When the hand wheel is manually operated it then makes a clicking noise near the presser foot

Hello Mary. The bobbin winder on the top is what's making the presser foot switch to go green when in the up position move the bobbin winder to its stop position and the presser foot switch will reset. Buy a manual online £4.99.

Be sure to RAISE the presser foot when threading the machine so the tension disks are open to accept the thread. It also helps to grasp the thread between the thread tree and the tension disk and with the other hand grasp the thread below the tension disk and give the thread a little tug to make sure it is seated all the way in the tension disk.

Of course, make sure that the machine is threaded in the proper sequence--check the owner's manual (usually the upper looper is threaded first, then the lower looper and the lower looper thread tail is draped Over the upper looper in the last step before being pulled under the presser foot).

If the thread breaks or comes unthreaded, Best Course of Action is to remove all the threads and rethread from the beginning. Nine times out of ten, trying to rethread one thread will not work!

Also, when removing thread, it is not a good idea to clip the threads between the thread tree, raising the presser foot, and then grabbing the thread tails at the presser foot and pulling all the thread ends down. Threads should not be pulled UP through the tension disks.

Google for a manual or service guide.

Your machine is complaining because it doesn't have the power to push through the layers of fabric. That clunking noise is the gears in the machine skipping and being sheered off (or it will be eventually) STOP!

If you feel that you need to continue... stop when it does this noise and use the HAND WHEEL. You'll also need to make sure that the presser foot remains level while going over thick seams.

Remove the thread from the machine. Install a brand new needle.

ALWAYS RAISE the presser foot and rethread the top thread. Set the upper tension to the midway point.

Insert the bobbin in the bobbin case (make sure it is turning the correct direction) and thread the bobbin tensioner. Install the bobbin case in the machine.

Insert the fabric under the presser foot. Lower the presser foot. While holding the top thread tail with your left hand, manually turn the handwheel (always toward you, never away!) one revolution until the top thread has pulled the bobbin thread up. Raise the presser foot and sweep both threads under the presser foot toward the back (you can use a stiletto, a pencil, or some other tool to sweep the threads). Lower the presser foot, gently hold both thread tails with your left hand and slowly turn the handwheel (either manually or by motor) to form a couple of stitches. Then let go of the thread tails and continue sewing.

If it continues to cause thread nests or you have other issues, then your machine may need service.

it needs to be checked by a sewing machine repair shop to see what wrong with it

The needle either not moving or stopping is a sign that the machine is jamming. Here's the answer for the question "My machine is jammed" from the FAQs on Singer's web site at http://www.singerco.com/support/faqs.html

A jammed machine is caused by thread being caught in the hook. Remove the upper thread and the bobbin case, turn the hand wheel towards you (counterclockwise) by hand and remove any thread in the bobbin case area. *Always turn the hand wheel towards you. Turning the hand wheel away from you (clockwise) can cause the machines timing to become unaligned and jam your machine. Also, always make sure the presser foot is in the down position before you start sewing. Sewing with the presser foot in the up position will jam your machine in the bobbin case.

Your description of the needle hitting the plate or foot is an indication that the machine's timing has become unaligned which can be caused as indicated above by turning the hand wheel away from you - the correct way is to *Always turn the hand wheel towards you.

Noise can be from lint in the bobbin area.

After cleaning, re-thread the machine with the presser foot up to see the combination of cleaning and "presser foot up" threading helps.
