Tension problem & I just got it out of the shop - PE150
I don't use my embroidery machine a lot, but used it at the end of August to monogram something & it was fine. Used it again a couple of weeks ago & it did the picture designs fine, but with letters, the bobbin thread was coming to the top. I adjusted the tension per the book & no matter how much I lowered it, it did exactly the same thing.
I called the sewing machine store where I bought it & the guy there said there could be a thread under the bobbin that I couldn't get to. So I took it in & the guy said he would call with an estimate when he looked at it. He called & said he didn't see anything so it probably needed servicing where they take it apart, clean it & all that. I told him it probably didn't really need servicing because it only had 10-12 hours use on it. But he said that's all it could be. So, ok I said.
He called when it was done (about an hour later) and said since it didn't have much use on it, he would only charge me 1/2 of the regular service fee of $75. I picked it up & it had a piece of material in it where they had done a design & a word in light green thread. When I got home I looked closely at the word, I thought I could see the white bobbin thread on the edges. So I got my magnifying glass out & it wasn't bad, but it was there. So I got out navy blue thread & did the same cursive font I tried to do when it was messing up, and it was still messing up. Any suggestions before I take it back in again?
