Message remove thread jam under the stitch plate keeps appearing! It's clean!

Be certain the foot plate is UP

Remove the needle and clean ALL the remnants of thread

Difficult to say without really seeing what's happening and which thread is breaking. If the top thread is breaking, check to make sure the thread is not wrapped around the spool pin or a thread guide.

Just some things to try:
Install a brand new needle.
Be sure to clean and remove all the thread pieces, lint, etc from under the needle plate, around the shuttle, etc. Oil as instructed in the owner's manual.
Remove all the thread from the machine. ALWAYS RAISE the presser foot when threading the top and rethread the machine from the beginning. Check that the thread path is correct and the bobbin is loaded and threaded correctly.

Be sure to use good quality thread--no Old or bargain bin threads!
Solve Most Sewing Machine Problems With These Simple Tips

Why Does My Sewing Machine Keep Jamming Sewing Made Simple

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

try rethreading the machine top and bobbin
try turning the bobbin the opposite direction
clean under the needle plate and in the bobbin area for lint or loose
threads
make sure the top thread has not come off the thread take up lever

try rethreading the machine
change the needle--one that is correct for the fabric
make sure the top thread has not come off the thread take up lever
turn the bobbin the opposite direction
clean under the needle plate and in the bobbin area for lint

Hello

Primary causes of upper thread breakage:


-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.

Tips;

1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

Change needle
Clean under needle plate where feed dogs are for lint
Clean bobbin area for lint or loose threads
Rethread machine top thread make sure to get every thread guide
& bobbin
Check tension 3 or 4 is usually good

change the needle
clean under the needle plate where the feed dogs are for lint
clean the bobbin are for lint or loose threads
check the thread tension-usually 3 or 4 is good
rethread the machine top thread & bobbin
some machines jam when the thread come off the thread take up lever--I have to watch my mechanical sewing machine for that problem

change needle
change your stitch length dial to a number higher like if it on 3 change it to 4 or 5
change the tension to 3 or 4
clean under the needle plate where the feed dog is for lint
clean the bobbin area for lint or loose threads
rethread the machine

change the needle
clean under the needle plate where the feed dogs are for lint
clean in the bobbin area for lint & loose threads
rethread the machine getting every guide
watch to make sure the thread does not come off the thread take up lever
make sure the bobbin is not warped or damaged
