Step 32:

Continue rinsing the system by

recirculation system!

Step 34:

Remove the collecting vessel.

Trouble shooting

•  The right coarseness of the coffee/espresso bean is important. If the coarseness is finer, more flavour will be 

extracted. If the setting is too fine, the contact time of hot water will be too long and too many bittern will be 
extracted. And also the crema clears away again. 

•  Varying the compacting pressure of the powder in the portafilter shows similar effects as varying the coarseness.

Taste is not okay?

Finding 

Possible cause 

bitter taste

beans ground too fine, beans compressed too much, percolation is too long, too 
much powder, too much pressure.

sour taste

no suitable water, water is too soft, brewing temperature is too low, beans 
ground too coarse, roasting is too light, percolation is too short, wrong coffee 
type (coffee roasting instead of espresso roasting).

off-flavour

bad bean quality, beans are stored too long, chlorinated water, wrong espresso 
type.

not enough flavour

not enough powder, coffee is too old, powder is too coarse, powder is not 
compressed enough, too much water.

Step 30:

Stop the supply. 
Turn the rotary knob to the top.
NOTE: The appliance carries excess 
water back into the water tank via a 
recirculation system!

Step 31:

Place a vessel below the outlet of 
the hot water/steam nozzle.

Step 29:

For rinsing the system, turn the 
rotary knob to the left. Dispense 2/3 
of the water.
Check the collecting vessel regularly, 
empty it if necessary.
