Most of the time it is in your top threading or a bad needle. Try this and if it doesn't work call Singer at 1-800-4singer. I am hoping that it is not the timing. Good luck

    Try putting a different color thread in either your bobbin or your top thread and you should see that it is the top threading problem.

Not stitching. Can timing be adjusted


If you had no major jam your timing will be fine. My guess is that you have a problem with the needle positioning and/or adjustment of the machine itself. Like, check that thread is not knotted and looped correctly. Do some basic checks (as per manual) and don't panic.

The lower stitching on my machine is not consistant, why?


Wrong size needle or wrong type of thread for the weight or type of fabric. For instance, you should use smaller needle size for light weight fabrics.

I have cleaned the machine. I have tried both solitions in my Jaome machine and still loops are forming on the botom. i have even moved the little screw on the bobbin- tested the thread and changed the...


If the loops are forming on the bottom it is the TOP thread tension you need to check. Make sure it isn't too loose. Also is the needle the right type and size for the fabric? Check the stitch out on plain cotton fabric if a tension adjustment doesn't fix it.

The TOP thread effects the UNDERSIDE of the stitch and the BOBBIN thread effects the TOPSIDE of the stitch :)

Stitches are looping on the underneath and missing some stitches


Refer to the manual for cleaning.

Replace the needle with the size recommended for the type of fabric being sewn. The flat side of the needle is usually facing the back of the machine - check manual to be sure.

Always thread any sewing machine with the presser foot up. This opens the tension control so the thread can properly enter this device.

When a sewing machine is threaded with the foot down, the tension control closes and the thread cannot enter as it should

You then get loose stitches because the top thread and bobbin thread cannot make a proper stitch and the tension of the bobbin thread is pulling the top thread to the underside of the fabric.

Kenmore sewing machine #16227 needle thread making big loops on wrong side of fabric. Changed needle, cleaned, adjusted/readjusted and readjusted needle and bobbin tension. Will sew a decent stitch...


It is most likely because you have it on a type of stitch but did not switch the didstance that you want the zig zag to be. Just change you stitch or your distance.

Tension problems


Hi, check that the thread tension knob makes only one rotation from 0 to 9 and stops at each ends, see that it moves in and out as you increase or decrease the tention, see that the small tension wire to the left of the knob is still in place, in any of these fail you need to replace/repair that assembly.

Juki HZL-E61: cannot get tension right on straight stitch


Loops on the bottom of the fabric direct the problem to the top thread. Rethread again and make sure the thread goes through the tension discs. Lift the foot, because this is what opens the discs. When sewing and the foot is down, the discs should be closed and thus giving the upper thread the tension it needs.

When feed dogs down top stitching fine ,but underneath large loops and cobbling settings are as per instructions in manual , ? problem


Have you checked to see if the Thread has slipped out of the Tension guides? Here are my quick steps to getting back to happy sewing:
  1. Remove bobbin and blow out the dust from in and around the bobbin case, when replacing bobbin... make sure it the thread is traveling the right direction in the bobbin case. (this one never hurts to try, a backwards bobbin causes lots of probelms)
  2. Re-thread the machine (the thread in my Janome sometimes comes out of the thread uptake lever causing the problem you described, could mean your threading path might need to be cleaned)
  3. New needle (the tiniest bent needle can cause hair pulling issues.)
