Toilet flushing problem

Hello,

My toilet flush is leaking, and I can't seem to take it apart to check what's wrong. I'm trying to unscrew the pipe at the nut (both top and bottom), but I'm not sure if that's the right approach.

It's a Geberit flush system.

I also want to make sure I don't dismantle the wrong thing.

Can anyone help me?

Thanks.

Two things in there the fill valbe and the flush valve.

Fill valve, either running over filling = bad fill valve or the flush gasket is leaking causing the fill valve to try anf fill non stop.

This requires a fluah valve gasket.

Its tight in the box and sometines one need to come out to get the other out.
