Today, my machine ERC 6864 & ERC 0004 errors while I was roasting coffee. The IBTS fan was operating normally at 5850-16000 RPM, and the room was air-conditioned at 27-29 degrees Celsius. My machine is an R1 V2.
I opened the panel and checked it, and there were no issues. However, today the fan noise was a bit too loud.
Is this a bug? Does the fan need to be replaced? How can I fix it? And where should I find parts if I need to replace it?
Where are you located?
This is most likely due to the IBTS Fan not freely spinning or the IBTS sensor needs to be cleaned.
