Hello my fello long islander. Sandy was a nasty piece of work! I am sorry for what you are going through, I really am. Now, somebody suggested letting the motherboard dry and see what happens. Electronics and sea water do not mix well, but it is worth a shot.. My hubby is a techie whose workplace was completely flooded and they have to chuck everything. He thinks once dried, your motherboard may work for a short time.That being said, do not chuck your machine. He says to clean and dry all mechanical parts and give a good shot of oil to all parts that need it and can rust. Even if the machine does not work You can use other parts from it that are not electrical. Also, your machine should come under household items protected by the insurance. Fingers crossed. I have a cheapo Singer which sews anything it is one of those heavy duty mechanical machines. Good luck with everything, and I am so sorry for all you are going through.
