Hi GOTWEIMS. Yes there is only one way to reinstall your brushes and that is so they both seat correctly on the armature's commutator or you won’t get any ‘juice’ to the motor. See the illustration below:
kitchenaid stand mixer ksm90wswh how to install - 815b35c.jpg

If you've turned a brush 90 degrees too much, it won’t seat properly and you’ll get no power to the motor.
It would also be helpful to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> then enter the visitor type “Consumer” and the 6 character model number, in your case use KSM90P, in the Model Number box. Select one the files listed for your model that appears under Parts List (16): KSM90PSWH0.pdf (354.08 KB) and save that file to your PC (check to see it this matches your mixer model).
Turn to pages 6 & 7, titled “Motor And Control Parts”, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. Locate Illus No 32, Brush holder that includes #18, 20, 21, 22, 23, and 31 which is the brush holder and brush & Spring assembly respectively. This illustration along with my initial reply regarding the orientation of the brushes should allow you to reinstall your brushes with confidence. Good luck, I hope this helps. Howard, Burke, VA

I believe the brushes and the spring are one piece, so the brush should come out with the spring. Either the brushes are so worn that you just aren't noticing the little bit that's left, or the block has come loose from the spring. You can tip the machine over so the brush hole is facing down and let gravity do the work. If there's any brush left inside, it should slide out. Otherwise just install the new brushes.

I took the side screw out now it won't turn on.


The brushes aren't contacting the commutator on the motor. Remove both screws, insert a small phillips screwdriver into the exposed springs and simply push down until you feel resistance. That should fix it.
Good luck!

I took off the back cap of a 300 mixer. then pulled out the motor brushes. put it back together and now it wont run. What am i missing?


Hi, KIMAMABELL, While working on your mixer be sure to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KSM90P, and select one of the files listed under Parts List (check to see it this matches your mixer model).
Turn to pages 6 & 7, titled “Motor And Control Parts”, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. Locate Illus No 32, Brush holder that includes #18, 20, 21, 22, 23, and 31 which is the brush holder and brush & Spring assembly respectively.
The brushes need to be installed so that they both seat correctly on the armature's commutator and it’s possible when you reinstalled them, one or both brushes were turned incorrectly.
The illustration below shows the correct orientation of the brushes and should allow you to reinstall them with confidence.

Here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer for your future referennce.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer.
Good luck! I hope this helps. Howard, Burke, VA

Took out/put back black brushs/motor wont turn on


Hi TUBEARS, from what you’re describing, I suspect that one or both of the brushes is (are) not seated properly when you reinstalled them. The brushes need to be installed so that they both seat correctly on the armature's commutator or you won’t get any ‘juice’ to the motor. See the illustration below:
ff450a7.jpg
I'd suggest removing them again and making sure the concave contact face rests completely on the armature’s commutator. If you've turned it 90 degrees too much, it won’t seat properly and you get no power to the motor.
It would also be helpful to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use K45SSW, and select the first file K45SSWH0.pdf (341.41 KB) listed under Parts List (1) and then check to verify this matches your mixer model.
Turn to pages 6 & 7, titled “Motor And Control Parts”, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. Locate Illus No 32, Brush holder assembly that includes Illus. Nos. #18, 21, 22, 23 & 31, and Illus. No. 19, Brush & Spring assembly respectively.
The Parts List illustration along with the picture above regarding the orientation of the brushes should get your mixer powered back up and operational. Good luck! I hope this helps. Howard, Burke, VA

Hi REDEN828, yes, you are correct. When you reinstalled them you either misaligned one or both brushes so they are not seated properly on the motor's armature. See the illustration below:

My Kitchenaid mixer is tripping the power in my house. I removed the back and found two identical springs loose in the machine. Have you seen this problem before? Cheers Anthony.


Anthony,

Based on your description, it sounds like those identical springs are a part of your motor brushes. Normally, they would be attached to the motor brushes (depending on model), which are located behind the 2 slotted round access caps about mid way, front-back on the cover assy. My hunch is that the spring(s) may have gotten dislodged during a previous dis-reassembly and had came in contact with the armature and a grounded component causing a short and circuit overload ( breaker trip). I suggest that you locate the appropriate diagram for your mixer and ensure that your brushes are assembled correctly - all parts accounted for. You can get diagrams and parts lists from various online vendors, such as: http://www.appliancepartspros.com/partsearch/modelsearch.aspx?model=k45ss Use the 'Motor and Control' diagram as a reference.

Good luck!

KitchenAid Mixer stopped working after I took the black screws on the side out. Thought that I put it back in right with the springs. Maybe I didn't. What could have happened? Thanks Nancy


The brushes must be insert in a particular manner in order for it to work correctly. If you remove the brushes and shine a flashlight into the hole, you should see a small detent or "stop" in one corner of the hole. Its a square hole. Match this corner with the corner of the brush which is shaved off. The brush is not square; it has one corner shaved or smoothed down. This allows the brush to fully extend into the hole. If the brush is inserted any other way, it will not contact the motor and will not run.
