We have the KA Professional model that appears similar to yours. I consider your demonstration load to be Low, certainly not Heavy. DW makes double cookie batches and I make three loaf bread batches. My load is heavy and it creates a strain on the machine so that it shakes the bowl and mixer head and creates plenty of noise. It does not click.

I admit that your click is surprising, but for some reason it doesn't alarm me; it sounds benign. Perhaps someone else has had a failure with such a sound but I certainly don't recall any threads on such a problem and I do casually read about such things.

Mine did and it cracked at the housing after about 3 years
of use. I only used it for wheat bread and it always seem to be under a load. That
was my third Kitchen Aid in about 10 years the first I took back to Costco when
it started leaking oil around the seam in the head after 2 years. The second I gave
to my DD when the new pro came out she rarely uses it so its fine but it did
click under a heavy load. I have the artesian with the glass bowl sitting on
the counter but only use it for cakes, whipped cream and maybe pizza dough I haven’t
made anything heavy in it.

Kitchen Aid customer service wanted me to send the pro back
for repairs but I bought a Magic Mill instead pricy but so far I’m happy with
it although it did have somewhat of a learning curve the first time I used it.

I have KitchenAid® Pro 6500™, which has a 6 quart glass bowl, but is a lift mixer, and it makes no clicking sound. I wonder if the problem is with the 7 quart bowls only.

If you have an electric drill, many of them have at the chuck a dial you can turn to adjust the amount of torque (power) the motor delivers to the load to prevent over-power or stalling of the motor. When the power is higher than the load the motor will continue to turn and the clutch will slip and makes a clicking sound. This prevents damage to he load or the motor.

KA in the past had problems with gears breaking. Perhaps they have incorporated a torque control design in the gears.

Mine is over 40 years old and the only clicking I get is when I pour in frozen blueberries and the paddle has to go over them! Nancy

Thanks all.

Anyone else out there with the Proline 7qt mixer that has had some experience?

Dcarch - sounds like finding the dial this involves taking off the top. I'm still within my Christmas return window of Jan 31st, so probably better to exchange than attempt this. But this may help others, so thank you for sharing.

You misunderstood dcarch. He was suggesting that it was Possible that some kind of slip clutch was designed into your model. This would not be adjustable and there would be no reason to look inside the housing. You certainly could call KA and ask if such a thing is installed.

However, as I mentioned above, even if such a thing was designed into newer units, it should not happen with a light load such as you showed. Therefore, I think it unlikely that such a clutch is part of your design. I think I would return the unit.

I get the click on a 6 qt model when it's being overworked. Mine is a few years old but it feels like what dcarch is describing--a gear thing. But we're talking big loads of whole wheat dough for mine to be overworked, and yours should be breezing through what you're clicking on.

This not comparing apples to apples etc....Don't have a model exact like yours, this is my story.....

.I have a 2 yr old Kitchen Aid Pro 5qt Plus, with a bowel lift. it works great on heavy loads such as my bread making which I do on a regular bases. The machine itself is heavy , is an effort for me to move up to cabinet top, I store it underneath usually, as I don't likes lots setting on my cabinet counter tops.

DH decided I needed something smaller and lighter. He orders a Kitchen Aid 5qt Artisan tilt head mixer. Yes it is lighter and smaller..... BUT....it is fine on light loads, on the mixing of my breads the head wants to jump up and down some (you can put pressure on top of motor and it stops the up and down jumps) and it does have a click. A first I thought Oh Great I got a lemon.......DH is not concerned, his thinking is the the heavy loads puts stress on motors and gears. "Don't worry about it" he says.

Time will tell....

I decided to return it. Have unpacked the new one and given the parts a good wash. Significantly more grease on the planetary part and the base that gets lifted up and down on the new one that needed to be wiped down. Also performed the dime test and set the bowl at the right height. Plan to give it a good test on Thursday when we will be hit by the next snow storm. I will report back on how the new machine performs.

I think that was the best thing to do. That's way too much money to spend on a mixer to not be able to even mix a cookie batch without making strange noises! That is supposed to be a powerful mixer.

Well I returned it and the new one clicks on a single recipe of Hawaiian rolls. Frustrating. KA says it is normal. Certainly doesn't sound normal and makes for a loud baking session. Hawaiian Roll Recipe
