Use a soft and damp cloth for cleaning.
Never use abrasive or chloric detergents!
Empty the water drip tray regularly and do not wait until it is full.
7.2 Group cleaning and degreasing
A group cleaner (in powder or tablet form) is available at your specialised dealer. With this detergent, you can clean
and degrease the group very easily. The cleaning is carried out using the blind filter included in delivery. The group
cleaning with our tablets can be carried every week. The group cleaning powder is a bit more fat-dissolving and can
be used in intervals of two weeks or every week using only half of the sachet content.
Follow the instructions as noted below:
1 Heat up the machine.
2 Put the blind filter into the filter holder.
3 Put a cleaning tablet into the filter holder.
4 Place the filter holder in the housing of the group.
5 Operate the group lever. The blind filter fills with water.
6 Let the detergent react, moving the group lever into the middle position. (Do not move it into the lower
position.)
7 Move the lever into the lower position after approx. 1 minute. In this way, the fats and oils can be discharged by
the infusion cylinder.
8 Repeat points 5-7 several times, until only clear water will be discharged by the infusion cylinder.
9 Rinse the filter holder and the blind filter with fresh water. Then replace it.
10 Operate the group lever for approx. 1 minute. Then move it back into the lower position.
11 Remove the filter holder and repeat point 10. After this, the group is ready for use.
Caution!
Beware of hot spillings while cleaning the group.
7.3 Prophilactic descaling (for water tank machines)
A regular descaling of the machine is recommended to avoid strong calcification and expensive repairing. While
descaling, always take into account the hardness degree of the water. It is very important to use a sparing descaler
which does not affect the metal. At your specialised dealer, you can purchase a descaler (in powder or tablet form)
which is perfectly suited for your machine. Just fill the water tank with fresh water and dissolve the descaler in it.
Then proceed as follows:
1 Heat up the machine until the operative pressure has been reached.
2 Switch off the machine.
3 Empty the boiler, operating the hot water dispensing. Discharge the heat exchanger, operating the group lever.
Then close the hot water dispenser and finish coffee dispensing.
4 Dissolve the descaler in water according to the instructions for use (see above) and pour the solution into the
water tank.
5 Switch on the machine. Thus, the empty boiler will be filled automatically. Afterwards, operate the group lever
until liquid is discharged by the group. The heat exchanger will fill with the descaler solution.
6 Place the filter holder with the blind filter into the housing of the group and operate the group lever 3 times for
about 20 seconds. Move the lever into the lower position after every operation. Thus, the expansion valve will be
descaled.
7 After this process, let the descaler react for approx.
½ hour.
8 Release the remaining descaler solution by operating the group lever.
9 Switch off the machine and empty the boiler by operating the hot water dispenser. (It is recommended to
unscrew and remove the nozzle of the hot water dispenser so that no dirt can be accumulated inside the nozzle.)
10 Pour fresh water in the water tank.
11 Switch on the machine. The boiler refills automatically with fresh water.
12 Refill water in the water tank.
