2.9 Adjustment tips
Cream layer too low
Cream layer perfect
Cream layer missing or too light
-
The grind is too fine
- Bitter taste
- The preparation time is too
long
- Ground coffee dosing is high
- Coffee drips from the splitter
The coffee is ground too fine
or the dispensed coffee is
too much. The extraction is
too extreme due to too long a
contact time (too many bitter
substances).
Advice: Set the coffee grinder
to a coarser setting (adjustment
is counterclockwise). Also,
decrease the coffee dosing by
0.1 sec.
Note!
When setting the grinder to a
coarser setting, there is a risk
of excess measurement (coffee
volume/weight increases) as
a result of which the espresso
group can jam.
- The grind is correct
- Perfect coffee taste
- The preparation time is
correct
- The coffee measurement is
correct
- Coffee sprays full and parallel
The coffee is ground well. The
taste extraction is optimal. The
cream layer is firm and persists
for a long time.
Advice: Enjoy your coffee.
- The grind is too coarse
- Weak taste
- The preparation time is too
short
- Ground coffee dosing is too
low
- Coffee sprays bend outwards
The ground coffee is too
coarse and cannot reach a
good extraction. The coffee is
underextracted. There is little or
no cream layer.
Advice: Set the coffee grinder
to a finer setting (adjustment
is clockwise). Adjust the grind
setting in steps of a maximum
of 1/4 turns each time. Do
not measure the first 2 cups
of coffee. Only the 3rd cup of
coffee is made 100% with the
changed grinding fineness!
