Printed Jura F8, Defekt

Two weeks ago, a buzzing noise was heard for the first time when serving coffee. It has been gradually increasing since then. The dispensed amount is continuously decreasing - estimated now only 70%. The machine is 8 years old and has run without problems since then. I would appreciate any helpful ideas. Am an experienced tinkerer. Or is this the beginning of the end?

Has the brewing unit ever been revised? Would be necessary after 8 years.

You can do it yourself if you don't have two left hands.
Either you get a refurbished or new brewing unit, or you remove the old one, disassemble it, clean it and reseal it.

You will need an oval head wrench for this. Instructions and spare parts can be found at the usual dealers on the web.

Your advice has helped me a lot in the orientation. Youtube videos have made me realize the complication of restoring the brewing unit. As a result, I decided to buy a new machine. I will try to sell the old one on Ebay. Thank you very much for the help.
