    decorative stitches don't work. There are some arrows in red next to the bobbin that show up and down. Could this be to widen to a zig zag?

Take the thread out of the top and bottom and turn the handwheel by hand to see if the machine will rotate smoothly.
Rethread, making sure that the thread is in the bobbin tension slot and that the upper thread is in the tension and the take up lever.

Sorry for the delay in response. I just found the sight this evening.

If thread is bunching up under or at the bobbin (White 1740) and it clanks, check if the needle thread has come out of the upper arm. It can easily slip out of the slot. I have wound a narrow band of tape on the slot to prevent the thread from escaping. Leave enough opening to put the thread through when threading the machine.

When you wind your bobbin make sure you use even tension. Do not wind it to tight or to loose. Do not overwind it. Make sure that you are thread the bobbin correctly. Also do not sew at top speed. Use a slow to moderately slow speed.

So your set up to sew zig/zag and only get the zig or the zag : )

Could be top thread tension is too high. Switch to a straight stitch and reduce tension until top thread starts to appear on bottom. Then go back to zig/zag and see if it sews properly.

If still dropping stitches, check the needle is not bent and is fully inserted into the holder. Clean the bobbin, hook, and race per machine instructions. Try reducing the stitch width and see if that makes any difference. If still not right then timing may be off.

Do you have it on zig zag or maybe it is in one of the hem stitches. Make sure you have not selected a special stitch. Sometimes with a small width setting it looks like no zig zag, then when you increase the length you see it is not.

What size needle are you using? You should be using at least a #14 or #16. A #11 is too light duty. Try that and see if it doesn't make a difference.

Ask at the shop where you bought it, take a sample and arrange a time to meet & discuss if it is under warantee.

Suddenly zig zag stitch not working?

Because it is almost a straight stitch but the needle continues to move in a zig zag fashion is reason to believe it is in a long stitch. By changing the number of stitches per inch there will be a very noticeable looking zig zag stitch.
