8.5 PRESSURE TRANSDUCERS
The E1 PRIMA is equipped with two pressure
transducers: one reads the pressure of the
water after the pump and one reads the
steam boiler pressure.
As explained in paragraph 8.1, they are con-
nected to the control unit:
The water pressure transducer on
CN14.
The steam boiler pressure transducer
on CN15.
NOTE
The cable of the steam boiler pressure
transducer has a red label to recognise
it.
If the pressure in the smartphone app
Victoria Arduino E1 is unshown or certain-
ly wrong, check the cabling or replace the
proper pressure transducer.
8.5.1 REMOVAL OF THE WATER
PRESSURE TRANSDUCER
The water pressure transducer is placed on
the back of the machine. To remove it, pro-
ceed as it follows:
Remove the cup holder surface, the side
panels and the rear panel, as described
in chapter 3.
Unplug the connector.
