The following messages will appear on the
display at certain intervals, either
“Descaling programme urgently required!”
or
“Cleaning programme urgently required!”
or
“Calc‘nClean programme urgently required!”
.
The unit should immediately be cleaned or
descaled using the appropriate programme.
Alternatively, the two processes Descale
and Clean can be carried out together using
the Calc‘nClean function (see the section
“Calc‘nClean”). Failure to carry out the
service programme according to the instruc
tions may damage the appliance.

Warning!
For each of the service programmes,
use descaling and cleaning agents
as described in the instructions and
observe the (relevant) safety infor
mation.
Never interrupt a service programme.
Do not drink liquids!
Never use vinegar, citric acid or any
vinegarbased or citric acidbased
agents. Never place descaling tablets
or other descaling materials in the
coffee drawer!

Important:
Before starting each service program
(Descale, Clean or Calc’nClean)
remove the brewing unit, clean as
instructed and replace it.
Be careful not to jam the milk tube
when closing the door.
After completion of each service
programme, wipe the appliance
immediately with a soft, damp cloth
to remove any residues from the
descaling and cleaning solution. It is
possible for corrosion to form under
neath such deposits.
New sponge cloths may contain
salts. Salts can cause rust film on
stainless steel and must therefore be
washed out thoroughly before use.
Clean the beverage outlet, milk tubes
and connecting piece thoroughly.
Specially developed, suitable
descaling and cleaning tablets are
available from retail outlets or from
customer services (see the section
“Accessories”).
