Hello everyone, I just bought a bullet r1v2 for 3 weeks. I have been roast 8lbs coffee beans. And I do cleaning the machine everytime when I finished the roast.
Recently, druing I roast coffee bean, the bullet will sound Beeee. and show The A-02 error code on the screen. Does anyone know how to prevent that happen or what is going on the machine ? Thank you !!!
It is the dead man switch.
It’s a good idea to read the whole manual so you understand how to safely use the Bullet.

One way to prevent the dead-man switch from screaming at you is to use the buttons on the panel to change your P, F and D settings during roasting rather than the software.
And as Jacob said… do read the whole manual first so you know which buttons are for what.
