Bobbin case keeps popping out

Check our bobbin for burrs and damage. If the thread catches a rough edge it can pop the bobbin out. Try a different bobbin with new thread... see if that helps. If it does your current bobbin is likely trash.

Hope that helps.

change the thread
put in a new needle--normally flat side goes to the back of the machine
keep a thread tail of both top thread & bobbin of at least 3 to 5 inches & make sure the thread is pulled behind the needle to the back of the machine

You have to make the first stich by hand using the hand wheel and pull the top thread up. It will loop around the bobbin thread and then you can pull it up and lay both threads to the back of the machine before you start to sew.

first start with the needle & see if it's bent-roll the needle on a flat surface & see if it roll correctly
when a needle is blunt it makes a popping sound when it goes thru the fabric
check the bobbin to see if it's warped-I have had some that were
check to see if there is lint or loose thread in the bobbin case area
rethread the machine to make sure the upper thread is not catching on anything
sometimes the thread can come off the thread take up lever
& sometimes it can get caught on the spool pin & also on the notch that's on the thread spool it's self---I've had this happen before
if you sew alot-good maintenance practice is to clean the bobbin case area at least once a week-if you don't sew alot-once a month & also under the needle plate
when cleaning under the needle plate-make sure you do not damage the top of the screws when you remove them to clean under the needle plate & because if the top of screws get damaged they can pull the fabric when the fabric goes over them
check also to make sure your top tension is correct

Definitely needs retiming, I can attach instructions if you email me. [email protected]

I have a Futura CE150 and error 19 keeps popping up but nothing seems to be wrong with the thread or bobbin thread

From what I gather on other sites, your thread has to be threaded under tension.... You have to make sure you hear a click when your bringing your thread down to the bottom of the "arm". Also, I thought the bobbin case was rather loosely held in its place, I adjusted this by unscrewing the black plate and moving it over just a smidge. The bobbin is supposed to have some wiggle room, but it kept popping up and making the tiny adjustment seems to have done the trick....for now...

you may have put the bobbin in wrong so when runnng it pul on the thread which pops the bobbin,
check under the boobin case make sure it clear of dirt and thread, also the piece under the bobbin case may also have been push out of place make sur it is in correct.

Usually when this happens the bobbin is in wrong, replace it make sure the thread is going out the right way, make sure there is no lint or small pieces of thread around or underneath the bobbin area. Make sure you thread it with the foot up. Also make sure you are usng the right bobbin for the machine. They can easy get mxed up.
