Mixer leaking oil
I called KitchenAid about this issue with my mixer. The agent on the phone told me they are aware that it tends to happen to some mixers after they sit for some time. Basically, a "lifetime" of grease has been packed into the assembly and it is normal for it to release grease on occasion. I was told to run the mixer at 10 for at least 2 minutes to get it going and I should see a reduction in the oil leak. I had about a tablespoon worth of oil dripping down off the assembly. I was told that if over time it seemed to amount to about 1/4 cup then I should call to see about repairs due to a potentially bad seal. I was also told that the repair for that would most likely NOT cost the same as a new appliance.

The KitchenAid KSM 90 WW
You will find that the fuse gear has failed, it's either been overloaded or it's just worn out from use or maybe the lubricating grease has gone old and needs changing. That will be change the failed gear and replace the grease.

Oil leaking. Called KitchenAid,
Kitchen Aid is 100% correct. The cause of the problem is age and lack of regular use, the oils in the gearbox grease separate from the solids over time and the oil then leaks out at the planetary and sometimes where the 2 case halves join under the silver trim band.
If you are up for a small job knock the chrome trim ring around the planetary off and clean it out and wipe around the area it covers. It is called a drip ring for good reason, you may find it full of oil.
The grease Kitchen Aid used in their mixers is Food Grade and it's harmless.

High speed stir setting
There are several things that regulate the speed, we will assume that the adjustment has not been messed about with. If the governor on the motor armature that presses against the underside of the square black speed control plate at the back has not flown apart then I would replace the small pcb (phase board) on the top under the back cover. One screw and 4 wires hold it on.

Mixer won't turn on
Just recheck that you really have put the brushes back in the right way, use a torch and look in the hole. The brushes can each go in 4 ways, only one of which will work. Look for the blocker and line it up with the cut off corner on the brush. It's normally at the back, one side at the top the other at the bottom. After that you need to be looking at everything you have done for a booboo. I doubt it will be water ingress. Make sure the switch contacts come together when the lever moves to position 1.

My KitchenAid bowl keeps coming loose when kneading dough. Any solutions?
Either the grooves on the bowl lock plate are worn out, or the grooves on the actual bowl are worn out. I would start with replacing the bowl lock plate. Here is a link to the part: KitchenAid Mixer Bowl Lock Plate 4163032
This part is really easy to replace, it is held into place with three screws, remove those screws (make sure to hang onto those you will need them to re-install the new part). then you should be able to pop the old plate out. To install the new plate like up the screw holes, and press into place, sometimes you need to lightly tap it into place with a rubber mallet as it is suppose to be a very tight fit.
Once that has been replaced your bowl should lock into place tightly. However there is always a chance that the bowl has been worn down and may need to be replaced. Here is a link to the 4.5 Quart bowl: KitchenAid 4 5 Quart Stainless Steel Bowl

Slow speed doesn't work
If the mixer is working on the other speeds, it needs adjustment to the speed control plate. See the Service Manual:

Was working few years but doesn't start at all.It being a month without using it, then trying to turn it on but nothing.No issues before. Watched DIY videos just replaced its Phase board, nothing
You really need to get a Multi meter and follow the power, you have replaced the phase board so we can probably discount it being that.
First check that the switch contacts behind the black control board are really touching when you move the speed control lever to turn the mixer on.
Next the cable, do you have continuity from the wall plug to the control board on phase & neutral, (Check green earth wire as well for the sake of safety) that will be the black wire and the white wire on the 2 lower plug in contacts on the black control board at the back.
Next remove the carbon brushes, do they have reasonable length and most importantly are they fitted correctly with the corner key aligned with the blocker at the bottom of the brush holder.
Next with brushes out check for field winding continuity. On the other side of that black control board to where the power comes in there will be a red wire and a white wire that disappear into the motor housing. One of the wires will have a circuit to one of the brass brush holders and the other wire will have a circuit to the other brush holder. The resistance of both of those circuits should be pretty much identical.
After you have done those tests you should begin to have a clue as to where the problem lies.

My Kitchenaid K5SS 300 watt standing mixer launches into the highest speed regardless of the speed ....
I had a similar problem where the mixer would also go to fast speed right away. On the back at the top was a screw that was loose. After tightening this screw I had 4 speeds but no stir speed. I unscrewed that screw and a bolt fell out. This bolt went to threads on the inside of the area covered by that back plate. I put that bolt back on and tightened it and the corresponding one on the other side and wala the mixer works perfectly at all speeds. Hope it helps. Make sure mixer is unplugged before attempting anything like this (wires are exposed when the back plate is removed - some kind of flexible circuit board).

Runs but doesn't turn. Worm gear is not broken.
Something must be broken if the motor is turning and the planetary is not. It will be one of the following, we will start from the first point of contact with the armature
1) Worm gear broken (fuse gear) you say no teeth broken
2) Worm gear not broken but whole unbroken plastic part not gripping aluminium boss
3) Pin through worm gear broken or missing
4) Pin through centre (or bevel) gear broken or missing
5) Pin through small gear in planetary broken or missing
6) Pin through planetary hub centre shaft broken or missing
The most common ones in order of likelihood are, 1, 2, 3 and 6

The speed switch on our KitchenAid KSM90 won't shut off
Hi NORMR123, it sounds like
your Switch Lever has loosened up and you just need to get to the attaching
screw to tighten everything up. (I trust
you reinstalled the motor brushes correctly so your mixer will run. Many folks attempt repairs by removing the
brushes thinking it will provide access to the inside, then reinstall them
incorrectly and wonder why their mixer doesn’t work.)
sure you 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 if this matches your mixer model).
Although not providing step by step instructions,
the Parts List manual provides an exploded view of the various component
assemblies allowing you to see how the mixer all fits together. It is helpful for the disassembly,
troubleshooting, and reassembly of your mixer.
to pages 6 & 7, titled “Motor And Control Parts”, and locate Ill. Nos. 1,
2, 3, & 4. #1 is your Pivot Screw,
which may have loosened over time. #3 is
your Switch Lever and stud. Check the detent is present or rubbed down. If that’s the case, you may want to replace
far as parts go, here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). Prices can vary
widely between vendors, so do some comparison shopping.
here are some links to several excellent websites that detail the
disassembling/reassembly of a KA Mixer.
these three websites and their excellent pictures and descriptions and your
Parts List manual, you should now be able to completely disassemble, inspect/adjust/replace
your Switch Lever, and reassemble your mixer. Good luck, I hope this helps.

Need manual and part number for brushes on a Kitchenaid RRK90
Well first thing; here is the link to the KitchenAid site where your parts list can be found.
Next, the parts list will tell you what the part number is for the brushes and all the parts that make up the brush assembly. If you need to replace any part other than the brushes you will need to do a full tear down to do that. Also; remember that there are four different ways to replace the brushes but only one way will work. You need to be very careful to remember which way the old brushes come out, there is a beveled edge on one side of the brushes and the new brushes need to go back the exact same way or they will not reach the commutator on the armature and the mixer will not work until the brushes make that contact with the armature.
Lastly the reason that your mixer gets out of time is that over time, 8-10 years of use, the nuts on the speed control switch that hold the three timing screws in place simply get loose due to vibration and the screws can rotate in or out. Some times the screws vibrate loose and the mixer just will not turn on next time the mixer is used. Peeps then think it's broke and will not work so they sell it for parts and by a new mixer. When the only thing they need to fix it is a Phillips screwdriver , a small 3/8th open box wrench and about 20 minutes time to fix it.
Anyway I hope that this helped to answer your question. Please let us know if it helped and if not let me know and I'll try to help fixya.
