Question about Bernina Bernette Deco 600

1 Answer

Sews 1/4" and then sews in place

I have a Bernina activa 220. I can sew about 1/4" and then it stops and stays in the same place making a knot in the fabric but no knot or tangles of the thread underneath. The stitches are tiny even though it is set at the length that it sets itself when I turn it on. I have rethreaded the machine and the bobbin, changed needles (making sure the needle is the correct one for my manchine) and have cleared the memory. It is still having this problem. Is there something I am overlooking? Thanks.

1) remove upper and bottom threads. Try sew without threads.
Is fabric transported corectly?

- Drop feed dog button is OFF
- Dust under stitch plate
- Transporter malfunction (must be taken for a service to the BERNINA dealer)

- Upper or bottom thread jammed
- The upper thread tension is too tight.
- Wrong needle used (probably small ...)

SOURCE: Bernina Activa 130 I was sewing

You can check whether the alignment/timing has been affected fairly simply, as follows: Put a new needle in. Adjust the position of the needle fully to the left and try a straight sew-off ... if this works OK, but not when the needle is at centre, the timing is probably out. Drop the bobbin door and take the bobbin/bobbin case out. Turn the handwheel until the needle goes down into the stitch plate and just starts to come back up ... stop there. Carefully push the needle/needle-bar all the way to the right, so that the needle is nearly against the right-hand side of the slot in the stitch-plate. Lean the machine slightly back so that you can see clearly into the hook/shuttle area through the bobbin door. Release the hook/shuttle retainer by pressing the metal lever to the top-left side of the bobbin door. The black plastic hook/shuttle retainer should pop-open and you can carefully drop it down on its hinge to rest on the bobbin door. You can now see the hook/shuttle in its hook race and the pointed part of the hook should be to the left of the needle. Now, slowly rotate the handwheel so that the point of the hook continues to rotate clockwise until it just passes behind the needle. Look very carefully - the point of the hook/shuttle should be just above the top of the thread hole in the needle .... if it's below, or significantly above, the timing on your machine has been thrown-out by the needle breakage and will have to be professionally adjusted.

SOURCE: Why won't my Bernina Activa 140 sew the blind hem stitch?

Are you absolutley sure you're not getting a problem with stitch formation on, for example, wide zig-zag. Check again, using a different colour top and bottom and make sure that the stitch is being formed properly with only the top colour on top and bottom colour on the bottom. It sounds as though the bottom loop is not being picked-up by the hook properly. Make sure you've thoroughly cleaned-out any fluff under the stitch-plate and remove the hook/shuttle and give the hook race a good clean and give it a single drop of oil, even if you've got the lightweight part-plastic hook/shuttle fitted.

I can''t remember the steps to make a button hole using my Bernina patchwork 140. I have the # 3 foot. What button do I push to turn the corner manually?

you can download a manual for the Activa 145 here, buttonholing steps would probably be very similar for your model

It says you sew one bar, then press the reverse button and the automatic function then sews the bar tacs, other side, bar tack and finishes.

Needle threader is not working bernina 220 activa

Use a magnifying glass to see if the little hook in the needle threader is bent so that it is not going through the eye of the needle. You might be able to gently bend it back with tweezers.

Make sure that your needle is in the upper most position when you try and the presser foot is down.

Bernina Aurora 440 knotting below my fabric and into bobbin area.

Are you sure you have the bobbin the right way round in the holder....when you look at the bobbin and tug the thread, the bobbin should move clockwise.
Pull out the foot pedal and use bsr2 with the start/stop button.
Bring bobbin thread to top of work before starting to sew. This may help knotting problem

Needle always stops in up position

I have the Activa 131 and while the needle is made to stop in the up position, all you have to do is push the bottom of the peddle quickly with your heel and the needle goes into the material and stays until you start sewing again. Hope this is helpful.

Owners manual

Unfortunately this is a purchase site. The closest I could get would be for an Activa 220 230 240 . You can download the manual.
Check the picture on no. 7 and see if this isn't your machine.
Hope this helps. Luck!
