I cleaned my machine and now the upper threat won't pick up…

I hope I was able to answer your question. If you would like to ask me another question in the future, you can add me as a favorite expert. You can do that on your "My Questions" page if you choose to rate our interaction, or you can request me by name if you wish.

I am sorry you missed the information I sent. Here it is again. 

Your sewing machine may not pick up the bobbin thread for several reasons.

• The bobbin case may not be seated correctly, or the bobbin is not placed in the case in the correct direction.

• The bobbin tension may not be in an operational setting. Try adjusting the tension.

• Confirming your threading has been done correctly may be necessary. https://youtu.be/wxH2a5qmKL8

• Replacing a worn needle may be the solution to the problem. Also, check that the needle is the right one for the job. Sizing the needle may be necessary for the fabric you are using.

• Cleaning and maintaining your machine is important. Removing the needle plate, lubrication components, and thread debris may be needed.

If none of these solutions work, it may be time to arrange for servicing and timing adjustment.

Our service is advice only.

You would have to contact a local repair service.

I am only familiar with my area, so I would only be googling it and blindly recommending someone.
