The top thread won't pull the bobbin thread up. It's threaded properly and the bobbin is in properly. It's an euro pro 464xc also.

Here are the steps to thread a Euro-Pro 382 sewing machine:

1. Raise the presser foot lever to release the tension discs.
2. Place the thread spool on the spool pin and slide it to the right until it clicks into place.
3. Pull the thread end from the spool and insert it through the thread guide located at the top of the machine.
4. Pull the thread down through the tension discs, then wrap it around the bobbin winding tension disc located on the top left of the machine.
5. Insert the thread end through one of the holes on the bobbin and push the bobbin onto the bobbin winding spindle.
6. Push the bobbin winding spindle to the right to engage the winding mechanism. Hold the thread end and press the foot pedal to start winding the bobbin.
7. When the bobbin is full, cut the thread and push the bobbin winding spindle back to the left.
8. Remove the bobbin from the spindle and place it into the bobbin case.
9. Hold the thread end and turn the handwheel towards you to raise the needle to its highest position.
10. Pull the thread from the bobbin case and insert it through the thread guide located above the needle.
11. Thread the needle from front to back and pull the thread out about 6 inches.
12. Lower the presser foot lever to engage the tension discs and pull the thread towards the back of the machine.
13. Hold the thread end and turn the handwheel towards you to take up the bobbin thread.
14. Close the bobbin cover and you're ready to start sewing.

Please check whether it is the bobbin thread or the top thread that is messing up. If it's under the fabric, it is 99% the top thread and is called bird nesting or thread nesting.

Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Also check that the bobbin is loaded and turning the correct direction in the bobbin case.
Now, retest the machine.

You may need to tweak the tension to get it where it looks best.

...

Try installing a brand new needle. Bent/damaged needles will sometimes not pick up the bobbin thread.

Make sure the machine is threaded correctly. Check the bobbin--ie, it is turning the correct direction in the bobbin case and is threaded properly through the bobbin tension.

You might also try pulling the bobbin thread up to the top before beginning to stitch.

...

Either your machine was not threaded with the presser foot wasn't up when you threaded the upper thread... or your upper tension isn't tight enough.

Good luck.

Good day!

5.Lint or thread in top tension=======clean between tension discs


Thank you and good luck.

The top thread is loose and the bobbin thread is pulling the top thread down

Always thread the machine with the presser foot up and see if this eliminates the problem.

Sounds opposite of the problem, but it is very important to do this to assure the tension control can keep the top thread at the correct tension to form a proper stitch.

If the machine is threaded with the presser foot down, the tension control is closed and the thread cannot seat into the control as it should.

Home use machines have a very difficult time with heavier thread, you are OK with size 50 and the larger size 40, but not with anything thicker. You can maybe get away with your thread by turning the upper tension higher, try it with the tension at 7 or 8 or 9, it "may" give you better results.

Just a note of warning, that thread may jam the machine and break your gears or your bobbin case.

Try adusting the bobbin thread instead of the top. Always make sure to insert the bobbin so the thread is pulling in a clock wise direction. Both threads top and bobbin should have about the same resitance when pulled.

Have you tried flipping the bobbin in it's case, so that the thread comes off the top of the bobbin instead of the bottom. Some machines are sensitive to one direction of the bobbin thread.
