SADLY CAN ONLY GUESS IT IS A TIMING ISSUE

My guess is sensor. I would think the belt has to go on anyway special as I assume it calibrates by going max x,y them min x,y every time you install table. Could be lint, thread, or other inside the table. Check the modular connector that plugs into the sewing machine, both machine and table for lint or other debris.

How did you bring bottom thread up after loading bobbin?
Do you have a manual for this model?

Make sure bobbin is oriented the right way, needle is not bent and fully seated in holder.

Parts #: X81375001

I could not find this anywhere. I expect its the backlight thats out. You can still see display graphics just poorly?

What size needle are you using. Maybe a larger size will help.

I don't know your history with this machine so some of the following may seem basic beginner.

Be sure you have the right bobbin. This machine uses a larger bobbin than other Brothers. The manual also indicates some x3817 came with "quick set" bobbin feature for which lower threading is slightly different.

If you need a manual for reference, it's free download from Brother at;

Extremely high top thread tension also may cause upper thread looping. You have tension at 3 which should be fine but there may be other issues affecting top tension.

Test top thread tension with needle up, presser foot down and tension at 3. Make a long slow steady pull of the top thread. The thread should advance smoothly through the needle eye with out snagging. Any sudden change in tension is suspect.

You can do a similar test of bottom thread. Bring bottom thread to top. With needle up, foot up, make a long slow steady pull of the bottom thread. Bobbin thread should advance from the hook case/bobbin smoothly with tension similar to the previous top thread test.

In general, the top and bottom tension should be near the same when top thread tension is set at 4. If you find an extreme difference in top/bottom thread tension at 3 then something is amiss. Re-thread per machine instruction.

I suspect top thread has looped around something or there's debris in the bobbin area.

If still a problem comment here with your findings and I or someone will assist further.

Check that the button hole lever is not somehow stuck in the back position.

The JX2517 has fixed height feed dogs. There is an optional accessory darning plate (XC6063021) that covers the feed dogs.

Its not the same model but look it over.
See pg 3-4 for tensioner as it's likely similar.

not sure if this will help you out.. Fixing common sewing machine problems Brother Sewing Machines Europe GmbH .or this one.. http://sew-hip.livejournal.com/2355177.html ..

It is most likely that the timing is off. This is a repair that needs to be fixed by a repairman. It usually costs between $40 to $125 depending on the service charge plus the labor involved.

can you explain more about the problem?
