The front panel circuit board has a microswitch which is activated mechanically when the bobbinwinder is moved to the winding position. The error is most likely with the microswitch stuck in one position. The remedy requires you to have moderate mechanical aptitude. The best thing to do would be to take it to your dealer for repair. If you want to try to do it yourself, here you go:

  • DO NOT REMOVE THE SCREW HOLDING THE SMALL PLASTIC BOBBINWINDER STOP NEXT TO THE BOBBINWINDER SPINDLE
  • Open the top lid and, with a straight slotted screwdriver, remove the two large silver screws
  • Close the lid and raise the handle into the carry position
  • Loosen, but don't remove, the small phillips screw underneath where the right side of the handle rests
  • Pull the top of the right side cover over slightly
  • Remove the small phillips screw underneath where the left side of the handle rests
  • With the handle up in the carry position and the lid closed, lift the entire top cover from the left side first, exposing where the handle attaches underneath
  • Carefully bend the lower part of the handle to the right and detach it from its mount
  • Remove the top cover and handle
  • With the top cover removed, you can see the bobbinwinder arm make contact with the microswitch
  • If you are extremely careful to not touch the circuit board with your bare fingers or with a metal object, you can manually press the microswitch to see if it works
  • The plastic microswitch "button" may have become detached
  • The "spring" on the end of the bobbinwinder arm may have become bent
  • Don't remove the bobbinwinder assembly

Digital display shows bobbin wind. Bobbin wind spindle moves slightly. When depress foot pedal, stitches for only a minute- stops. Cannot select any stitches as menu display remains on bobbin wind.


try putting a bobbin on to wind and then take off again, make sure when you do that the bobbin holder clicks back into the sewing position not the winding, you might need to give it a little push in the right direction then see if it sews ok for you. if not may need a service call.

Just wound a new bobbin. When finished winding, I cannot get it off the winding spindle. I'm using the bobbins that came with the machine.


I'm using the bobbins that came with the machine. I moved the winding lever back to the right. It should just lift off, but it will not budge.

I just inherited another Huqvarna (this is a model 630). It was working great until I wound a bobbin on it. After I removed the filled bobbin the machine won't move the needle up and down (but the bobbin...


I do not know the Husqvarna Viking 630. However, I have used the Viking 6690 and it has a similar on-the-side bobbin winding routine. I suspect that you failed to move the bobbin winding mechanism back into the sewing position. Look closely at the area around the bobbin winding spindle. It looks like there is a lever below the spindle. Does this need to be moved or rotated? Double check the steps in the manual and check that you did the opposite steps of preparing to wind the bobbin.

On the 6690, you pull out a knob after removing the bobbin. (You push this piece in and put the bobbin onto the now exposed spindle for winding.)

I hope this helps.

Singer 362 bobbin


It appears from the manual (see pages 9-10, which are on 11-12 of the pdf version) that it is necessary to disengage the hand wheel (loosen the center knob) with the bobbin winding lever all the way to the left, before putting the bobbin on the winder spindle. Put the bobbin on the spindle, then set the winding lever to the right position to engage the spindle drive. Do not tighten the hand wheel knob until after the bobbin is wound and the lever is moved back the left to permit bobbin removal.

If you are following these directions exactly, or you can't get the hand wheel knob loose, you have a mechanical problem to solve. You may need a stronger hand to loosen the knob, or something in the bobbin winder is bent, out of adjustment, or jammed with foreign material. If you are mechanically inclined, you may want to remove the top cover of the machine for inspection.

I have a Freesia 425 - I have wound the bobbin successfully, but the bobbin will not come off the winder - any explanations


The bobbin is probably cracked. They get that way when bobbins are wound in correctly, or to tight. Just break it off and get new bobbins. Just make sure your theading it correctly when winding bobbins.

My bobbins sometimes don't wind right. The thread gets all tangled at the bottom of the bobbin instead of winding evenly. I'm sure it's user error because sometimes it works. Hoping you can help me figure...


when the thread is on the spool pin
1.guide the thread around the bobbin winder thread guide
2.insert the thread through the hole on the bobbin, threading from the inside to the outside
put the the bobbin spindle
3.push the bobbin winder spindle to the right (if you have a electronic machine the LED display
will show SP)
4.depress the foot control, when the bobbin is fully wound, stop it, & push the bobbin spindle to the left, cut the thread & remove it from the spindle

Bobin stuck on the bobin winding part. will not come off when bobin winding is disengaged or engaged. Tried turning machine off and on. still will not come off. have looked for thread that might have...


Sometimes, depending on the thread, the bobbin winds too fast and the plastic expands with the heat. That's why you can't get it off. There's two ways you can get the bobbin off. Leave your machine turned off before trying either one! Unwind the bobbin of all its thread and maybe, just maybe it will shrink back to normal size once it is cooled and you can slip it off. If this doesn't work, there's nothing for it but you will have to break the bobbin off. Get some pliers and break it off in small pieces taking care not to get any broken off bits inside the machine. It's actually easier to do than it sounds (ask me how I know LOL!). You also need to be very careful not to yank the bobbin off and pull the bobbin spindle out of position. If you do end up doing this accidentally, you may be able to gently push it back but don't doing anything with great force - easy does it!
In future, you should wind all bobbins at reduced speed - bring the speed down at least two clicks. You get a more evenly wound bobbin this way also. And invest in more bobbins. They are relatively cheap and you can wind up quite a few at a time before starting a project.

I wound a new bobbin and now I can't get it on the bobbin winding spindle. I have the exact same problem with a husqvarna 400


When you wind a bobbin on a Husqvarna and you leave the machine threaded to wind the bobbin through the needle, you must take the thread down below the foot (a metal foot only) before you take the thread up to the bobbin winder. If you take the thread directly from the needle it creates too much tension on the thread and crushes the center of the bobbin so that either you can't get the bobbin off the spindle or in some cases it damages the bobbin completely.

Some threads, the kind that can stretch slightly when pulled, shouldn't be wound through the needle at all. Instead go through the first guilde and then straight down to the little metal "button like" guide and then to the bobbin. It will create much less tension on the thread and wind it much better.

Bobbin won't come off the winding spindle


Your bobbin was basically crushed slightly, to remove it simply take the thread off the bobbin and it will come off very easily.

If I understand the problem, the bobin winder has probably lost a rubber 'o' ring.

Unscrew the two top screws and remove the top cover. At the base of the bobin spindle is a metal disk that should have a rubber 'o' ring on it. This will perish over time and break off.

When the bobin winder is pushed sideways into the active position, this should contact the main turning handle thingy (that's a technical term) and be spun around. Check if the bobin 'o' ring is making contact or if it is even there at all. Any sewing machine repair shop (or good automotive store if you're desperate) will have a replacement.
