Basic Sewing Machine Maintenance Tips From an Expert

Anthony

go on line and find a service agent for your machine and take it in for a service.

If machine misses stitches consistently, it can be several things.
Needle not installed correctly, not threaded correctly, Bobbin case not installed correctly, make sure the bobbin itself is inserted correctly and spinning in the correct direction.
Finally, machine may need service the timing is off. All actions of a sewing machine are carefully "timed" to form a stitch while sewing. Sewing things that were too heavy for the machine or you hit the bobbin case while sewing can knock the machine out of adjustment.
Let a professional do the maintenance on your machine. Some may opt to show you how to do more in depth maintenance yourself at home.
Cheers,

I would call Brother at 1-800-276-8437 and complain that you took it in to their authorized service center and the problem is even worse. I would try for a new machine or them to send you a call tag to fix it themselves. A machine only a year old should not have that kind of problem. Be assertive and not afraid to speak up. You deserve better service.

Refer to your manual for the following:

Cleaning and lubricating (maintenance section).

Threading - sometimes we forget to have the presser foot up and this can have a negative effect on the stitching.

Tension settings.

Needle size and style for the type of sewing being done.

If the problem persits, the machine needs to go into the shop for service. Take a sample of the stitching with you so the tech can see what is or is not happening.

After it has been serviced, ask for a "test-drive" before taking it home.

No oiling a computorized sewing machine. These areas are factory sealed and only serviced by a Brother tech.

Refer to the care and maintenance section of the manual for cleaning as this needs to be done more often with sewing/embroidery machines that have the drop-in bobbin.

Look for thread snips and lint.

Raise the needle to it's highest position before removing and replacing the bobbin case.

You can get a manual, if needed at the Brother website to view or download at no cost.

Eventually you will have to take the machine in for service. The site has a dealer locator, if needed.

Refer to the maintenance section of your manual.

There may be thread in the bobbin area that is causing the jam.

If you cannot resolve this with routine cleaning and maintenance, you will need to take the machine in for service.
