Does kitchenaide have different bowls for the Pro 600?

I have the same problem. It appears to be due to a design flaw-the planetary assembly is press fitted to the drive shaft, and will come loose, to the point where the entire assembly will drop out of the machine. This could be a serious safety issue if the beater and bowl is not in place when the machine is powered on.

Although I have been able to put the planetary assembly back into place using a good amount of effort, the assembly has fallen off repeatedly. Googling the issue has shown that this is a common issue that is particular to the Pro 600 series of mixers.

Contacting KitchenAid through their website as well as by phone has proven unsuccessful so far. I was offered a 50% discount on a new machine (mine is out of warranty). However, no one at KitchenAid to date has been able to verify that there have been any design changes have been made to address the issue. I am still awaiting a call from the factory to determine if there have been any changes to the design, or if there is a way to repair the machine that is approved by KitchenAid.

I was able to find one person who reported success by using a pin to secure the assembly-see this link http://www.fixya.com/support/t6519821-planetary_assembly_fell_off

While this may address your issue, be advised that this may void the warranty on your mixer.

Good luck!

Kitchenaid does not make a 4 or 5 quart bowl that would fit your 6 quart mixer, but other 3rd party companies do!
You may be in luck.
I haven't seen this bowl in person, but it apparently will fit your 6qt mixer. Here is a link to a page selling the mentioned attachment. It comes in a set, with appropriate wire-whip attachments:

All of the new style that are made after 2002 0r 3 that are bowl lift models and up untill 2008, They no longer make the plastic as it could not handle the work load all are made now with a cast aluminium cover. Hope that helps

First congrats on the great mixer that you have. next the pro 6 or professional 600 series mixers are of an entirely different design than the one that you have even though they are both bowl lift. Do you really need 6 quarts capacity? The pro series is a 575 watt mixer BTW, and it will have more power available to you IF you are doing bread or a lot of food grinding, if that is a requirement that you have then the 6 / 600 series is the better suited mixer but if all you are doing is general medium to light mixing duties then fix and keep the K5SS it a great machine,

look at item 18 on this diagram:

also check to see if any of the other parts are broken. bent or missing.

I found item 18 online for 7 bucks:

nice machine!! enjoy using it. I assume you have no problems with it since no problems are described!!

Several things:

The Professional 600 has a metal gear housing with a metal gearing. Because of this, the Professional 600 will generally run louder than other stand mixers that may have a nylon/metal mesh gearing.

How long is the bread dough being mixed for? Kitchenaid stand mixers must be used on speed 2 for bread doughs, using the spiral shaped dough hook, and mixing for no longer than 7 minutes.

If the flat beater is getting caught on the bottom of the bowl, pleasure assure the bowl is being seated correctly. You will place the bowl on the mixer arms on the left and right hand side. You will also want to take your fingers along the back of the bowl, where it butts up against the base of the mixer, and press downward. You will hear an audible click as the bowl falls into a spring latch and allows the bowl to sit flush and secure. If this is not being done, the flat beater may strike the bottom of the bowl.

If this was not the cause of the problem, please consult your Use and Care Guide about the beater to bowl adjustment. This is an easy adjustment made with a flat head screwdriver that can quickly correct the problem of a flat beater hitting the bottom of the bowl.

mendingshed.com sells a lot of internals for those machines

There is an adjustment screw and a system for setting it. You can find a video of it here (or just a ton of people who know all about these mixers). I just found it while trying to troubleshoot the same problem for my wifes mixer.
