Ideal Classic with no hot water or rads

[KoSullivan]

I have an Ideal Classic NF wall hung boiler, a Grundfos 15/50 Circulating Pump. Boiler is about 8 years old with no problems till now, last service about 14 months ago and it suddenly stopped heating the water yesterday. The boiler sounds like it is working OK but only the pilot light is working, the main burner does not engage. Any ideas?

Thanks in advance
Kevin

main burner light for heating?

Is there power going to the boiler (valve)?

Yes it is the main burner light for heating. There is power going to the timer switch but how do i check if power is going to the boiler (valve)? and where is the boiler valve?
