UPDATE:
OK, this is really crazy

I'm at work right now, so my wife took it upon herself to try to help get my mixer fixed. She just called me a few minutes ago and told me what happened:
First she called the Kodiak Health Company, the place in the US from which we purchased our DLX, to see what they could do for us. They said to contact Electrolux. So she did. Electrolux told her there is ONE service centre for the DLX in ALL OF NORTH AMERICA! And that is in New Jersey. And it's a single person--a Mr. Ross.
So my wife dutifully calls Mr. Ross. It rings a few times, and then a lady picks up and says, "Hello?" My wife, uncertainly, says, "Errr....is Mr. Ross there?" "Who's calling?" the person wants to know.
My wife explains the situation. The person says "hang on a sec" and puts her on hold. A minute or so later, Mr. Ross comes on the phone. My wife explains the problem with the DLX--and guess what? He knows exactly what the problem is. It's apparently something he sees all the time. Apparently, there's some sort of bracket that holds the motor in place, and in shipping, it can sometimes get bent.
"No problem," he says. "Is there anyone handy in your house?"
"Ummm...I guess my husband and I are both fairly handy?" my wife says.
"Okay...fax me your contact info, and I'll send you a replacement part. When you get it in the mail, give me a call, and I'll walk you through the replacement steps."
"But what if we break it or something?" my wife asks, thinking we'd be voiding the warranty or creating more problems if that happens.
"Don't worry, it's not that hard."
Is this wild or what? I mean, I'm overjoyed at the prospect of NOT having to send my mixer back and forth at great expense and with inevitable delays...but this has got to be the strangest "warranty experience" I've ever had!

It's a little freaky to think that there's one guy in the whole continent who fixes Electrolux mixers!
