Kitchenaid mixer. Top is loose so it bounces when

Hi MJANKOW520. I?m going to assume your KA mixer is a ?Tilt-Head? mixer. You don?t say specifically. Based on your description of the symptoms you mixer exhibits, I would say that your head locking mechanism (or a component) of it is either broken, worn or loosened due to normal wear and tear and need to be readjusted (or repaired) for it to keep your mixer head stationery. The inspection and troubleshooting of the inside of your mixer is a DITY capability, particularly if your mixer is out of warranty. Just 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: http://www.kitchenaid.com/flash.cmd?/#/page/home. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, try K45SSW, and select the file listed under Parts List (check to see it this matches your mixer model). This parts list manual provides an exploded view for the disassembly and reassembly of your mixer, along with all the part name and numbers. Turn to page3, titled: Base and Pedestal Unit. You?ll want to focus on Illus. #9, Link & Lever Latch assembly, which locks the mixer head to the pedestal when run your mixer. Check to see if something is just loose, exceedingly worn or broken. If something has broken, you can order replacement parts and install yourself. As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping. Once apart you can check for any other unseemly wear and tear on other mixer components. It can be messy but quite gratifying to diagnose and repair your mixer yourself. Finally, here's a link to an excellent site that details the disassembly and replacement of a mixer's grease, which might be helpful, too. http://www.foodonthefood.com/food_on_the_food/2009/04/how-to-repair-a-kitchenaid-mixer-yourself.html If you feel this is beyond your capabilities and would be too difficult to do yourself you can take your mixer to a local small appliance repair shop and have them troubleshoot and fix your mixer. KA Customer Care can provide you with the name and phone # of the closest authorized KA repair shop in your area or you can do a Online web search, but be sure to get at least three estimates before deciding to commit to one repair shop. Good luck. I hope this helps. Howard, Burke, VA If this solution has helped you, please rate it, thanks! - hslincoln

I was having the same problem with the head of my mixer bouncing around, especially when making bread dough. The problem seemed like it was slowly getting progressively worse.
I started taking a closer look at the problem. When I turned the mixer on its side and looked at the hinge (between the head and the stand) from the opening on the bottom of the stand, I noticed a gap between the flat head screw on the hinge and the inside of the stand (when the head is down and locked in place). This is what allows the head to bounce around.
By adjusting the screw with the head tilted back I was able to eliminate the wobble between the head and the stand.
I hope my solution helps some people.
