    Musical Silvia

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All,

    Ive had my Silvia for about two months now. And noticed once it has been on for a while and well and truly warm it becomes musical. Towards the end of the heating cycle it makes a harmonic humming sound that moves through a range of pitches. Certainly dont think its anything bad, just interested to see if anyone else has noticed this? Or is it just common to all machines with a boiler? Im guessing it is just hot brass resonating from the steam.

    Cheers

    I have noticed various musical sounds emanating from my Silvia at various times, seems to be more common after I have descaled her boiler.

    Mine does it too, towards the end of the heat cycle.
