In order to solve this problem the best thing is to make sure that your thread is not wrapped around the pin of the winder.

2. Hook Problems
This is also another common problem with the Bernina 790 Plus sewing machine.

The best way to solve this problem is to clean the bobbin area and remove any lint or thread lingers. You can also adjust the tension on your bobbin case and then clean any debris from the sensor on the bobbin door. If the problem still persists there is a chance that the hook timing has been damaged and you will need a professional repairer to take a look at it.
3. Needle Bar Jammed
Another common Bernina 790 Plus problem is that the needle bar usually gets jammed because of different reasons. For starters, the needle bar usually gets jammed when there is a thread tangle on the fabric you are sewing. If this is the case, you have to rethread your machine and test the tension before continuing to sew. Another reason why the needle bar may get jammed is because your hand wheel might be faulty, therefore, you need to check it and have it fixed. Lastly, you need to oil the needle bar area regularly in order to prevent this from happening.
4. Thread Breaks
The Bernina 790 Plus usually faces problems of upper and lower thread breaks. This problem is usually caused when there is an incorrect needle to thread combination.

In most cases it will have scratches and dings which usually cause the thread to break. You should also check the quality of your thread, this is because poor quality threads usually tend to break especially when they are exposed to too much tension. Therefore, always make sure you use quality threads.

In order to solve the problem make sure you insert the needle using the correct method, you can refer to the manual if you like. The needle can also break if the fabric is pulled. In order to solve this you need to feed the fabric evenly onto the sewing machine.

How Do I Fix The Tension On My Bernina Sewing Machine?

- Replace the needle and put one that is fitting for the job you want to do.
- Once you have replaced the needle check the bobbin and make sure it is spinning in the right direction.
- Use the same type of thread for the bobbin and the top thread, this is because using uneven threads can cause tension issues.
- Rethread the entire sewing machine making reference to the manual.
- Take a piece of material and sew test stiches. If the bobbin thread appears on the top of the thread you have to lower the tension. If the top thread tangles or sags under the fabric you need to increase the tension.
