Question about Eureka Mignon Perfetto Silent

I have been using this grinder for a full year now and my grind settings are completely off. I must be in the far "turkish" area to get something close to espresso grind. I read online that changing burrs could solve the problem but it seems impossible to find a replacement set of burrs, even through Eureka themselves. Did someone encounter the same issue or know a place to get a fresh set of burrs ? Thank you for your help.
