Thanks for the quick response. When I grind beens. I think it's burrs. Certainly not the engine. This is not a regular sound. I cleaned as always. Brush and according to the instructions. A message to customer service is a good idea, but I thought it might be a trifle, and someone had a similar problem.
Hello there. I have problem and I hope you could help. My Baratza 270w sgueaks after cleaning (like a mouse) . I cleaned the grinder again and did not help. I put in new beans and changed setting. It also did not help. Do you have any ideas what can I do next before I will send to service? Thanks and I look forward to your response.
