water back into the water tank via a
recirculation system!

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.
