Hello,
I get a continuous beeping/buzzing sound when I plug in the Bullet R1 V2 (220v). I took a video.
The sound is coming from the control panel. It almost sounds like a buzzing sound.
It’s a used bullet that I bought it after sample roasting with the seller a couple of times. I do not remember such beeping sound coming out. I brought it home and deep cleaned it following the method on the official website. Could it be due to the electrical components? I can hear a fan inside the control panel spinning as well (maybe the IBTS fan?)
Didn’t want anything to go wrong so I haven’t roasted after bringing it home yet.
Hope someone here can help.
Thank you.
Yes, it is most definitely the IBTS fan. Did you check the RPM by clicking on “i” in RoasTime when the bullet is connected? It could be spinning more than it should because it’s dirty. I mean, you wouldn’t know because you’ve bought it used and don’t know how it was taken care of before. I don’t think you should be super worried about the noise if you’re not encountering errors and the fan does its job, but it should be checked. You’ll find all the info you need in this thread on how to perform the various steps.

Hello,
Thank you for the response and guiding me to the thread! I made a post in that thread but i’ll try to summarize here:
The buzzing noise on my R1V2 (220v) is coming from the IBTS Fan spinning very rapidly (17,400~17,600 RPM). The cause? I don’t know but it’s not due to dirt or dust as I have taken the control panel and the fan apart. Did not notice anything unusual. I will try a sample roast tonight and see how it goes.
Thanks for the reassurance. The noise is driving me crazy though, haha.
Mine is at 14.000 when I turn on the machine. Probably more later, I wouldn’t know. I can hear the noise, so it’s normal you’d hear more of it with 17.500. Since jacob replied in the other thread, he’ll certainly know why your fan is spinning so fast. It might be as simple as atmospheric conditions. I don’t believe you’ll hear it once you put the coffee in, since it’ll be drowned by the noise of roasting.
