So, I had an old and disgusting Geberit dual flush that didn't work very well, so I decided to replace it. Cistern is 110.830.00.1, so got a compatible Geberit TwinLine 240.515.00.2.
I then installed that but when you press the stick to activate the flush, it starts flushing but then doesn't stop because the central canister doesn't fall.
I then took the swinging-arm mechanism out and it falls perfectly fine, so it isn't the canister.
I put the swinging-arm mechanism back in and it doesn't fall again.
Interestingly, I have established that when the swinging-arm is raised, it not only pulls the canister up but also pushes it backwards ever so slightly. I think this is then causing it to then rub against the holder in the bottom of the cistern, the friction from which is thereby preventing it from falling.
So my question I suppose is: how do you get0 the arm to only raise the canister and not oush it backwards?!
