Could not sew buttonhole . The tread gathered in one spot and wouldn't move further

Hard to assist without a make/model.

If it has a built-in buttonhole function, you may need to take it for service.

If it is a function you have to do manually, then you probably need to set the stitch length a little longer. A shorter stitch length will cause the needle to stitch on top of the previous stitch causing a big knot of thread.

Singer advance7422 burst the tread

When you thread the top do it with the foot in the up position. As you thread you should notice the ease of movement through the tension, holes, etc. If you come to a point it is sticking, check why. The tension could be a problem. Anyway, if you don't seem to have a problem hear then put your foot down. Pull on the thread to see if it is stuck or not moving with an extreme amount of difficulty. You may need to lower the tension. A good starting point is 3. I expect your tension is the problem. If it is still the problem then lower the bobbin tension slightly. By the time you finish the knot should be in the middle of the fabric. Sometimes there is one more problem It is the thread is poor quality and is unravelling in the needle hole. Observe this closely as you sew. You know what to do if this is the problem.

Problems with sewing, the thread keeps getting knotted up I the bottem. The spool of thread that is on the top is wrapping around the stick when trying to sew?

Try changing the needle if that doesn't work try adjusting the foot pressure. I had that problem with one of my quilts and It was the presser foot. I used google to find a lot of answers for machine problems, You would be suprised how many answers and utube videos you will find to show you how to fix things.

How to set the tension

The carrier and bobbin are removed. Place the thread in the carrier with the thread dispensing counterclockwise. Place the thread between the metal pieces (tension). let the carrier hang from your finger and bob it slightly. It should extend one inch. If it doesn't then you can adjust it by turning the small screw slightly until it does what I said. Now, replace this assembly. The top tension you can start at three. The sewing should be an even pull between the upper and lower thread. If the thread knot is in the center of the material it is right. If the knot is under the material then raise the upper tension. If the knot is on the upper material then you should lower the upper tension. The key is to start with the bobbin tension correct and adjust the upper tension until the knot is in the center of the fabric

How do I adjust the tension on my Singer 621B model I have had it for 20 years and the tread breaks every time I try to sew with it?

Put the top tension on 3. The bottom bobbin carrier remove. The little plate on the carrier has a screw to tighten and loosen for the bottom tension. Allow the thread to drop the carrier about two inches from your hand and move up and down lightly. The carrier should extend slightly when you do this. If it doesn't do it then loosen. If it does it too far then tighten. Make sure that your bobbin is rotating counterclockwise. The top may have to be adjusted by the fabric you are sewing but three is a good start.

Can not get machine to work, no manual, knots up and breaks thread right away 20 15516 machine can you help?

First check in the bobbin area for lint, bits of thread wrapped round parts.

Then make sure your needle is oriented and inserted fully.

Also when starting a seam be sure to grasp both of the threads and hold them as you start to sew.

If you still have problems, make sure your thread and needle are suitable for your fabric.

Since you don't really say where it knots and breaks ... it could also be a damaged needle plate.

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

Bobbin thread one big snarly knot

First ensure that your bobbin is threaded correctly. Most drop in style bobbins the thread will feed off in a clockwise motion. Also make sure to only move the hand wheel (on the right) toward you (counter clockwise). When you begin sewing ensure that you start with the needle in the fabric and when you end that your needle is in the highest position.
