Loud hum on boiler shutdown.

[Dowding]

Hi guys. I'm at my wits end with my ideal logic heat 15. It works fine and then all of a sudden it sounds like it's going to erupt. I've attached a short video to show the noise. Any one got any idea what's wrong? Our plumber was stumped and has visited 3 times and still can't fix the issues. Cheers[video=youtube_share;8k3j0DLcvBo]https://youtu.be/8k3j0DLcvBo[/video]

Hi.
Have you had this boiler serviced?

Probably not in most cases.
I'm afraid you will need a local gas safe engineer to sort your problem, as it's not a diy fix.

As above, please call in a competent gsr.
