Singer 7422 bobbin thread bunching up

hi Sue.
Why does my bobbin thread keep bunching up? Check Your Tension Settings. Looping underneath the fabric usually occurs when there is not enough tension in the needle thread to pull the bobbin thread. Sometimes thread bunching can be caused by something as simple as the tension dial being inadvertently turned.

Put in a new needle. Unthread the machine then rethread it being sure it is threaded correctly--especially through the tension control. Remove the bobbin and make sure it is wound correctly. Replace the bobbin and being certain that it is in the correct position. Check the manual if you are unsure how your machine is threaded or how to replace the needle.

upper part of machine not threaded correctly. no needle tension = bunching underneath

Make sure you have the machine threaded for the bobbin and not threaded through the sewing path. Also, check to make sure that the bobbin is pushed directly against the post as far as possible.

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
