KitchenAid wobbles when mixing

Does the KitchenAid Ultrapower mixer (model KMS90) require maintenance?  
We unpacked ours after moving and there was some oil on the packing paper.  We thought nothing of it till we tried to make cookies and the mixer wobbled as it mixed the dough.   Seems as thought the gears were rough too - but no bad.   The mixer is old but gets light usage.  
Any ideas on how to fix the wobble?  Does the unit need oil?

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.

My kitchenaid mixer speed control is locked in the off position and wont move. It was working 2 min earlier when it was turned off from a prior mix.


You can try moving the lever slightly up or down while moving it forward to see if this will free it it or make a difference. Otherwise, the spring inside may have snapped or the speedlink cam may have came loose or broke. Either one will require the top end assembly to be removed to replace these parts.

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.

I have a KitchenAid Artisan stand mixer (325 watts/model KSM150), about 5 years old. Lately, when mixing dough for bread or cookies, the motor head of the machine wobbles a bit from side to side. In...


the solution to this is to tighten the screw visible through the base that intersects the pin. Turn the machine upside down and using a long flat screwdriver tighten the screw.

Hello, my Kitchenaid stand mixer KSM90 Ultrapower will not turn on. Have just replaced the phase control board and new brushes, still have the same problem


Check that the brushes are the right way round. They will go in the hole in four positions, but only one is right. Use a torch to check inside the hole. Also check the fuse.

I can only imagine you have a shop display machine and they took the plug off. Otherwise it should be obvious.

KitchenAid wobbles when mixing


Do not store or transport the mixer on its side ever. Always upright. The grease in the gearbox should even out eventually. Try sitting on it when it wobbles. At least yours works.

Kitchenaid Classic -Mixer Head wobbles or shakes back and forth


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.

If the beater to bowl adjustment quickly comes out of alignment, you may need to seek service. You may find a Kitchenaid certified service location locally at the following website:

Yes, First unplug the unit.On either sides of the mixer there are two black motor brush retainer screws. Carefully remove them paying attention to the motor brush keyed position.You will see that one side is keyed.Check to see if the brush is competely worn down,or possibly cracked ( replace ).Always reinstall brushes the same way they came out.This should solve the problem.
