I have opened up my Vibiemme Piccolo when the thermostat stopped working.
it looks as though there is a capillary thermostat for brewing and a cheap normally closed 150DegC thermostat for steam.
The cheap thermostat for steam seems to be the ONLY thing protecting the boiler from exploding when in steam mode.. I cannot see any mechanical safety valve.
With the 150degC thermostat bypassed, the boiler quickly rose to 8 bar pressure before I turned it off at the wall.
Does anyone know if there is safety valve?
Thanks.
