BOBBIN winding error Singer Brilliance 6180
Hi yall
I'm looking for some help while troubleshooting my Singer Brilliance 6180. I have been servicing my machine, oiling it and removing any loose threads and lint. I have run into an issue when loading a bobbin with a new thread. When the bobbin threading is engaged (moved to the right), the empty spool for the bobbin will spin for a moment, loading some of the thread and then abruptly stop. When it stops, it displays a C4 error. Looking at the manual for this machine, C4 error only displays when the BOTTOM BOBBING PLATE IS TRAPPED WITH THREAD. When inspecting the bobbing threader and the bobbing case, there does not appear to be any trapped thread.
It also sews completely normal when it is set to the left. So it seems like an error specifically relating to Bobbin threading with new thread.
Has anyone come across this issue?
edit: The belt seems to be correctly in place and in good condition. I have already corrected the timing between the top and bottom thread so it's not related to that either.
whats odd also is when I set the top spool to the left, it does not display the spooling symbol that looks like this
