Joann B Bloomingdale , OH August 23, 2015 Appliance: KitchenAid 6 Quart Professional 600 Bowl Lift Stand Mixer KP26M1XPM5 Kitchenaid Mixer Kp26m1xpm5: The planetary was bent from the plastic screw nut working loose and falling into the mixer bowl while running. How to replace All Purpose Appliance Cleaner. My husband took it apart and we ordered a new planetary, he just put it back together and it works like new. I just want to say that we were unsure of the part to order so we called in to appliance Parts Pro and talked to a man who was the absolute most help we could ever ask for! He did the order and everything was perfect and I am delighted to have my mixer again. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
