Can i use brother se 400 in india - Brother SE400 Computerized Sewing and Embroidery Machine

I don't think you can because it has no 'memory' function as to how many stitches it has performed or where it is within the pattern.

I would have thought the maker could supply parts for everything they have sold. Contact them direct. Make sure your repair shop is an authorised service centre.

If you can see that the tread is there and in the correct place, the Thread Out sensor may not be working right.
Our solution with several Hus Rose machines was to disconnect the Thread Out sensor.

You may need a shank adapter. Most dealers have them available.

I used generic on my se 400 and worked fine.

Yes they should unless the tab on the middle of the embroidery unit is broken.

That means that there is no rotation in the main motor and assuming that the hand wheel moves when you turn it by hand, its likely the motor has a serious problem.
I advise you to take it to your local Brother dealer for repair.

You just need a new blade!!!
