I have and Elna su sewing machine and i can't get it to zig zag. Please refresh my memory on the settings i should have it on.

If the zig zag function on your Elna Carina sewing machine is not working, there could be a few possible causes:

1. Incorrect stitch selector: Make sure you have selected the correct stitch on your machine. Double check that you have selected the zig zag stitch, and not accidentally switched to another stitch.
2. Incorrect stitch width: The stitch width knob on your machine controls the width of the zig zag stitch. Make sure that the stitch width is not set to zero, as this would prevent the zig zag function from working. Adjust the stitch width to the desired size.
3. Tension issues: If the thread tension is too tight or too loose, it can affect the zig zag stitch. Check your thread tension to make sure it is set correctly.
4. Clogged machine: Dust, lint, and debris can accumulate inside your sewing machine and affect its performance. Clean your machine thoroughly, including the bobbin area and the feed dogs.

If none of these solutions work, it may be necessary to have your machine serviced by a professional.

Question edited for clarity.
Question moved from Washing Machines to Elna.

It is a good old workhorse and I would say worth repairing. The new ones are also more unreliable because they rely heavily on computer electronics.

Hi,

a combination of belts, cranks and power help to move the needle in your machine.

If you're interested in learning more about the mechanics of your device, you can contact Elna by dialing +41 22 884 86 66

Thank you.

Suspect the machine has seized due to lack of regular cleaning and oiling.

Elna Carina Electronic SU Duplex Review

Wheel on right side that controls the needle up and down is very tight...

Even if it has been oiled regularly, has it been "thoroughly" oiled--ie, all the points where metal rubs against metal? Following may be helpful:

No, the Carina came with a standard zig zag plate and 5 feet I think from memory, the teflon coated foot , the embroidery foot, buttonhole foot, zipper foot and darning foot.

Yes, because a zig zag stitch is creating a wide stitch and the tension on the thread is going to pull the fabric within the seam together, you can't seam thin fabric with a wide zig zag. It will "tunnel together". If you are using this stitch to neaten a raw edge, then try using the serpentine or three step zig zag where the needle pierces the fabric 3 times in each leg of the zig zag, this will give better results.

I have looked but can't see a manual, but looks like push button stitch selection on front of machine, often it will be same as straight stitch, but need to take stitch width from 0 to 4

Simply turn the dial to get the zig zag setting. Manual in the linky

Sounds like the pattern selector is bound up. Make sure your zig zag is set to zero when changing patterns. That may help.
