Question about Janome Sewing Machines
The stitches underneath the fabric look ok but the top stitches look like the thread has not gone through the fabric to join the bottom thread so the bottom thread is just a tiny loop on the top of the fabric with the top thread running through. Sorry if it's a jumble but I don't know how to explain it better. Thank you, June.
Generally, if the thread issue appears on the top of the fabric, it is the result of a bobbin thread problem. In your case, it is probably something to do with the bobbin tension or threading. Remove the bobbin from the bobbin case. Make sure the thread is would smoothly on the bobbin. Check that when the bobbin is installed in the bobbin case that is turning the correct direction (consult your owner's manual). The bobbin turning the wrong direction will affect the tension. Also, verify that you are threading the thread through the bobbin case tension spring properly.
Further, if the upper thread is pulling the bobbin thread to the top of the fabric, the upper tension is too tight. The factory standard is usually the midway point between high & low number.
Since your machine is relatively new, it is probably still covered under warranty. You can have a Janome dealer check it for you. New machines sometimes are defective.
The following sites may be helpful. Keep in mind that adjusting the bobbin tension screw is a last-ditch effort, as tiny adjustments can make a huge change. It is easy to get it further out of adjustment. Be sure to mark the original screw slot position BEFORE making any changes so you can reverse them if things get worse.
