My Kitchenaid Pro 600 stand mixer stopped working. The planetary gear just stopped turning.


My KitchenAid pro 600 stand mixer stopped working. It just wouldn’t turn. It’s less than 4 years old. I contacted KitchenAid and they said my options were to buy a new one or pay to have it fixed. What?! The life expectancy of a $500 appliance needs to be more than 4 years. They replied that they have a low failure rate. I thought that they should have no difficulty repairing or replacing the odd lemon if it’s that uncommon. Nope.

Well, I use it all the time for kneading bread, making pasta, grinding meat for sausage, spiralizing vegetables (to be pretty and add interest to a salad. I’m not falling for the fake pasta business), etc. etc. I had too much invested in all the accessories to walk away from it. So, I went online to see how to fix it. I found an excellent repair video that put up. (Those blue letters are a link to the video). The guy is wonderfully thorough. That thing that wont turn is called a planetary gear.

I posted about it on Facebook and it turns out that a number of my friends had had the exact same problem. Since the failure rate is clearly a little higher than what they suggest  😉 (maybe they’re averaging in the longevity of the old mixers that used to work for 30 years in their numbers), I thought I’d post about the fix so you wont get super frustrated if it happens to yours.

I pulled my mixer over to the kitchen table next to my laptop and started taking it apart with the video.

There’s tons of grease involved, and there’s metal shavings from the damaged gears in those, so it’s best to toss on some surgical gloves. Or your fingers will feel a little sore and itchy for a long time. <ask me how I know> He instructs you to replace any of the damaged gears. I examined each one as I was going along, and they all looked fine, so I was worried I wouldn’t be able to recognize a damaged gear.

Then I saw it! The teeth on the worm follower gear looked completely stripped. Haha! I needed a new worm follower gear, and new planetary grease. (You have to replace the planetary grease regardless of what else you’re replacing so that the metal in the old grease wont wear down your shiny new gears!) IMG_5952I went on e replacement parts, and they were out of stock on the worm follower gear. Bummer, because I really wanted to support the business that made the video. I found the parts on Amazon. The total was $60. I could have saved $30 if I’d gone with another brand’s grease, but it had mixed reviews, so I decided not to mess with that.

IMG_5958I popped them in today, and bam! Working mixer. Just like that! 🙂 Thank goodness, because this girl’s in the mood for a little pasta!IMG_6399

These are the replacement parts I got, but it depends on which gear(s) of yours are damaged.

    1. Thanks Mimi! Yeah, I was surprised. I had a Breville problem once. They asked for pics, and diagnosed the problem over the phone. They said, “Sorry. That shouldn’t happen.” They sent out a replacement and told me to toss the broken one. I was floored, and bought their big espresso maker soon after that.
      Awesome! Which two did you make? Do you love it already? Their show is really great, too.


  1. I frequently turn to YouTube for solutions. My countertop ice maker quit working, and a video helped me by pointing out the cause of the failure. Fortunately, I was able to make the repair without taking the whole thing apart as shown in the video.

  2. I’m a 64 yo woman and my gear went out also. I ordered the part, and checked YouTube for a video tutorial. After having to buy a couple tool, i fix3d it myself and back to baking bread! Its quite simple to do. Messy but very proud of myself!
