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
