Question about Husqvarna Sewing Machines

1 Answer

I have a HV Designer SE and the top thread loops BIG (+1" loops) on the bottom and jams up. It looks like pretty normal stitches on the top, but it isn't good underneath. The loops get tangled up and the machine can't go any further. I have taken the machine in a total of five times with this problem and nothing they do seems to help. I asked if it could be bad tension discs and was told they have never seen them go bad, so the repair man thinks it could possibly be the motherboard, but he doesn't really know. My screen and everything else works perfectly. The only things is this looping/tension thing. Do you have any ideas?

    The needle and top thread go through the fabric to form a stitch with the bobbin thread. A good stitch balances the threads so that they meet in the middle of your fabric before moving forward and taking another stitch. When my machine decides to act up, instead of the top and bobbin threads tightening in the middle of my fabrics, my top thread is loose and long on the bottom--the depth the needle carried it down. It doesn't get pulled back up to form a stitch in the MIDDLE of the fabric. Does that explain what is happening better so someone can shed some light on this problem?

Try these suggestions
new needle
check to make sure that the top thread has not come off the thread take up lever
make sure the bobbin is turned the right way in the bobbin case
the machine could have a timing problem
I suggest taking the machine tp a different repair shop next time,
when you take the machine in 5 times and it's got the same problem, it's time for a different repair shop..

SOURCE: Loose stitching underneath. HOW CAN I FIX!!!!

I'm **t sure what you mean by freehand stitching........do you get a good even stitch with zig zag, this is the most important first test ?

Ensure that all is clean and free of lint jams....**w for tension troubleshooting .......

This solution is for tension problems...if you can**t form any sort of stitch, the issue is quite different, so please let me k**w if you need a different problem solved.....

It is quite long, but just work through each section in order.
The "k**tting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your
projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and **t to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with
a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to
disengage tension plates).... do **t gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would **t recommend fiddling with bobbin tension without good reason, it may end up with missing small *****s and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (**t soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is ** lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension ***** in the middle of the metalwork....

4c76dc1.jpg ...the other ***** at one end is holding it all together, so beware....it is **t a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's ** trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension ***** very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it can**t be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....** case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (a**ther reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

SOURCE: Loose stitching underneath. HOW CAN I FIX!!!!

Sounds as though you may have a burr or rough spot on the hook where the bobbin inserts. Run your finger along the edge of the hook to see if there are any rough spots.I'm sure you're going to find at least one from the time you broke the needle.Once you locate it, remove it with an emery stick or small sharpening stone. Polish it so that it is smooth. Should work okay.

SOURCE: tension on stitches

Loose bottom stitches mean the UPPER tension has a problem. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it does not work this way( the tension stays loose) you will need to set the tension to Zero, open the discs with a small screwdriver and remove the lint or thread which is stuck in there.

Try oiling the hook if you haven't recently.
Check you needle plate and hook for damage, they may need to be buffed or sanded smooth.
Check your upper tension discs for lint and double check your upper thread path (proper threading).
There are other things like hook timing, needle clearance or broken check spring that may be wrong but you need a technician for those things.
best of luck!

SOURCE: Top thread stitches correctly but bottom thread loops.

FYI---- Loops on the bottom-- problem is in the threading..

The cotton on my bernina 801 keeps jamming


Loops on bottom indicate a top thread tension problem.

Make sure needle is the correct size and not bent or broken
Make sure it is threaded properly with the lever UP.

Do a test stitch.

If it still loops below... tighten the top tension and do another test stitch... keep doing this until the stitch is balanced.

BTW... always grasp and hold both threads when starting a seam.

Loose bottom stitch on brother se 350


Hi, general rule of thumb:: loops on the top, problem on the bottom.. Loops on the bottom, problem is on the top.. When threading your machine, stop just before you thread your needle, put the presser foot down. Try pulling the thread. If it pulls easily, the thread is not thru the tension wheel right. If it pulls hard, you got it right.

Bottom thread is very very loose during stitching, looped up


Looping on bottom:
Great description, that helps a lot. Big loops are actually easier to solve usually. 1st know this: Loops on bottom means the top is too loose or the bottom is too tight. With loops that big its probably the top is too loose. 1st look in tension disks, there is likely a chunk of thread in there. A toothpick is handy to dig it out (the flat kind) 2nd make sure that the thread is getting between the disks when threaded. 3rd Make sure the thread is in the take up lever (the thing that moves up and down in front and not the needle bar or any part of the needle bar.) If neither, then the bobbin case could have a burr on it and the thread is hanging on that burr. Also the bobbin case may be in wrong. I hope this helps

Free motion quilting Viking Designer 1


I had the same dissatisfaction when I switched from the 1+ to the Designer 1. After some trials I am now happy. You need the springy free motion foot. Part #413 03 76-45. You take off the white shank and screw it on with the metal bar over the needle hook. In the set menu turn the SensorQ on, the free motion on, select stitch 1 from menu V and drop the feed dogs. It also makes a big difference to use the straight stitch throat plate which just has a small hole for the needle to go through. One other hint is that I often have to reduce my needle tension 3 or 4 steps. Hope it works for you.

Big loops on bottom stitch


You have no top tension. Rethread the top of the machine. Make shure you raise the presserfoot before threading.

Free Motion Sewing - Jams


The Designer 1 usually has a very nice free motion stitch using the V1 stitch. It should pull only slightly to the rear so that no bobbin thread shows while doing free motion embroidery. Upper tension may be increased for balanced stitch when stippling.
If your machine doesn't sew with the regular stitches with the teeth up, and it's properly threaded, the thread must be dragging on the bobbin case somewhere. First get the machine sewing a straight line, then try V1 again.

Thread tension problem when sewing on heavy fabrics


Sometimes when I need to use heavy thread for top stitching to reinforce a seam that has come undone, I will use the heavy thread on the top and regular thread on the bottom. I haven't tried it the other way around for hemming but I would think it would work. I do not currently have a Bernina.

Satin Stitch Problems - Designer SE (similar to the Designer 1)


It sounds like to me you might have some thread stuck in the tension assembly. Possibly some thread "snubs". Also there is an internal service program on this machine that could also solve that problem. That is why you need to take it to a qualified Husqvarna service center to be fixed by a qualified technician.
