Easy things to try, re-thread the machine and the bobbin. Be sure the bobbin thread is reasonably long (about4 inches). Be sure the needle is threaded from the correct side. Also check for loose threads stuck in the teeth or down in the bobbin case.Click to see full answer. Furthermore, why isn’t my sewing machine catching the bobbin thread? Thread Tension If the tension on the bobbin or the thread through the needle is too tight, it prevents a smooth unrolling of the thread from the bobbin or the spool, and either one or both break. Check your owner’s manual to adjust both the upper and lower thread tensions correctly.Similarly, how do you fix the timing on a sewing machine? Turn the hand wheel slowly to ensure that the shuttle hook is smoothly catching the thread. If it does not, you may need to adjust the timing. Use a ruler to measure the timing settings. Use the hand wheel to put the needle in the lowest position, then raise it 3/32 of an inch. Thereof, why is my thread getting caught in the bobbin? This can be caused if the top thread tension is too tight, or if the bobbin thread is not in the bobbin case tension. Check that the upper thread is feeding freely without obstruction (like getting stuck behind the spool cap or getting caught on any rough spots o the thread spool itself).Why does my sewing machine keep bunching the thread?If there is a difference in thread weights, the machine tends to pull on them at different rates causing bunching. Another cause could be the bobbin case is loose due to a loosened screw. Re-adjust it and tug the bobbin thread gently. It should have some resistance but the thread moves freely.
