I have a Roca toilet that is filling constantly which is causing lots of condensation but it has a push button flush action & I don't know to remove that to get the lid off to check the ball?
we have one that has been doing the same take lid of and take the syphon out take washers off bottom and give them a clean they get dirty which i think lets water into the pan

Gently prise out the two buttons on the top. This will reveal a posi screw which you can then undo and remove the cistern lid.
