Question about Janome Memory Craft 9000 Computerized Sewing Machine

3 Answers

I have a Janome 6500 (not on your list, but........) The thread breaks every few inches. It is the top thread that breaks, but it breaks in the bobbin area. I have taken it to my dealer twice, but she can't find a problem. It has been cleaned and oiled. I put in a new bobbin case, tried different threads and different tensions.

    One clue I have is that the thread shows signs of fraying and/or abrasion at the breaking point (as opposed to a definite clean cut). Oh yeah - I have tried 2 or 3 new needles in different sizes, too.

    I just added the comment that I have tried 2 or 3 different needles (all new) in 2 or 3 sizes.

    What is the auto tension selector?



    The 6500 has a knob that is turned manually to adjust the tension. And yes - I have tried various tensions. There is a limited range at which I get acceptable stitches.

Are you using the auto tension selector? Or do you adjust your tension. Since it works well with the monofilament/cotton combination, you may need to adjust your tension for other combinations even when the top and bottom thread are the same kind of thread.

    It sounds like you've already tried the usual things to remedy a thread break (experimenting until you find the needle/thread/tension combination that's
    "The Sweet Spot", bobbin replacement, etc).

    The only other stuff I can think of are lint & proper oiling. When you take the bobbin housing apart do you see any lint? It could be possible that you may have a very small piece of lint in the upper tension. Also, is the bobbin housing oiled?

    Some people suggest putting your top reel into a mug behind your machine so it moves freely. What type of material are you sewing?

    I contacted the administrator of a well known sewing site about your problem, this is what he had to say, "The main reason for fraying thread is by using a needle with the eye
    being too small to carry the threadyou are using. You stated that you
    have changed the size of the needle. Try using an even larger needle
    and see if that helps. If not, I would think that there is probably a
    chip,scratch or burr either on the hook or the bobbin case. You stated
    that you have had a mechanic look at your machine, so this is more than
    likely not the problem. You might try looking at the spool pin/holder
    and the threading chutes for chips,scratches or burrs. I hope this
    helps, but it seems you have covered all the bases. Maybe one of these
    things were overlooked. I wish you success."

    I e-mailed Janome about your problem, this was their response:
    "
    You didn't say whether or not the thread would break when your dealer was stitching on it? Double check the threading and make sure that the thread is not getting caught on something and that it is threaded correctly. Let your dealer know that the problem is still occuring and the dealer can contact the Service Dept. as to what is happening with the machine and they can discuss possible causes. If necessary the Service Dept. can make arrangements for the dealer to ship your machine

    to our Service Dept. for repair.



    Machines sent to us for repair must come to us through an authorized Janome dealer. Janome does not accept machines sent for repair directly from the consumer. You would be responsible for shipping and labor charge and any part that is not covered under warranty.



    Thank you for your inquiry,

I have a Janome 1600P and the top thread keeos breaking


There are several common reasons for upper thread breakage.

Check that the needle/thread/fabric are compatible.
All About Needles

Remove the upper thread from the machine, install a brand new needle, ALWAYS RAISE the presser foot, and rethread from the beginning. Verify the thread path is correct. Set the upper tension to the midway point.

Check this in your manual. I think when you do free motion you have the feed dogs (toothed things the rise up and pull the fabric under the presser foot) locked down but you still have to have the presser foot lowered. When the presser foot is locked in the up position, the tension on the bobbin thread is released.

Have a Janome 1600P-Top thread keeps breaking


The top thread breaks

1. the needle thread is not threaded properly

2. The needle thread tension is to tight

3. The needle is bent or blunt

4. The needle is incorrectly inserted

5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew

6. the threads were not drawn to the rear after sewing

7. The thread is either to heavy or to fine for the needle

8. Try a different spool or cone of thread

Hi. It may be that you need to adjust the tension. Put a different color thread on top than is in the bobbin and sew a couple of inches, then check. I suspect you'll find that the top thread is the one that is loose and knotting up. (It's hard to tell unless you're using two different color threads.) If that's the case, your upper tension needs to be tighter. Tighten it just a bit, then sew a few more inches and check again. Repeat until you don't see any of the top thread on the bottom (or maybe just a little bit) or the bobbin thread on the top (or maybe just a little bit.).

Hope this helps!
