Threading with the auto cartridge

HI Elizabeth.
Found this on the internet.
There could be several things that could cause the machine not to pick up the bobbin thread.

• The upper thread could be tangled.
  Remove the thread completely from the machine.
  The correct size spool cap should be used for the size of the thread spool.
  Re-thread the machine according to the directions in the manual.

One Point Advice Upper threading

• Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race.
  Remove any loose threads or lint in the shuttle race.

One Point Advice Installing a bobbin into a bobbin case

• You could be holding the needle thread too tight.
  Hold the thread lightly to keep the end from going down into the shuttle.
• The needle could be thread incorrectly.
  Thread the needle eye from the front to the back.
• The needle could be bent or improperly inserted.
  Install a new needle with the flat side of the needle facing the back.
• if this does not help you go to this link.

Difficult to say. The manual doesn't seem to mention using a double needle. However, frequently, the the bobbin loads from the top or the front, there is a possibility a double needle will work.

Be sure you are using the correct needle and thread for your project. Use a ball-point for knitted fabric. Also, be sure to thread one top thread all the way through the needle and then thread the other thread. Do not thread them at the same time as the threads will twist. If your machine has separators in the thread path for separate threads, be sure to separate the threads. (Most likely your machine does not have separators since there is no mention of using double needles.) ALWAYS THREAD with the presser foot raised.

If by "won't stitch" you mean that the top thread will not pick up the bottom thread, make sure you have the needle threaded properly. If the machine is a top loading bobbin, the thread goes in the needle from front to back. Same if it's a side loading bobbin (bobbin faces you as you sew). If it's a front loading bobbin (bobbin faces left of machine), the thread goes in the needle from left to right.

you thread the machine the normal way, using every thread guide, and if the automatic theader works it will thread the needle,
if the auto threader doesn't work, then it needs to be checked.
also make sure the needle is turned the correct way and inserted correctly into the needle holder.

make sure the thread has long thread tails of 4 to 6 inches long
and have the thread tails pulled behind the needle before starting
to sew.

have you tried using a new needle- if the needle is the slightest bet bent or or damaged it can cause problem with the fabric threads

if the needle is not the correct one for the fabric, it can move or damage the fabric threads

also clean under the needle plate for loose threads or lint also in the bobbin area

that use to happen to me on my sewing machines, I would rethread the machine to make sure the thread is not caught on anything like the thread spool, or around anyone of the thread guides

also for both top & bottom threads, I keep a thread tail of 3 to 6 inches & before I start sewing I pull the thread behind the needle to the back of the machine & the I put the fabric under the foot & start sewing & now I don't have that problem anymore

The bottom thread won't come up?
Make sure you:
-Have the top threaded and through the eye of the needle (Basics are best to check, I've missed it once or twice! lol)
-Are holding the tail of the top thread when you lower your needle and pull it back up (Hold it too tight though, and it might not grab)
-Have an inch or two of "tail" or extra thread for the needle to grab on your bobbin thread (sometimes it won't grab if there's not much there)
-Have all your lower pieces in and secure. (Mine tend to jump around if I'm not putting 'em in right)
If it's still not grabbing, I'm not sure. Sorry, hope it helps.

I have had the same problem ever since I got my machine (when it first came out). I think I've figured it out! At least partly.
1. Take the thread cartridge out.
2. With left hand, reach under and gently pull auto-threader down (on the outside of machine - by needle).
3. While pulling it down, keep an eye on the inside. You should see and hear something click as you pull it down.
4. Now you can let go of auto-threader (gently) and replace thread cartridge.
5. It should auto-thread properly now. It will probably do this again, so just keep an eye on it.
I hope I've been clear enough. If you have any questions, just let me know.
