Why is the bobbin thread not picked up while sewing on a empisal goldline machine, model 2288?

Knotting occurs when your top thread and bottom thread are not properly contacted or do not interact correctly. Whenever knotting happens, you will notice that thread will bunch underneath the fabric. You can try re-threading the upper part of your sewing machine, making sure the thread is passing through every single thread guide on its way to the needle. If you find yourself constantly adjusting the tension of your bobbin thread, check the bobbin itself. Plastic bobbins especially can wear, causing them to grow loose within the bobbin housing and making it difficult to maintain correct tension. Try switching to a new metal bobbin and see if that resolves your issue.

Increase the top tension to pull the thread into the material.

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

Not sure what you mean by "tacking" stitch. Are the stitches exceedingly long like a basting stitch? That would need a stitch length adjustment so stitches are closer together.

Or, do you mean the tension is loose between stitches? You can try tightening the top tension to see if that helps. (Be sure to ALWAYS RAISE the presser foot when threading the top thread so the thread will seat completely in the tension disk or you may end up with lots of top thread showing under the fabric.) If the bobbin thread is too loose, you may need to adjust its tension.

Understanding Thread Tension Threads

It really depends on what You envision yourself doing with the sewing machine and then finding the machine that has the most functions that fit your needs.

It is your top thread tension causing the thread on the bottom of the cloth to be loose. Make sure your machine is threaded properly and the thread is seated correctly between tension discs.

Make small adjustments and do a test on scrap fabric until the stitches are tight.

Not quite sure since the symptoms are not clear. "Bumpy stitches from bobbin"--does that mean there were thread nests on the bobbin side of the fabric? That is thread nesting or bird nesting resulting usually from mis-threading, upper thread not completely seated in tension disk, or upper tension too loose. Remove the upper thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning--verify the thread path is correct. Set the upper tension to the midway point between high & low number and retest the machine. (Upper tension may need to be tweaked because fabric, thread, and age of the machine will have an affect.)

Check that the bobbin is wound smoothly--no lumps, bumps, or thread ends/pieces sticking out of the bobbin. Check that the bobbin is installed in the bobbin case correctly (turning the proper direction) and the bobbin tension is threaded completely.

If the upper thread is not picking up the bobbin thread, make sure to install a brand new needle. (I don't try to straighten or "fix" damaged needles. With today's computerized machines, it may cause more damage than a new needle would cost. That may work on the old mechanical machines like the Singer Featherweights, but my machines are too important to risk for the price of a needle.) If it still won't pick up the bobbin thread, then the machine's timing has probably been knocked out of alignment. Search for sewing machine timing or take it for service.

...

Usually, if the thread is bunching or looping under the fabric, the upper tension is too loose.. But if the bobbin thread is showing on the top of the fabric, the upper tension is too tight.

The tension is correct when both the upper and lower threads meet in the middle of the fabric.
