Question about Singer 7422
Hi - my thread is getting all knotted up in the bottom area around the bobbin casing. Any suggestions?
Mine is also doing this, but it has an auto tension and doesn't have those numbers on it. It is the 7422 Advance. I just bought this machine and have yet to be able to do anything with it. Very disappointed. Taking it back ASAP and never buying Singer again. Machine locks up for nothing, have to turn off and back on and it works, then the thread bunches up at bobbin and I have checked everything. And it was suppose to be able to accomodate a little bulk, (doing a quilted christmas stocking), however the fabric will not feed and it just starts to bunch up. Good luck

What you have going on is probably a bobbin problem. The knots are referred to as birds' nests and happen usually happen when your bobbin thread gets caught on something in the bobbin area. To be certain it's a bobbin problem, change your needle. Even if the needle looks fine, it could be just slightly bent and still look fine to the naked eye. If that doesn't solve the problem, take the fabric out of the sewing machine and turn the machine wheel by hand. Watch what happens thru the plastic window in the bobbin area, or if you don't have a plastic window leave the bobbin covering off. Is the thread catching somewhere and causing a bunch of thread to gather in the bobbin area? Be very careful when investigating in the bobbin casing/area-it's easy to chip things in there! Often times, a piece of something falls in there and can be pulled out with tweezers. Just as often, the bobbin casing is slightly tilted and needs to be straightened or has a chip in it and needs to be replaced. You can normally get a replacement on eBay, searching with your machine model number. Also, check out SewVacUSA. If you need help replacing the bobbin casing (it's easy, you just need to be careful), or if these solutions don't work, leave me a comment. I check back daily, so I'll get back to you within 24 hours normally. Leave me as much detail as possible and I'll do everything I can to help you!
