Machine is sewing along just fine and then makes a wad of thread on the underside and stops sewing. I removed the plates and cleaned out but it is still doing that. Seems to pull the top thread and needle over to the right when this is going on.

Remove the needle. Then, remove the needle plate and try to remove the bobbin case from the machine. Otherwise, very carefully snip thread wads with small scissors and remove the clipped thread pieces with tweezers.

Hello
The description seems to indicate that the top thread has no to very little tension. Try rethreading the upper thread and make double sure that it is engaged in the tension assembly AND goes through the take up lever (that is the little 'thingy' that goes up and down really fast as your are stitching).
Generally loops on the underside are caused by loose thread on the top.
Happy stitching

Sounds like there is fuzz trapped somewhere around the bobbin or race. That often happens when you clean a machine. You may need to take the face plate off and gently remove thread or fabric that might be hung inside. Look carefully in and around the bobbin and race and gently remove any debris you find.Count to 10 and grin.

Needle may be having a hard item getting through a thick wad of fabric -- use a heavier-size needle. Or, threads have bunched up and need to be cut to release the machine. Check the underside of fabric for bunching threads in that case -- and adjust your top tension.

Try these suggestions
1. Change the needle--use a needle that's for the fabric being sewed
2. Rethread the machine--top --make sure to use every thread guide
3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case, & make sure the bobbin is turned the correct way in the bobbin case
4. make sure the thread has not come off the thread take up lever
5. Clean under the needle plate & in the bobbin area for lint or threads

check to see if the needle is damaged
some sewing machines bunch up on the underside when the thread come off the thread take up lever

Yes, it does. There are a couple of reasons the bobbin thread could be bunching up on the underside of the fabric. It could simply be that the machine needs cleaning. Take the bobbin assembly out, brush all the old lint out as best you can, reoil the machine once it's all clean, and make sure there aren't any little bits of thread caught in the bobbin assembly. Rethread the machine (carefully) and change the needle. This solves the problem usually--especially if the machine was sewing along fine and the problem develops suddenly. '
The other thing to check is your tension. It could be that the top tension is too loose. But different color thread in the top and in the bobbin, stitch a few inches (be sure to held the top and bobbin thread ends behind your needle as you start to stitch) and check. WIth the pressure foot down, adjust the tension, and stitch again. Keep stitching, checking, and adjusting until you see little if any bobbin thread on the top or top thread on the bobbin.
Another thing to reminder: use the appropriate thread and needle for the fabric you're sewing.
Let me know if this works, ok?

machine not threaded properly? wadding thread underside means upper thread does not have tension.

Try oiling the hook if you haven't recently.
Check you needle plate and hook for damage, they may need to be buffed or sanded smooth.
Check your upper tension discs for lint and double check your upper thread path (proper threading).
There are other things like hook timing, needle clearance or broken check spring that may be wrong but you need a technician for those things.
best of luck!

Tension!!!! Its all about the tension! I just had this issue after loosening my tension. So tighten it - the higher the number the tighter the tension. My tension is set at 6 on a Singer 9005 and it seems to work great. By turning it down to 4 I ended up with huge loops/wads of string. Hope this helps!
