Needle not lined up with hole in presser foot

Check to be sure you are using needles and thread that are compatible with the fabric. Generally, finer threads will work better on fine fabrics along with a smaller needle. Be sure to change needles frequently as dull, bent, or nicked needles will cause very frustrating issues.
All About Needles

Remove the thread completely from the machine. RAISE the presser foot and rethread from the beginning, making sure the thread path is correct.

Some machines have a presser foot pressure adjustment (consult the owner's manual). Adjusting the pressure that the presser foot applies to the fabric & feed dogs is helpful when sewing especially fine or heavy fabric. Also, when sewing fine fabrics, loosening the tension could be beneficial.

Changing presser feet may also help, ie try using a straight stitch foot vs a presser foot for zig-zag stitching.

Something else you can try is finding a presser foot with a teflon finish or a roller foot that will glide or roll with the fabric through the machine. Even if you can't find a brand name presser foot for your particular machine, an adapter shank can probably be found that would allow you to use snap-on feet of all different designs and uses. Provides a lot of choices for presser feet for less than purchasing a brand-name presser foot. There are snap-on kits available on eBay and other auction sites.

Some machines also can take a straight-stitch needle plate--usually an additional accessory that can be purchased. The hole where the needle penetrates the needle plate to access the bobbin thread is actually a small round hole. With a zig-zag needle plate, the hole the needle penetrates is a wide rectangular hole that can allow fine fabrics to be pulled down through the hole. Zig-zag capable machines usually have a zig-zag needle plate as standard.

There is a video tutorial on this Amazon page on how to use this attachment. Basically,, the forked arm fits over the needle clamp, and it attaches to the machine the same way any presser foot does. Check the video, it's very clear. The video is the last one of the group of small picture icons on the far left side of the page near the top of the page.

It should attach the same way any other presser foot attaches. If it is the square type with small holes or notches on each side, you move the needle to line up with one of those holes. If the needle does not have a separate side to side adjustment, usually you can move it using the width adjustment on the machine, as if you were going to stitch zig zag. If it is the long narrow kind, it will also have notches or holes on each side that you line up the needle with. Make sure the needle will go up/down without hitting the foot at all.

If the comment already posted did not answer your question, here is another thing to check. If the screw that attaches the foot and ankle to the presser foot bar is tight, and the foot can still be moved, it is likely that the presser foot bar has become loose within the lifting mechanism. You could save yourself some trouble by taking your machine to a sewing machine repair shop, but if you would rather avoid that expense, do the following. Remove the needle bar and take up mechanism cover on the left side of the machine. This is held on by a single phillips head screw on the back side of the machine, which, with the back of the machine facing you, should be on the top right side of the machine. Once this cover is removed you will be able to see two vertical metal shafts, one is attached to your needle clamp and needle, and should be in the front. The other is the presser foot bar, and will be behind the needle bar. There should be a small allen screw about halfway up that shaft that tightens onto the bar. With the presser foot properly positioned on the needle plate, tighten this allen screw. Don't tighten the screw too tightly, as this can damage the presser bar, just make sure it's nice and snug. Make sure the presser foot raises and lowers properly, and re-attach the needle bar cover.
Hope this helps.

Hi if the needle is hitting the needle plate you best get in touch with who you bought it from, The needle position is a critical adjustment and is done in conjunction with other adjustments.

try changing the needle
clean under the needle plate and in the bobbin area
and make sure you use every thread guide

Not familiar with your machine, but an important suggestion for all sewing machines:

ALWAYS RAISE the presser foot when threading the top thread. If you did not do this, remove the top thread completely from the machine and start over by RAISING the presser foot and following the thread path. (Do NOT miss any thread guides or thread any out of order!)

Lower the presser foot and thread the needle. (The top thread will pull through the needle ONLY if the presser foot is raised!) RAISE the presser foot and pull at least 5 inches of thread through the needle. Insert your fabric. Lower the presser foot. Hold the thread tail gently in your left hand and with the right hand manually turn the handwheel one rotation. The needle should pull the bobbin thread up through the fabric.

While still holding the top thread tail, "sweep" under the presser foot with a stiletto, scissors, a nail file (anything that will fit under the presser foot) to pull the remaining bobbin thread tail above the fabric. Grab both thread tails and pull them under the presser foot toward the back of the machine. Now, you are ready to take your first stitch.

You can gently hold those thread tails while you slowly power the machine to take the first couple of stitches on your fabric.

This has to be done by hand.
Raise the presser foot, then thread all the way down to the needle. Put in the full bobbin with thread end loose and visible. Hold the end of the thread in the needle with one hand and carefully turn the wheel so that the needle lowers and lifts the bobbin thread. Place both threads behind the presser foot. Now you can sew.

check to see if the presser foot is loose
check to see if the needle is in backwards
if the presser foot is tight & needle is not in backwards then it could be a timming problem, since you said the needle is hitting the presser foot
please rate this with the thumbs in upper right hand corner
