Bobin thread is loose

SOURCE: Problem with winding thread onto

first you must make sure the winder shaft is turning by moving it to the right a little and see if you can turn it by hand.
If it is turning ok then there is a rubber ring on the other end of the winder shaft and it should come in contact with the drive which turnes it ,if it is worn it might need a new rubber.

Try changing your needle.

SOURCE: how to stop bobin thread from knotting

When loading the bobbin there is most likely not enough tension on the thread letting it overlap incorrectly. Try wrapping thread around a tensioner when filling and that should help. That way the bobbin is rolled as tight as the tension on the upper thread when sewing.

SOURCE: Bobin winder won't wind

I bought a second hand Brother SE-270D. The previous owner had not used the machine in a very long time and could barely remember how to load the cassette to show me that the machine actually worked; but it is in beautiful condition!!

When I tried to run the bobbin winder at home, the winder would not turn, but the motor made a high pitch winding noise! I took it to a sewing machine repair shop and was told that it was because a rubber ring inside the machine, below the winder pin, had deteriorated after years of non use.

The replacement ring and minimal labor cost me less than $10! (The repair person encountered an E1 error message after reassembling my machine, but he was able to correct that by reattaching the wire connections.)

SOURCE: how to thread the bobin on a elna air electronic

I assume you mean when you wind a bobbin full of thread??

You take the end of thread from your spool through the tension device or an eyelet on top of the machine, then back to the bobbin on the bobbin winder and thread the loose end through a top hole on the bobbin. Click the bobbin in against the stop and press on the pressure foot to start to wind. Hold the top thread for a bit as the bobbin starts to fill and then once it has been covered by a row or two of thread, stop and cut of the loose end from top of the bobbin. Now continue to wind the bobbin until it cuts out as it fills against the stopper. Nudge the thread with a finger tip as it spools onto the bobbin to help get the bobbin filled top and bottom and not just in the middle. (bit like when you coil the garden hose onto the reel, it always wants to go in the middile only and then jams up LOL).

Also a really good idea to place your scissors handle into the top of the thread spool to slow/control it as the thread reels off it. This helps give an even tension on the thread going onto the bobbin which really helps with stitch quality later.
