worchester 9.24 cutting out

[alanjames2406]

hi, my worchester 9.24 electronic is working fine when i use it for hot water, but when i turn on the central heating it runs for a short while approx 1 min then cuts out then restarts runs for another min cuts out again over and over again. i suspect a thermostat. but which one and where to look please. thanks

I would expect a flow blockage or diverter valve sticking.

But like all boiler faults needs some diagnosis at the boiler.
