why does my ferroli domicompact f30 only work in test mode?
In normal mode I keep getting F37 fault message ( low system pressure) although bar pressure is showing 2 bars, overnight the fault code changes to F3 (saftey thermostat tripped). I have bleed the radiators several times as the fault finder manual says the common denominator is air in system? but this has no effect!!! Can anyone help.
