I have a PE-150 and am pretty new at learning all about how to use it, but one mistake I made was purchasing some pre-wound bobbins from eBay and receiving the wrong size. It took me a little time to realize they were just slightly taller than the ones that came with the machine. Once I got the proper size in, the bobbin worked fine. This may not have anything to do with your problem, but I thought I would mention it just in case! Good luck.

My PE 150 is very picky about the weight of bobbin thread. As long as I used Coats & Clark 70 wt. I was fine. Even Brother's 90 wt. thread wasn't compatible. Check your bobbin casing very closely for a tiny bit of thread that might be caught in there. That happened to me and once I got it removed, the machine worked great.

Also as Tangle mentioned, you must use the correct size bobbins. Hope we helped!

You are both correct. We have had this machine for about 5 years. We too have been through all the wrong thread size, bobbin size ect over the past few years but this is obvious to the eye. When the pickup comes around to grab the thread the needle is up not down. This is the first hickup and believe me it has had some emb. ran through it. I find it interesting that even Brother will not tell you how to time this machine. It is no different from a car, same principle. The gear on the bottom of the bobbin has teeth and a belt. it has obviously jumped a tooth. It has timing marks somewhere and there are instructions somewhere. Everyone wants money. Money, money money. I am retired and capable of fixing this machine as I repair everything. When I find out I will post it that is for sure.

Thanks

I'm new to embroidery,and have just brought a brother pe-150,and thought i'd got a bargain,I've done everything,cleaned,changed needles,rethread it about 50 times,but my top thread will not pick up bottom thread,from everything I've read I'm thinking it may be the timing,not sure how to go about fixing this,looked in the manual and looked all online,don't understand it,feeling very frustrated and very disappointed,can anyone help?

I have a repair manual and part manual
