2.4.2 Coffee Waste (puck)
• It is very important how the compressed puck looks
like when it is thrown out of the brewer.
A too wet puck falling apart is a sign too little coffee
is being dispensed and / or the coffee grind is too
coarse tuned!
• Catch the puck while adjusting the compressed
puck. Tip; use the stainless steel brewer cover.
• A good puck is whole, dry and at least 15-17mm
thick.
• It is normal that a small amount of water leaves the
brewer when it opens.
2.4.3 Coffee grinder
There are two factors that affect the output of the
coffee grinder. The grinder rotation time (
2.1 Quick
recipe pro / Coffee)
and the
grinding fineness
of the
coffee grinder. Try to find a balance between:
• Cup volume
(menu setting)
• Amount ground coffee
(menu setting)
• Ground coffee coarse or fine (grinder adjustment)
• When the coffee grinder is set coarser, the volume of
the grind increases.
• When the coffee grinder is set finer, the volume of
the grind decreases.
• Only adjust the grinder finer when the grinder is
running! Adjustment from fine to coarse can be done
when the grinder is stationary.
• Only adjust the grind setting in steps of 1/4 turn.
Note: only the 3rd cup of coffee is 100% made
with the changed grind fineness! (do not measure
the first 2 cups).
Run in period grinding discs
Tests have shown that new ceramic grinding discs have
a run in period of 10 kg of coffee beans (about 1350
cups at 7.5 g / XL=1000 cup at 9.5 g.).
We recommend to re-adjust (finer) the grinder
after this period.
