Toilet flush broken or just loose?

Hi there,

Question on a push button flush.

The button for flushing the toilet has come loose and wont tighten even when I screw it in. some pics attached. The toilet is built into the wall and is not a standalone "outside" type unit.

The mechanism which connects the push button to the flush has come off from the wall.

The problem seems to be that when someone pushes the button, it presses the flushing mechanism (on the other side of the wall) backwards, which doesnt generate enough force to flush the toilet.

My thinking is to just superglue this mechanism back onto the plasterboard, so it does not come loose when flush button is pushed.

Also I'm worried the screw looks damaged, which is why it doesn't stay when I screw the push button into the mechnism. any help appreciated.

Looks to me like there is a backnut missing the plastic unit does not screw on you push or pull the blue tab to clip it onto the button shaft/thread.
Super glue will not work try to ID the flush unit and get a replacement push button or even a whole unit and cannibalise it.
Lunns are a good source.

It may be the case the panel is too thick so you may have a bit of bodging to do if that is the case.
The button's threaded end section has snapped, it clips into the cabled plastic box section. If you push in the blue lever on the piece with the yellow cable going into it, you'll be able to pull out the slotted threaded end that has the white plastic nut on it (pic2).

New button time, needs to be the correct one with the same sized slotted thread end that pushes into the cabled section and is grabbed by the clip, there are a few different versions.
