Button on tiled in toilet cistern not working

[Nickfromwales]

You must allow for the worst case, which is that the hose has become fractured and you need to get it off the bellows as well as off the button, so it can be replaced.

There's a plastic lock nut on the back of that, so if you keep messing with it the push button will be dangling by the pneumatic hose and the locknut will be swinging around on it behind the wall / tile.

 

You might be able to get it out by pulling it tight against the back of the panel, rotating it a bit anticlockwise then pushing it back in for another go etc.

 

Then as @Nickfromwales says you will get access to the whole pushbutton assembly and the flexible pipe. Make sure you tie string round the nut. Then you can maybe see what is wrong with the pb. If fixed you could then glue it back with something like CT-1.

 

My worry would be that the fault is the other end, at the cistern. Which if true will mean you have the problem of getting at that as the numpties have left no access to it.

 

We have a similar arrangement but the entire panel is on plastic hooks and slides upward for removal. Maybe you are looking at too small an area? Just a hope...

Another job for a cheap inspection camera with a fiber probe ?

Here's one I found earlier  🫡

Sorry to say this but.  “I’m staying at a friend’s, ”.    It’s not yours🤷‍♂️, however like others I believe removing the cill will give better access, perhaps cut all silicone surrounding it to see if it will move,

@Jilly, if it's like I suspect it MIGHT be - there's in all probability a push-rod behind the button.

The 'stroke' of that button may be adjustable.

If I'm right thus far, then all you might need to do is rotate that push-rod clockwise or anti-clockwise such that the rod extends outwards (towards the user) a bit. If it's an old design, the linkage will be brass, and might be clogged up a bit. If its plastic, then you're in luck.

If you are able to screw in (or out) that may well mean that the mechanism engages that bit more with the innards.

 

It could be that the button itself is firmly attached to that push-rod - in which case, does the button itself rotate?

I had a loo in Berlin that was just like this - it had a sloppy linkage (as in there was lots of play in the various bits) design.

(Yes, there was an inspection panel in a cupboard next to the pan 😐)

The button doesn’t seem to want to rotate.
 

I’ve got a little toy endoscope for things like this, but there isn’t a big enough gap to push it through.

But it is not tiled over and can lifted out very easily.

I didn't mean to make you frown. I meant to imply a positive, that taking the tiles off the sill might allow the board to be removed and voila, all within easy reach. The cistern will be immediately under the sill, and the button to flush connection right. there too.

Also that removing tiles from the face might be pointless as all you will see is the face of the tank.

 

there: it's good news. ...probably  :  but best wait  a bit and allow others to cry Don't, if they disagree.

Having recently had to deal with a leak for my sons “hidden” cistern, it’s best to sort easy access now and not wait till water is flowing everywhere 🤷‍♂️
