Fabric to thick. Bent needle none of theses are the problem but machine still won't go

That is the wierdest error message I've ever seen on a sewing machine. Did you try a brand new needle? Are you sewing thick fabric (does the message appear when sewing light-weight fabric? Remove the bobbin case from the machine and check for thread wrapped somewhere. If you are not able to find an answer on your own, then it's probably best to take it for service.

On what

Try a brand new needle. A dull or bent needle will frequently not pick up bobbin thread. Also, be sure you are using a needle type that is suitable for the thread and fabric you are sewing, ie if you are sewing woven fabric, use a sharp needle, not a ball point or jersey needle.

If you are still experiencing problems, it could be a timing issue. Take it for service.

Sounds like a belt slipped.

it is possible that the computer part of the sewing machine is going out
when was the last time it was serviced

have you checked the needle to make sure it's in correctly--flat side of needle goes to the back of the machine

correct needle insertion is mandatory for the proper use in your sewing machine. Raise the needle bar to the highest point, then loosen the needle clamp screw to remove the old needle.
place the new needle in the needle clamp with the flat side of the needle facing the back (or if using a round needle the groove in the needle should be facing away from the shaft.
push the needle all the way up to the stop, or as far as it will go, then tighten the needle clamp screw.

how to decide which needle is correct to sew with, it depends on the fabric & thread being used for the project.
like for example, I've been sewing for over 30 years, I'm sewing a stretchy fabric & regular needles won't work because they skip stitches & will pull the fabric thus damaging the fabric, the needle I have to use is a singer universal ball point needles, & I have no problem with the stitches they come out fine.

have you tried using a new needle- if the needle is the slightest bet bent or or damaged it can cause problem with the fabric threads

if the needle is not the correct one for the fabric, it can move or damage the fabric threads

also clean under the needle plate for loose threads or lint also in the bobbin area

try a
Jean-a-ma-jig or Hump-jumper
trying to sew over a bump of fabric, such as a thick jean hem, try using this tool
local fabric store should carry it
It keeps your pressure foot level as you sew over the
bump
you said your needle plate has many strike marks on it,,make sure you can't feel the strike marks so the fabric won't hang on them,,because marks on a needle plate can pulled the fabric

make sure the machine is threaded according to the operations manual & the tension adjustment is according to the operations manual says
make sure the needle is not bent, and also the correct needle for the machine & fabric
if none of these work it needs to be taken in to be check

Hello,
The first thing to try is to decrease the upper thread tension as it may be too tight. You also may need to increase your bobbin tension. Another possibility is that your machine may need to be re-threaded in case it's not threaded correctly.If none of these solutions work, you may have to change the needle as it may be bent. Also, make sure your needle is the right one for this type of fabric and thread.

I hope this helps.
