Question about PfaFF Sewing Machines

1 Answer

I have the upgraded 2140. I am doing satin stitching. I was having tension issues and finally got it working for me. I changed thread color and now the top thread is not connecting with the bobbin. It sews a few stitches then stops with the error message and a ball of thread on the under side of the fabric. I have tried different settings and switched to a straight stitch and still have the same problem. This machine is new to me so I am still learning how to use it. Any help will be appreciated.

It sounds like the problem is actually with the needle thread, remove the spool from the machine, raise the preser foot to the up postiton and the rethread the machine.
Good Luck!

I have a Bernina 145 S activa and I can't get my satin stitch to work , it brings the bobbin thread to the top , what can I do ?


Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.

It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)

I have a brand new Juki MO-50e and the threads are loose on the back of the fabric, how do I fix this?


  1. . re-thread your machine with a rainbow of colors. (important that you remove the existing threads if you are not sure it is threaded properly.) make sure you are lifting the presser foot while rethreading.
  2. Sew a good 6 inches.
  3. Look to see which threads are the offenders and tighten the co-responding tension knobs a little.
  4. Sew another 6 inches. Examine the result. Adjust tension again if needed.
  5. Work this way until you have the stitch balanced.
  6. Finally when your stitches are perfect. clip the threads at the spools in back. And tie on the coordinating colored thread for your fabric.
Get used to this procedure since it is common to have to adjust tensions when you change fabric. Good luck!

Embroidery not working correctly


Well, before I did all that (which may be necessary), I would take a piece of UNWAXED dental floss or hand embroidery floss and floss between the tension disks. You mentioned that you were suddenly breaking threads; there may be lint or loose threads or both seated between the disks, preventing the thread from seating properly. Then,
I would take the embroidery unit off and try to do some sewing with it, to see what results I got. If you can catch and bring the bobbin thread to the top with the top thread, I am doubtful that your timing is off. Sew a line of both straight stitch and zigzag stitches, and see if the stitches are balanced. If not, you may have a bobbin tension issue, and if so, most bobbin cases can be adjusted.

I think you'll find, though, that things will improve considerably when you have cleaned out the upper thread path and tension disks. Make sure when you do that, that your foot is raised, so that the disks are spread. Oh, a drop of sewing machine oil wouldn't hurt either--generally you should put a drop of oil for every 5 hours of embroidery.

Please get back to us to let us know!

Upper thread keeps breaking


Symptoms like this are typically tension or threading problems.
Grab some dental floss (unwaxed) completely remove the top thread. Lift the foot. Run your floss between any tension discs.

Get out your manual and make sure you thread it properly. Have the proper retention disc on the thread spindle if your machine has one. Make sure the thread is unspooling the correct way. Thread the machine with the foot up always. ...

Test sew on scrap. still breaking? Change the needle (make sure it's the right needle for the project.) Test sew. Finally check your tension and stitch length. Thicker materials typically need longer stitches. Loosen the tension a little at a time. testing between changes.

If none of those things work... check your needle throat plate and foot. There could be a burr causing the problem.

How do you adjust the tension on a Bernina 180


There are two tension adjustments, which should be done with a proper set of weight gauges - top and bottom thread tension should be carefully balanced to get the best stitch formation. It is best that you assume the top tension is correct and adjust the bobbin tension to match. Load the bobbin with thread of one colour and put a spool of the same thread but a different colour on the top. Thread-up the machine, load the bobbin and sew-off a satin-stitch on max width zig-zag. In this configuration, there should be a very small 'bead' of the top thread showing along each side of the satin-stitch on the underside of the material. If there's excessive top showing, the bobbin tension is too high and if none, the bobbin tension is too low. To adjust the tension, remove the bobbin case and you will see a spring around the edge with two screws through it. One of the screws holds the spring in place and the other adjusts the tension - this is furthest from the edge of the spring and is in a small 'cup' in the spring itself. To reduce tension, turn the screw VERY SLIGHTLY anticlockwise and to increase it turn it clockwise. Make very slight adjustments and re-check sewing-off the satin-stitch every time until you get the required thin line of top showing down each side of the stitch on the underside. Ideally this should be done with Mettler Metrosene thread, but as we're just balancing against the top tension, it shouldn't matter too much provided you use a good thread top and bottom.

I am having trouble trying to overlock satin. the machine will overlock cotton fine but when I change to satin it seems to miss stitches


Have you changed the needle(s) recently in your overlocker? I would put in a new sharp size 70 for satin, turn down the stitch length a fraction, put the blade about middle of its range, thread tensions all to 5 and test serge. Then adjust the two looper tensions until you get the thread wrapping around the smoothly but not bunching up the satin within the stitch. Also put your differential to zero for a start and see how the stitching looks.

It is easy to forget to change the needles in the overlocker because it is usually a bit of a fiddle but they will go dull. And remember to just loosen off the needle screw a little, enough to remove the old and insert the new, don't turn it all the way out as they come out and there is often a little ballbearing up in the needle housing that can drop out and get lost with some models.

Also most sergers the two needles sit at different heights so make sure you've got them both fully up into the housing and sitting right, tweezers are a big help with this, I usually pop the needles into the housing, then balance the needle points on the screwdriver blade and lift it right up until it is all the way up, then hold firmly with the tweezer and do up the needle enough to hold it. Then repeat with the 2nd needle, then go back and recheck the first one until they are both spot on. Then manually turn through one stitching sequence to ensure that the needles are not touching the loopers, if you hear any touch, go back and recheck the needle placement again.

If you are just neatening single layer edges I would just use a 3 thread on satin and take out the left needle so it doesn't leave holes. If you are seaming two layers, then go to four thread (both needles) but you may need to use a bit of differential if the seam is puckering a bit.

If you find that changing the needle makes no difference at all, and stitches are still not forming correctly then it is possible that the timing is out a bit and the machine would need a service to sort this out. Hope this helps you out.

There is one way out. Give the sewing m/c a thorough servicing job, Clear all the pieces of cloth/fabric/threads, etc Remove the bobbin and load afresh. Clear out the toothed sliders which pulls the cloth while stitching. the thread being used for stitching passes a sort of loop, the tension being controlled by how much the pressure the spring can exert such that depending on the material being stitched. Specially after stitching satin, which is tricky material to stitch in a sewing m/c since the cloth is slippery. Also clear sewing jam and the metal teeth like rack which pushes the cloth for the next stitch to start.

When appliqueing in stitch 11 the thread kees looping...


I believe stitch 11 is a zig zag so you are probably decreasing the length to get a satin stitch. You will get a better satin stitch if you select it directly. I think that it is about 29. The machine forms the satin stitch differently than the zig zag and it should look better. If you still get loops on top, you may need to have a qualified technician check the needle to hook clearance. If this distance is too great, the machine skips stitches and you will form loops. Several other adjustments may be needed to get a perfect stitch and a qualified Husqvarna technician should be able to take care of this problem for you.

Bobbin tension


Bobbin Tension Adjustment:

1. Do you have a genuine Bernina bobbin casing and not an Oriental copy? If yes, proceed as follows:
2. To set the bobbin tension, wind a genuine Bernina bobbin with Metrosene thread, type 1161 white thread as your "gaging thread". Load the bobbin case so that the bobbin turns CW. Attach the bobbin case to the hook body from the machine. Wind a couple of revolutions of thread around your index finger with the assembled bobbin case and hook body dangling about 6" to 12" below your finger. Gently and rapidly move your finger back and forth in a "sideways" motion about 1/4" to create a gentle vibration on the bobbin assembly. (Do not shake the bobbin assembly up and down). When the tension is right, the bobbin assembly should fall slowly and as you stop the movement, the assembly should stop.
The adjustment is found on the small screw, holding the flat tension spring against the bobbin case. If the tension is too tight, one must loosen the screw (past) the desired location and always make the adjustment by tightening to the correct position.

There are other checks for tension imbalance and associated problems on the bobbin case that I won't go into here. For further information I can help you later on.

Top Tension Adjustment:

1. The top tension rarely changes and can be depended on throughout the life of that machine providing that tension assembly is maintained occasionally. This can be done by blowing out the tension disks with the presser bar lever in the up position. One can also drag or pull a piece of sized percale or muslin through the disks with the presser bar lever in a down position. Perhaps both methods can be employed.
2. Load the top of the machine with Metrosene 1161 thread in a dissimilar color. I prefer to use a pastel color so as not to create an optical illusion of imbalanced tension.
3. Sew a satin stitch (.25 on the Nova 900) in sized cotton muslin with a thin piece of paper between two plys of fabric. The width should not exceed 4.5mm (standard width on the 900 Nova), however the newer machines have wider stitch widths so one must adjust as specified. The result will be a slight amount of top thread in symmetric lines on both the right and left sides of the satin stitch.

Typically, the top tension will not need adjusting. If the Nova 900 needs adjustment, please ask for additional help.
