or a descaler recom-
mended by Customer Services. Always follow the instruc-
tions on the pack. 

•  attach the hot water spout to the nozzle;
•  place a container with a minimum capacity of 2  litres / 

67.63 oz under the hot water spout (fig. 3);

•  press the OK button (C5). Descaler flows out of the hot wa-

ter spout into the container below. 

 

“APPLIANCE IN DESCALE” is displayed;

•  the descale programme automatically performs a series of 

deliveries and pauses to remove limescale deposits from 
inside the machine.

•  After about 30 minutes, the appliance displays “RINSING 

FILL TANK”.

The appliance must now be rinsed through to eliminate residues 
of descaling solution from inside the appliance. Proceed as fol-
lows:
•  Empty the water tank, rinse and fill with clean water.
•  Replace the tank;
•  Empty the full container and put back under the hot water 

spout;

•  Press the OK button (C5). Hot water flows out of the spout 

into the container below and the appliance displays “RINS-
ING”;

•  When the water tank is empty, the appliance displays the 

message “RINSING COMPLETE... PRESS OK”;
