Error Code 0256 - Just before starting or during roast

Taking Care of the Bullet Bullet R1 Troubleshooting
1

Hi guys,
I’m having problems with my bullet R1. All of a sudden, I get error code 0256 right at the beginning of charging the beans or mid-roast. I already updated the software (and downgraded it again to a stable 615 version), changed the power outlet, and did a deep clean. I thought I’d solved the problem and tried to roast a new batch, but after 5 minutes or so, the error popped up again, destroying my batch (second time).

I’m not quite sure what’s causing the issue. I tried all the problem-solving measures I could find online, but nothing helped.

Any idea what to do next?

I can’t see this issue in the logs. Can you send me the link of the roast where this happened?
After you get the error, does it stop heating? Will the error go away after a while?
Also, If you click the “Logs” button on the info screen there might be more useful error codes.
