Service programmes
At certain intervals, depending on how the
appliance is used, the display will show one
of the following texts instead of the coffee
selection:
Service -

P

P

Then the water filter should be changed
immediately or the appliance cleaned or
descaled using the corresponding pro-
gramme (described on the next pages).
Otherwise the appliance may be damaged.
The service programmes can also
be started manually in the settings
menu (see “Displaying settings”).
Do not drink the liquids. Never use vinegar,
vinegar-based products, citric acid or citric
acid-based products for descaling. For
cleaning and descaling only use the tablets
intended for such. They were specially
developed for this fully automatic espresso
machine, and replacements are available
from retailers or customer service (see
“Accessories”).
Never put descaling tablets or any other
descaling agents in the drawer for ground
coffee/cleaning tablets.
Never interrupt the service programme.
If one of the service programmes is
interrupted, e.g. by a power cut, proceed as
follows:
1. Rinse the water tank (14) and refill it with
fresh water up to the “max” mark.
2. Press
o
start/stop (10). The cleaning
programme will now run for about three
minutes.
Cleaning
The appliance is ready for use again.
Descaling
Important:
If there is a filter in
the water tank (14), it needs to be
removed before the service pro-
gramme is run and should only be
replaced once the programme is
finished.
If the prompt
Service - descale
is displayed,
press and hold down
k

seconds. The display shows:
