Mixer has a broken gear or tooth in the head.
Hi. You have experienced the problem that many hundreds of kitchenaid mixer owners have. No doubt your mixer began having problems while you were mixing bread or cookie dough. Kitchenaid advertises that these mixers can handle these types of dough, the brutal truth is they cannot, for one very important reason. The cheap plastic transmission housing has failed, and as a result has caused damage to your mixer's transmission.
This cheap plastic part supports two of the most important shafts and gears in your mixer and has no business being installed in a high priced mixer. Heavy doughs place enormous stresses on these gears and shafts and this plastic part is not up to the task, Kitchenaid knows this of course, but refuses to issue a recall notice.
If your mixer is still covered by warranty, call Kitchenaid's so-called customer satisfaction dept. and demand a mixer replacement with a METAL transmission housing.
If out of warranty, unplug the mixer and don't use it. Remove the silver band from around the head of the mixer, then remove the four screws that secure the cover, remove it. At the front top of the mixer locate the transmission cover, if it's made of a shiny metal, you're in luck. If it's made of plastic, examine it carefully for cracks around the mounting screws or anywhere else on the housing. If you find cracks, you have found the culprit that has caused untold internal damage to yoúr mixer
If you are up to the task of repairing it, go to the kitchenaid.com website and do a search for your model's parts catalog. Download it, it will help with the disassembly and reassembly of the mixer.
You'll need to remove virtually all of the old grease. Remove the trans. components and wipe them clean, in order to correctly assess damage. When you determine which parts need replacement, you must insist on a metal housing when ordering parts. Try mendingshed.com for parts. You can also order parts from Kitchenaid...Just be prepared to wait at least a month for them to arrive from Kitchenaid! "For the Way It's Made"?
Finally regrease with Chevron FM ALC EP-2 a Food Grade lube.
Be sure to tell the people at Kitchenaid what you think of their cheap plastic housing!
