Clean steam wand
Milk easily bakes to the hot inner and outer surfaces of the steam wand and tip. Therefore, the steam
wand and tip should be cleaned with a damp cloth directly after each use. Do not use this cloth for
anything else than the steam wand.
Note!
Immediately after steaming milk you should purge the steam wand with a little steam. This will
prohibit milk creeping into the pipe, and even into the valve house, through so called capillary rise.
Flushing also prevents clogging of the 4 holes in the tip. In the event that clogging occurs, place the
end of the steam wand and tip for several minutes in a glass of hot water. The remains will soften and
can be wiped off easily. NEVER scrape, grind or cut the steam wand or tip since it leads to damage.
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 when the machine is intensively used several times per
day.
Note!
The automatic cleaning program 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 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 procedure for an individual group in which the other group(s) remain(s)
operational.
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 filter holder and flush the group for approximately 5 seconds.
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 15) and
replace it with the blind filter.
4. Scoop 1 teaspoon of coffee dissolving powder in the blind filter and lock the filter holder in the
group.
5. Activate the group until full 9 Bar pressure is reached, then de-activate the group.
6. Wait for approximately 3 seconds then activate the group again for approximately 5 seconds.
7. Repeat steps 5 and 6 eight times (wait 3 seconds, activate group 5 seconds), or use the automatic
back-flush program (see page 9 or 11).
8. Remove the filter holder from the group, clean the blind filter by flushing it under the tap, activate
the group for approximately 5 seconds to remove possible powder from the group screen.
9. Lock filter holder in group, activate pump for about 5 seconds, de-activate pump, remove filter
holder and pour out remaining liquids.
10. Repeat step 9 four times (or use the automatic back-flush program).
11. Pry the blind filter from the filter holder and replace the filter basket.
Warning!
Finishing the back flush routine without cleaning powder is essential to prevent remnants
of cleaning powder settling between the plunger and housing of the 3-way group valve.
