Toilet won't flush - help identify this panel

[mysparkleismissing]

Hello there

I wonder if anyone can help identify this panel to help us get into it see if we can solve the issue... Google isn't currently helping

Am hopeful someone can help!

Looks like a standard Geberit panel. We have them - the design is such that if you flip off the button panel you can reach through the hole to all servicable parts. However if you don't know what you're looking at once the panel is off you're better off getting someone in.
