Help,
anyone out there have any ideas why my combi boiler will not switch back on
after it has reached thermostat temperature.
I can manually fire it back up again but why doesn't it do it automatically?

I'm afraid there is not enough information to give a reasonable answer. Two
possibilities spring to mind, but you'll need to provide a lot more details
to work out what the specific problem is.

1. Wiring fault.
2. Boiler thermostat broken, so it is hitting the overheat shutoff stat,
which is reset by manually restarting the boiler.
