Why doesn't the top thread of my sewing machine pick up the bobbin thread?

I have a Singer fashion Mate 7256 sewing machine. I have cleaned all the loose threads and change the needle, also re-threaded the bobbin and machine. The top thread won't pick up the bobbin thread? Why is it doing this?

I haven't sewn in years, this is one of the reasons why. I looked for your owner's manual, did not find it but I did find a sewing site with discussion around this same issue. I attached the link below. Hope this helps while you wait for the expert answer.

Thank you for your question.

Some of the reasons why the needle will not pick up the bobbin thread, you have already done.

Make sure the needle is in correctly. Check to see if the needle is not in backwards.

You said you have cleaned the bobbin case and the upper thread path. This is a good practice. The schuttle hook raps the upper thread around the lower thread. If the timing is not correct the hook point misses the time when the needle delivers the upper thread to the schuttle hook point so it can pick it up.

One thing I would like to have you check will require you to remove the bobbin case cover and the needle plate,next remove the bobbin case. What we are going to check is the needle to schuttle hook timing.

Return any settings to zero. Zig Zag to 0 and the stitch selector to strait stitch center needle position.

Slowly turn the handwheel by hand until the needle bar is at the top of its travel. At this time I will need for you to locate the point of the schuttle hook in the schuttle area where you removed the bobbin case.

As you slowly turn the hand wheel, observe the needle and schuttle hook location. As the needle comes to the bottom of its travel and just starts back up the schuttle hook point and the eye of the needle should intersect at this time.The schuttle hook point should pass behind the needle right above the eye in that flat spot on the back side of the needle. Remember that the schuttle hooks rotates two rotations to one needle stroke.

If the needle does not intersect with the schuttle hook point as mentioned above. The machine will need to be re-timed. You will need to take the machine in for service. This situation can happen sometimes when the needle gets jammed in the schuttle assembly and the handwheel is forced and this can cause the timings to slip out of adjustment.
