Descaling

Your appliance has an automatic descaling
programme. When the N icon lights up,
run the descaling programme as soon as
possible. If the descaling programme is not
run as instructed, the appliance may be
damaged.
Tip: With very hard, calciferous water,
please descale the appliance more often
than the N symbol is displayed. Even
iltered water contains low amounts of cal-
cium carbonate. Press and hold the start/
stop button for 10 seconds. N lights up.
Now proceed as described under "Running
the descaling programme".
Suitable descaling agents are available
from Bosch Customer Service (Article
No. 310967) or from specialty retailers.
Notes:
Never interrupt the descaling programme.
Never drink any of the liquids used in
descaling.
Never use vinegar or vinegar-based
products.
Always remove the ilter holder and the
ilter cartridge before starting the descaling
programme.
Running the descaling programme
► Remove the water tank, pour out any
remaining water, and reinsert it.
► Prepare the descaling solution accord-
ing to the manufacturer's instructions
and pour it into the water tank up to the
calc mark. A descaling agent approved

► Place a container holding at least
500 ml under the water outlet.
► Press and hold the temp. set button for
at least 3 seconds to start the descaling
programme.

small amount of solution is always left in
the tank.

temperature icon lights up, the descal-
ing program has inished.
► Rinse the water tank thoroughly and ill
up to the max mark with fresh water.
► Now select and draw warm water three
times to rinse out the appliance. Do not
drink this water!
The appliance is now fully operational
again, and you can re-insert the ilter
holder with the BRITA MAXTRA ilter
cartridge.
