Ideal isar 30 he help

[Steveanbarb]

Hi, can anybody help with this one. My ideal isar 30he is making sounds like the gas is igniting and back firing in the flue system. Its definitely the gas. Cant understand what is causing it.
The only thing I can think of is that the ignition is being delayed somehow, allowing the gas to build up in the flue.
Any help would be appreciated.

Oh, and changing the boiler is not an option at present.
Cheers

Could be the ceramic burner damaged

Do you have a fault code in the window?

New sparkplug most likely answer, but must be fitted by a pro, hope this helps.

whooping noise? blocked condense, and as libby mentioned, a serious safety issue with earth brackets. plus the burner seal screws have a brilliant knack for coming undone. really really needs annual safety checks.

like all boilers.
