Need to remove the lid on my Roca toilet cistern but cannot access the plastic screw under the twin flush buttons, one half moon 6Lt.flush button the other round button 3 Lt flush.
The halfmoon flush button clicks in place and holds the round button so it doesn't pop out on return after flushing. So the problem is removing the clicked in halfmoon button enabling the other to be lifted clear to access the securing screw....mistake should have left it out.
