more brain fade .. last one...
you may have one of two different styles of bobbin case in the
7000/8000/9000 lines !!!
apparently there was some bobbin case escapement upgrade ??????
anyways page 60 of your 7000 manual gives very good instructions
on how to adjust the lower thread tension of your machine. An
adjusment screw/knob with a +/- and arrow that is turned to
adjust.
If this tension adjusment has no affect then you may need to
calibrate the tension as described in a previous post. I
described the one style bobbin case previously. On the other
style of bobbin case (the one with the +/- arrow screw)there is a
*hex set screw* very close to the (+/- arrow screw) it is used
to adjust the median or baseline tension setting.
you will have to decide which style of bobbin case is installed.
sorry for the confusion, i have several service manuals for the
7000/8000/9000 some combine the service info for all models into
one manual and you have to read all the notes to figure out what
you are suppose to do ....

Penny,
thread your machine with 2 different colours top and bottom - now sew.
Is it the top thread lopping and irregular on the bottom of your fabric?
Or the bobbin thread?
Loops & tangles & irregular stitches on the underside is usually caused
by poor *TOP* tension.
So, give your machine a good clean out, floss the top tension discs, put
in a new needle, and see what happens when you try again. Putting 2
different colours in really helps you fault diagnose what is going on
with your machine.
HTH, Sarah

Loops on the bottom but not the top is typically an upper tension problem.
Are you remembering to thread with the presser foot *up* -- this opens the
top tension and allows the thread to enter. Or could you have a dirty top
tension? "Flossing" with a clean, much washed fold of muslin dampened with
rubbing alcohol will often get out some amazing grunge.
Another trick to try is to get out the manual and read each step out loud*
and then do it. *No, I don't know why reading it out loud is better other
than it slows you down a bit and allows the directions to sink in. But
it does seem to help.
