During sewing, the upper part of the stitches on the fabric is fine, but on the bottom, the stitches goes on top of each other which forms a loop. How do I fix this?

Unfortunately, this is most likely a computer board issue and there's just no way to predict if/when a board will go bad.

Your only option at this point is to take it to an authorized Pfaff dealer. If the person who serviced it was an authorized Pfaff tech, take it back to them. If not, do take it to a Pfaff dealer - non-Pfaff authorized techs are not trained on the machines.

Sorry I can't give you a simpler answer, but until this is corrected, your machine won't work properly.

Best,

This is a top tension issue, you need to check two things,

-make sure you thread the machine with the pressure foot up ( this allows the tension discs to open up so you can pull the fabric away from the machine with the foot up and allows the thread to get to bottom of the tension discs)

-make sure your tension settings are set to the medium setting. (Usually 4 or 5)

If this still does not help, then turn the top tension knob up (from 5 to 6,7,8,9....)

-If that still doesn't do it, your probably need the tensions reset, and your local family sewing store will be able to assist you further.

This sounds like a needle problem, put in a new needle and make sure it is the right system and size for your machine.

Bobbin thread being too loose is due to two possible factors. The upper thread may be too loose allowing the bobbin thread to pull it under the fabric, or the upper thread may be too tight in which the bobbin thread will pull up to the top. Try adjusting the top tension to see if you can correct it. If it doesn't fix the problem, take out the bobbin and look for a screw on the bobbin case. If your bobbin case comes out from the underside of your machine, the screw is on the side. If yours is a drop in bobbin, it will usually be under the faceplate so you might have to take that off too to get to it. Turn the screw clockwise to tighten the bobbin, counterclockwise to loosen it. Only go a quarter of a turn at a time so you won't overshoot the mark.Then try by re-threading and sewing. The basic procedure for threading is as follows:---------- Note that Pfaff sewing machines thread from left to right, not right to left like other sewing machines. The upper tension discs should be raised at their highest position while threading, and the presser foot should be raised up until you thread the needle. Drop the presser foot right before you thread the needle. The prevents thread problems during use.-------------
