Question about Sewing Machines
I have a janome 3160 qdc. The bobbin case keeps popping up. I have the JANOME BOBBINS IN IT AND IT STILL DOES IT. iS THERE A NEW FIX FOR IT. I have had this machine for 4 years and have had it in the repair shop several times. The technican did a repair that Janome sent several years age. It is still doing it. He said there was a new fix for it is that true. Also how do I put it back in when it comes out.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

You need to ask Janome these questions, rather than Fixya I think. The plastic bobbin in the plastic bobbin holder does make a little bit of noise but I don't find it problematic.

Providing you are using "Janome" plastic bobbins and are putting them in rotating the right way, as per the little image on the clear cover, there is no reason that the thread cutter should be dislodging the bobbin. When I use the thread cutter, my bobbin turns as thread is drawn off it, but it doesn't move upwards.
Sounds like you have already replaced the black plastic bobbin holder, is that what you mean by "Shuttle"??
My 6500 has had 2 replacement bobbin holders as I keep striking it with the needle during jam ups, which caused plastic burrs on it. On the last service the technician added a little piece that is a janome "after sale replacement" part. It is slightly longer than the standard part, and is a little metal bit on the left hand side of the rotary hook area which seems to be working at holding the bobbin holder in place better. Haven't had a big jam up since he fitted it. But before this, I would dislodge the bobbin holder with a small jam, and then it would just jam and jam until I removed the needle plate with the screwdriver, removed the bobbin and bobbin holder, cleaned out all the thread fragments, then replaced the bobbin holder back into the correct position lining up the two red arrows. Then replaced the needle plate and rethreaded. I learnt to modify my sewing expectations and not try to sew really thick seams as this will just dislodge the bobbin holder again. Jeans hems were always my problem seam, I use a "Seam Jumper" now to handle going from thin to thick seam, and so far, so good.
So I would suggest you ring Janome in Akld and talk to their technical advisor a bit, describing your problem. They may suggest sending it to them for a check out to establish what is going wrong.
If you have trouble describing the issue to then you could always film it with a digital camera and send the file to them.
My only other thought is how you wind the bobbins. It is really important to wind the bobbin smoothly and evenly top and bottom, my 6500 will wind all in the middle if I let it just run, so I always wind carefully and give the thread a nudge with my fingertip to ensure it fills evening top, middle and bottom. But it sounds like you are an experienced sewer and know this already.
I'd say ring Janome and have a chat, I find if you keep your approach friendly and neutral rather than "I've never got on with this machine" that you may get some help from them at resolving this issue.

Has the bobbin case dislodged and moved? there should be two red marks one on the bobbin case and one on the outer holder, are they lining up? Sometimes as these cases are held by a magnet, they will get dislodged and move slightly, especially in a jam up.
Take out the bobbin case and clean under it, then replace it matching up the red marks.
If the bobbin case has actaully been struck by the needle during a dislodgement, it may well pierce the bobbin case plastic, look for burring or marks on the outer flange area. If this has occured, the thread may catch on the burr as it comes over the bobbin and jam again.
You can buy a new bobbin case if yours is damaged or maybe just file the burring with an emery board (remove it from the machine first of course).
Lastly, check your needle hasn't been bent, burred, or put in backwards, any of these can prevent a stitch from forming.
If all the above fails, then it is possible that the timing has been knocked out and you will need to get it serviced by a technician.
