I can't adjust the height on my Kitchenaid mixer. I turn the screw but it doesn't change the height of the bowl.

SOURCE: Beater is too low in mixing bowl.

The adjustment screw did work for me but I adjusted using the dough mixer instead of Flat Head mixer as specified (only-realized after reading the manual ;o).

After readjusting using the correct flat head, everything is happy again.

- manual, I don't need a stinking manual !!! ;o)

SOURCE: Kitchenaid Mixer head wobbles bad

The solution provided by luannej is useful only if your mixing attachment is striking the surface of the bowl. By adjusting the screw located at the junction of the head and base, you are actually controlling how far the head is allowed to tilt forward and, thus, the height of the attachment above the bottom of the bowl. Although the attachment striking the bottom of the bowl will lead to wobble (and noise!), it isn't usually the root cause of the wobble. In fact, the wobble may be causing the bowl strikes and adjusting the head height only hides the problem.

The head of the mixer is secured to the base by a large steel pin. Any play between the head and base comes from this hinge and its resulting tolerances. To "tighten" the sloppy tolerances causing your wobble, follow these steps: 1) Lock the mixer's head down and turn the entire mixer upside down. 2) Looking deep into the hollow base, find the small slotted set screw. This screw actually presses against the pin and takes up the slop between the head and pin. Note that this screw is not the large slotted screw I mentioned earlier visible when you tilt the head back. 3)Tighten the small set screw as much as you can. Your wobble should be greatly reduced or eliminated now. 4) Lastly, you may want to readjust the large screw controlling the head's tilt to optimize the distance between attachment and bowl. Hope this helps.

SOURCE: Can't get the screw adjustment to change the height of the bowl

I had a similar problem with mine - the problem turned out to be that I hadn't clicked the bowl into place corectly. If you find the bowl is tilting forward slightly then you probably need to push it into the clip at the back.

SOURCE: beater too low-will not lock

I would check the bottom of the beater blades to see if they are out of shape.,or is the base of the mixer raised somehow to cause this problem

SOURCE: bowl too low

Hi, JAKELEGJEETE, 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 at: (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 KSM5PS)and select the last file listed that appear under Owners Manuals: 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 Beater to Bowl Clearance. I have extracted the instructions below:
Beater to Bowl Clearance
Your mixer is adjusted at the factory so that the flat beater just clears the bottom of the bowl. If for any reason, the flat beater hits the bottom 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.
If you find the adjustment screw missing, you’ll need to replace it. But now you’ll need
I hope this helps! –Howard, Burke, VA
