1Main switch
Turn on the switch (led on) the machine is turned (apart from the boiler) and the pump is turned on to fill the boiler;
2Boiler resistance switch
On activating the switch (the led comes on) and power is supplied to the resistance for the boiler water.
3Cup heating resistance switch
By turning on the switch (led on), the cup heating resistance is power supplied.
4A Coffee dispensing switch (Mod.S)
With switch ON, coffee is dispensed;
With switch OFF, dispensing of coffee is interrup- ted.

-Start in continuous mode
-Initialize dose programming for
Each time a coffee is dispensed, the LED of the relative button lights up.
During dose programming, the LED of the 5th button flashes rapidly.
If the dose is supplied irregularly or the volumetric counter is malfunctioning, the LED of the pressed button flashes dispensing the dose on a time ba- sis.
5A Hot water button (picking up directly from the boiler) with two positions (Mod.S):
With switch ON, the LED flashes and hot water is dispensed directly from the boiler.
With switch OFF, the LED switches off and dispen- sing stops.
5B Hot water button (Mod.DE)
When the button is pressed, hot water is dispensed directly from the boiler for the set time or until the button is pressed again.
If you press the button for 2 seconds, dispensing is continuous and only stops when the button is pressed again.
