I purchased a White Sew E-Z Model W338, 3days ago, and I cannot get the bobbin thread to come up with the spool thread so that I can use the machine.

No, sewing machines that use bobbins don't have an adapter like that. It would be difficult to get the bottom tension right working off the spool. The best solution is to fill several bobbins in your thread color before starting to sew. Then when you run out, swap in a new bobbin.

Some advanced machines will warn you when the bobbin runs low. (I've seen the feature on the machines with touch-screens.)

I wish that I had better news for you. A serger might be a an option to consider. They don't use a bobbin and can be used for some sewing projects. You can still run out of thread on one cone before the others run out. (Those machines use 3-4 threads at a time for the basic stitches. The knife can be lowered if you don't want to trim your fabric while stitching.)

(I've got a Singer Touch and Sew and usually don't run out of bobbin during a seam. I will swap bobbins when they are still 1/4 full at times if I get concerned about the bobbin running out.)

The spool could be in the bobbin backwards. It might not be threaded properly. The needle could be in improperly.

I presume you want to twin needle sew?

So you need to have two thread spools on pins to do this. Most machines will have two spool pins at the back for this purpose, sometimes they are retractable pins so you would just need to pull the second one up.

or sometimes a seperate pin in the accessory box that you can mount onto a hole somewhere for this purpose.

Rather than buy two reels of thread in the same colour to twin needle sew, you could also wind a second bobbin off (only half full should be plenty), then pop this onto one of the pins and the main thread spool on the other.

Hope this helps you out, I couldn't actually find an image of the back area of this model but most quality machines have two pins as standard.

You haven't given a lot of details so I'll just assume this is a bobbin issue initially.

Take out the bobbin and rewind a fresh bobbin of thread paying attention to the following.

You want to keep a bit of tension on the thread spool as the thread winds off it - good way is by placing the round handle of a pair of sewing scissors onto the top of the spool. If you let it just bounce around it will affect the bobbin winding neatly and the thread won't then run off the bobbin smoothly as you sew.

Also visually watch the bobbin as it fills, and give the thread a nudge with your finger tip to ensure it fills top and bottom, not just in the middle.

Think of how you wind up the garden hose reel, if you let it all go in the middle, it jams up before the whole hose is wound onto the reel. But if you wind it carefully and move the hose around winding it evenly across the whole reel, it stays neat and doesn't all jam up. Same principle for bobbins; don't just run the thread through the little tension disc and press the pedal hard until it stops.

Also quality of the thread is important; cotton wrapped polyester is nice to sew with and has a bit of spring, strength and good sheen; not sure where you are. But the brands I look for are Sylko Supreme, Guttermann and Mettler threads; there are other good brands too. Don't use those cheap bags of 5 white or black thread in the bargain bin. Some threads you can actually see particles of dye coming off the thread around the spool holder as you sew. Darker colours do this more.

And keep your threads stored neatly in air tight containers away from light, insects or damp; textiles fade and break down under UV rays eventually.

Now rethread your machine and ensure that the bobbin has gone into the bobbin holder winding in the correct direction for your machine, and that the thread has clicked into the tension spring.

Check the thread spool to see if there is a nick where the thread is catching. If there is, you can smooth away the nick with an emery board, or just flip the spool so the thread is feeding from the bottom of the spool.

Sometimes the thread feeds too quickly from the spool and puddles around the spool pin. A thread net (can be purchased online or at a sewing machine dealer) can eliminate this.

Check the threading to be sure it is correct - always thread to top thread with the presser foot up.

Check the bobbin to be sure the thread is feeding from the bobbin spool in the correct direction and through the correct guides.

Refer to your manual for threading and bobbin position.

Hello,
Try these solutions

* 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, Hold the upper and bobbin thread tails 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.

You ought to have a 3 mth warantee with this used machine, take it back to the dealer and have them fix this problem...in Australia, consumer law provides that the sale of goods requires that they are "fit for their intended purpose".....there is almost certainly a similar provision where you are........get it remedied soon, as a feature that has not worked since you purchased ....perhaps calling first to ensure you are able to meet with the service person to explain.

I would not recommend you open it yourself until the dealer has looked at it.

If they cannot fix it, ask for replacement or money back.
