Hi!
I'm afraid I don't have anything constructive to say other than good luck. I've googled the model number and it's not a machine we got in the UK, your best option would be to search ebay in Europe and see what comes up! It might have been sold under Volta perhaps?
Best of luck however you choose to solve it, the motor itself should run with just a Live and Neutral from the cord rewind. The PCB just adds the variable power and LED lights, you could always wire a simple Potentiometer in line to turn the speed up and down as a sort of janky middle ground fix. Can't help with the missing filter, I buy Miele cylinder filters and cut them to fit and hot glue if needed!
