Had the same problem with dough hook not coming off. Sent to a Viking dealer in Rockford and was quoted $600. to replace gear box. Took it back without repairs and call Viking listed in manual and sent it to them on a Monday and by Friday had it back fixed and no charge.DM

SOURCE: Kitchenaid Mixer head wobbles bad

The solution provided by luannej is useful only if your mixing attachment is striking the surface of the bowl. By adjusting the screw located at the junction of the head and base, you are actually controlling how far the head is allowed to tilt forward and, thus, the height of the attachment above the bottom of the bowl. Although the attachment striking the bottom of the bowl will lead to wobble (and noise!), it isn't usually the root cause of the wobble. In fact, the wobble may be causing the bowl strikes and adjusting the head height only hides the problem.

The head of the mixer is secured to the base by a large steel pin. Any play between the head and base comes from this hinge and its resulting tolerances. To "tighten" the sloppy tolerances causing your wobble, follow these steps: 1) Lock the mixer's head down and turn the entire mixer upside down. 2) Looking deep into the hollow base, find the small slotted set screw. This screw actually presses against the pin and takes up the slop between the head and pin. Note that this screw is not the large slotted screw I mentioned earlier visible when you tilt the head back. 3)Tighten the small set screw as much as you can. Your wobble should be greatly reduced or eliminated now. 4) Lastly, you may want to readjust the large screw controlling the head's tilt to optimize the distance between attachment and bowl. Hope this helps.

The "wobbling" 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.

Also, leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.

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.

SOURCE: The head to my kitchen aid mixer bounces up when kneading dough

Yes! It's the "beater to bowl adjustment" trick. I got the KA shipped to my house yesterday and today is the first time to use it. Well, while making the dough, the locking position keeping switching to the unlocking position plus the bouncing beater head looked very scary.

All I did is follow the guide of the "beater to bowl adjustment'. There is a screw right underneath the middle of the beater head. Turning the screw clock-wise makes the beater head lower so the locking knob can be turned further toward the "Lock" position. I let it keep stirring the dough for long enough like15 minutes and never got unlocked this time.

Thanks, QuiteRoit!
