My bobbin thread keeps getting tangled and breaking everytime I try and sew....I have tried rethreading the bobbin, taking everything apart and cleaning out the dust and debris, I have adjusted the thread tension but I don't know how to adjust the bobbin tension. Which screw do I adjust? Or do I need to oil the machine? I don't know!

Are you getting thread "messbarf" under the fabric? Try this:

Replace with a brand new needle.
Remove the top thread completely from the machine.
ALWAYS RAISE the presser foot and rethread the top thread.
Check the bobbin--is the thread kind of messy? Try a different one.
Make sure the bobbin case is threaded correctly and the bobbin is installed turning the correct direction.

You may also try changing the top tension.
Wrap the top thread tail around your left index finger a couple of times and then take a couple of stitches.

Try a different brand of thread--some machines hate some thread brands.

If these don't help, then you may need to take it for service.

try changing the needle
rethread using EVERY thread guide
make sure the thread has not come off the thread take up lever
make sure the bobbin is inserted the right way--counter clockwise
make sure the bobbin case is inserted correctly if it's a side or front loading bobbin
clean in the bobbin area and under the needle plate

try changing the needle--make sure it's the correct one for the fabric
being sewed
rethread the machine ---using every thread guide
try using a different bobbin
try turning the bobbin over the other direction
clean under the needle plate and in the bobbin area for lint
also could be a timing problem and the machine would need to be
checked at a sewing machine repair shop

try these suggestions
change the needle
rethread the machine top 7 bobbin ---make sure the presser foot is in the up position before rethreading--use every thread guide
clean under the needle plate & in the bobbin area for lint
make sure the thread has not come off the thread take up lever
make sure the bobbin is turned the right way in the bobbin case & that
the bobbin is not over full

What kind of thread are you trying to use? Is it a decent fresh thread? If, it is old, throw it out and buy some fresh quality thread. Usually, cheap thread is the problem.

Unthread your machine, clean out the bobbin area and brush it, then totally rethread your machine. Make sure that there are no tangles in your thread. Try that, good luck

Sounds like the bobbin is spinning to fast or is winded to loose. Try adjusting the tension on the bobbin.

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.

Hi!

Check to see if the lower thread be tangled. Also, the bobbin could be threaded improperly in the shuttle hook. Rethread the bobbin in the shuttle hook.
How to detangle a thread---

When a machine stops operation due to tangled thread, do not turn the pulley by force.
If the pulley is turned by force then, lower thread might not be picked up correctly and stitches might not be formed correctly.

If threads get tangled, remove a needle plate and cut the tangled threads by scissors or cutter.

Do rate the solution if you find it helpful & useful.

Thanks

Hi, Is it your bobbin thread or the top thread wrapping around the bobbin. I just got a used PE150. The top thread keeps wrapping around the bobbin. It is not picking up the bobbin thread. Did you find a solution for your problem?
