Hi All,

Has anyone ever come across this clicking noise before (see video, starts around 16 secs in)? Just bought a new house with this fitted only 2 years ago.


Thanks

Does it always click or only on first warm up ?
 
i think it’s when there is “demand” - when it’s running “idle” it doesn’t do it as often. I do hear it happening a fair few times a day though, so it’s not just once.
 
Sounds like hex expanding due to heat mention it when you have it serviced might want the hex bolts slacking 1/2 a turn etc
