Thread break troubleshooting
1. Check the thread path to make sure your machine is threaded correctly. It should be
following the correct path detailed in the Threading section of this guide.
2. Make sure your thread tension is correct. Tight tension may lead to missed stitches,
thread breaks, pulling, puckering and thread stress. Loose tension will cause thread to
pile up and loop.
3. Inspect the needle position to determine if an actual thread break has occurred.
Sometimes your machine may read a thread break, but the thread will still be attached
to the fabric. If this is the case, check all the thread paths. Then, do a manual trim
and check the bobbin supply. If the thread is broken, follow the correct thread path and
rethread the needle.
4. Make sure the thread you’re using is not defective. If so, pull out a few yards of thread
until you’ve gotten rid of the defective thread. If that doesn’t work, try replacing
the thread with a new cone.
5. Check for defective needles or needles not inserted properly. You will be able to tell if a needle is
defective or not positioned correctly by verifying if the problem is on one or some needles and not
others. Replace any damage or bent needles.
6. Make sure the bobbin is installed properly. Remove any lint or dirt build-up in the bobbin
case. Make sure the thread trimmer knife is fully retracted.
7. If thread breaks are occurring on all the needles, you need to adjust the hook timing.
Refer to Adjusting the timing of a needle and hook for details.
There are a number of reasons why you may be experiencing recurring thread breaks. To ensure it is not
a technical issue, follow these steps.
