the boiler fires up for around 10 seconds then cuts out?
had a call to change the prv valve as the boiler was losing pressure, reset the boiler sfter repressurising and the boiler fires for around 10seconds then cuts out. was thinking to pressurise the expansion vessel, or would it be the gas valve?
boiler make?
boiler model?
fault indicator lights flashing?
in what sequence?
does problem affect DHW or CH or BOTH?
my crystal ball is playing up so i cant tell what boiler you have
so i have to resort to using old fashioned methods of asking for as much relevant information as possible
