E1 Error
Zigzag motor error
Check/Repair
The E1 Error code appears when the needle bar is up and the sewing machine can't prepare the zigzag motor to start. Unplug the sewing machine and check the wiring connections on the zigzag motor and circuit board A. Replace the fuse on circuit board A if the fuse is blown. Replace circuit board A if it has a burned spot. Replace the zigzag motor if the fuse blows and circuit board A is okay.
Possible parts
Fuse, circuit board A, zigzag motor

You should make sure it is grounded. Also, is it getting oil from the pan? Blown fuses usually mean there is an overload in the motor. Check that the belt is not too tight.
Normally that means your main board is blown. Average cost close to $300. If you are feeling high tech you can pull it out and try to re solder all the connections, but boards going out is a pretty normal thing. That machine sells on eBay for $100. Shop rate at most repair shops is $70 per hour. You will do better with another machine.
Likely the problem is a blown fuse in the S-Print (power supply).
You must have a grounding wrist strap when working with a Bernina Activa. They are extremely sensitive and can easily destroy the main circuit board if you don't use a wrist strap. You can get one at Radio Shack for less than $5.
The power supply is the square 1/3 of the machine on the back on the handwheel side.
You can remove the power supply by removing the long torx screw on the rear of the machine and tilting out enough to unplug the connector.
Then dismantle the power supply until you can get to the fuse. Test the fuse with a continuity tester. If the fuse is blown, buy an exact fuse. Don not deviate.
If the fuse is not blown, you may need a new power supply.
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.
There is a fuse in the the base plate
that has probably blown. It is soldered in and needs to be fixed by a Pfaff dealer on someone with access to the fuse. If you have the work done, make sure they replace a certain reisitor on the base plate at the same time to prevent this from happening again (per Paff). Sorry for the inconvenience, hope you are back to enjoying your Pfaff machine real soon.
If this is an older model, the power supply module is a little sensitive to mains spikes - I've had three that have suffered a similar fate and all have required replacement power-supplies - the switching transistor gets blown and this is a job only for the qualified service engineer. My suggestion, I'm afraid, is to have it checked-over by a service engineer. There is a glass fuse on the circuit board, but if blown, it's usually for a reason and 9 times out of 10, just replacing it results in a second blown fuse !!!
the transformer has broken solder connections between the pins for the plug and the transformer board. Brave? 4 phillips screw. Black box on bottom. remove ribllon cable. Transformer out. 2 screws black cover on transformer off. Theres the board with broken solder joints to the plug pins. The large plug they used on that model broke the solder joint easily. it shoudlnt be blowing fuses though unless he tried to fix it and put in wrong one.
