Question about Kenmore 15343

Kenmore sewing machine 15343

As soon as I start to stitch the top thread binds up down near the bobbin, and then it seizes up(doesn't move anymore) If it doesn't seize up the only stitches that stick on the top are the first and last stitch....and It doesnt seem to be incorporating the thread from the bobbin at all. THANKS!

I had this problem but have resolved it (for the most part) by lowering the needle down into the fabric before beginning to sew.

Sounds like your bobbin isn't locked into place. Is the latch on the bobbin worn that you can see? Is the shaft worn that the bobbin locks onto? I'll search for a manual but this is where I would start looking. Good luck

You receive the error message E6 when the motor locked up because thread is tangled or the machine is seizing up.

Remove the tangled thread, it it still happens that means your machine is seizing and requires service.

Model 15243/15343. The thread take up lever will not move up and down

If the thread takeup lever will not move I take it that the machine itself will not move at all which usually means thread stuck in the bobbin case area

How do you adjust the bobbin


Set the tension on the sewing machine for the weight of the material you want to sew. The tension setting shows in the stitch on the material. Use the chart on the machine that matches types of stitches with suggested material tensions. An example of this is, the stitch to sew jean material is different than the stitch to sew silk.

Take the bobbin and wind the thread around it. Make sure the bobbin is empty and don't fill it too full of thread. A bobbin filled too full won't stay tightly spun.

Thread the string evenly on the bobbin. Move the thread back and forth evenly and in layers that are level. Many Singer sewing machines have a bobbin winder on the top of the sewing machine, and the consistency of how it threads can save you frustration later.

Find the hole on the bobbin that is located near the inside spindle of the bobbin. Take the thread sitting on the sewing machines spool and insert the thread in the hole from inside the bobbin to the outside. Set the threaded bobbin on the spool designated for spinning on the top of the sewing machine for some Singers.

Turn the side drive wheel slowly until the threaded bobbin has a layer or two of thread on it. Push down on the drive peddle and fill the bobbin, but don't thread it to the very edge. If the bobbin is too full the thread will release erratically. Cut the thread from the spool.

Drop the bobbin into the bobbin case under the area where the needle sews the material. Close the case and turn by hand the side wheel drive until the bobbin threads into the sewing machine. You can tell when the bobbin is threaded by the tiny piece of thread that juts out of the bobbin case where the needle goes up and down.

Grab the thread with your fingers and pull it out approximately 4 inches. Your bobbin is now spun and threaded.

Hi, my lower tension will not adjust no matter what I try. The top stitching is fine but the lower stitches are very loose. My machine is quite old but in good condition. It is a model 2201 EC1 Series. I...

Be sure to ALWAYS RAISE the presser foot when threading the top thread. This allows the thread to seat completely in the tension disk. The higher the number on the tension disk, the tighter the top tension. If the bobbin thread is laying on the surface of the fabric, try increasing the top tension.

Thread tension is basically a tug-of-war between the two threads. They should exert the same amount of pull against each other. Perfect tension is when both threads meet in the middle of the fabric.

Of course, since your machine is older and parts do wear, your machine may need an adjustment or even replacement of some parts, like the bobbin case. The tension spring on a bobbin case will wear over time and the top tension may lose some of its tension.

TIP: Be sure to treat your machine to some well-earned TLC--cleaning and oiling. Oil dries out over time and will begin to stick parts so they no longer move freely. Below is the method I've used to free seized machines. You'll be amazed at how nicely it runs and your machine will run for many more years!!!

Wheel on right side that controls the needle up and down is very tight...

Oh yeah, here's a manual:
