Question about Sewing Machines
Is the thread in the bob in wound tight enough?
Posted on Feb 22, 2019
Likely top thread tension is too low (or none) or top thread is being caught by debris in hook race. Remove and clean bobbin area (hook race). Could also be a damaged bobbin case. Check top thread tension by comparing foot up to foot down while pulling top thread.

SOURCE: Bobbin thread bunching
I have a Kenmore 16231 That kept bunching up on the bottom side of the material. I found to correct this problem, there is a tension adjustment under the cover on the left side of the machine ( the light is housed under this cover) I found a tensiner lever numbered 1 - 4 and if you try this adjustment on 3 or 4 this machine works great. hope this helps

I don't know if this is the right answer for any of you, but thought I'd put my 2 cents worth in. Often this can be the bobbin in backwards. It needs to unwind a certain way depending on the machine. I've heard a phrase for this: Mind your p's and q's which means some wind off to the right like a q, others to the left like a p. Mine has to unwind one way then be slipped backwards into a little slot or it does that loose bottom thread looping and bunching someone here mentioned. It seems everytime I get that problem I rethread the top thread 100 times before it clicks again and I remember it could be the bobbin thread. Either your manual will tell you the correct way, or you could experiment and try one or the other. Once you figure out whether you're a p or a q, mark it on your machien somewhere to remind yourself.
Good Luck and Happy Sewing!

it had nothing to do with the shuttle, it is the upper thread is not in the tensioner. lift the presser foot up and thread the machine even if you have to hold the thread on the top and pull on the bottom to make it go in the tensioner it will help, if a machine loops on the bottom it is the upper tension if it loops on the top it is the lower tension
