Greetings
This is not a normal fault I see on here with this kind of boiler. So please forgive me if I am asking out of turn.
This is the problem.
Central heating goes on ok for 30 seconds and overheats due to ( i think ) no flow.
* Pump ok and running
* No safety lockout
* PCB fine
* Thermistors fine
* diverter assembly gets hot
* CH outlet stays cool
* flushed CH pipework, flow ok
* Direct hot water works fine
* Flow pressure switch actuating ok
I suspect diverter assembly, can anyone suggest otherwise.
Is the diverter ok to replace?
Kind regards
Antonia
