Replacing Geberit dual flush button

Hi folks

I'm trying to replace a broken Geberit flush button (for a Laufen Pro toilet) and have bought what I believe is an exact replacement. It's a dual flush: one section of the button pushes down a central plastic rod and the other pushes down a sleeve around it. The trouble is that the central rod from the old button seems to be firmly stuck in the flush valve and hasn't come away with the rest of the button, as shown in the photos (old button on right, replacement on left). I don't want to force it for fear of breaking the valve.

Any thoughts on how to unstick this – or do I simply need to replace the whole valve?

Many thanks

Remove the whole dump valve to examine more closely and clean it up/lubricate it. It is all snap together plastic so you should be able to dimsantle and reassemble with ease.

Identify the exact dump valve and speak to geberit technical if it isn't immediately obvious to you once it's out of the cistern.
There "may" be some tabs to push but usually its just a small turn anticlock and the valve will then lift off its cradle.
Great, many thanks. Will take it out this evening to have a closer look.
