Kitchen Aid Classic mixer

You may need to adjust the head height if the new flat paddle is a bit bigger than the original. When you have the head lifted up with beater out of the bowl you will see a single slotted screw where the head hinges on the pedestal. Anti clockwise to lift the head up, clockwise to drop the head lower. Paddle should just clear the bowl with head down & motor running.

Very much the symptom of a worm (follower) gear needing replacement. Three are videos of this posted on the net and you can find the Service Manual at:

One thing many KitchenAid mixer owners complain about is that it's difficult to scrape the bowl while the mixer is running. Because the beater rotates around the inside of the bowl, and because the beater doesn't actually touch the bowl, you have to stop the mixer frequently to scrape the sides of the bowl to make sure all the ingredients are well incorporated.

Two companies have come up with fixes for that problem -- the BeaterBlade+ and the SideSwipe.

They are available for most KA mixers. Cook's Magazine tested both in January 2009 and liked the SideSwipe a tad more than the BeaterBlade because they thought it performed a little better on a particularly heavy cookie dough, but one reviewer on another forum commented that dough tends to bunch up on the SideSwipe's inner parts.

In any case, I have the BeaterBlade+, mainly because it was available from Amazon for $30, no tax, free shipping, and I didn't feel like driving around to find the other.

Both are made of very strong plastic and have silicone scrapers on the edges of the blades. The scrapers do touch the bowl and thus provide a constant scraping of the ingredients, assuring that everything gets mixed in. I've found that I rarely have to stop the mixer, except to make sure that the ingredients that cling to the beater itself are mixed in.

This sounds like an issue of beater to bowl adjustment, which can come out of alignment naturally over time and with use of the machine.

If the flat beater is striking the bottom of your bowl, this may cause the locking mechanism to loosen and may cause the mixing head to "bounce" during use.
