Coffee grinder
The coffee grinder is driven by a direct current motor (1) using a worm screw helicoidal wheel transmission
(2). The worm screw (2) drives a plastic gear wheel (3), which turns the lower grinder (4) and the increment
pin (5)
Coffee grinder blocked
When the coffee grinder is working, the software monitors the current consumption. If the current value is very
high, the machine concludes that the coffee grinder is blocked; instead, if the current value is in the middle,
the machine concludes that all is ok and it goes on to do the product.
Because the current consumption of grinder changes depending on the situations (motor new or old, cold or
hot, coffee blends, etc.), these current targets are not static, but dynamic.

“Water low” message (water reserve)
Function:
The water level is monitored by a capacitive sensor, located one third of the way up
the water tank wall.
If the electronics assembly detects, by means of the sensor, that the amount of
water in the tank has dropped below the above mentioned level, a water reserve
remains available for the dispensing process underway (this will cover 200 flow
meter pulses).
The product dispensing process will then come to an end.
If a dispensing cycle ends after the sensor has been triggered (in the reserve) then
the display “Water low” continues to be displayed during the following dispensing
cycle.
