You should have the upper thread sensor checked out by a qualified Husqvarna technician. The check spring operates the sensor. If the check spring is sticking for some reason, it will cause this to happen. It may be as simple as removing lint from the sensor area or a little more involved as in changing the check spring completely. Either can be done without removing the front cover.
I don't recommend trying to remove the tension assembly cover yourself. If you break it, it's an expensive piece to have replaced. If I break it, it is an expensive piece for me to replace. See the difference?

I just got a new singer 4423. it stitches just fine for a while, then the top thread becomes a loopy knot underneath, snags, then returns to regular stitch. my old 4423 did the same but not as bad.


A couple of things you might want to check. Did you know that when you thread ANY sewing machine, your MUST be raised? That is the only time the upper tension disks are spread to accept the thread when you thread the machine. If you don't do that, there's no tension on the upper thread, and that's the kind of thing that happens.

There are are other causes for that. Run you finger over the needle plate to see if there are any rough spots that can catch the thread, and do the same thing on the bobbin case. If there are, use an Emory board to file them smooth.

first ,re thread the upper bobbin, check the needle to match the fabric and the lower bobbin thread should be the same like the upper thread. If it dose not work, clean the discs tension for the upper thread.

Why does my thread knot on the back when stitching in place?


Several things to try:
Pull thread tails (both bobbin thread and upper thread) straight back and when you lower the presser foot, make sure they are held down straight back. This may or may not be enough to solve the problem, but it is simple to try, and often works. You might want to hold the thread tails while you start sewing.
Use a starter--folded piece of fabric scrap about an inch long--and begin sewing oink middle of starter. Push the fabric you want to see right up to the starter and keep sewing from the starter right onto your project without lifting the presser foot or cutting the thread. When you finish sewing, cut the little piece of thread between the starter and your project.
Before lowering presser foot, use wheel to lower your needle once and then pull up bobbin thread to top surface of your project. Then hold both bobbin and upper thread tails, lower your presser foot, and begin sewing. Release the thread tails after a few stitches.
Hope this helps. Those nasty "thread nests" are a real pain.

When sewing, the top stitch and thread is fine. when you look under it is a huge mess of upper thread. I have cleaned shuttle, fixed the bobbin, replaced bobbin and upper thread. A number of times.


Recheck the tension on the top thread. Test it before you put it through the needle to see if there's any tension. It should pull but with some resistance. Also check the needle and make sure it is the right type for the fabric and not bent etc.

Looping on the underside of the stitch is from the upper thread, usually tension problem. But do check the bobbin tension and make sure it isn't too tight, though that's not usually the problem you're describing. The two tensions need to work together in order to get a nice, flat (not puckered or loopy) stitch.

One last thing you might check too, though again this wouldn't typically be the problem - is the dogfeed moving the material along under the presser foot correctly?

Most of the time the problem you're describing is due to not enough tension on the upper thread.

I have a bernina overlocker and whenever I use it the lower looper (marked in red) thread breaks. How can I fix this? It was serviced yesterday and when other people used it before me it worked fine!


Then it's one of two things. First try setting your lower looper tension on 3 and see if that works. If not set it back on 4 and cut ALL your threads and re-thread the machine STARTING with the UPPER looper, then the lower looper, then the right needle, last the left needle if you're sewing a 4 thread overlock stitch. Make sure the threads aren't twisted in the thread guide. Make sure the lower looper thread is OVER the elbow on the upper looper and over the upper looper thread. Let me know if this works. We'll work until we get it fixed!

Mine is doing the same thing. It's pulling the thread up from the bobbin and making a huge knot. Any suggestions. I've done all the above checks. Brand new needle, tension is on embroidery, threaded properly and no lint in bobbin compartment.

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!

Instructions for threading Baby lock eclipse BLE1LX for 2 thread sergering


I have just learned this :)
Either needle thread may be engaged for 2-thread serging.
1. Open the front cover and cutting blade cover, cut the upper looper thread just above the threading guide ( this is plate that has two holes for the threads) Raise the presser foot and pull out the clipped thread from under the foot. Remove upper thread from the machine (or you can leave the cone thread on, it doesn't matter).
2. Rotate the handwheel to bring the upper looper to its lowest position.
3. Rotate the subsidiary looper up and to the left, then slip the end into the upper looper thread eye from backside.(this sounds complicated, yes? but it is very simple : the looper has a counter part that is spring-locked to move from left to right and right to left. This is the little claw-looking part of the looper that when in the postion to serg with four threads is to the right side of the looper. It looks like a scorpion's tale. If you can't figure which part it is, use your finger to probe the looper and you'll feel it give a little. This part needs to be moved to the left - it will not slide over, but swing up and over and down, like an arch. Then, where the thread comes out of the looper is where you want the little claw-like part to hook into.)
4. Close the covers. Decrease the needel tension - this depends on what the stitch length is. Stitch length: 2-3, stitch width: 3.0 = L needle n/a, R needle 1; upper looper n/a, lower looper 5
stitch length: 2-3, stitch width: 5.0 = L needle 0, R needle n/a, upper looper n/a, lower looper 3.5

Those are for a flatlock stitch - for a 2-thread rolled edge :
Stitch length: 0.5, stitch width: M = L needle n/a, R needle 4.5, upper looper n/a, lower looper 3.5
Stitch lenght: 1.0, stitch width: M = L needle n/a, R needle 4, upper lopper n/a, lower looper 3.0

This error indictaes that the upper thread is broken. If it is not the sensor is telling the computer the thread is broken. Try tightening the upper thread tension some and rethread the upper thread.
