Figure 16. Pry filter basket from filter holder with the group screen extractor.
Clean filter holder
Remove the filter basket from the filter holder and clean the filter basket with a little washing up liquid
and plastic scouring pad or firm brush. Soak the metal part of the filter holder for 10 minutes in a
solution of 1 tablespoon of coffee dissolving powder in 0.5 litre hot water. The plastic handle will
eventually disintegrate in this solution and should thus be kept out of the solution.
Caution!
Never clean the filter holder in a dish washer as dish washer detergent will ruin it.
Back flush group
Back flushing cleans the group and conduits from coffee residue which influences the taste of the
extraction since fresh (hot) water is transported to the coffee bed through these parts. It is advised to
back flush the groups at least once a day and more often when the machine is intensively used.
Note!
The automatic cleaning program
(button “clean program” in menu-window) is best performed at the
end of the day and is very useful as there is no need to repeatedly engage-disengage each group
individually. You should run the clean program twice: first with cleaning powder, then rinse the blind
filter baskets and run the program again without cleaning powder. In this second run you quickly
empty a blind filter in between pressurising of the groups, when the groups have depressurised you do
the same with the next group, etc.
Described next is the back flush procedure for an individual group.
Materials needed
•
Plastic group brush (included in shipment)
•
Blind filter (looks like a filter basket but has no holes, included in shipment)
•
Coffee dissolving powder (included in shipment)
•
Group screen extractor (included in shipment, or back end of teaspoon)
Procedure
1. Remove the filter holder, activate the group: shortly press the upper button (
Touchpad
) or group
handle (
Bastone
) and flush the group for approximately 5 seconds. Then shortly press again to
de-activate the group and stop the flow.
2. Clean the group screen and group seal with the plastic group brush.
3. Pry the filter basket (e.g. with the group screen extractor) from the filter holder (see Figure 16) and
replace it with the blind filter.
