Sewing machine blocked

is there an oil hole on the hand wheel near the hub? if so then put a couple drops of sewing machine oil in there and it should go back to working .

Force the handwheel in the direction of travel. You can't break it. Then remove the needle and bobbin and run the machine 15 seconds at full speed.

There may be thread caught in the bobbin area which is not allowing the hand wheel to turn. Remove the bobbin case and check the hook for threads wrapped around the spindle and/or caught in the hook mechanism. A little clear sewing machine oil in a pipe cleaner is sometimes helpful in freeing threads in this area.

Use the zig zag adjustment while in straight stitch to move the needle position to the left or the right

It sounds like something is blocking the lever from coming all the way down. Clean and oil. Look for bits of lint or fabric. Use a flashlight and look very carefully and you may be able to see the obstruction.

You definitely should take your machine to a pfaff tech! This is not a diy type of repair.

Where has it been for ten years? This could have a big affect on an electronic sewing machine.

Take the machine in to a sewing machine shop for service.

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.
