Problem Cause and remedy
There is no crema on
the coffee or espresso.
The coffee beans are no longer fresh. If roasted
coffee beans are stored open for too long, the
carbon dioxide gradually escapes from the coffee
beans. The crema is no longer formed during
dispensing.
Of course, you can still use the coffee beans.
The coffee tastes weak.
The coffee grounds in
the waste container are
sludgy and grainy.
Insufficient coffee beans are getting into the grinder
and less ground coffee is being brewed. If you have
used a dark roast, this type of coffee bean is often
more oily. These oils can cling to the inside of the
coffee bean container and hinder the flow of beans.
Make a coffee and observe whether the coffee
beans drop into the coffee bean container.
Clean the coffee bean container more often if you
are using a darker, more oily bean.
Try other types of coffee bean which are less oily.
