Vibrates and is louder than it use to be whenever I use it.

Remove the bowl, turn it upside down on a towel, look up inside the pedestal. Right in the middle where the hinge pin goes through there is a screw, unscrew it a little, push the hinge pin back to where it belongs and then tighten the screw up tight. Turn mixer up the right way, raise head up, fit bowl & flat paddle. Lower head & turn machine on low, listen for paddle tinging on bowl, if it is touching turn off and raise the head. Look into hinge area from the front, that screw is the head height adjustment. Clockwise to lower paddle in bowl, anti clockwise to raise. You want to lower it until you hear the paddle tinging on the bowl & then raise it enough to clear without tinging. You don't wind the screw in & out huge amounts, 1/4 to 1/2 a turn at a time is plenty.

Hiya,

It sounds like you need to adjust the head height on your mixer.
I have added a link below for our help page on adjusting your mixers head height.

I hope this helps you :)

Are you engaging the head lock during operation? if not that is why it is loose. If you are it is not uncommon for the head to move around a little under heavy loads, when I make bread the head is always trying to come up so I have to use the head lock switch whenever I use the mixer on bread. It is the only time I lock it down.

Two. One easy one not so much. There are three screws underneath the motor on your mixer. any one of these screws coming loos will cause the moter compartment to vibrate and move about, easy fix remove motor and retightem. Really is an easy fix 15 mins. second solution; one of the motor mount screw positions have broken and the motor head is no longer fully attached to your support tower and it will have to be replace which means a full tear down and a new part ordered and installed. look at the bottom of the motor head where the power cord goes into the mixer and look for cracks in the metal. Let us know what you find. We can direct you to the proper sites for parts list and parts.

A screw has come loose and is jammed. You need to take bottom cover off and loosen bolts in neck (2). This will seperate neck from motor head and you will find loose screw jammed in tilt section.

See pg. 13 of the owners manual for bowl height adjustment procedure:

clockwise to lower the head and counterclockwise to raise the head for more clearance for the beaters.

I assume you mean that the top half of the mixer, above the pivot pin, moves with respect to the lower half of the mixer, the stand part. There is a pin on which the top half pivots which becomes loose.

Turn the mixer over and look up where the pin goes through the two pieces. There is a screw there which secures the pin. Tap the pin into position and tighten the screw.

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

The height of the beater is easy to adjust on the tilt-head model.  Tilt the head back, and look into the pivot from the front of the mixer.  You should see a screw on the hinge.  With a flat blade screwdriver, rotate this screw half a turn counter-clockwise to raise the beater height.  Lower the head and check that the beater does not touch the bowl.  Repeat until the adjustment is satisfactory.  To lower the beater closer to the bowl, turn the screw clockwise instead.

I just fixed mine this moring!!
Solution:
1- Lift head. In the lifted position you will see the head of an adjusting screw. Turn it to the left say a half turn.
2- Lower head and see if it is still too low. If so, do it again.

I had to turn mine like two plus full turns.
I beleive it goes into a nylon insert so that the threads are cut as the screw is put in the first time. If the screw is too loose, it may be possible that over time the head could slowly drop because of vibration and the screw slowly moving inward again. If that happens, a new nylon insert may be needed (but that is a different story).

There is another screw that may be loose of the head moves too much right and left. I also had that issue. This screw will be seen if you lay the machine on its side and look up the shaft (pedestal) of the base (large empty area the head attaches to). You will see a small screw head (first item up the open part). That set screw holds the unit in position on the hinge pin to stop movement from right and left.

Hope this helps.
