Combi boiler - heating not working Discussion Thread
Hello
The heating side of my Ariston Combi A23 has stopped working since a new 3 way valve has been installed.
It's been a hugely reliable boiler up until now with regular servicing.
When the heating is turned on the boiler ignites and looks to start up but then a few seconds in, knocking sounds comes from the boiler and kind of makes it's way down to the pump (which appears to be working) and then all stops.
The pressure is good.
Wondering if it is air in the system where it shouldn't be.
Any advice please.
