I keep having the same problem. I have the 7133 sewing machine and the top thread keeps getting stuck on the bottom. It's not the bobbin thread that does it but the top thread which gets caught on the hook below. I've rethreaded both top and bobbins and I've cleaned and oiled the hook area, plus used a new needle however it keeps doing it.What am I doing wrong?

You may have already done these steps but when my bobbin stops/starts while filling it I do these steps.
1. Check the thread path to the bobbin area for your machine.
2. Make sure the bobbin is all the way down on the winding spindle.
3. Make sure the bobbin is pushed all the way to the right.
4. Check to make sure the bobbin edges aren't dragging on the guide. I've had this happen and the bobbin will "slip".
If the bobbin is almost full the guide will push it away to keep from over-filling it.
You should be able to control the speed of the bobbin fill the same as you do the sewing feed. Going too fast may also cause the bobbin fill to skip.
Good Sewing!

Good day!

A sewing machine operator can often help themselves when their machine does not operate properly.
Here are some simple instructions, which if properly used can save time and mechanics service calls.
TROUBLE;UPPER THREAD KEEPS BREAKING;
This could be trouble;================Do this;
1.Top tension to tight================loosen tension 1 turn
2.Machine improperly threaded=========check threading
3.Thread twisted on guide post========"
4.Thread twisted out of tension======="
5.Take up spring bent or broken=======Check action of spring
6.Thread jumped off pull off finger===Check threading
7.Needle bent or burred===============new needle
8.Bad cone of thread==================try another cone
TROUBLE;LOWER THREAD KEEPS BREAKING;
1.Bobbin tensionspring to tight=======Loosen tension slightly
2.Bobbin threaded wrong===============check threading
3.Bobbin wound to tight or uneven=====try new bobbin
4.lint or thread on bobbin case=======clean inside case
5.Lint or thread inside hook==========clean inside hook
6.Bobbin case nicked bent or burred===check/change case
TROUBLE;MACHINE STARTED SKIPPING STITCHES;
1.Needle bent or burred===============change
2.Needle set in crooked===============Check
3.Thread jumped off take up spring====check threading
4.Thread jumped off pull off finger===check threading
TROUBLE STITCHES SHOWING LOOPS;
1.Forming loops on top of cloth=======Tighten bobbin tension
======================================or loosen top tension.
2.forming loops on bottom of cloth====Tighten top tension
3.Bobbin placed in case incorrectly===remove and replace
4.Bobbin thread slipped from under====check threading of
tension===============================bobbin case
5.Lint or thread in top tension=======clean between tension discs


Thank you and good luck.

1. Do you mean that there are knots in the bobbin thread?
2. Is the bottom thread in your stitching looping and knotting.

If yes to 1. you need to rewind your bobbin fresh, and keep slight tension on the thread reel that you are winding it from. Put the handle of your scissors into the top of the reel to apply a gentle pressure while winding. Keep your eye on the bobbin as it winds and give it a nudge with a finger tip to ensure it winds the bobbin evenly top, middle and bottom.

If yes to 2, then you need to check your bobbin threading, is the thread even under tension. Is the bobbin tension set correctly. Break out your manual and revisit this to ensure it is set correctly.

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.

have you tried oiling it after you clean out all the dust and thread ends, you can take the feed dog plate off and clean under there as well. hope it helps

you might have a bent needle

try re-threading your machine. usually when the machine is jammed at the bobbin or when the needle gets stuck to the bobbin thread, it means that there is an error with the thread. make sure that the thread isn't pulled through the wrong side of the needle, wrapped the wrong way around the wheels on the top, and that the bobbin is threaded correctly. if this doesn't work, you may want to contact their hotline.

Sounds like you may need to have the tensions adjusted. If the bobbin thread is showing on top, the bobbin tension may be too loose. If the top thread shows underneath, the top tension is probably too loose. Since you are having both problems, perhaps a technician should take a look at it.

Hello,
Here are a couple of things to try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope this helps.

Hi FixYa,

I'm fifi1076, and I'm having quiet a good bit of trouble with my sewing machine.

I'm new at this site so I don't know if I'm doing this correctly or not so please
forgive me if I do something I'm not suppose to do!!!!

I copied this question from off of this site for I wanted to make certain that
whoever answers my question will understand that all of the question
doesn't pertain to my problem.

"when we have it threaded the top thread keeps getting jammed up in the bottom bobbin. if i redo the bobbin as shown in manual then the bottom thread will not loop so it will stitch"

This is the only part that pertains to my problem...... when I have it threaded the top thread keeps getting jammed up in the bottom bobbin......and I can't get it to sew at all....it won't do nothing.....the motor will just sit there and grind.

If whoever can help me with this and can give me a solution I will be forever gratefull

Thanks,

Kay Nowicki
