Sounds like a tension problem. make sure all the settings are correct.
The routine answer is that the top tension isn't working correctly. There may be a bit of lint or thread caught between the tension discs. Try taking a length of thread about 3 feet long and feed it into the tension and pull it out again several times. Thread the machine with the presser foot up until ready to thread the needle. then lower the presser foot and check for tension. If OK thread the needle and begin sewing. If not, start over by pulling thread through the tension.Then repeat trial. If still not OK, send the machine in for service. Good luck.

Hello, sewing is a part of my income and I've encountered this problem before and managed to fix it on my own, by trying out these different things. I re-threaded the machine and checked to make sure that the tension is not too loose. Check the bobin and the sack the bobin fits into, sometimes it comes loose too, click it back into place and re-do the bobin. adjust the tightness of the stiitches, I usually put it on 2 .5 - 3. Hope this helps. Good luck to all. [email protected]

Make sure that there is tension on the thread when you have passed it through the tension unit, by making sure the presser foot is down, and then gently pulling the thread to feel tension. If there is no tension, as seems to be the case, check the tension discs inside the unit to make sure that there is no debris stopping them from closing.

tension could be too loose. start with bobbin tension- should allow thread to pass with SLIGHT resistance. then adjust top tension at about 2-3 to start.

Hi Cat,
This seems to be a common problem, but easy to fix. Check the bobbin, and see if the thread feeds out quickly when holding the thread and letting the bobbin case drop. You should see a small screw on the front of the bobbin case for adjustment. Screw that until the drop rate is slight. You may need to adjust a few times to get just the right rate of feed.
Hope this helps, Please rate and comment, Thank You

try changing the needle--flat side goes to the back of machine
rethread the machine top & bobbin--make sure to use every thread guide
make sure bobbin is wound correctly & inserted correctly in the bobbin case
clean under the needle plate & in the bobbin area for lint or loose threads
