Hello, had about 3 years ago my Bonita Retro Star for repair. Since I now live in the Masuria, I have bought a replacement machine. This can not keep up with Bonita. I have now taken my Bonita out of the magazine. I have the impression that it has not been overhauled. When I make myself a coffee, I constantly have ground coffee next to the brew group. It looks like the seal on the piston to compress the coffee has not been changed. Or could it be some other defect.
I set it back to the same setting as always:
water 90 degrees, grind 5. Sometimes it resets itself to 4.
Can you help me?
Would be nice to hear from you.
