I've had this same problem with my Husky. For me it was the connection between the machine and the foot pedal. The plug wasn't sitting properly in the socket. Try holding the plug securely in the socket when pushing the foot pedal. Gently wiggle the plug to see if there is a spot where it will work. I ended up wrapping one layer of electrical tape around the plug, and haven't had that issue since. It could also be the foot pedal itself. If you have another foot pedal with the same plug, try it too. I hope this helps, good luck, have a great day.

This is not a DIY problem. Sorry. Consider the possible alternative causes: broken reverse assembly, stuck reverse button, dirty dogs (stop laughing), computer board problem. Here are some prior looks at this problem:

Other than cleaning the dogs or tightening a few screws, the other tasks require an expensive service manual from the outset, tools, and possibly parts. Note the complexity of a disassembly process of an earlier model :

The ordinary user manual does not seem to troubleshoot (page 45) the problem:

Turn it off then back on. If it is still in service mode something is wrong - take it back to your dealer.

The problem is that of a stuck piston detent on the pattern selector support that snaps the top cover closed.
  1. Open the light cover
  2. Apply pressure with thumbs on the bottom edge of the top cover on both the right and left sides of the cover. The cover should pop up...Too much pressure on the left side, (if this thing is really stuck) and you might break the top cover at the thread tension slot. Be careful here....
  3. Add a drop of acetone (fingernail polish remover) to the piston detent and work it free by pushing it back and forth. Avoid getting any acetone on the painted surfaces of the machine.
  4. Continue to work free, repeating with a few drops of acetone, and wipe clean. Don't oil this part. It was a petroleum product combined with a galvanic process (aluminum and steel) that caused the problem in the first place, not to mention age.
  5. Use DTE Heavy Medium oil rather than a white or clear oil when you lubricate your machine. White oils are unstable and will oxidize (decay) much more quickly. Also avoid 3 in 1 oil and stuff like WD40....very bad....
  6. Oil 1/2 a drop on those prescribed areas. Too much oil is more harmful than not enough....
  7. Contact your Bernina dealer for this oil.

Usually, if the thread is messing up under the fabric, it is a top thread issue. This is sometimes referred to as thread nesting or bird nesting.

Make sure you are using a brand new needle of the type specifically for embroidery. The eye needs to be large enough to easily accommodate the thread size and it needs to be a sharp needle. It may help to use a needle with a larger scarf that will protect the upper thread when piercing the fabric. If the thread is not protected sometimes it will hang up on the underside of the fabric when the needle withdraws from the fabric, causing thread loops, etc.

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. (This releases the tension disk so the thread seats completely.) Verify the thread path is correct.

Use a bobbin thread that is compatible with the embroidery thread. Check that the bobbin thread is smoothly wound on the bobbin, that the bobbin is turning the correct direction in the bobbin case, and the bobbin case tension is threaded properly.

Retest your embroidery on a small project. If you are still seeing thread bunching up under the fabric, you need to tighten the upper tension.
