The bobbin thread keeps ending up in a big tangle as I'm trying to sew a simple stitch. Bobbin is loaded correctly, thread tension was adjusted both up and down in number, tried straight basic stitches instead of zigzag or button hole. So sick of E6 and my poor three year old is scared of the angry sounds coming out of me as I try to sew a simple seam, which should have taken five minutes, but has now been going on for an hour and a half! Please help. I have a brand new CS6000i model.

I hear what you have done .... try this sequence - Unthread the machine fully. Remove the bobbin. Is the bobbin thread the same as the top thread? Is it a Quality thread (yes, cheapie thread can give big issues!!) Do you have several different threads wound onto the bobbin?? Is the bobbin thread wound on quite tight? If you push your finger nail into the thread wound onto the bobbin, it must not feel soft or spongy. Check if there is any roughness / burr on the any part of the shuttle hook. If so, remove it with 800 grade wet and dry abrasive or similar. Put in a NEW needle as per user manual specs (not a 'new' one you used before 'just for a little bit'.!) REPEAT - put in a NEW needle - amuse me!!. Place the bobbin into the bobbin holder (the CORRECT direction - yes there is a Right and a Wrong direction!), thread it ready to put back into the machine. BEFORE you do, hold onto the thread tail and let the bobbin and bobbin case dangle. Thread should slip thru when you give a gentle pull upwards. If no slip, loosen the tension on the tension finger a LITTLE. If it slides down easy, tighten it a little. Fit the bobbin into the machine. Lift the presser foot (this releases the top thread tension discs) Check there are no bits of thread or fluff between the tension discs Rethread the top thread - check the thread path is 100% correct. Hold onto the end of the needle thread and draw up the bobbin thread. Hold both threads, start to sew - check the result. Tip : If you use a different color bobbin thread (same brand etc etc) it will help you to see more easily what is going on. You should be seeing some of the bobbin thread color on the top side of the sewing. If not, INCREASE top tension a little - retry.If there is a lot showing, decrease top tension. Good luck

Suggest taking the machine back to where you bought it and have them try to help if you are doing something wrong, or replace the machine if it has an internal problem. Good luck!
