Sime super 90 internal fuse blown

[Robven]

Can anyone help, For some time their has been a noise like solenoid chatter when the heating is first turned on. Yesterday no heating when got up, made various checks and found an internal 1.6 fuse had blown. I replaced that and it fired up, with the chatter noise coming from the 24v input on the gas valve. If I remove one of the wires the noise stops but boiler flame is only on low heat. When system is hot, wire can be re-connected and boiler works properly. Is this likely to be the board, the gas valve, or a stat?

I think that you should be engaging a gas registered engineer to diagnose and repair your boiler.

We don't advise on DIY repairs here associated with gas/combustion.

I am, though I'm generally an installer. This is my partners boiler and she doesn't really want a new one at this time of year. Was going to join gas registered forum but it said this is done manually and may take a few days. I would like to get the bottom of the fault asap.
