Hi :) How did you check the bobbin tension? The thread should come through to the top side. So let's take a check here and see what is going on.

Take the bobbin out. Take a hold of the thread and suspend the bobbin (in the case) underneath it. Still holding on to the thread let it dangle. Does it reel out to the floor or does it drop a bit with some resistance and sort of stop? If it doesn't fall to the floor with thread between it and you then there is some tension to the bobbin.

Proper bobbin tension, when doing the above, dangling the bobbin by the thread, should allow some thread to come out but not reel out. If it drops a lot then there isn't enough tension. Look for the adjustment screw and tighten it until it behaves as it should when testing. Then place the bobbin back in the machine, listen/feel for the 'click' when it's in proper place. By the way do make sure that the thread was wound evenly around the bobbin and that it was doing in the right direction when it's in the bobbin case.

Now let's look at the top thread. Totally unthread the top side and rethread it again making sure it is going through the guides and not catching/looped. After putting it through the upper tension pull on the thread and feel the resistance. Again it should pull through and not break but there should be some resistance. Now thread the needle.

Get some scrap fabric, doubled as if you're sewing a seam. Set the machine to an medium stitch length and a wide zigzag. Sew a few inches and take the material out to exam it.

The top and bottom stitching should look identical. Make sure you remember which is the top side and which is the bottom. Turn the fabric over and examine the bottom side. Do the two sides look the same? Are the stitches neat with the thread going through to the other side at the outside of each zig with no thread from the other side coming towards the middle? If one side is drawn up, puckered than the thread tension of the other side is too tight. And if one side has thread drawn through going towards the middle that opposite side tension is too loose.

Remember to think in opposites. The bottom side of the stitch is effected by the tension on top, ie through the needle. The top side is effected by the bobbin tension. Often people assume that if the underside of the stitch is loopy or loose looking the bobbin is too loose when actually it is the top side that is too loose (or the bobbin tension way too tight).

Try this and see if this will fix your problem ---- or I didn't understand your description correctly...

This is on a 5.0 pfaff sewing it will build a bird nest below the plate


Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the top tension to the midway point (may need to tweak this for your particular machine).

Remove the bobbin thread from the machine. Reinstall the bobbin in the bobbin case confirming the bobbin is turning the correct direction and the bobbin case is correctly threaded.

Pull the bobbin thread up to the top of the fabric and gently hold both thread tails in your left hand when slowly taking the first couple of stitches.

My pfaff 1475cd is missing in the bobbin stitch very slack tried a few things even got a new bobbin case machine serviced last sept bobbin chamber oiled and cleaned regularly thank you.


This looks like bird nesting (also called thread nesting) or what I refer to as thread barfs. It occurs most often when the top thread is not seated completely in the tension disk.

Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.

Set the top tension to the midway point (which may need to be tweaked for your particular machine).

It may also help to pull the bobbin thread up to the top of the fabric, holding both thread tails in the left hand while hand-rotating the handwheel or slowly begin stitching with the foot control through the first couple of stitches.

My Pfaff Expression 2034 sewing machine is suddenly making an almighty mangled mess at the bottom - it doesn't matter how I re-set the tensions. What can be the problem?


Be sure to use a brand new needle.

Remove the upper thread and bobbin. Reinstall the bobbin making sure it is turning the correct direction and threaded properly in the bobbin case.

RAISE the presser foot and rethread the top thread. Confirm the thread pathway is correct.

Most often, knots (thread nests) occur under the fabric because the machine is misthreaded or the thread is not seated completely in the tension disk.

Tension on my Pfaff Grandquilter


check carefully that the top thread is actually gong between the tension plates and not behind them and jamming on the retainer bolt
before threading the needle place the thread up to the point of threading the needle and pull on the thread , proper tension is when there is a slight resistance to pulling the thread
If it takes excessive force to pull the thread then it is caught around something so follow the thread all the way back to the spool to see where the problem is

When I try to use the embrodiery unit the thread bunches up on the underside of the material--it is very loose. Any ideas on what is wrong?


The tension on the bobbin (under the deck) needs to be right. When you load the bobbin, try and pull out the thread a little. It should be firm. You should have to pull a bit to get thread out. If not, the tensioner on the bobbin is set wrong or has backed off (Or you loaded the bobbin wrong) Don't use the bypass slot!
There is one screw on the side of the bobbin holder, where the thread is pulled through when you load the bobbin. This screw can be adjusted to control the tension. See pfaff page on bobbins

I have a 7570 and cannot get the tension the bottom thread is loose and can be pulled right thru I checked the top and adjusted the bottom and nothing seems to change.


When you thread your bobbin in the bobbin case, hold it only by the thread. If the bobbin and bobbin case fall, the tension is too loose. If this is the case, turn the bobbin tension screw 1/4 turn until the bobbin and bobbin case do not fall when only holding by the thread. The top tension should be set between 4 and 5. The best way to see which one needs to be adjusted is to do a zigzag. If the thread is pulling more on top and your top tension is set between 4 and 5, the bobbin tension is too loose. If your top tension is set between 4 and 5 and it's pulling on the bottom, the bottom is too tight.

Pfaff varimatic 6091 sew a rag quilt with jean and flannel,I can't get my tension right it seems to be funny on the bottom stitch,where shoulf the top tension be set at 4 1/2 ,when do I adjust the bobbin...


Hi! The bobbin tension rarely needs to be adjusted. First, make sure you're using the appropriate size needle and thread for your fabric (I'd probably use either a 'denim' needle or a universal size 14) and also that the upper thread and bobbin are threaded absolutely correctly. These can throw off the tension! Also, take the time to clean out the bobbin area. That can throw your stitch off also.

If the stitch on the bottom is loose, so that you see the top threads, then the top tension is too loose. If the top stitch is too loose and you see the bobbin threads on top, then the top tension is too tight.

It helps to thread the machine with different color thread on top and in the bobbin, and then stitch an inch or so on the same type of fabric as you're using in your quilt. Check the stitch. If you need to adjust the top tension, make sure the pressure foot is down! Adjust a little, stitch a few inches, and check again. Repeat until you don't see any (or very little) bobbin thread on the top or top thread on the bottom.

If you go through all these steps, and the bobbin thread is still loose (and you've tightened up the top tension), then there is a tiny little screw on the side of the bobbin case that you can use to adjust the bobbin tension. Turn the screw just a little bit (less than a quarter turn), stitch, check, etc. Once the bobbin tension is set, you shouldn't ever have to change it.

Let me know if this helps, ok?

Happy sewing!

Zigzag stitch pulling tight, looks wrong


Try adusting the bobbin thread instead of the top. Always make sure to insert the bobbin so the thread is pulling in a clock wise direction. Both threads top and bobbin should have about the same resitance when pulled.

Tension Problem on Pfaff 2034, bobbin loops


Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.

Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.

Threading a pfaff 9020 sewing machine


all machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. 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 passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.
