Question about Brother XR7700

1 Answer

Out of the blue mid-stitching, the thread knotted up on the bottom and I got an E6 warning. I have checked the bobbin and cleaned out the bobbin case. Nothing I am doing works. This machine is relatively new and I have only used it 3-4 times. I have been using sewing machines for over 30 years so I am fairly familiar with the workings and do not think this is "user error"

I kept looking for a bobbin problem (because this is what the book that comes with the machine indicated as the cause. As it turned out, somehow the thread on the TOP slid off the wire thingy that goes up and down when sewing. I noticed it totally by accident. After re-threading the machine, it worked like a charm.

I have juki 1541industrial machine . It started sewing upside down . Instead of nice stiching on top show side it on bottom. Any ideas


This is caused by the tension between the bobbin and needle threads being out of balance. If the knots between the stitches are on the bottom side, then you need to tighten your needle thread tension a little at a time until the knot is in middle of fabric. The reverse of this is if the knots are on the top, then either your bobbin tension is too loose or your needle thread tension is too tight. If this occurs, then loosen your needle thread a little at a time to see if knot goes down in middle of fabric. If it does not, then you need to increase the tension on your bobbin thread. This done by taking bobbin case out and tighten the small screw located in the middle of the spring on the side of the case. You only need a slight, steady pull on the bobbin thread - the more you put on the bobbin, the more you are going to have to put on the needle thread.

Handwheel is locked down


Several things to check. Did the needle break and jam in the bottom? Is the needle bent or did it jam in the bobbin area? I had a 'knot' of thread build up on the bottom and it hooked itself into the metal clip on the bobbin so that the needle couldn't raise. If thread jams in the bottom cut the threads until you can free the hoop and material. Check the bobbin for pieces of thread and fuzz. Check to see if the bobbin case or the throat plate is scratched or bent. If you are stitching Free Standing Lace on this machine or a piece with over 20,000 stitches I recommend starting with a new full bobbin and a new needle. As you get toward the bottom of the bobbin, thread seems to have a high likelihood of tangling or looping and will cause a jam which means the handwheel locks.

Bobbin thread keeps knotting


1. Do you mean that there are knots in the bobbin thread?
2. Is the bottom thread in your stitching looping and knotting.

If yes to 1. you need to rewind your bobbin fresh, and keep slight tension on the thread reel that you are winding it from. Put the handle of your scissors into the top of the reel to apply a gentle pressure while winding. Keep your eye on the bobbin as it winds and give it a nudge with a finger tip to ensure it winds the bobbin evenly top, middle and bottom.

If yes to 2, then you need to check your bobbin threading, is the thread even under tension. Is the bobbin tension set correctly. Break out your manual and revisit this to ensure it is set correctly.

Mine is doing the same thing. It's pulling the thread up from the bobbin and making a huge knot. Any suggestions. I've done all the above checks. Brand new needle, tension is on embroidery, threaded properly and no lint in bobbin compartment.

Bobbin Thread is "birdnesting"


Get out the manual and refer to the maintenance section for cleaning the machine.

Especially the bobbin area. You want to make sure the area around the bobbin case is free of lint and thread.

Use a new bobbin and re-thread the machine, with the presser foot UP.

Install a new needle, again according to the directions in the manual. Installed incorrectly can lead to mis-stitching.

If the problem persits, the timing may need adjusting.

This should be done by the sewing machine tech for Kenmore.

Sewusa.com has a guide for this in the repair section, but you could end up with more problems.

It keeps knotting up how do i solve that? Give me help or i will nicely **** u til u die......


Open the manual and refer to the maintenance section for cleaning. Clean away any thread or lint that may have accumulated.

Go to the front of the manual and follow the written instructions for winding and inserting the bobbin into the bobbin case.

Then follow the written instructions for threading (presser foot up is often overlooked).

Lower the threaded needle then raise while holding onto the thread tail.

Lift the bobbin thread and pull both threads under the presser foot and to the back of the machine.

Place fabric under the presser foot and while holding onto the thread tails, hand walk the first stitch and then use the power pedal.

If you have to stop mid-seam, or to turn a corner make sure the needle is down and this will help prevent mis-stitching.

Bernina Aurora 440 knotting below my fabric and into bobbin area.


Are you sure you have the bobbin the right way round in the holder....when you look at the bobbin and tug the thread, the bobbin should move clockwise.
Pull out the foot pedal and use bsr2 with the start/stop button.
Bring bobbin thread to top of work before starting to sew. This may help knotting problem

Problems with Singer 2732


"Birdnesting" occurs when there is no tension on the needle thread to pull the bobbin thread. This is easily corrected by rethreading the machine, following the threading path carefully and making sure the thread is fully engaged in the tension mechanism.
