Thread: machine broken??? Brother CS6000i

I have a brother cs6000i....my tension is completely screwed up!! The hubbs helped me take it apart and clean all the dustballs from the bobbin case and.....ewwww! But the tension is still wrong. No matter what number it's on the top thread is little bumps and the bobbin thread is loose...i can pull my thread right out of the bobbin loops. I've tried re-threading, and different bobbins. Now I'm stuck wondering if i should bring it to a shop---which i have no idea who is good here on the island--or just getting a new machine since this one was less then $200 if i remember correctly. So bummed!! I have an antique machine in good condition---still upstate at my dad's. I haven't tried it out yet but the woman that gave it to my mom said her mom used it for piecing and quilting. grrr.

I am having bobbin problems with this machine. I have done absolutely everything that the manual suggests, as well as all that's been suggested here. Thought I had it working for a bit, but I didn't. Not sure what else to do at this point. The machine is a couple of weeks away from being 2 years old and for what I paid for it, I have certainly gotten my moneys worth out of it. Wondering if I should just replace it at this point. Getting frustrated and getting behind on projects.

try turning off the machine and letting the computer reset for a minute.....turn it back on and see if that makes a difference
