The pilot light on our Potterton Netaheat 10-16 MkIIF went out overnight for no obvious reason. I cannot see how pilot light is switched back on. It has worked fine through the cold weather of late. Is there anything obvious that a layperson can do before calling in a gas safe engineer, who will probably want to sell me a new boiler!!

I had to replace the pilot flame sensor on mine and that worked a treat. It was only a few quid

The Netaheat does not have a pilot light, Please dont attempt to repair this boiler as is a positive pressure boiler and if you get the case on incorrectly fumes will leak from the boiler.
Chances are the gas valve has packed up but you should seriously consider a new boiler
