Ive just bought a Bezzera Domus Galatea machine. Its beautiful. However, I have had an issue with noise. Specifically, a whining noise.
After ive packed the portafilter, and turn on the machine to start extracting the coffee, the pump can clearly be heard initially. Once that point when the brown base coffee stops and crema starts coming out, the machine has made a very noticeable high-pitched whine. Not quite a whistle, but offputting nonetheless.
Is my machine faulty, or is it something ive done wrong?
