Problem
PRO 400:
The green LED flashes (1 second
on - 1 second off)
JUMP:
The display permanently shows
the message "Pi".
The machine is switched on,
but the machine does not work.
The coffee extraction (pump)
starts for a few seconds, stops
and starts again.
JUMP:
The display shows a negative
countdown followed by three
dashes ("- - -").
If the machine is not to be used for a long period of time, it is recommended to:
.. clean the brew group (see instructions in chapter 7.2). Afterwards, please do not clamp the portafilter
back into the group.
.. empty the boiler. Switch the machine off (power switch in position "OFF") and open the hot water
dispenser. Due to the boiler pressure, the boiler water is now discharged by the hot water dispenser. Close
the hot water valve again after emptying the boiler. To restart the machine, see chapter "First use".
How to froth milk like a "barista"
•
If possible, use cold milk, so you have longer time to froth the milk. The fat content of the milk is not
relevant, the protein content is important. Even homogenized milk is suitable - if you prefer.
