I have a Bernina 830 sewing machine. I had a jam yesterday and a little smoke came out the back. Now, the needle arm will not move. Motor works though

If the touchscreen on your Bernina 830 sewing machine is not calibrated, it may be difficult to access the Service program soft keys. However, you may still be able to access the Service program using the following steps:

1. Turn off your Bernina 830 sewing machine.
2. Hold down the Reverse button and the Needle up/down button simultaneously.
3. While holding down these buttons, turn on the sewing machine.
4. Continue to hold down the Reverse and Needle up/down buttons until the Service program screen appears.
5. Once you are in the Service program, you can navigate using the numbered soft keys that appear on the screen.

As for attaching a keyboard, it is not possible to directly connect a keyboard to the Bernina 830 sewing machine. However, some users have had success using a USB to Serial adapter to connect a keyboard to their sewing machine. This method may require additional software and configuration to work properly, and it is not officially supported by Bernina.

Not sure I understand your question. Is that the old Bernina 830 Record? Removing the extension table will reveal the free arm. On the other hand, if you want to open the free arm to clean and oil, look inside the bobbin department and there is a little metal tab on the left top side that, when pushed, will release the cover.

For the newer computerized 830, here's the manual:

Take it for service. The burning is NOT a good sign!

Assuming it is an 830 Record (old mechanical, not the new computerized model). If it sounds like the motor is straining but the machine's mechanics are not working, then the machine has most likely seized from old, dried up oil.

This is the method I've used on multiple seized machines and works:
Wheel on right side that controls the needle up and down is very tight...

This is the oil port diagram for the 830 Record.

take it in for a service
could be foot pedal problem or motor problem

If it is the older Bernina 830 Record, could be some of the parts have seized due to lack of oil. Frequently, seldom used functions (levers, dials, feed dog control) are the first signs.

Wheel on right side that controls the needle up and down is very tight...

Be sure to move the dials/levers and apply oil there as well.

...

Um, not sure I understand the problem, however, it is recommended to never turn the handwheel backward. Always, turn it forward.

If it is an 830 Record, it may need a thorough cleaning and oiling. Open the top, the left side, and remove the free arm cover and apply 1-2 drops of fresh good quality sewing machine oil every place where metal rubs metal. Never oil the belts, plastic, or anything non-metal. Gently rock the handwheel and watch where things move and apply a couple drops of oil. Don't forget the feed dog mechanism and the levers & dials. Also get the needle bar and the needle position control on the needlebar. You can look around for little oil ports. There are several near the cams that are activated by the zig-zag control and stitch selector. Also several on the knuckles on the take-up lever, an important one in the back of the feed dogs next to the outer case, etc. There may be one on the back of the machine above the motor.

Be sure to run the machine on scrap fabric and clean up any excess oil before sewing on a project.


If it continues to squeal, it could be one of the belts. You might check to see if they are frayed, worn, or loose.

Motor brushes are usually the problem

Hi Rose Mary,

I'm assuming you are talking about the original Bernina 830 (their newest machine is also an 830!)

If you've not had your machine professionally serviced in awhile, it could be as simple as a good, thorough cleaning and adjusting. Your machine should be professionally serviced about every 1-2 years....not a bargain service that blows out the dust and puts oil on the hook, but a service that checks all the gears for wear, adjustments, hook timing, feed timing, grease for the gears (if required), removes lint build-up deep in the machine - very thorough.

There are various gears in the 830 that control these functions. It sounds as if one of the gears may be either broken or jammed. Unfortunately, unless you are trained in machine repair, this isn't something you should attempt. When gears are replaced or adjusted, generally the timing of the machine must be reset as well.

We would recommend that you take your Bernina to your nearest authorized Bernina dealer (they'll be trained on your specific machine and have easy access to any parts that may be needed).

If you do not know a dealer in your area, you can search on the Bernina website.

The original Bernina 830 was one of the greatest models Bernina has made and is well worth putting the money into keeping it running. Great machine!

Hope this helps narrow down what may be happening.

Happy stitching,
