6 Press the star key and wait until liquid is released from the group. Thus, the heat exchanger is filled with descaler
liquid. Press the star key again.
7 Clamp the filter holder with the blind filter into the group and press the star key. Dispense liquid for approx. 20
seconds and press star key again to stop dispensing. Thus, the expansion valve is descaled. Repeat this process 3
times.
After this procedure let the descaler work for approx. ½ hour.

9 Make the descaling liquid circulate through the group by pressing the star key.
10 Switch off the machine and empty the boiler by dispensing hot water. Then close hot water valve again.
It is recommended to unscrew and remove the nozzle of the hot water dispenser so that no dirt
can be accumulated inside the nozzle.
11 Rinse the water tank and remove lime or descaler residues.
12 Fill fresh water into the water tank.
13 Switch on the machine. Thus, the boiler is automatically filled with fresh water.
14 Refill water into the water tank.
15 Start the cleaning mode with the blind filter to remove descaler residues from the expansion valve. Then remove
blind filter from the filter holder.
16 Press star key for approx. 60 seconds to rinse the heat exchanger.
17 Repeat point 9 to 11 three to five times to rinse the boiler.
Important!
These descaling instructions are only meant for prophylactic descaling. Please do not descale the
machine if it is already calcified. While descaling the machine, the lime residues can plug several
components, like valves, gauges etc., causing damage to your espresso coffee machine. In this case,
please contact your specialised dealer. It is probable that a professional descaling has to be carried out
which requires the disassembling of boiler and tubing.
Damage to persons or to the material, caused by calcification in and at your machine, is not subject to
the producer's liability.
In this case, also the warranty expires. Machines will be only accepted for repair after foregoing
technical advice and written acknowledgement.
Please do not enclose loose parts e. g. filter holder or drip tray when sending in the machine for
repairs / maintenance.
