The dispensed coffee is
warm
The dispensed coffee is warm even if the
measured pressure is normal between 1
and 1.2 bar. In this case the pressure
reading is false.
Call a specialized technician
to check the pressure-release valve.
In the meantime, in order to be able
to use the machine, open the steam
valve; the boiler pressure will go
down to zero, which will power on the
heating element and cause the
temperature to rise. Perform this
operation daily when turning on the
machine.

In case 1 call a specialized
technician.
In cases 2-3 remove anything
covering machine or adjust machine
to a position for maximums
ventilation.
