    Technical questions Faema E91 Diplomat 3group

    I have Faema E91 Diplomat (Group 3)
    It has an error code: boiler overpressure E1
    Everything works but the heating does not turn on.
    There is no pressure on the boiler, even if the machine so claims.


    I was thinking of changing the temperature sensor.
    How is the calibration performed?
    What kind of values is the temperature sensor? (if it works)
    Would I need "electronic service key"?
    What should be done?


    I am from Finland... tell me also if the message is somehow unclear
