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).
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 (pulse-controlled).
2.
The gears move to brewing position.
3.
Pre-brewing begins (brief pump activation).
4.
Main brewing process (duration of pump activation depending on selected coffee quantity).
5.
The gears move to home position (dregs discarded).
