If you are handy with a soldering iron and are competent to take the circuit board out of the bottom of the machine. You may find that several of the capacitors will have blown or leaked and are no longer working. They can be identified by the discharge near the terminals of the 22uF 25v capacitors. Change these for 22uF 50v ones and this may solve the problem as it did with mine.

Could be motor brushes or a bad base plate board circuit board. That is a great machine but may be hard to find someone to fix this problem. Take to only to a pfaff repair shop. Motor brushes should be around $50-100 repair and base plate could be up to $500. I would also check it with a nother foot control just to be safe.
If your husband wants to do the job here are some tips.
The motor is right behind the display board, you will need to remove the diplay and motor to get to the brushes.
For the base plate board, Remove the 4 large flatblade screws to get the base plate off.
Right next to the trasnformer there 3 small fuses, (they are back and say fuse on them) if one is very carroded and white there is a good chance that is bad and replacing it will fix the probem.
Lots of work for bolth if the repairs and I recomend you take your machine in.

My Pfaff Creative 1475 won't run. The lights are on but when I push the pedal down it doesn't do anything. Please help


there are 2 things it could be
1.the foot pedal could have gone out
2.the motor,,here's how to tell about the motor,, smell the motor & see if it has a smell to it,,if the motor has a smell like old dirty socks or a burn smell then chances are the motor has gone out

the motor would have to be replaced at a repair shop,, the foot pedal you should be able to do your self
