Hello, had this bolier for a month now. LAst friday we had the above error message (and no heating) so reset the boiler - all was fine.
But it happened again today. Thats twice in 5 days. Doies anyone know what could be causing it?
Also everynow and then, when the boiler starts up ,the whole thing "pops" quite violently. Again any ideas please? Thanks
