I have this machine and love it... here lately the top tension is too loose and gets caught up underneath, and now the foot plate is off due to this. How do i get it back on so i get my christmas projects sewed?

Loop and nesting on bottom side is usually top thread tension too loose (no tension) but can be bobbin thread tension issue. Be sure to thread per machine instructions.

See following Singer video... testing top thread tension.

Test tension of top thread.
With needle up, presser foot up, and tension select = 4, thread machine. Then make a long slow steady pull of top thread. The thread should advance smoothly through needle eye without snagging from top spool. Now lower foot and make another long slow steady pull of thread. Again it should advance smoothly through the needle eye. Note difference no tension (foot up) and selected tension (foot down).


If no difference in foot up/down tension then something wrong with the tension selector or not threaded properly, consult machine manual.


You can do a similar test of bobbin thread tension. Make a slow steady pull of bobbin thread. It should advance smoothly from bobbin with tension similar to top thread with tension =4. If bobbin tension is similar to top thread foot up, then likely bobbin thread has escaped bobbin tension spring... reload bobbin per machine instructions.

Your top tension may actually be too tight! Try loosening it a bit instead. And check that the bobbin is correctly threaded and your needle in good condition.

Check bobbin case for loose threads in spring area that could be causing bobbin not to hold enough tension on bobbin thread. You can check bobbin case tension by using your needle plate. Holding bobbin case in your hand, insert a bobbin and thread it through the spring as usual. On the end of the bobbin thread, tie your needle plate to the thread. Hold case in your hand side ways so that thread travels downward with needle plate and thread trails downward across the case. The case should be perpendicular to the table top or floor. The weight of the needle plate should be so that the thread does not travel down unless the bobbin case is shaken slightly. The thread should then travel down slowly but stop once you hold case steady. If this is ok, check top tension. Turn on the machine. Lower the presser foot. With needle threaded, pull the thread the needle. You should feel some resistance. If there is none. Raise the presser foot and brush out any loose threads that might be caught in the upper tension disks. Many times, loose threads can get caught here that will keep disks from closing completely.

Hope this helps. Good luck.

Check tension levels of both upper tension unit and bobbin case.
With machine threaded, pull the bobbin thread. There should be some tension/resistence. Lower the presser foot. Pull on the top thread. Again you should feel some tension/resistence. If you don't feel any, raise presser foot and test upper thread again. If no difference, it is an issue with the upper tension disks. Brush out any loose threads that might have gotten caught in the upper tension disks which is causing the disks not to close. If there is no difference with presser foot up or down and no threads in tension unit, the tension unit will probably need to be replaced. You should have the machine serviced at the local authorized husqvarna viking dealer. You can find the nearest dealer at the husqvarna viking website - http://www.husqvarnaviking.com/us

Do you mean the stitching on the top of the work was loose? If so, you should check the bobbin tension. Make sure you have the thread pulled under the tension plate or spring on the bobbin case. Tension should be just enough that you can suspend the bobbin in the case by the thread (think yo-yo). Upper tension should be tighter than lower. Make sure you put the presser foot down.

no, more likely your top tension is too loose causing the loops on the underside of your fabric, loops on top would be bobbin too loose. raise presser foot and rethread top thdead pulling thread into tension fully. set top tension dial to 5 and test sew. if still looping underneath try tightening top tension by turning dial up to 6. but usually top tension should only need minor adjustment tweeks. you can test top tension by lowering pressure foot to engage tension and holding thread just above needle thread guide, pulling thread downwards . there should be resistence on it to your pull. if you cant feel any then tension device may be faulty, and require service.

Lift foot. Remove two screws attaching metal plate to machine. Put screws on the sticky side a a piece of tape for temporary storage. Remove knot built by sewing without material in machine or extremely loose upper tension.

Thread jams underneath usually are caused by top thread tension issues. Things to check:
top tension discs are clean and no thread traces caught in there, tension is set to medium number usually 4 or 5 and that the top thread is running freely from the thread spool, correctly thread through the tension discs, and down to the needle. Lower the pressure foot and pull the thread from just above the needle; it should feel firm resistance if under tension correctly.

As you've had a good jam up, good idea to now remove the bobbin, needle plate and bobbin holder (refer to your manual if you have never done this before) and clean out the hook area well, look for any fine thread remants and brush out any lint etc. Oil the rotary hook area as per your manual. Now reassemble, and rethread everything again checking that the bobbin thread is clicked into the tension spring and that the top thread is through the tension discs correctly.

Also, pop in a new needle, flat shank to the back, then try again.

Good luck with your machine.

When the thread is bunched up underneath, the problem is often in the top tension. The top thread is pulled through to the bottom but because there is no tension, it isn't pulled back up correctly, creating large loops underneath.

Try making sure that the thread is lying correctly between the tension disks (you can just see them inside the machine on the downward thread path). Lifting the presser foot lever (behind the machine) opens up the disks and lets the thread slide between them more easily. They will close again when you put the presser foot down to sew. Make sure you always thread the machine with the presser foot lever up and tension disks open to avoid this problem in future.

If the thread is running correctly between the tension disks, just check that you that there's no fluff caught in there, holding them open. Give it a blow, or run a folded pice of fabric through there.

Try rethreading the top of the machine making sure you get it thru the tension wheel correctly.. General rule of thumb.
If it loops on the bottom, the problem in on the top.. Loops on the top, problem is with the bobbin.
