Baxi Solo 3PF 60 Cuts out after 1 hour - 1 day

[Steve Whiting]

Help!, my boiler Baxi Solo 3PF is about 4 years old and now cuts out when it feels like it, the little orange lights on the boiler all stay lit up the fan continues to operate as does the pump but no flame at the boiler. I can then turn off either the electrics or turn down the rotary control on the boiler and everything restarts nicely and may continue to work for 1 day or 1 hour. Any help or guidance would be much appreciated. Steve

Come on guys somebody must have a few ideas, please!

ok

If fan is running but there is no sparking at electrode trying to light pilot,
then I would go air pressure switch

Cheers mate, I'll investigate and let you know what happens.

It was a cut rubber tube leading to the pressure switch, not obvious until taken off small slits on it probably from assembly causing the pressure switch to act up.
