I bought a brand new KitchenAid Professional 6500 from "kitchenaid.com" just a week ago and set it up today, I used the flap beater attachment to make cookie dough.
When mixing butter with sugar and eggs until it creams, no clicking noise can be heard.
But when adding 3 cups of flour to the mixture, clicking noise can be heard.
All of the above was done at speed: "stir".
I do not like this annoying clicking noise for a $500 mixer, completely absurd. Had I knew about this "normal, common, not-a-big-deal" problem among the KitchenAid mixers (specially in the "professional" series) I would've originally spent $700 for a Bosch or an Ankarsrum mixer.
What exactly is causing this clicking noise when under light load such as cookie dough? Is it the gears or the retaining pin bumping with the attachment connector? Thinking to return this...
Thanks!
