Problem
Little or no crema on top of the
coffee
Sparse coffee dispensing, only drop
by drop
Weak "body"
Foam instead of crema
The machine is switched on, but the
machine does not work.
The machine does not stop working
and takes in air.
Filter holder/ brew group is
dripping.
If the machine will not be used for a long period of time, it is recommended to
.. clean the brew group (see instructions on page 29). Afterwards, please do not clamp the filter holder back into the
group.
.. empty the boiler. Switch the machine off (power switch in position "0") and open the hot water dispenser. Due to
the boiler pressure, the boiler water is now discharged by the hot water dispenser. Close the hot water handle
(MECHANIKA / TECHNIKA) or the hot water lever valve (MECHANIKA PROFI / TECHNIKA PROFI) again after
emptying the boiler. To restart the machine, see chapter "First use".
How to froth milk like a "barista"
•
If possible, use cold and fresh milk with a fat content of approx. 1.5 % or 3 %. Even homogenized milk is
suitable - if you prefer.
•
Use a frothing container (made of metal) with a minimum volume of 0.5 litres. The size of the container should
not be too wide. A narrow and high container is perfect.
•
Open the steam valve for approx. 5 seconds to release the condensation water and to create dry steam.

Increase the brewing-pressure.
Use approx. 7 g of coffee for every
cup.
Reduce the grind.

Make sure that the floater in the
water tank is in the correct position.
(The side of the floater with the
magnet point must face towards the

magnet point on the lower part of
the floater side.)
