    Mazzer KOLD issues

    So I thought it was normal... but I finally found another cafe with a Mazzer Kold and theirs was really quiet... so i sent mine off for repair and it's come back slightly quieter but still not right (and getting worse I reckon)
    I also noticed that the middle burr seemed to be a bit wonky - I've attached a video that should have some slow-mo so you can see it.
    Thoughts?? Does this look normal??

    Hmmm - looks a bit off centre to me. Haven't chewed any large rocks that could have bent the main shaft? (…cold shudder…)

    Almost sounds like the bearings are worn on the rotor. If you (unplug the machine) grab the nut between finger and thumb does it wiggle back and forth even slightly?

    Yup... except it's been like this from day one (really noisy (bearings?) and it appears to be not centred... :/

    A bent shaft would flog the bearings out pretty quickly, "it appears to be not centred" pretty good indicator shaft bent.

    As an afterthought, I'm surprised the repairer you sent it to didn't pick up the issue.
