Beater rubbing bottom of bowl

The beater cannot "heat" the bowl, so I am going to assume that is a typing error, and you meant hitting.
If the beater hits the bowl it is usually caused by the adjusting screw at rear of the column being improperly set. To correct this you need to turn the adjusting screw slightly to right, or left to adjust clearance. Clearance should be 1/16", about the thickness of a dime.
If this does not fix the problem, and the beater still rubs the bottom of the bowl, it can be corrected by tapping the yoke arm with a mallet, there should be 1/16" clearance between bottom of bowl and end of the beater.
You can determine the 1/16" by dropping a dime in the bowl, the flat beater should just "touch" the coin as the beater rotates.
If you have questions feel free to call us @ the Mending Shed.
Thank you,

Put the flat beater on and mount the bowl to the machine. Now look for the screw next to where the beater mounts on the head- this is the adjusting screw. Turn it counterclockwise to lower the beater, just a quarter of a turn, and then check where it's running in the bowl. Repeat as necessary. If you need to raise the beater, just turn the screw the other way.

Although I can't find your mixer by the model number you gave me, I assume that your mixer is the kind which the bowl moves up and down not the "tilt-head" style.

See pg. 12 of the owners manual for bowl height adjustment procedure:

http://shared.whirlpoolcorp.com/assets/pdfs/literature/Use%20and%20Care%20Guide%20-%209707946.pdf

There is a screw in the base of the mixer which is turned
clockwise to raise the bowl
and counterclockwise to lower
the bowl.

It sounds like you have two problems. First, the black marks are usually because of a reaction between the beater and certain chemicals used in dishwashers. Try washing the beater by hand and scrubbing it throughly to remove any residue. If this works, don't use the dishwasher again. You could also buy a plastic coated beater.

It also sounds like the bowl height needs adjusting. There is a screw just under the head for this.

JOE:You don’t say if you have a ‘tilt-head’or a ‘bowl-lift' mixer, but you can easily download a PDF version of your Owners Manual from the KA website (http://www.kitchenaid.com/flash.cmd?/#/page/home).Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number (in your case, use KSM90P)and select the last file listed that appear under Owners Manuals:KSM90PSWW0.pdf (2930.74 KB)and save that file to your PC.You’ll need to have Adobe Reader to be able to open it. Turn to Page 11 and you will find the instructions for adjusting the mixer head height.I have extracted the instructions below:
Beater to Bowl Clearance
Your mixer is adjusted at the factory so that the flat beaterjust clears the bottom of the bowl. If for any reason, the flat beater hits thebottom of the bowl or is too far away from the bowl, clearance

Tilt-Head models
• Unplug mixer.
• Lift motor head.

• Turn screw (A) SLIGHTLY counter clockwise (left) to raise flat beater or clockwise (right) to lower flat beater.
• Make adjustment with flat beater, so it just clears surface of bowl.
If you over adjust the screw, the bowl lock lever may not lock into place.


Bowl-Lift models
• Unplug mixer.
• Place bowl lift handle in down position.

• Turn screw (B) SLIGHTLY counter clockwise (left) to raise flat beater and clockwise (right) to lower flat beater.
•Make adjustments with flat beater, so it just clears surface of bowl.

I hope this helps! –Howard, Burke, VA

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.

Several things:

The Professional 600 has a metal gear housing with a metal gearing. Because of this, the Professional 600 will generally run louder than other stand mixers that may have a nylon/metal mesh gearing.

How long is the bread dough being mixed for? Kitchenaid stand mixers must be used on speed 2 for bread doughs, using the spiral shaped dough hook, and mixing for no longer than 7 minutes.

If the flat beater is getting caught on the bottom of the bowl, pleasure assure the bowl is being seated correctly. You will place the bowl on the mixer arms on the left and right hand side. You will also want to take your fingers along the back of the bowl, where it butts up against the base of the mixer, and press downward. You will hear an audible click as the bowl falls into a spring latch and allows the bowl to sit flush and secure. If this is not being done, the flat beater may strike the bottom of the bowl.

If this was not the cause of the problem, please consult your Use and Care Guide about the beater to bowl adjustment. This is an easy adjustment made with a flat head screwdriver that can quickly correct the problem of a flat beater hitting the bottom of the bowl.

Your beater to bowl clearance has come out of alignment. This can happen naturally over time and with normal use of the appliance. This is something you may correct from home using a flathead screwdriver.

Unplug the mixer, with the bowl and flat beater removed. Tilt the mixing head back as far as the machine will allow. In the exposed hinge, behind where the bowl would normally sit, you will see a 3/8 screw exposed. Turn this screw half a turn counterclockwise (to your left) in order to raise the flat beater from the bottom of the bowl.

This may take a few attempts until the beater is clearing the bottom of the bowl again. If the adjustment screw will no longer turn, do not force it. It is only designed to move so far to make the appropriate adjustment.

Be cautious. Raising the flat beater too high may leave dry ingredients at the bottom of the bowl.

If further information is needed, I would advise you to contact Kitchenaid Customer Service. They may walk through this adjustment through you over the phone and can look into ordering replacement beaters for you also.

Their toll-free telephone number is 1-800-541-6390.

I had an SM100 which did not work when I got it out to make cookies recently. So, I have both bowls available (large and small), beaters, dough hooks, whisks and the use and care book too! I sure will miss that mixer. Contact me at [email protected]

the problem is where the pin on the beater shaft locks into the hook may be wearing down or the hook itself.when you put the hook on see if you get alot of play in the hook (wiggle it and if it feels really loose its worn).its still safe to use but eventually (and this may be quite sometime) the pin may break off the beater shaft.you would then have to replace the pin and hook.
