Perfect !
I have identified your Geberit tank!
Now you need to determine the version of your tank:
Either you have a single-touch trigger plate or a double-touch plate.
Select your version:


I HAVE A SINGLE-TOUCH PLATE!
Go to the maintenance page for your Geberit cistern, equipped with a single-touch system (9 liters) to discover tutorials and original and backward-compatible spare parts.


I HAVE A DOUBLE TOUCH PLATE!
Go to the maintenance page for your Geberit cistern, equipped with a dual-flush system (3 and 6 liters) to discover tutorials and original and backward-compatible spare parts.
