Status
When the appliance is switched on, the gearmotor repositions itself as follows:
- It stresses microswitch 1 (see the following chapter)
- The gearmotor changes the rotation direction and moves upwards again by approx. 1-2 mm
- The boiler begins to heat the water for approx. 45 sec. at full power in order to
reach the optimal temperature. The temperature will then remain constant.
1. The coffee grinder starts the grinding process (controlled by pulses generated by a sensor)
2. The gearmotor (coffee unit) moves to the dispensing position
3. Preliminary dispensing phase (short pump activity, short pause)
4. The product is dispensed (the pump operation time depends on the amount of product
dispensed)
5. The gearmotor moves to the idle position (the dregs are expelled automatically)
