SIMILAR PROBLEM OF TOP THREAD ACCUMULATING IN BOBBIN AREA

a part of the bobbin winder is not working and should be checked

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

taking the machine back to hancock fabrics is a good idea
and let them show you how to do the bobbin

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.

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.

try a new needle

rethread the machine top & bobbin, that way you make sure the thread is not caught anywhere

make sure the bobbin is correctly inserted in the machine

clean under the needle plate & in the bobbin area for loose thread & lint

always keep a long thread tail of 3 to 5 inches long, & keep the tails pulled back behind the needle
before sewing

if none of these things help the problem,, then it may need to be serviced

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

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

There are several possibilities, take a look at earlier solutions page for similar problem Here

I would also suggest a Q-tip or cotton bud dipped in metholated spirit to clean the bobbin case area, especially the recess track where the bobbin case spins.

If there are any needle strikes on your bobbin case which have spoiled the smooth surface required for efficient thread movement over the top, get a replacement for a few dollars.

For the record, Janome gives a 5 year warantee on circuit boards, so in the unlikely event that they fail, free replacement.

What do you mean you are unable to pull the bobbin thread through, elaboration would help solve the problem...
I suspect I'm having the same problem with you if it's anything to do with the top thread looping around in the bobbin holder.

Damn machine!
