Frequently asked questions
The brew unit or waste unit could not be pulled from the machine.
– The brew unit is not in the basic
position.
– The door was opened during
grinding or brewing.
No crema has formed or it is "different".
– Check if the grind control is set too
coarse or too fine.
– Check what temperature range the
coffee type is set. If the
temperature is too high, there are
black areas in the crema.
Too much crema has formed and is above the coffee dispensers.
Some coffee types produce too
much crema when the coffee /
espresso temperature is set to the
maximum and the amount of ground
coffee is too much.
The milk froth does not flow but "spits".
Before using for the first time the water lines need to be filled. See "Making
coffee - Cappuccino and milk froth".
When preparing milk froth for the first time, the milk is spit from the mug.
The door was opened during the
heating phase. High steam pressure
has built making the steam
dispensed too strong when the valve
is opened.
When preparing milk froth the preparation starts, stops then starts again.
This is not a fault. The start and stop action aids the machine in preparing the
best froth possible.
You hear water gurgle or rushing.
The water tank has automatically filled.
