PFaffselectronic 6250 presser bar stuck in up position frozen
I have oiled. The lifter goes up and down but does not seem to be connected or affecting the bar to the foot. I have tried to see if anything is affecting its movement but it just won't budge. Machine was not overly dirty, bought it used did not realize this was an issue.

tilt machine back and look at the lifter bar. try moving it now without any pressure on it. move ok then problem too much presser ft tension of the lifter plate on the vertical bar under the machine is bent or not high enough or not align with the botton of the part the machine thta connects to the presser ft. the lifter bar connected to the knee lifter can be bent to line up with the bar on the machine. go to the other side of the machine and look in thru the oil pan to see how they match up.
Is your machine fitted with a knee-lifter ? If so, its possible the knee-lift mechanism has got stuck, which will prevent the foot from coming all the way down. It's also possible that the foot lifter bar has slipped which will require re-setting. When the foot is lifted and the feed-dogs are dropped, there should be a clearance of about 7.5mm between the underside of the foot and the stitch plate.
Hi, the presser foot bar needs cleaning and oiling. Open the cover over it if you can or just go at it from the bottom. It may be best to clean it with something with kerosene such as liquid Wrench from your local hardware store or a gun barrel cleaning solvent. Then a clear sewing machine oil and exercize it good until it starts snapping down again.
If you can't lift the presser foot up at all undo the presser bar screw on top of the presser bar, if you have a dial turn it to 0, you should now be able to move the lever, if it is still tight put some WD40 on the presser bar and leave it for a couple of hours.
I have seen these machines with broken presser bar clamps (something inside the head). If it is just a bind then some oil on the presser bar may work, if the clamp is broken then it is probably not worth fixing. Good luck!
