How to Identify and Fix Common Vacuum Problems ?

If you are using the correct needle for your fabric, thread, and the technique you`re doing but are still getting skipped stitches, try pulling out and reinserting the needle. Ensure that it`s not inserted the wrong way, slightly rotated, or not firmly inserted all the way to the top.
Bobbin tension that is too tight can cause thread breaks, misstarts, puckering, and design registration issues. Bobbin tension that is too loose can cause bobbin pull to the top of the design. A dirty bobbin tension spring can mimic any of the problems above.

We have brought the Bernina in, set it up, oiled it as specified in the manual, with the original sewing machine oil. We have correctly threaded the machine and the bobbin thread is up.
When we press on the pedal to sew, the machine gets electricity and buzzes
From what you describe there can be only 2 causes…Either the machine is still stuck ..and the motor buzzes cause it can not spin it ..and in this case it needs to be oiled more..and be spun by hand until it moves well and free…and after that it will work ..or during the storage ..from condense or so ..the motor is stuck ..and needs to be checked…In this second case ..it probably need to be oiled too (the motor ) ..and the coils changed..
Have a nice day ..!
Disassemble your bobbin case which is realy quite easy, clean.thoroughly with a brush and air, paying particular attention to any.rust that may have formed, and any thread that may have weazeled it’s.way into small but very incremental areas of your case.
Make sure your needle is not in backwards.The rounded side should be on the outside
. If threading is correct and your tension is properly adjusted , then check the hook for scratches. If you have ever hit the hook with a needle, it will be scarred and will catch the thread every time the upper thread passes around the bobbin case. the hook is the sharp point on the shuttle that holds the bobbin case. If it is scratched, polish it smooth with VERY fine sand paper
Make sure that your thread arm that rises and falls, constantly having tension running through it and that it is in fact staying in place.
Alternate between the metal and plastic bobbins – sometimes the plastic bobbins tend to chip
.Go slower with the pressure foot speed and use the right needle.ALWAYS test on scrap of your sewing material first!!!
.I have this machine for like 2 years and can do 2-5oz cowhide and buffalo leather on it (no joke, and it works FLAWLESSLY) inside it has full steel construction,just needs regular oiling compared to pro machines and easily made a few grand $$$ with it while my pro machine is getting repaired (I don’t even bother with my pro machine anymore). But you MUST oil it every month and use the RIGHT needle and adjust your tension properly .
.Also pull out the thread a good 6 inches from the needle and bobbin before dropping the pressure foot and sewing..
.Best $70 bucks (WITH TAX) I spent hell,the leather I use costs more than the machine!
1st: Sewed one inch OK; moved fabric and it stopped sewing, motor made thudding noise. When push-button (NOT pedal) is used, gives error E6,
consistent with motor noise.
2d: In order to check threading had to manually PULL bobbin case toward me or it was UNDER needle plate. Cleaned a fair amount of dust out. Reinstalled bobbin, etc., per manual, rethreaded.
3rd: Will sew 2-3 stitches, then packs up again just like in 1st instance above. Have st
