Loud banging from Worcester Bosch Greenstar 24i Junior

[M.Joshi]

Hello All,

We have a small Worcester Bosch Junior 24i boiler which is making a loud banging noise when operating.

If a radiator valve or TRV is adjusted (turned), the noise disappears.

Is this likely to be a faulty radiator valve, TRV or something else?

The boiler has 3 radiators attached to it (2 normal, 1 towel). The towel radiator does not have a TRV fitted.

Thanks.

This is what I hate - cocky plumbers! I have no quarms about helping people on forums even though I am not in the trade. It is people like SGI that put you off believing there are genuine and honest people in the trade.

I have never heard of 'parameters of fun' and a 'flux switch' before. Could somebody please clarify?

fun creates negative pressure , and if there is restrictions in the burner the pressure will get lower therefore boiler needs a good clean ,
ist the forum good , you can write and then delete your post

Yes quite - you can choose to be more polite.

Is 'fun' short for something?

"fun"-fan ( spelling issue )

Oh, I see! However, mbar is generally associated with gas pressures not fan rotation?

What about 'flux switch'?

M joshi SGI gave you a price and you didn't take it you got another company in for less money and you still have problems
Do you really expect him to now tell you the problem for free????
Don't see any comment as cocky apart from yours this is a gas boiler that legally you can not work on so why should you be told what the problem may be I'm sorry you didn't get a decent plumber in on the first place but if you want it sorted once and for all I'd do a bit of apologising to SGI

mbar = 'millibar' just a unit of measure is used for lots of things including in the weather forecasts

I thought I hired what was a good Gas Safe Registered company to do the service - turns out that they didn't do the service correctly. When I saw 'fun parameters' and 'flux switch' mentioned, I assumed these were absurd comments. If I am wrong, please correct me.

I don't intend to repair the fault myself and wouldn't touch any gas parts. Besides, I've heard that the hydraulic block is a nightmare to remove on this model anyway.

I am not asking anyone to repair the boiler for free. Just after some genuine advice so that I'm not fobbed off. I have provided advice to other users on this forum without any sly remarks and expect the same from other members regardless of their experience level or number of posts.
