potterton netaheat profile no ignition?

our old potterton boiler has not been used for around two years and was working well then but today there is no ignition gas and power are all ok. any ideas.

First there's a call for heat - then the fan runs - then the pressure switch makes - then the pilot flame lights - and last of all the boiler fires up.

You would do well to call in a specialist engineer. This is their busy season I think.

Good Luck..., January 2016
