Hello everyone, this is my first post in this amazing forum.
I have recently bought an old Rancilio Nancy (probably from the 90's). The machine seem to work fine, but nonetheless I have not been able to get 1 decent shot out of it.
My grinder is a Rancilio Rocky that matches the colours of the Nancy (was bought together with the machine), and seems to be grinding ok.
Here is the pump:
Here is the Boiler - Watlow - OPV:
And here is the detailer view of the OPV:
And here the thermostats:
Ok, so what I would love is if someone that knows this machine could help calibrating the thermostat and the brew pressure (through the OPV). But, to tell the truth I don't know exactly how to do it. The water seems to be coming out too hot because too much water vapor comes out of the shower when I turn on the switch. And the pressure seems to be too high (but I don't know how to verify it because I don't know what pump it is to check the flow in 30 seconds). Well, any help at all will be treasured.
