    Unfortunatly this was not an option as the bowl would not lock on to anything as it was in operation. Thanks for the reply anyway. I think it is time for a repair or replacement.

Try lowering the bowl by removing the pad below the base of the bowl.

Just replaced planetary and gears, flat beater still heating bowl. is planetary to be loose or fit tight against mixer head?

The beater cannot "heat" the bowl, so I am going to assume that is a typing error, and you meant hitting.
If the beater hits the bowl it is usually caused by the adjusting screw at rear of the column being improperly set. To correct this you need to turn the adjusting screw slightly to right, or left to adjust clearance. Clearance should be 1/16", about the thickness of a dime.
If this does not fix the problem, and the beater still rubs the bottom of the bowl, it can be corrected by tapping the yoke arm with a mallet, there should be 1/16" clearance between bottom of bowl and end of the beater.
You can determine the 1/16" by dropping a dime in the bowl, the flat beater should just "touch" the coin as the beater rotates.
If you have questions feel free to call us @ the Mending Shed.
Thank you,

The mixing section has a gap in between

Do you mean the beater is not touching the bottom of the bowl? AS in there is a gap between the beater and the bottom of the bowl so it is not mixing all the ingriedients?
If you have a Tilt-head style mixer, you can adjust the beater/bowl clearance by turning out the adjusting screw. Place your bowl on the bowl screw cap, Place the flat beater on the agitator shaft and lower the head of the mixer so the beater is at the bottom of the bowl. There should be a 1/16" clearance between the bowl and the beater, if the beater is too close to the bowl turn in the adjusting screw, and if the beater is too far away turn out the adjusting screw. The adjusting screw can be located by tilting the head of the mixer back, and in the neck of the mixer you will see a flat head adjusting screw.
However if you have a bowl lift mixer and the bowl is too far from the mixer there are a few different way to fix that problem. If the bowl and beater are too far apart start by adjusting the adjustment screw. On this mixer the adjustment screw is under the head. Remove the bowl, and beater and lay the mixer on its back. You should be able to see under the head a screw sticking out, it does not have a head, but a little slot in the screw, use a flat head screw and adjust the beat 1/4 turn. Put the beater and bowl back on and test mixer to see if it the beater has a 1/16" clearance. If it doesn't adjust the screw and 1/4 turn. If after adjusting the screw the beater and bowl still have too much clearance use a mallet and tap both sides of the yoke arm up evenly until 1/16" beater to bowl clearance is met.
You can use the same dime test in the bowl to make sure you have the correct 1/16" measurement for the beater/bowl distance.
Thank you,

Vibrates and beater hits bottom of bowl

Try adjusting the height of the head by turning screw #36 counterclockwise a turn or so. This will raise the mixing head so the beaters no longer hit the bottom of the bowl. Refer to parts list:

If the pivot pin #18 is not centered and secured then center the pin and turn the mixer on its side to tighten screw #31 from underneath the mixer to secure the pivot pin.

Top wobbles and beaters scrape bottom of mixing bowl when in use

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.

Rrk150OB is drooping an dthe pin keeps falling out

I assume you mean the pivot pin on which the top half of the mixer pivots to remove the bowl is sticking out of the side of the stand. Turn the mixer upside down and look up inside the stand which is hollow. You will see a screw. Tap the pin back into position and then tighten the screw.

Now to fix the drooping, and I assume you mean the beaters are hitting the bottom of the bowl, tip the mixer back and look into the hinge area. You will see a rather large screw. Turn it ccw a turn and check the beater to see if it is still hitting the bottom of the bowl. Repeat the procedure until you have 1/4 inch clearance or so from the bottom of the beater to the bowl.

Beater hitting bowl. Very wobbly, won't stand still when

More likely the pedestal base is bent. Your local service agent has probably seen it before and should be able to bend it back flat again. It's a brutal process with a heavy soft hammer that you probably won't want to see.

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!!

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.

Beaters don't reach the bottom of the bowl

There is an adjuster on the model I own - the KSM50... It is a tiny little silver screw at the base of the motor between the screws that mount the bowl mover to the stand. Screwing to the left makes the bowl lower and turning to the right makes the bowl higher. I just adjusted mine. Note - just a slight turn can make a difference, but my screw was SO TIGHT- I had to ask my husband to do it. Plus, it is located in a difficult area for some screwdrivers to fit into. He got mine to budge and now my clearance of beater to bowl ratio is perfect.

:) Hope it works for ya,

KitchenAid Artisan Stand Mixer - Tilt is Tilting too Much & hits the bowl!

This may have a simple solution: This sounds like an issue of beater to bowl adjustment, which can come out of alignment naturally over time and with use of the machine.

If the flat beater is striking the bottom of your bowl, this may cause the locking mechanism to loosen and may cause the mixing head to "bounce" during use.

Your Use and Care Guide will cover the "beater to bowl adjustment," which you can do at home in a few minutes with a flathead screwdriver.
