KitchenAid 600, Stand Mixer - Loud grinding noise, happened when mixing bread dough. When bowl is lowered (dough hook disengaged)....no noise, hook turns. When bowl is raised so that hook engages dough, NOISE and hook stops turning. What have I broken ? Any suggestions to fix will be most appreciated.

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.

If the beater is grinding when it meets resistance, it generally indicates that an internal gear has broken or been stripped.

With the Professional 600 stand mixer, up to 14 cups of white flour or only 8 cups of any flour are recommended at one time. Speed 2 is the only speed that should be used for bread dough and it should never be kneaded for longer than 7 minutes. Failure to do any of these things make cause problems for the mixer motor.

If you are interested in self-repair, I recommend mendingshed.com. They have internal parts available to order and also have a .pdf file for the Kitchenaid Mixer Service Manual.

This is a listing of certified repair locations.

Also, if the mixer is less than a year old, Kitchenaid may replace it under their 1 Year Manufacturer's Warranty. I would recommend calling their customer service. Their toll-free telephone number is:

All right, I'm pretty irritated with Kitchenaid to say the least! I have a lightly used 3 year old Kitchenaid 600 professional stand mixer (model KP26M1XPM). The few times I've used it, I've loved it. I went to turn it on to make cookie dough today and the speed is broken. When the lever is placed in the "stir" position, nothing happens. Then, when moved into the "2" position, it goes bananas fast. In fact, fast and super fast are the only speeds it knows.

I'm not generally a fix-it yourself person, but if there's something easy I can do to avoid the 85.00 fix it fee from the "approved" shop the kitchen aid customer service person referred me to, I'd like to take care of the issue myself.

Help!

Thanks,

Megan E.
