I am slightly familiar with older sewing machines but not modern machines. It is a long time since I've seen my machines. If your presser foot has a wide slot it is clearly possible to use it for zig-zag sewing. If the machine is capable of zig-zag or swing needle sewing, it is sometimes possible to swing the needle and fix it to the left or right and fix it in that position. I suggest you check in your machine instruction manual. Perhaps the presser foot you are using is unsuitable for your machine...

The first thing to try is the fuse. The best way to do this is swap the machine's fuse with that in your kettle's plug - this should also be 13 amps as on your machine. Also, it is possible that there has been a power cut; even though these are rare they can happen, so do not dismiss this possibility. The final thing to try is to move the cable and see if the machine will come on. If the machine comes on then you will need to contact the manufacturer for advice about their repair service

Is this a new machine or have you had the problem before
