My brother pe150 embroidery machine does not pick up bottom thread and wont sew

try changing the needle
clean under the needle plate & in the bobbin area for loose threads or lint
rethread the machine top & bobbin

Full details on how to adjust the timing appear here in my Brother PE150 blog. You will need a few basic tools including the stubby screwdriver that came with your machine.

Hi. This may sound silly, but the most likely reason the upper thread doesn't pick up the bobbin thread is that the needle is in backwards. (Sounds silly, but it's true!)

Needle shanks have a flat side and that flat side has to go in a particular way for your machine. With most modern machines, the flat side goes to the rear, facing away from you. Check your manual to be sure.

The second most likely reason is that your needle may be bent. Check that your needle is straight (or just use a new one).

Hope this helps!


Happy Sewing,

Robbie

your tension release unit is stuck or slipped out

Two places you can check. The first is Ron at a1sewingmachine.com or Wendy at [email protected].

It sounds like the timing is off and needs an authorized repairman.

No, I did not find a solution. And I have no desire to subscribe to your plan, thanks anyway. It is still a PE150 not LS-2125.

Make sure that your needle is put in the correct way, there is a groove in the front of the needle, check with your finger nail, this is usually to be facing you, and make sure the thread is going through the tension holder correctly do not have the foot down when you are threading the machine,as this stops the thread from going through the needle tension holder.

If you tighten up your needle thread, reduce the tension of the needle thread.
For embroidery, and zig-zag, and because the needle makes side movements, it needs more needle thread.
So try to keep you needle thread not very tight,
and tight up your bobbin case tension more, so that the two threads meet under the meterial.

You need to adjust your top tension and maybe your bottom tension ( the little screw on the bobbin cover) Also check your needle and make sure it's straight.
