the pot. After removing the pot the drip-stop in the filter prevents coffee from
dripping.
Before brewing more coffee the appliance should be left to cool down for a few
minutes.
Cleaning
Disconnect the power plug and leave the appliance to cool down.
Never immerse the appliance in water; simply wipe the exterior using a damp
cloth with a drop of washing-up liquid.
Clean the filter under running water or in the dishwasher. Rinse out the interior
of the pot with nothing but warm water after every use. Never clean the pot in
the dishwasher. If deposits form inside the pot after it has been in use over a
longer period, the deposits can be removed gently with a denture cleaning tablet:
Fill in water, add the tablet, and leave to take effect for several hours. Then rinse
the pot several times.
Do not use harsh or abrasive cleaning agents.
Decalcifying
Limescale and calcium deposits result in a loss of energy and impair the service
life of the appliance. The appliance will switch off prematurely if the deposit is
too excessive. It is then very difficult to remove the deposit. We therefore recom-
mend you to decalcify the appliance regularly, but at the latest when the brewing
time increases significantly or there is more noise during the brewing process.
The following values are offered for guidance and are based on daily use in a
household.
Hardness range Hardness
1 soft 0 - 7° dH
2 medium >7- 14° dH
3 hard >14 - 21° dH
4 very hard >21° dH
1° dH corresponds to approximately 0.18 mmol/l Ca and Mg ions
You can obtain details of the water hardness range in your residential area from
your water works or community offices.
We recommend using durgol® universal. This decalcifier is highly effective,
protects the material and does not require any additional exposure time.
You can obtain this decalcifier where you bought the appliance or from select
dealers, or you can order it directly from wmf consumer electric.
Insert the paper filter and place the pot into the automatic coffee maker. Fill 1-2
cups of durgol® universal into the water reservoir, fill up the reservoir with tap
water to the 9 cups mark and switch on the appliance. During the decalcifying
process repeatidly switch off the machine for a few minutes. This will ensure an
optimal decalcifying effect.
Then let a reservoir full of tap water run through to rinse the appliance.
On no account use vinegar or vinegar essence, as the materials in the appliance
