6 Switch off the machine, remove and clean the water tank and fill it with fresh water.
7 Switch on the machine and release approx. 1,000 ml of water from the group and the steam/ hot water valve (switch
pump/ hot water).
8 Repeat this process approx. 4 times to make sure that no descaler is left in the boiler.
9 Operate the group lever 3 times for approx. 20 seconds. Move the lever into the lower position after every operation.
Thus, the expansion valve will be descaled.
Then remove the blind filter from the filter holder.
Important!
These descaling instructions are only meant for prophylactic descaling. Please do not descale the machine
if it is already calcified only by the service-shop. 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.
