Figure 21. Pry filter basket from filter holder with the group screen extractor.
Clean filter holder
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.
Described next is the back flush procedure for an individual group.
Procedure
1. Remove the filter holder, flush the group briefly (with flush-handle).
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
) and
replace it with a blind filter.
4. Scoop 1 teaspoon of coffee dissolving powder in the blind filter and lock the filter holder in the
group.
5. Pull the brew-lever into locking position, unlock when pressure no longer rises (appr. 3.5 bar):
pressure will quickly rise to appr. 9 bar.
6. Keep away from the reach of the brew-lever, then relief pressure (with handle); the brew-lever will
return to resting position very quickly, do not remove the filter holder.
7. Repeat steps 5 and 6 eight times (pressurise, then de-pressurise).
8. Remove the filter holder from the group, clean the blind filter by flushing it under the tap, flush the
group for approximately 5 seconds to remove possible powder from the group screen.
Now do it again without adding cleaning powder to remove all powder from the group:
