Question about PfaFF Creative 7570
My Pfaff 2140 was working fine today when out of the clear blue, without any lockups from threads, I got the main motor blocked message. However, the machine will prepare for various stitches until you push the foot feed and then I get that message. I would have thought something might have the bobbin threads tangled, etc. but not the case. The wheel will turn. Is there anything I can do without having to call an out of town technician and take the machine to be looked at? I suspect it is something simple if I only knew what to try.
I have gotten the main motor blocked message several times. When I get this, I always remove thread, both top and bottom. I change the needle too. 75% of the time my problem goes away. If the problem is not solved, I unscrew the casing in the front of the bobbin, and look for anything that might be obstructing the bobbin. While I've had lots of "blocked motor" messages, I've never had to get a tech to ook at it. Sometimes, if you leave it overnight too, the sewing machine fairy will change something and the problem will solve itself in the morning. Re-thread, re-bobbin, re-needle. to start.

Always remember T-N-T. Thread, Needle, Tension. Assuming its threaded properly, is the needle all the way in and facing the right direction? These symptoms also suggest the bobbin may be in the bobbincase upside down thus turning in the wrong direction. Hope this helps.

Take the thread out of the top and bottom and turn the handwheel by hand to see if the machine will rotate smoothly.
Rethread, making sure that the thread is in the bobbin tension slot and that the upper thread is in the tension and the take up lever.
Sorry for the delay in response. I just found the sight this evening.

Basically on any sewing machine to time it you will need to separate the two gears that drive the hook. Usually loosen the set screws that attach the gear to the shaft and separate them.
Time the hook first. On center needle position, set the hook so that the point is behind the needle when the needle bar has risen about 2.5mm.
2) Set the needle bar height. Choose the needle position which is the last for the hook to pass.
(Left on most machines, right on older Vikings) At this point, place the point of the hook behind
the needle and set the needle bar height so that top of the eye is just barely below the tip of the
3) Check feed timing. Set the stitch length to the longest stitch. The needle should enter the
fabric just as the teeth drop below the surface of the plate.

This could either be due to the bobbin being wound too loosely, or the tension on the top thread is too loose. This just happened to me the other day, and I thought it was the bobbin thread, but then I put another bobbin in with a different color than the top thread (this is a huge help in diagnosing thread issues), and I was surprised to find that it was actually the top thread that was a big loopy mess on the underside of the fabric. I fixed it by tightening the tension on the top thread (quite a bit), and everything was fine.

Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.
Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.

It happened to me... Check the bobbin and thread in the shaft ... Pull out the bobbin and remove all thread from the shaft. Pull out any thread remains with the tweezers. Check the feeder dogs and the needle (see Owner's Manual 2:7). Re-insert the bobbin (see Owner's Manual 2:12).Make sure that you use a good quality thread and set everything up correctly. Good luck!
