My Singer machine is an easy-thread type with auto tension. It was sewing fine when suddenly the bobbin thread is all just loops. I can pull out the bobbin thread after I sew a line. The auto-tension does nothing to change the problem. Can you help me? I live in the bush in Tanzania and have no sewing machine repairman within hundreds of miles!

This is an answer to another person with a similar complaint. Try the suggestion below, it may fix the problem.
From your description it appears that you have tried tension settings on the upper tension control adjustment knob without success.
Check that the bobin tension is adjusted correctly by taking out the bobin complete with the spool.
Pull the cotton thread and it should be a smooth light pressure if the tension is correct. If it is tight to pull or pulls freely then adjust the tension screw which is found on the outside of the bobbin. The screw is very small and requires a minature size screwdriver. The adjustment will only be a slight turn of the screw one way or the other to obtain the correct tension(depending if it was loose or tight).
Once this is set reinstall the bobin and tread up the machine, hopefully with the upper tension set at approx."2" the machine will sew correctly.

I believe you have a broken gear. These are difficult to repair on your own.

Have you checked the top thread is correctly placed in the spring of the bobbin case?

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.
