Then the water ilter 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 reill 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.

gramme is run and should only be
replaced once the programme is
inished.
