Did your Kitchenaid (600 series) make an odd noise at first?
We received a Kitchenaid mixer 600 series 6qt mixer as a wedding gift. We have used a few times and we have have noticed that the motor makes a very odd metallic whine sound. After a few minutes of use this does stop and the mixer performs as expected, or at least to my knowledge. There is also an odd odor at first use, which I have researched and found to be normal and will eventually go away...
But, what about this sound? Do I have a dud? Or, a future dud?
i don't recall any noise like that when we got ours.the only issue we had was to have the switch replaced just after the warranty expired.apparently it was a common problem which had been resolved.otherwise,i can't think of anything.i'd say keep and eye ( or ear ) on it for now,especially while it's under warranty.
I bought the 600 a few years ago and had to exchange it with the manufacturer. I don't remember exactly what was wrong, but in addition to not working well it made a horrible loud noise. They sent me a new one right away that not only worked perfectly, but was quieter. It still makes a loud noise, but not nearly as bad as the first one.
I think you should call KitchenAid and get it replaced.
I had to send my first one back when it just stopped working and found Kitchenaid to be very helpful and it was quickly replaced. If it doesn't seen right, I'd suggest that you contact them and see about replacing. By the way - thanks to another chowhound thread, I got a smaller bowl with it's own attachment that fits the 6 quart and is great for small recipes, whipping cream, etc - makes the machine much more versatile. Williams Sonoma was the only source when I bought it last year.
