Hi All,
I have an intermittent fault with my boiler (S/N N024940705).
When the the boiler is asked to come on for an extended period of time, eg heating the house from cold, or running hot water for a long time, the burner goes off. It appears that the fan stays on. After about 30 seconds the middle light (of 3 LEDs) goes red, and the outer two lights remain flashing green.
If the heating is turned off for a few minutes, then put back on the boiler fires back up and may run fine for a while before doing the same fault.
I have followed the troubleshooting in the service manual and read several similar problem posts on here but not really any closer to understanding where the fault may lie.
Can anybody suggest any troubleshooting steps I could take before calling a local engineer.
Many thanks in advance.
