Professional 600 - makes loud noise when mixing,often stops as it blends 8 cups of bread flour and "needs a break", flat beater seems to get caught on bottom of bowl - this mixer is 1 yr. old!!

bread is very tuff on mixers. always buy the strongest mixer that you can afford. im guessing the field in the motor fried.

Your guess is correct. Get it cheap on Ebay.

hello step ..... yes. You may have to adjust the height of the bowl a wee bit as it sounds like the dough hook is hitting the side of the bowl..

It tells the steps in your manual.

Easy to do.

If you don't have the manual you can download it for free here http://shared.whirlpoolcorp.com/product_literature/search.jsp?siteCd=KAD

The only part that consistently wears out is the Worm Gear Follower located inside the Transmission housing. The teeth are wearing out and becoming chipped. The clicking noises you hear are made by the Worm Gear banging on the Follower. All the teeth of the Follower are now damaged and the Planetary stops rotating.
Removal and replacing of the Worm Gear Follower is no easy task. Let me know if you need help. (Do not try to remove the Planetary assembly by forcing it with a screwdriver. That is not how it's done.)

Put the flat beater on and mount the bowl to the machine. Now look for the screw next to where the beater mounts on the head- this is the adjusting screw. Turn it counterclockwise to lower the beater, just a quarter of a turn, and then check where it's running in the bowl. Repeat as necessary. If you need to raise the beater, just turn the screw the other way.

Hi - I've been searching for general info on KitchenAid stand mixers and ran across this so I'm throwing my $.02 in... Since KA stand mixer bases are essentially made of cast metal parts, there is a very slim chance that there is a lateral misalignment (side-side) unless it got dropped...eek! Sounds like a head height adjustment issue. Check out this from KitchenAid Conversations:

Good luck.

Your mixer is easily able to handle the kneading of bread dough. Please advise:

9 cups of all purpose white flour, maximum.

6 cups of specialty flour, maximum. This is any flour besides all purpose white.

Bread doughs are only to be needed on speed 2, and never for longer than 7 minutes.

This is all stated in the Use and Care guide for the mixer itself. If these guidelines are not followed, it may lead to a product failure.

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 you found this solution helpful, please rate it. Good luck! ricardok45.

Try a higher speed , this should force the batter out using the centrifugal force generated
