Bathroom Sink issue

[Andy1954]

We have a Burstner Brevio which we love. Noticed last time out the slide away sink appeared to have dropped a little. I have attached a couple of pictures showing what’s wrong. Does anyone know how I can get into the top pivot without taking the wall out, to see what the problem is.
Thanks
Andy

Bummer! Looks like the wall is going to have to come out.

If it’s like my brothers burstner it’s a few screws to remove wall

Before I do that, I’ve ordered an endoscope so I can hopefully see what’s come lose
