Swiss Bernina sewing machine company began selling household sewing machines in 1932. Bernina has become one of the best-known sewing machine manufacturers in the world. Bernina sewing machines are famous for their reliability, and they hold their value well, even after years of regular use. Today's Bernina embroidery machines, such as the Bernina Bernette Deco 600, are computerised, and files can be transferred between machines by USB ports. Although they're reliable machines, occasionally owners need to do some troubleshooting.

When having problems transferring files between machines, open your embroidery design in the machine's software. Use the "Open File" button on the button panel to the right of the computer screen. Make any desired changes in the design, and then save your design as an ART image file. That way it will be available in case you want to make changes to it later. Touch the "Write to Machine" icon, and then press "OK." Save the design on a removable USB memory stick, and wait until you see the message that says, "Design Successfully Sent to the Embroidery System." Once you see this message, you can remove the USB stick and transfer the file to another Bernina Bernette machine.
If you find that your Bernette Deco 600 is not picking up the bobbin thread, you need to retime the machine. In the machine's lower mechanism, where the bobbin is, there is a timing screw that can be adjusted. Use a small screwdriver to adjust the timing screw. If you turn it to the right, the tension will tighten. If you turn it to the left, it will loosen. Adjust it slightly in one direction or the other and recheck to see if the machine starts to pick up the bobbin thread. Make slight adjustments until the bobbin thread catches.
If your Bernina Bernette Deco 600 makes loud noises after a stitch, the tension probably needs to be adjusted. You can adjust the upper tension mechanism or the lower tension mechanism. Start by reducing the upper tension a little at a time until the noises cease. Use the tension dial on the top of the machine to experiment with the tension. You may have to try adjusting it in both directions until the machine runs smoothly. This solution should also keep the bobbin thread from showing through on the top of the fabric.
If your embroidery shows loose, looped stitches, your bottom tension is probably loose. Put a new needle in your machine by loosening the small bolt that holds the needle in place. When the old needle slips out, insert the new needle and tighten it into place with the small bolt. Next, check the bobbin. The bobbin should turn clockwise as you stitch. Find the small screw on the bobbin case. Use a very small flathead screwdriver (your machine probably came with a special screwdriver that is just the right size), and turn the screw 1/4 turn to the right at a time until the looped stitches disappear.
If the tension screw continues to come loose and cause unsightly stitches, brush a little clear nail polish over the tension screw to hold it in place after the correct tension is set. If you need to adjust the tension later, you can use nail polish remover to remove the nail polish and adjust the screw.
