Question about Singer 6038 Mechanical Sewing Machine

3 Answers

Bobbin problems I was sewing with no problems. Moved on to next piece and now the bottom threads are loose, bunch up and clog the bobbin. The needle seems to be hitting the bobbin incorrectly causing the needle to hit and stop. I have removed the plate and cleaned the bobbin areas and feed dogs, but it hasn't helped. The manual has been no help and you cannot tell anything from the manual pictures. I have the same problem. Machine was working fine and then all of a sudden the needle seems like it's hitting the bobbin in the wrong place or something. If it doesn't get bunched up, then there is absolutely no tension in the thread.

    I own a Singer 6038 and I am having the exact same problem. I'm at a standstill on some projects I need to finish and cannot get past this problem. I too have cleaned everything, checked everything, manual is of basically no use. My top stitches are lovely but the bottom stitching is wretched and bunched so badly I didn't know I had so much thread! Please, what to do??? Should I replace the bobbin case? Diane

    I know exactly what you mean, this is so irritating! The top stitch is beautiful while the bottom is bunched up. Sometimes re-threading helps, but most recently nothing is helping...

    I have the exact same problem. I have tried everything I can think of and still I have a tangled loose mess of thread on the bottome side of the fabric!! Nothing seems to correct this and I am beyond frustrated! My Mom's old 1962 Singer still works better than this and has never had a glitch!! Why don't new products last like the old ones!?

Any time you have looping on the bottom, it is almost always related to the upper tension and not anything in the bobbin area.
A good way to troubleshoot this is to turn the machine off, blow out the upper tension disk assemblies with canned air, (the machine needs to be off because most canned air uses butane as a propellant. Butane + electricity = bad;) replace your needle, and rethread your machine. Once you've threaded it to the point where you're about to put the thread through the needle, "floss" the thread forward and backward to ensure that the thread seats correctly into the tension assemblies.
Set your tension to around 4.5 for most applications, and drop your presser foot. Give the thread a gentle tug to see if the tensions have engaged the thread, then thread the needle.

If doing this does not address the problem, you probably need to have your tensions professionally calibrated. This is also true if the needle is in fact hitting something in the bobbin area. This is usually caused by the machine's timing being out of alignment, which is not something that can be fixed at home.

Good luck,

I had the bunching up problem too.... I didn't have the thread properly position through the tension plates. I had it around the outer white dial; which i found out by trial and error is not where the thread was supposed to go.

Be sure you are using a Class 66 bobbin for this Singer machine. Using another style bobbin can cause tension problems and thread looping/bunching.

SOURCE: Thread is bunching underneath fabric

Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.

Refer to your machine for cleaning the bobbin area.

You will need to clean this area often as lint and thread snips can build up can cause the bobbin feed to malfunction.

If this continues after you have cleaned the machine, the timing may need to be adjusted by a sewing machine tech.

Why does bobbin thread keep snagging?


increase the needle thread tension up a bit as it is too loose to pull the bobbin thread up properly
keep adjusting until both threads are at the middle of the materials being sewn

Bobbin thread bunching up on bottom side od material while sewinginto a mess, while top thread fine. HOW DO I fix this, please.


Hi, this is a lack of lower tension. Check to make sure your bobbin is seated correctly and that you have used the correct thread path. Check the tension by drawing some thread from the bobbin with your hand, if it reels off too easily, the tension hook for the bobbin is too loose, tighten it down a tiny bit with a small screw driver and try again. If the bobbin tension is normal, than the problem may be your upper tension, if it is too tight it can cause your bobbin to snarl. If a tension adjustment does not fix the problem, you may need to seek a specialist.

Thread is bunching up in bottom.


It sounds like you have no tension on the bottom bobbin reel. Did you check your tension on the bobbin reel. The tension must be right on both sides. When pulling on the cotton when the reel is in its bobbin case you need to feel a little resistance. Adjust the tiny srew on the bobbin case to tighten the reel to avoid it to turn in the casing.

The thread on the bottom bunches up all down at the bottom than bunches up


Usually problems like this are caused by improper bobbin winding and installation, incorrect tension, the wrong needle for project, or simply not grasping the threads and gently pulling them backwards when you start a seam.

1. Make sure you are threading the machine correctly.
2. Check your tension.
3. Check the bobbin, make sure it's wound properly and that you don't have the bobbin in upside down.
4. Check for bits of fluff and thread in the bobbin race area.
5. Change your needle, they wear out, get bent, dull... etc. You should have several different types on hand at all times.
6. Grasp both the threads gently and pull slightly backwards when you begin a seam. this will assure that your bobbin thread doesn't get all bunched up under the fabric.
7. Always test tension, needles etc., on a scrap piece of fabric before you begin sewing your project.

When sowing the thread bunches up in a ball. The inner rotary make noise, how to correct problem?


first change the needle
clean under the needle plate where the feed dogs are for lint
also clean the bobbin area for lint or loose threads
rethread the machine-top thread & bobbin

some time the top thread can come off some thread take up levers--that should be watched when sewing

check to make sure the bobbin is always wound correctly--and incorrect wound bobbin can cause sewing problems

The thread is loose on the bobbin end when sewing...the top is fine, but the bottom is so loose and bunches up into a mess.


Make certain the bobbin is inserted correctly into the bobbin case. If it is, be certain the bobbin is wound tight. A bad wind will cause the loose threads you mentioned. If both of those options are all right, check your upper tension. Generally, it should be set at 3. Also, make sure the needle is inserted correctly...the groove on the face of the needle should be facing the front of the machine (it is actually a thread guide). And last, has the bobbin case been removed and cleaned? If not, this could lead to "messy bobbin threads." I hope one of these suggestions is THE one for your problem. Good luck!

Sewing a bunch of thread from the bottom, this stops the machine from actually sewing


Yes, it does. There are a couple of reasons the bobbin thread could be bunching up on the underside of the fabric. It could simply be that the machine needs cleaning. Take the bobbin assembly out, brush all the old lint out as best you can, reoil the machine once it's all clean, and make sure there aren't any little bits of thread caught in the bobbin assembly. Rethread the machine (carefully) and change the needle. This solves the problem usually--especially if the machine was sewing along fine and the problem develops suddenly. '
The other thing to check is your tension. It could be that the top tension is too loose. But different color thread in the top and in the bobbin, stitch a few inches (be sure to held the top and bobbin thread ends behind your needle as you start to stitch) and check. WIth the pressure foot down, adjust the tension, and stitch again. Keep stitching, checking, and adjusting until you see little if any bobbin thread on the top or top thread on the bobbin.
Another thing to reminder: use the appropriate thread and needle for the fabric you're sewing.
Let me know if this works, ok?
