Janome Sew Mini bobbin problem

Thanks for taking a look at this ...... You answered this once a few months ago, but addressed looping under the fabric, I believe the problem is bunching of bobbin thread under the pressure foot plate.  I was using my new machine for the first time, straight stitch and reverse were fine for about 36 inches, then, the bobbin thread started to bunch up (under the plate), and stop the sewing.  I put the foot up, moved the needle up, pulled out the fabric, and the bunched up bobbin thread pulled out of the chamber unknotted  along with the needle thread... only one stitch was in  the fabric. I have tryed cleaning the bobbin chamber, rethreading  the bobbin, followed the manuals  directions.... there is no answer for this  problem  in the manual... thanks much, Kim

Hi, Usually wrap-ups in the bobbin area are caused by the lack of tension on the top thread. The slack arm ( shinny lever that moves up and down while sewing) has to pull the loop around the bobbin case and it does so only if the tension on the top thread is sufficient to keep it from pulling more thread of the spool.
Try this: Thread the top of the machine all the way just short of the needle eye. When the presser foot is up the thread should pull through easily. Now drop the presser foot (this closes the tension discs) and pull the tread while adjusting the upper tension control.
If everything is working correctly you should feel the drag on the thread change if not something is keeping the discs from closing.
Most Janomes aren't too difficult to remove the nose cover, usually just one screw and you can get a look at the thread path. Look for thread wrapped around the mechanism.
Sorry, no easy answer but I hope this helps.

SOURCE: tension

Check your tension disks, with your presser foot up, and the tension dial on zero. Sometimes a piece of cotton breaks off between the tension disks and then prevents the disks to work properly. Also make sure when you thread the machine, the thread does go through the disks and over the take up lever. After you threaded the machine, before putting the thread through the eye of the needle, lower the presser foot and while pulling on the thread with your left hand, increase the tension with your right hand. Do it slowly and you should feel in difference in tension. If this is the case, your machine should work fine.

SOURCE: Machine not sewing

Make sure you have threaded the machine from right to left, it sounds like the needle thread is trapped under the lower looper thread and cannot form a stitch.........start the threading over from scratch like this:

  1. Lower Looper
  2. Upper Looper
  3. Left Needle
  4. Right Needle
Is there a diagram for how to thread on the inside of the door ?

Follow that slowly and carefully to make sure you have not missed any thread guides on the way, as each one needs to be followed through to ensure correct tension and thread progression.

If you are certain that all threaded correctly, did you have a fabric jam and pulled it loose ? If so, the timing may well be affected.

Post an update and we'll get this right.

SOURCE: Thread is bunching underneath fabric

Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.

SOURCE: janome straight stitch loose

I don't know if this is the right answer for any of you, but thought I'd put my 2 cents worth in. Often this can be the bobbin in backwards. It needs to unwind a certain way depending on the machine. I've heard a phrase for this: Mind your p's and q's which means some wind off to the right like a q, others to the left like a p. Mine has to unwind one way then be slipped backwards into a little slot or it does that loose bottom thread looping and bunching someone here mentioned. It seems everytime I get that problem I rethread the top thread 100 times before it clicks again and I remember it could be the bobbin thread. Either your manual will tell you the correct way, or you could experiment and try one or the other. Once you figure out whether you're a p or a q, mark it on your machien somewhere to remind yourself.

Good Luck and Happy Sewing!

SOURCE: Top thread stitches correctly but bottom thread loops.

FYI---- Loops on the bottom-- problem is in the threading..
Loops on the top--- problem is with the bobbin.

John Lewis mini sewing machine


This was really helpful for me fixing my daughter a John Lewis (janome) mini sewing machine, and now can get the bobbin thread up again, however, when you sew, the thread is not staying in stitches, just coming off the material completely. I tried forcing the gears on one more time but then it didn't pick up the bobbin thread again so went back to the other gear position. Any ideas of what to try and get it stitching again? Thanks

Bobbin case catching thread


I believe that you are talking about the assembly that holds the bobbin case in. The bracket that holds the bobbin case in must be adjusted to allow the upper thread to slide by. Check if the thread will go by this area without "hanging up" while rotating the hand wheel. Also check your bobbin to make sure you have the right one. If it is too high or wide it will definitely be a problem.

Janome mini heavy duty sewing machine


when you sew keep a eye on the thread take up lever & see if the thread comes off while your sewing, I've had this happen to me & I've been sewing for over 30 years. if this does happen, take a pair of pliers & very gently close the take up lever just alittle but not enough to damage it.
also check the needle to see if it's damaged--if your not sure change the needle--flat side goes to the back of the machine
always make sure the fabric & needle & thread are compatable--the thread must be able to pull thru the needle with out any problem
also check to make sure there are not any burrs on the needle plate or bobbin or bobbin case

Hiya Kandie. Usually when you can't pull the bobbin through, the wrong size needle is in, try a different size needle. Hope I was some help for you.

Oil the machine first. Then, determine whether or not you need any parts at all.

Have you tried a new needle?

If re-threading, changing the brand of thread, etc. does not work, then it's likely your machine is out of time. Search for sewing machine timing or take it for service.
