Might sound simple, have you just tried rethreading it a few times? The bottom bobbin thread might be stuck on something.

Trying to sew zigzag but the bobbin thread is showing up on top

1. Try to loosen the top tension first.
2. If this doesn't work remove the bobbin and tighten the bobbin.
3. The purpose of this is to have the top and bottom tension even. This is similar to a tug of war. Whichever way is stronger is where the knot will be going. You want the knot in the middle of the fabric.
4. Test your top tension by leaving the foot up. Pull the thread through back and forth. It should be easy. If it isn't you will need to adjust the tension mechanism.

There is a tension set document added to help you.

Bottom thread is still loose even if i try to balance the tension, how do i balance the thread tension?

You bobbin tension CAN be adjusted. First, thread your machine with different colors in the top and bobbin, set your top tension at its default, and run a line of straight, and then a line of zigzag stitches, and compare the results at the top and bottom. You will be adjusting your bobbin to your top tension. If the top tension looks like a straight line instead of stitching and the zigzag looks like "chicken tracks" instead of a zigzag, but the bottom looks like a zigzag, your bobbin tension is too loose.

Remove the bobbin case, and locate the straight-slot screw. There are generally two; one is a Phillips and one is straight--you want the straight one. Leave the other alone.

The rule is "lefty-loosy, righty-tighty." If your stitching displays the above symptoms, it needs to be tightened, so turn 1/4 turn to the right--no more--then test again. You will need patience, but don't turn more than that. It is easy to do, but if you don't do it systematically, you can make things worse, and very slight adjustments can alter the stitching significantly.

Why is the bottom stitch straight

Thread tension is a BALANCE between the top tension and the bottom tension. It appears that your bobbin tension is sightly tighter, causing the top thread to be pulled down. Run a zigzag stitch. If your top looks fine, but your bottom looks something like chicken footprint tracks, see if you can adjust your top tension a little tighter to compensate. If, in doing that the stitches are balanced but just too tight, you will need to adjust your bobbin tension SLIGHTLY looser. You will need a tiny screwdriver to do this. Take the case out and locate two screws on the side. Once is a Phillips--leave it alone. The other next to it is usually on the left of the Phillips, and, is a straight-blade screw. Lefty-loosey, righty-tighty. In your case, you want to adjust it a LITTLE looser to match the top tension--no more than 1/4 turn. Put it back and test it again; you should see some improvement. If it still needs a little adjusting, reinsert and repeat, but ONLY 1/4 turn at a time.

DON'T fool with it at all if you can compensate by tightening your top tension, and before you do anything, clean and oil your bobbin area with ONE drop and ONE only of sewing machine oil.ONLY. You might find that just cleaning and oiling will solve your problem right there.

Top zigzag is fine, bottom is loose

I'm sewing a zig zag stitch and the underside is a perfect zig zag and the upper side looks like it should be the can I fix this so that the beautiful zig zag is on the top?

FIRST > Make sure your bobbin case is threaded correctly...

For normal straight sewing the top tension should be around 5, for zigzag or satin stitch you need to lower your upper thread tension a bit. Try it at 4, if it still pulls your bottom thread to the top try it at 3 etc...

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.

My four-year-old XL3500 seems to have a tension problem. It was sewing fine until after I refilled the bobbin, changed thread twice, and did some zigzag stitching. Now the top stitch is not correct; it...

according to the diagram in the manual, the upper thread tension is set by the wheel/knob on top and just to the right of the thread take up lever and thread guide. If you don't have a manual, go to they have a downloadable manual for your machine.

Juki HZL-E61: cannot get tension right on straight stitch

Loops on the bottom of the fabric direct the problem to the top thread. Rethread again and make sure the thread goes through the tension discs. Lift the foot, because this is what opens the discs. When sewing and the foot is down, the discs should be closed and thus giving the upper thread the tension it needs.

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.

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.
