Hi,
My Myson Apollo 30B boiler now longer works. There's no pilot light. While holding in the gas button I don't hear a hiss like my dodgy memory suggests I did last time I lit the pilot light some years ago. Pressing the spark button doesn't visibly do anything and no pilot flame ever appears.
I've a call out to an engineer, but am I right in thinking that the thermocouple is only concerned with keeping gas flowing once the pilot's lit so it wouldn't be relevant here? Any typical faults, e.g. gas pipe blocked, that may cause these symptoms.
Thanks,
Sam.
