Sewing machine wont feed thread - Brother CS-6000

SOURCE: Brother Sewing Machine model:CS8150 bobbin thread problems

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

First try taking your bobbin case right out of the machine (not sure if this model has a top loading or front loading bobbin, but your manual will help you here) and floss out the tension slot with a piece of strong thread. Don't use waxed dental floss, but non-waxed would work okay. (The bobbin case is the piece that the bobbin sits in.) Look around while you have the machine open and remove any fluff and thread you can see - TURN MACHINE OFF BEFORE DOING THIS! Replace bobbin case. Replace bobbin and make sure it "clicks" into the tension slot.

Then unthread the top of the machine, clean the tension disks by passing a folded dollar bill (or any paper money, depends on what country you are in) through the disks in the direction you thread the machine. Do this several times. Re-thread making sure you follow the correct thread path.

Make sure the needle plate is on firmly.

If after all that it still won't work, I'm sorry to say that it sounds like you have a misaligned needle bar. This commonly happens after you have a major thread snaffoo and needle breakage. The needle gets caught in the thread knot, pulls to the side and breaks but if it gets seriously caught it can pull the needle bar out of place. You cannot put the needle bar back in place yourself - it's a job for the workshop. Don't sew on your machine until it is fixed. The noise you are hearing is likely to be the needle striking against the needle plate or even the bobbin. Your timing will probably need re-setting too and this needs to be done by a qualified technician.

If you really need to sew before you can get your machine into the workshop, and if you can move the needle position on your machine by pressing a "sideways" button of some sort, you could try to get the needle in the centre yourself using this feature. This will not help if it is the timing that is the major problem.

SOURCE: needle not grabbing the thread

Place a new needle in the machine with the flat side to the back.

Raise the presser foot.

Turn the handwheel until the take-up lever is at it's highest position.

Set the top tension to 5.

Re-thread the machine.

If the thread is hanging up at the spool - this could be the way it was manufactured, a nick in the spool end or the thread is unwinding too fast, puddling and wrapping around the spool pin.

Keep the bobbin case and surrounding area clean and free of thread tangles and snips. Thread tangles in this area can cause the machine to stop.

When the presser foot is down on any sewing machine, the tension closes and you cannot manually pull the thread through.

Sulky and C & C black tends to fray more than other brands of thread.

If the problem continues, the machine will need to be serviced by a professional.
