Try a new needle, sometimes there is a burr on the needle that is hard for you to see. Make sure that the flat side faces the rear of the machine and is inserted all the way up.

The top thread does not catch the bobbin thread. It worked fine for an hour or so and just in the middle of a design it start having this problem. Please can someone help me?


Be sure to install a brand new needle. Sometimes a bent/damaged needle will not pick up the bobbin thread.

Sounds like the timing could be off on your machine. There are web sites & videos explaining sewing machine timing or you can take it for service.

Bobbin thread is not catching


Try installing a brand new needle verifying with the owner's manual that is installed correctly. Also check that it is the correct type needle for your machine.

Tension generally will not cause the problem of the upper thread not picking up the bobbin thread.

If it is still a problem, the machine could be out of time--the needle and hook are not meeting at the proper time. Take it for service.

Model 140m. Why doesn't the bottom bobbin loop to the needle?


The hook pulls the top thread around the bobbin. Remove the needle plate and turn the hand-wheel toward you while watching the needle. The hook should catch the thread as the needle is on it's way back up. The loop may not form since there is no material or needle plate, but you can see that the needle and hook are in a position for it to happen. This is called "timing".
A simpler answer might be bent needle, wrong needle or needle in backwards, all simple mistakes I have made.
When putting it back together be careful of the black plastic bobbin case as it is often easier to get it out than to get back in correctly.

Twin needle not catching bottom thread


it's probably time to get new twin needles, the point of the left
needle could be slightly damaged.
I would also suggest that the machine be rethreaded top & bobbin
make sure to use every thread guide
clean under the needle plate and in the bobbin area for lint
if buying new needles doesn't solve the problem then the machine
may need to be checked to see if there is a problem with the timing.

Necchi 215A Sewing machine Could anyone help I have a Necchi 215A which will not catch teh bobbin thread, I have tried a new needle and checked the bobbin is loaded and fitted correctly. The needle passes...


Make sure the bobbin has a 3-5 inch thread tail
Then make sure the top thread has a 3-5 inch tail
Then hold the top thread tail with your fingers (away from the needle)
& use the hand wheel on the right hand side of the machine to slowly
Lower the needle in the bobbin area & see if the bobbin thread will pick
Up that way

Viking husqvarna classica 100, thread tension


I suspect you are correctly threading the machine but the timing of the needle and bobbin hook is off. When the threaded needle goes into the bobbin area, a pointed hook grabs the thread and loops it with the bobbin thread. Something is catching when the needle starts to come up that is not allowing the bobbin thread to be pulled back through the needle plate opening by the upper thread. With machine threaded and bobbin in place, have the bobbin area open if possible and watch the thread interaction when the needle goes down. To set the hook/needle timing, normally covers have to be removed. Suggest taking it to an authorized Husqvarna Viking dealer for service. You can find the nearest dealer by click on the "Dealer" link at http://www.husqvarnaviking.com
Good luck.

Thread ball up


Check your bobbin area. Make sure you have put the bobbin in the case with the H logo up and the thread pulls off the spool in a counter clockwise motion. Make sure the bobbin is sitting in the case and threaded through the "catch" on the bobbin case. Then leave a long piece of thread from the bottom, holding the end of the top thread, lower the needle for one revolution using the handwheel. Does the top thread catch the bobbin thread and pull it to the top? This is done without fabric. Your checking to determine if the top thread catches the bobbin thread and pulls it to the top. IIf it does not, it is most likely hook/needle timing. f it does, gently pull on the bobbin thread and determine if it pulls through with a little resistence (checking bobbin tension). Make sure you are using correct needle -- Schmitz or Inspira needles are recommended (Universal size 80 is standard). Make sure you are using Husqvarna Viking made for your machine -- original ones were green but there are some new colored ones but all have the Husqvarna logo on them. Otherwise take it to an authorized Husqvarna Viking dealer. You can find your closest dealer at the Husqvarna Viking website - http://www.husqvarnaviking.com/us Good luck

Bobbin thread won't catch with needle thread


check that the needle is in the right way round i.e. with cut out on the needle facing into the machine. if this is fine then check that as the needle comes back up from the lowest point that it goes to, that the point on the bobbin case passes just above the hole in the needle, i.e. in the middle of the cut out.(if not it needs re timing) if threaded a small loop should appear at this point for the bottom bobbin to catch if not slacken the top thread and try again.

Bobbin help please!


Take out the raceway and check for broken threads/lint. Unthread the machine and put in a new needle taking care to insert it correctly. It may be that the needle is slightly bent. Put everything back carefully and check it is running smoothly with NO THREAD first(no bobbin thread either-use an empty bobbin). This will prove there is nothing catching. If it catches when you thread it then you are having a problem with incorrect threading.
