Switching on
When the machine is switched on, the gear motor repositions itself as follows:
- It acts on microswitch 1 (see following. section)
- The gear motor changes its rotation direction and moves upwards again by approx. 1-2 mm
- The boiler begins to heat water for approx. 45 seconds. It absorbs all the available heating power
in order to reach the optimal temperature. The temperature will then remain at a constant level.
Coffee cycle
1. The coffee grinder starts the grinding process (controlled by pulses generated by a sensor)
2. The gear motor (brewing unit) moves to the dispensing position
3. Preliminary dispensing phase (short pump activity, short pause)
4. Product dispensing (the pump operation period is defined by the amount of product dispensed)
5. The gear motor moves to its home position (the dregs are expelled automatically)
