Bernina overlocker 203 locking thread is not sewing on fabric

The overlocker/surger has been threaded correctly, as far as we know, but the thread locking is not sewing on the fabric. IT is off the material. Do you have any ideas or suggestions concerning this?

You need to adjust the tension for your threads. Use scraps to test sew as you adjust the individual threads to bring them into proper balance. Your manual will tell you how to do this.

It is not the tension, leave the tension alone for now. It is the knife settings, move the lower blade a bit to the right and try it, keep doing that until the stitch is on correct place on the material.... Your manual will tell you how to do this.

Reverse side of overlocked material looks like lace how do I correct


Sounds like the tensions are loose. BUT, before changing the tensions do this:

Remove all the thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning. Thread each one in the proper order. (Threading out of order will cause problems!)
When threading from the thread tree down through each tensioner, give each thread an extra little tug to make sure it is seated completely.

Re-test your machine and either tighten or loosen the thread tensions so the threads meet in the middle of the fabric. If you are unfamiliar with a serger, using 4 different colors of thread will help you diagnose which thread tension is the problem.

I am trying to teach myself to sew.... what is a serge stitch an how do I set my brother sewing machine to do it?


A serger (overlocker) is not a sewing machine. If you look at the inside seams of a purchased t-shirt, you will usually find a serge stitch that was created using a serger (overlocker). A serger/overlocker usually uses 3 or 4 threads to create that stitch. It also trims the fabric at the same time it finishes the fabric edge. The serge stitch is a chain stitch that, if you pull a particular thread, the entire stitch will come undone.

Your sewing machine is not able to create that same stitch. Your sewing machine may have what is called an "overlock" stitch, but it will use only 2 threads (the top and bobbin) to create that stitch. You would have to consult your owner's manual to see if it can make an overlock stitch.

Hi. I have a new overlocker. Fabric got jammed ,got it out but machine now jams at half turn . Could some fabric still be under feed dogs ? How to get it out ?


Hello Jenny hornsey

This may sound traumatic, but there is no easy way to pin point where the tie-up is located. So proceed as follows.
Cut all the threads as they come off the antennas.

Open the front cover and pull-out all the threads by pulling them straight toward the back. If they do not come easily, try moving the hand wheel back and forth by a 1/4 revolution .. this is like a rocking motion. If still not budging, start cutting back the threads and removing them in sections until all the threads are cleared. If this step is still challenging; check that there is no residual fabric or threads still wrapped around the loopers or other part/s of the serger. If so cut them out bit by bit until everything below is cleared.

Great. Now check for threads wrapped and/or jammed anywhere above.

Since the overlocker jammed, it is possible that the needles were bent. This will continue to cause issues in stitch formation. So just to make sure; change the needle/s. Make sure that the correct needle type is being used. Every overlocker is engineered to be used with a specific needle type. The needle type will be specified in the manual and will also appear on the needle package. If the needle types are not the same, do not use those needles.

Re-thread the overlocker and stitch test on a piece of fabric before pressing down on the foot control.

This should get the overlocker back on track and you back to overlocking.

Please let me know how this works out for you.

Happy overlocking

I need help in good tension for rolled hem in empisal 606D overlocker


Your owner's manual should have instructions for rolled hem settings. My Bernina manual has a the following settings:
Medium weight fabric
80/12 Universal needle
3 cones serger thread
Upper looper 3-5
Lower looper 7-9
Left needle (no thread)
Right needle 3-5
Stitch length 1-1.5
Cutting width 2-3
Differential feed N

Can use woolly thread in the upper looper, but the tension may need to be loosened since the woolly nylon thread will stretch.

Bernina 335 serger won't sew/overlock. carefully rethreaded the serger but that hasn't helped.


The 335 has a two thread chain stitch (stitch type 401), and the overlock side (right needle side), is a three thread plain overlock. If you are describing the plain overlock as the problem, I would first suggest the following in re-threading:

1. Thread the upper looper
2. Thread the lower looper
3. Thread the needle last (important)

If the needle threaded, you cannot re-thread the lower looper without breaking the thread.
In order to thread the lower looper, the lower looper must pass by the needle thus picking up the needle thread. So, instead of threading the lower looper thread underneath the needle thread, the looper would be threaded on top and cannot sew without breaking the thread.
Make sure that the threads are bedded between the tension disks. Check this by stretching the thread fore and aft of the tension disks as well as visually noting that the threads are not accidentally threaded behind the disks. You can also loosen the tension disks when threading so as to allow the threads to bed deeply between the disks.
Please reply with your observations.

What are the tension numbers for a Bernina MO-203 over locker sewing machine?


Basic Tips for All
  1. Always turn the handwheel TOWARDS you (counter clockwise) as turning it in the opposite direction (away from you, clockwise) may knock the timing out requiring repair from a service center.
  2. Always be sure your presser foot is in the DOWN position before sewing. Sewing with the presser foot in the up position will cause your thread to tangle and your bobbin to jam.
  3. Change needles regularly (after 16 hours of use) as dull/weak needles can cause damage to your machine and fabric. Only use SINGER needles on your SINGER sewing machine.
  4. Always be sure you are using the correct bobbin for your machine. Class 66, Class 15 and Class 15J bobbins look very similar. However, using the incorrect bobbin class in your machine can cause damage.

2 Thread overlock


My experience one time was when I was sewing on challis and using serger thread that was not a name brand. I talked to a friend and the first 2 questions were thread I was using and fabric-

challis and less expensive thread- any fabric that is slinky and moves around is unstable- better quality thread solved my

problem- on your problem if you are using an unstable fabric

try using a solvy stabilizer and try it. Then I would find

a New Home dealer and ask them. Good luck

Is wooly nylon suitable on woven fabrics?


I dont use wooly nylon on my sewing machine, only my overlocker, as its ideal for lycra and jersey fabrics where you want some flexibility and stretch in the seam. You could probably run it in the bobbin but you may find the machine top tension won't like wooly nylon going thru it. The only time I use it on a woven is when making a rolled hem edge on the overlocker, and I use wooly on the top looper only, regular thread in needle and lower looper. Its pretty expensive thread so I use it for special tasks only.
