I have a siplicity sewing machine and after taking the bobbin out to clean it I cannot get the bobbin holder to go back intot the machine

I would find a local sewing machine sales and repair shop near you. You will need to have them look into this, it may be a timing issue or a broken or damaged part.

sounds like you have thread bunched up in the bobbin case. take out the entire bobbin plus the bobbin holder and clean it. it is worth a try....

check the video hope i will help you

How to Troubleshoot Bobbin Problems Sewing Machine

Hi, sounds to me like you haven't refitted the bobbin correctly

the bobbin case does not move, just the bobbin.. if the machine is still under warrenty, I would take it back & get another sewing machine,, and probably not from them

Can you get the bobbin out of the bobbin holder? unplug the machine, then remove the needle plate, needle and pressure foot. Now can you get the bobbin out? It is possible that the bobbin holder has moved in the rotary hook, they can jump sometimes as held in by a magnet.

Check out your manual for instructions to remove the bobbin holder, it should show you how to take it out, and then clean under it, there is possibly thread caught in this area causing the malfunction.

You may find turning the fly wheel a little to turn the hook will help to free up the holder and get it out.

Here is image from my Janome 6500 manual, it should be similar for your MC.

So clean out the underneat of the bobbin holder, then reinsert it, and reassemble, thread and test. If this doens't sort the problem, then time to drive it to the Janome shop.

If you can hear a click then I'd say the needle is touching some part of the hook mechanics which could mean timing is out. However, it is possible that the bobbin case has just moved a little so as first trouble shooting steps, I'd suggest the following:

clean out the bobbin holder area as per manual (ie. remove the needle plate, bobbin, sewing foot and needle, take out the bobbin holder, clean the race area out, then put bobbin holder back in as per your manual, there is usually a stopper and knob or two red marks to line up. This is held by a magnet so it is possible to knock it out of place during a jam up.


Replace needle plate, bobbin, sewing foot and put in a new sharp needle, flat shank to the back and make sure it is fully up into the holder, thread up and very slowly using the needle up and down button, test sew a couple of stitches again.

If no stitch formation or you can definitely hear/see something touching then I'd say timing is out and no, its not something fixed yourself; best left to a trained technician.

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.

take out the bobbin (thread holder) beneath the sewing area. Clean that cavity with a brush or cotton/soft cloth. Refill the bobbin with new thread and put it back in the cavity. I hope it will solve your problem.

I recently fixed my wife maching with the same problem. I found that the screw had come loose that holds the linkage together that rotates the bobbin holder. I was fortunate enough to notice the screw while looking at the machine. To replace it requires taking both the front and back covers off of the frame since the bobbin holder linkage is in the rear behind the needle area. Be careful to insure that the plastic toothed "rail" that runs the bobbin holder is positioned properly or it may break off a tooth. Once I replaced the screw and put the machine back together, it picked up the thread with no problem. Hope this helps.
