Question about KitchenAid 32685 Mixer

Knocking sound, pin loose

While running, my KitchenAid classic makes a knocking sound. It seemed to be loose at the pin that joins the motor housing to the stand. The last time I used the mixer, the pin actually came half out of its hole. The mixer was brand new and has only been in use for a couple of months (6-8 uses total).

    I've never used a stand mixer before, so I wasn't sure whether they are supposed to run smoothly, or if maybe the knocking was normal.... I guess the pin having come out answers that question?!?

    Hi. Great solution. It worked perfectly. I had the same problem with my artisan stand mixer. While on the top would clank and the pin would gradually "walk out" of place. So, turn the mixer over. The screw is a slotted screw inside the base of the mixer. You can only see it by turning it over. At first I thought they meant the screw you see when you lift the top up. It is not. You have to turn it over and look inside the base. You'll see it there deep inside where the top and bottom join. By the way, I called and described this to KitchenAid and they said it could only be fixed by an authorized service person. Ha!!! They are 40 miles away and I use my mixer every day to bake bread. Guess if I ever want a second career, I'm qualified to be an authorized repair person now. Thank you so much!!!!

    My pin had come out completely and it was near impossible to put back in. I separated the top from the bottom at the hinge, squirted some olive oil in the hinge hole, put it back together and used a hammer to hammer the pin back through and it slid right in. I then tightened that small screw you were referring to, and it is good as new. Thanks so much!

I came across this site looking for the same answer. I tinkered with my KSM90 model and think I found the solution.


If the hinge pin is vibrating out of its slot, unplug the mixer and flip it upside down. (Removing the bowl makes it easier). You should see a screw centered over the hinge pin. Center the hinge pin and tighten the screw.


This should do it, although I tightened about every other screw on the machine before I found this one.


Let us know if it works

    Wow! I am so impressed with the internet. I was in the middle of whipping eggwhites for a white chocolate buttercream frosting for a cake I'm making for a big celebration when the pin in my Kitchenaid KMS 90came out....and I could not get it to go back in. I held the top to the bottom by manually!!! until I finished the frosting. I was afraid the machine was kaput since I've had it for about ten years... then checked on line and found this wonderful site...I turned it over, found the screw, loosened it, was able to get the pin back in and then tightened it. YAY!!! Thank you very much!!

My pin came right out and I couldn't get it back in. I turned it upside down like someone recommended and loosened the screw, still couldn't get it to line up and go all the way through. I finally put a little cooking oil on the pin, turned the machine on it's side, and it went all the way through. Then I retightened the screw.

I have the same problem, but still can't get the pin to go all the way through. I tried oiling it as suggested above, but had no luck - it sill won't go any further than the hinge - I have tried from both sides. Until I get this sorted out, my expensive Kitchenaid mixer cannot be used.

Hahaha!!!! Yes, tightening the screw from the underside made the whole thing run as good as new!!! I thought that it was that the pin was worn out and that I would need to get a new one, so I took that as an opportunity to convince my wife that a Bosch mixer is better (since that's what I grew up using and my mom still has it 30+ years later.) So now we have a new Bosch and a runs like new KitchenAid!!!! Asi es la vida!!! :)

Yikes! General rule of thumb is, with electronics, if you hear something rattling or coming loose that shouldnt be get it worked on or looked at immediately before it causes more damage. Since yours is still under the manufacturers warranty immediately contact them to see what the steps are under the warranty. My sister had the same issue which was beyond the warranty it was only the matter of months before it died on here. this is something that cant be fixed by yourself I'm sorry to say...

Why wont my classic kitchenaid mixer switch off

Good Morning,

There is a spring inside your mixer attached to the speed control switch and speed control arm, the spring can sometimes get caught on the slide bar that is just below it inside the mixer. The other reason is that the speed control switch plate in the rear of the machine (that the spring attaches to) vibrates the three speed adjustment screws out or in and the spring will pull the speed switch (control arm that you use to control mixing speed when using the mixer) back to the stir position after you try to turn the mixer off.

If it is a spring problem you will have to do a full tear down to get at the spring and either free it or replace it. If it is a problem with the adjustment screws on the speed plate, that can be handled at the rear of the machine and is twice as easy to get at but sometimes much more frustrating to adjust. There are "YouTube" videos on the internet that will walk you through the process of adjusting your speed control plate just Google "adjusting speed on kitchenaid mixer" I hope this helps. please let us know if it does and if you have other questions just post them here and we will "FixYa"

How to I install a cotter pin that came out?

Are you are referring to the pivot pin that joins the mixer head to the stand?

If so, it can be slid in place after you turn the whole mixer on its side and look up the underside of the stand. There is a screw which locks the pin in place. Loosen the screw and the pin will go into place. Tighten the screw afterwards.

How to replace motor in kitchenaid artisan mixer

Sounds like a worm gear problem to me, it's impossible for the motor (armature) to move far enough to not drive the gear. There are driving pins in the system from fuse gear to paddle.
1) in the fuse gear
2) inside gearbox above planetary joining shaft to bevel gear
3) through planetary and shaft

There is also one joining the little gear inside the planetary to the shaft, doubt you'd break that one though.

Mixer motor quit.

I think that the motor is still fine. Get a Copy of the Repair Part List from
First thing I would do is to check the two Motor Brushes (one on each
side of the Motor Housing). Make sure they are not worn out, and when
inserted, they must both make contact with the Motor Coils. If even
one of them is not in contact with the coils, the motor will not run.
You can also remove the Motor Housing and visually verify that they
are touching the Coils.

My wife's kitchenaid classic 250 watt mixer wobbles on the base

It sounds like your mixer likes to take a beating, ive never dropped one and for good reason, they weigh quite a bit. first check to see if all the rubber legs on the bottom are still there. if they are the only possible solution to fix it after being bent or warped is to either re-shape the part using a tool strong enough to do the job, or to replace the parts needed. the hinge pin part number is 16910. is the base is bent the part number is 240151-1. If the lower portion of the mixer itself is bent or warped this is a serious problem and will require you to dissassemble the entire unit. part number for the lower gearcase is 240350-4 Please not that all the parts list are white in colour. hope this helps.

Whisk is stuck..can't be removed. what can i do? mixer is kitchen aid c 4. thanks for any suggestions!!

We had this same issue with our KitchenAid Mixer. Whether it is the whisk attachment or the paddle, the problem is that stuff (most likely sugar based) got into the attachment connection area and dried. It seems like a little sugar couldn't possibly glue the attachments to the stand mixer, but it does.

The solution is to turn the mixer on it's side and pour a kettle or two of boiling water on the section that joins the mixer to the attachments. Pour slowly to allow boiling water to penetrate grooves. Wiggle a little, pour more water, repeat... that should allow you to get it off.

In the future make sure to soak the attachments in boiling water every once and a while to allow all the gook to loose. And let it fully dry before reattaching to mixer.

KitchenAid wobbles when mixing

The "wobbling" sounds like an issue of beater to bowl adjustment, which can come out of alignment naturally over time and with use of the machine.

If the flat beater is striking the bottom of your bowl, this may cause the locking mechanism to loosen and may cause the mixing head to "bounce" during use.

Your Use and Care Guide will cover the "beater to bowl adjustment," which you can do at home in a few minutes with a flathead screwdriver.

Also, leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.
