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 Service Manual for your mixer can be found at:

http://www.kitchenaidparts.eu/documents/pdf/service-manual/classic-svc-manual-new-email-version.pdf

Among the causes for the mixer not turning on are (in no particular order) --

The leaf-spring switch on the Control Plate is not making contact.
The Phase Board is defective.
Brushes need replacement.
Brush chamfered side not correctly oriented.
Bad armature or field coil.
Seized motor bearing.
Detached or broken Control Board spring.
Speed Control Link plastic end broken.

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.

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.

More likely the pedestal base is bent. Your local service agent has probably seen it before and should be able to bend it back flat again. It's a brutal process with a heavy soft hammer that you probably won't want to see.

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.

The head bounce sounds as if the locking hook is not engaged properly when you slide the head-lock lever to the locked position.

If this is the case, you will need to disassemble the mixer to make sure the link from the lever to hook is not bent. Another possibility is that the slot in the base the hook engages. If this is broken away, the hook will not be able to hold the head in place (I sure hope that this is not the problem).

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.

Hello Heather,

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

If the mixer is working on the other speeds, it needs adjustment to the speed control plate. See the Service Manual:

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.
