Please take a moment to rate this solution thanks

The presser bar is not moving, there is a set screw that controls the presser foot height on the bar, it may be to tight. Take the side cover off, and look for the presser bar, the set screw unit should be facing you. Unscrew it and see if the presser bar handel will now move.

The presser bar height should be set at 7 mm. To make an adjustment loosen the set screw. From the top of the machine, press down firmly on the presser bar and then secure the set screw.

you may have some lint not seen and use some canned air and try that you may need a new needle it could be bent. or even broken and a piece is still in the little tight crease in the bobbin holder.try all that first and then check your tension did it get moved by the fabric? when you wrer making the curtains?

The solution to the threader being higher than the needle: Use the handle on the right side to manually raise your needle up to it's highest point. Thant should work!

I just place my finger on the thread to make it tighter going to the bobbing, that may not be a fancy solution but it worked for me, Thanks

Does the winder spin freely by hand? If so then it needs to be adjusted, maybe a new bobbin tire also. If not then try oiling it and freeing it up by hand.
Hope this helps.

Your machine is telling you that you have missed a step.
Probably the buttonhole lever is not all the way down. it is left of the needle at the top of the machine by the lamp and has a picture of a button hole on it.
Hope this helps

I don't know if this will work, but sometimes the thread in my machine gets too tight because I hold it in place with a water bottle cap, but then my needle gets pulled too far away from where it is supposed to go, and it bends and hits the bobbin plate, and then it just breaks.

Try to sew slower. In my sewing class the bobbin always freezes, and if I go slower it works better sometimes.

make sure the bobbin winder is not engaged and thread the machine over ,also check that the buttonhole switch is not down

you have to lift the presser foot and guide it through or pull it through slow - i knw no other way around this unless you have an industry type machine

If this is the machine I think it is the bobbin case is completely round as opposed to half round. If it is half round ignore the following.
Remove the presser foot and then the two screws which hold the needle plate. Lift off the needle plate and then lift out the old bobbin case. Clean all the lint out and then insert the bobbin case so that the less round part of it is to the back and the lip around the bobbin case is resting on the lip around the hook. Turn the hand wheel a few times to be sure it is working smoothly and not binding. Replace the Needle plate , bobbin and presser foot. Insert a new needle,thread the machine, Check your tension to be sure it is working correctly, turn the hand wheel again to be sure it is picking up the thread without binding and sew.

guide the the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)If it doesn't work like this, then there is probably thread stuck inside the tension assembly. Set the tension to zero and blow hard between the discs to dislodge the thread. If it passes this test, continue up through the take up lever,then down through the thread guides to the needle.
Check to be sure you have the correct bobbin and that it is inserted the correct way.
OR remove the needle plate to remove the bobbin case. Look for any burrs or rough spots. Use a fine emery stick and steel wool to remove and buff them Reassemble and try again.

It might be the way you're asking that's confusing the problem. It's simple to remove the hand wheel, slip the belt over the track, and then replace the hand wheel. It really depends on the model of your machine - is it by chance a 328K?
