Please help me resolve this issue

Try re threading the needle. and try a new needle. Make sure th thread and needle are the size required for the material used. Make sure the needle tension is correct for the material. and also that the thread is not old and the same thread in both bobbin and needle.

Please describe further what you are seeing on the seam? Loops on bottom? Loops on top?

if the bobbin stitch is loose tighten the top thread tension one number at a time & sew alittle bit & if it's still loose tighten it one more number till you get the correct stitch

Lauren, were you able to solve your problem. I have the exact same machine and am experiencing the same problems that you state.

Kind regards,

Well is your machine skipping stitches? "Not looping" does that mean not creating a stitch? To adjust your bottom stitch you usually adjust the top tension regulator. I can try to help you more in detail check out my forums http://www.sewingmachineryrepair.com/forums/index.php

When the bottom stitches are loopy it is the top tension which is wrong. I suspect that it is not threaded correctly for it to be this bad. If you have a tension dial make sure that the thread is properly between the disk. Try the top tension on 4-that is an "average" normal setting. Gradually turn it up as needed. A good way to test tension is to use 2 contrasting colours-red and white are good. You will see at a glance where the problem lies and how well you are correcting it with adjustments. You should barely see a trace of the top colour coming through. Rethread the machine top and bottom with 2 colours-set dial to no 4 and go from there.

Hi, general rule of thumb:: loops on the top, problem on the bottom.. Loops on the bottom, problem is on the top.. When threading your machine, stop just before you thread your needle, put the presser foot down. Try pulling the thread. If it pulls easily, the thread is not thru the tension wheel right. If it pulls hard, you got it right.

General rule of thumb is this.. If it loops on the bottom the problem is on the top..
If it loops on the top, the problem is on the bottom.
Sounds like #1 your bobbin is wound very loosely , #2 your bobbin thread has to go thru its tensioner.

Looping on bottom:
Great description, that helps a lot. Big loops are actually easier to solve usually. 1st know this: Loops on bottom means the top is too loose or the bottom is too tight. With loops that big its probably the top is too loose. 1st look in tension disks, there is likely a chunk of thread in there. A toothpick is handy to dig it out (the flat kind) 2nd make sure that the thread is getting between the disks when threaded. 3rd Make sure the thread is in the take up lever (the thing that moves up and down in front and not the needle bar or any part of the needle bar.) If neither, then the bobbin case could have a burr on it and the thread is hanging on that burr. Also the bobbin case may be in wrong. I hope this helps

Sounds as though you may have a burr or rough spot on the hook where the bobbin inserts. Run your finger along the edge of the hook to see if there are any rough spots.I'm sure you're going to find at least one from the time you broke the needle.Once you locate it, remove it with an emery stick or small sharpening stone. Polish it so that it is smooth. Should work okay.
