Potential Causes:
Incorrect Threading:
Top Thread Path: Double-check the threading is meticulously correct through every guide, around tension discs, and through the take-up lever. Any deviation will cause problems. Refer to your machine's manual for the exact path.
Bobbin Threading: Make sure the bobbin is threaded correctly as well. Incorrect bobbin threading can lead to issues with top thread tension.
Tension Issues:
Too Much Tension: If the top thread tension is too tight, it will restrict flow, making the thread twist and break. Try reducing the upper thread tension slightly.
Uneven Tension: Ensure your tension discs are clean and the tension setting is appropriate for your thread type.
Needle Problems:
Bent or Damaged Needle: A bent needle can cause thread snagging and breakage. Replace with a new, straight needle.
Incorrect Needle Size: Using the wrong needle size for your thread and fabric can cause tension issues. Refer to your machine's manual or a needle/thread compatibility chart.
Needle Inserted Incorrectly: The needle needs to be fully inserted and with the flat side facing the correct direction.
Burrs or Rough Spots:
Needle Plate: Check the needle plate hole for burrs that could snag the thread. Smooth them carefully with fine sandpaper if needed.
Bobbin Case: Inspect the bobbin case for rough areas that might be catching the thread.
Troubleshooting Steps:
Re-thread Thoroughly: Completely unthread the machine, both top and bobbin. Carefully re-thread, paying meticulous attention to the manual's diagram.
Adjust Tension: Start with the tension settings recommended in your manual. Make small adjustments to the top tension, testing after each change.
Inspect Needle: Closely examine your needle. Replace it if there's any damage.
Check for Burrs: Carefully examine the needle plate and bobbin case for rough spots, addressing them as needed.
Clean Your Machine: Give your machine a thorough cleaning, especially around the tension discs and bobbin area. Sometimes lint buildup can cause unexpected problems.
Additional Tips:
Quality Thread: Cheap threads are often more prone to breakage. Use a good quality thread.
Bobbin Compatibility: Make sure you're using the type of bobbin specified for your machine.
If the problem persists, consider taking your machine to a qualified technician for a more thorough diagnosis.
