5.3
Idling current grinder
For a correct “empty” report the grinder idling current
must be entered into the system as base following the
entering of the factory values or motor replacement. This is
done via a service routine.
Note for technicians
The idling current must by all means be determined with
the grinder completely empty.
5.4
Portioner calibration
The calibration must be done so that the amount of coffee
powder can be correctly set in grams in the settings menu.
Empty message will be also affected, however after
calibration the grinder correction is reset to 100%.
5.5
Filling the boiler
At the first setup of a machine delivered by the factory
the first filling is done automatically as part of the setup
routine.
The boiler is filled for 300 seconds. It makes no difference
if it has already been filled or not. Excess water is
discharged into the drip tray via the expansion tube.
During normal operation an empty boiler does not
automatically fill itself when the steam boiler electrode is
touched. In machines without steam boiler filling is always
run for 300 seconds during first putting into operation.
5.6
Filling the steam boiler
At the first setup of a machine delivered by the factory
the first filling is done automatically as part of the setup
routine.
The steam boiler is filled via the supply valve until the
electrode reports “contact”. The air escapes via the
steam dispensing or cappuccino valve (according to
specifications) as filling an empty boiler up to the electrode
is impossible against the air cushion.
Without de-aerating via this routine (e.g. following
replacement) a boiler cannot be filled against an air
cushion inside.
