I have a Baxi Solo Bolier.
When i call for hot water the boiler fires up for around 3 minutes (noises from the boiler get louder during this 3 minutes)then the overheat switch goes and i have to leave it a good 5 minutes before it will reset.
When i call for central heating the boiler does not fire up at all. So i dont know whats wrong with that.
I have had all the electrics checked and they are fine, the pump is also new aswell. Could it be the diverter? Valves ?
Im really lost now |

Sounds like lack of circulation. I would firstly check there is 230V at the pump when the hot water is on. The boiler pcb supply's this so if there isn't it could be a pcb failure.
The not coming on on heating sounds like a zone valve fault. If you have 2 zone valves then check for 230V at the orange wire from the heating valve. If a 3 port valve then do the same.
