What baxi is it? 133 isn’t a frozen condensate that’s a failure to ignite, do you have gas? Is the stop cock under it turned off?
Sounds like you’re having a couple of issues and the pressure and the failure to ignite are different issues. If it was pressure related it would be 119 if it’s a duotec
Thanks folks - I’m calming down and I’ve found my long johns.
Thanks @Airhead I had no idea it was potentially a consumable part, that’s really interesting.
