Smeg DWI614 – how do I remove air break chamber?

My Smeg DWI614 leaks at the O rings of the right hand side air break chamber, causing E1 error. I want to change the O rings but cannot see how to remove the chamber. It looks like it is held by the grey plastic ring on the inside of the washing compartment, but I cannot figure out how to remove it. Does it unscrew? Does it prise off? I am stuck on this one.

Any help appriciated.

OK a bit more Googling and it seems the part that holds the airbreak chamber (Also called IWMS – Inlet Water Management System) is called a load ring and it seems to have a thread on it (Looking at the photo). So… I think I’ll need the use of a strap wrench..

Keep you posted.
