Kitchenaid 550 hd seems to bump during mixing

Buy a new one quick. Or hide. Spent . electrical engineering. And supply of new diodes resistors and capacitors are needed.

It is more than likely in the planetary or the fuse gear inside the gear box. Try it once you have the planetary off before you go looking inside the gear box. Easiest is planetary problem but far far more likely is the fuse gear.

Check different outlet. Make sure the outlet isn't at fault.

You can adjust the mixer bowl up and down slightly. If you lower your bowl and look at the back you will see a little screw, it looks like a flat head screw and it is on the "neck" of the mixer.
You can raise and lower the bowl by adjusting this cam screw. You can tell that your bowl is adjust correctly by attaching the flat beater and put a dime in the bottom of the bowl, the beater should just barely touch the dime and move it around the bottom of the bowl.

The beater will not scrape the sides of the bowl, if you are wanting the sides of the bowl scraped I would recommend the Flex Edge Beater made by KitchenAid which is basically a flat beater with a rubberized edge which will scrape the side of the bowl as it rotates.

Here is a link to the flex edge beater on our website: http://www.mendingshed.com/kfe6l.html
Let me know if you have any other questions.
Thank you,

Hi Susan. There is no worse feeling than the feeling you get when you find that you've been seperated from your hard-earned money by a company that markets a product with glowing phrases of what their product can do...And then doesn't deliver on it's promises. Kitchenaid mixers can make short work of bread dough NOT! My Kitchenaid HD Pro (475 watts) self destructed after only 30 uses of making my Sourdough Bread. The problem? A cheap piece of plastic that takes the stresses of two important shafts in the mixer. Cheap, shoddy parts in a mixer you paid top dollar for. Kitchenaid shows no shame in doing so.

What is happening with your mixer as it tries to mix your dough is that the head unit is thrust back and forth and side to side (bucking). Eventually hinges become loose and sloppy. Kitchenaid's behaviour is legal and beyond reproach, so make your next mixer purchase an informed one.

Goto www.consumeraffairs.com and do a search for your Kitchenaid model. You'll notice that you're not alone in your mixer troubles.

I solved my mixer problems by buying a used Hobart 20qt. Commercial mixer (A200) and rebuilt it. When mixing heavy dough you should only use about 60% of the bowl capacity. less, if your mixer is agonizing with the amount of food in the bowl..

You will be able to replace the thumb screw. Be prepared to wait for at least a month for the part to arrive once ordered.

If this solution has assisted you, please rate it. Good luck! ricardok45

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.
