7.1 Programming coffee dose
The measured doses of coffee may be modified (using
volumetric control) and memorised as follows:
press button T3 (on the keypad for the brew group to be
programmed), hold it down for more than 5 seconds and
check that all the LED lights on the keypad are lit, apart
from the T3 buttons.
Press the key corresponding to the dose to be
programmed (key T1 for example) within 30 seconds
(programming time-out). The LED of the dose being
programmed keeps switched on and blinking. During this
stage and for the entire coffee dose programming time
duration, the solenoid valve and the pump are activated.
If no dose key is pressed
within 30 seconds, it will
automatically escape from
programming mode.
