Viking #1+ sewing machine the needle and presser foot bar is loose how can I fix it?

Did you check the needle down button. Be honest and return it. Price one and wonder why you borrowed something so expensive. She may know what to do. But dont tinker or try to fix it. It seems like a fixable error. You probably afraid to tell her. But you stressing yourself out. If you borrow it you probably know a cheap embroidery machine is about $500. Just get it back and maybe she won't snap its probably something simple.

It could be lint jammed into the jack the cord plugs into. Make sure the jack and plug are both clean and free of lint. It also could be a damaged cord. If a friend has a working Viking pedal try borrowing theirs to see if it works on your machine. If not, your machine might need service.

some sewing machines have a screw that you have to undue
other sewing machines have a lever at the back of the foot,that you
push toward the bar that holds the presser foot.

presser foot down???

The Viking Designer 1 has a presser foot sensor system in the head/needle bar area. I believe that you have some thread wrapped around a link in that area. Look closely in the area that the take-up lever is in and if you see a thread end, try to get a hold of it with tweezers and turn the handwheel backwards to see if it unwinds.

Good Luck

Not sure what exactly you need to know. Are you trying to lift the presser foot or change the presser foot to another one? If it is lifting, there will be a lever of some kind behind the machine. On one of my Husqvarna machines it was a big flat "paddle" shaped lever, not sure what shape it is on the Emerald machines. Lift the lever from the bottom upwards and outwards. Most Husqvarna machines have clip on-and-off feet. You just gently pull forwards on the foot (while the presser foot is raised) to remove it, then push the new one on making sure the small bar part of the presser foot goes into the clip on the presser foot ankle.

There is a presser foot pressure dial on the left end of the machine, make sure it is on 3 or higher.

The bobbin spool is loose, the bobbin case is loose or the bobbin stitches are loose??????

If it is the last one - thread the machine with the presser foot up and see if this resolves the issue.

If the lever to lift the presser foot is now just loose, take the face cover off (Left side aound light) and take a look, presser bar may have over extended and fallen off the lever connection...needs to be taken even higher as the lever is eased back and reset to "normal"

Several things could be happening. It may be the hook/needle timing. Or it could be the feeddogs are not moving (that's the toothy looking part under the presser foot that moves the fabric). Recommend removing thread and bobbin (needle and presser foot). Slowly move the handwheel and put your finger on top of the feeddogs to determine if they are moving back and forth and are high enough to move the fabric. Check to make sure you had not manually lowered the feed dogs. You may need to take it to an authorized Husqvarna Viking dealer for their assistance.
