Question about KitchenAid KSM90 Ultra Power Series Stand Mixer
I use it weekly. Usually kneading around 4 cups of flour.
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 giving the bowl an extra twist when mounting it, you may need a new screw cap (the piece the bowl locks into). This is a part easily obtained.

Hi. Stop using your mixer. If your mixer is still covered by warranty, call Kitchenaid Customer Service, they are very good with warranty repairs.
If your mixer is out of warranty, remove the silver band that surrounds the top of mixer. Remove the top cover. At the front of the mixer, locate the transmission housing which is now exposed. Examine this housing carefully for cracks. If you find cracks anywhere in this housing, you have found the under-engineered plastic transmission housing. Kitchenaid's replacement housing is made of metal. Your plastic housing has no business being in a mixer that is marketed as being able to mix bread dough. It cannot!
If you're confident that you can make the repairs yourself, go to the Kitchenaid website and download the parts drawings. Remove the Trans. housing, remove the worm gear shaft assembly which is driven by the motor.. Remove and save as much grease as necessary to thoroughly inspect the worm gear. Inspect the worm shaft bearings. Look for cracks, or missing pieces on the bearings. Look for crunched cogs on all gears. Be prepared to wait at least a month for your parts to arrive after you order them. The replacement grease should be Shell Darina 2, or Chevron FM ALC EP 2.
If you're not confident about repairing this yourself, call Kitchenaid and determine the nearest "approved" repair shop.
You may be able to pressure Kitchenaid to pay for the damaged parts in your mixer. They are still installing these plastic Trans. housing on new mixers. Insist on a metal cover when replacing. Apparently, Kitchenaid feels no shame in their manufacturing process, and will not issue a recall notice for these housings. They are substandard at best.

Given the age of a 3-C stand mixer, finding additional parts for it will be exceedingly difficult. The best recommendation is through E-Bay or antiques stores - a specialty dealer. Kitchenaid parts distributors will no longer have anything in inventory for the 3-C mixer.

Hi REEDKL, Merry Christmas and Happy New Year! Based on your mixer’s symptoms, my first thought is that your mixer’s internal controller assembly (the speed knob), has gone bad. The inspection and troubleshooting of the control assembly is something you can do yourself, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer.
If you're lacking one, you can download it from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in this case, KP26M1, and then select the last file: KP2671XWH3.pdf (325.07 KB) that appear under Parts List (21). Check to see that it matches your mixer model.
Turn to page 4, Case, Gearing and Planetary Assembly and locate Illus. #8, Control Assembly. This is what you’re looking for when you get the top (Illus. #1) off the mixer head.
First check to see if any of the connections have come loose. If everything looks tight then you probably need to replace it. Unfortunately the whole controller assembly is on a little PC board filled with resistors, capacitors and diodes, which was not meant to be 'home fixed' and where my ‘electronic expertise' ends. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not, or you can just order replacement parts without the testing.
Although you don’t need to get further inside your mixer to make this repair, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer that you might want to keep in your ‘toolbox’, should you have to delve inside your mixer in the future. The mixers displayed in the links may be different than your KA model, but the principles are the same.
If you feel this repair is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Testimonial: "This is great information! I never expected to find help like this. Will move on it. Thanks!"
SOURCE: Motor head locking lever is
The problem that you are experiencing is due to the torque that is put on the head while mixing dough. The lock is still working fine, although it is getting wear. You can replace the locking mechanism. However, it will work for a while longer. If you want to change the mechanism post back to this thread and I will be happy to locate you one and explain how to change it.
