Explanation:
Two processes start when the main switch is activated:
Firstly, the gearmotor is initialised. The gears move to MS1 (lower limit switch), change rotating
direction, leave MS1 and move to the home position (about 2 mm after MS1).
Exception: Magic Roma – functions like Vienna.
The instantaneous water heater is then activated for about 1 min 30 sec., heating the water to operating
temperature, whereby heating takes place for about 60 sec. continuously and then is alternated for the rest
of the time.
After activating the start button:
1. The grinder starts operating (about 5.5 sec.).
2. The doser is activated twice.
3. The gears move to brewing position.
4. Depending on the type of machine, pre-brewing begins (brief pump activation).
5. Main brewing process (duration of pump activation depending on selected coffee quantity).
6. The gears move to home position.
Comments:
If the machine is disconnected from the main power supply during operation (power failure/side doors
opened), the gears will complete the function commenced but without brewing (if the interruption
occurs before brewing, the coffee will be dispensed dry).
If operation is interrupted by removal of the dregs drawer, the machine will continue its function
unrestricted once the drawer is returned.
