KitchenAid Professional 600 Troubleshooting
First Available in November 2006. Model Number: KP26M1XER
While the KitchenAid is running the mixer stops, possibly with a loud grinding noise
Loose or faulty gear causes a seizure that stops operation and may need to be replaced. This could result from a faulty worm gear or bevel gear. If it's the worm gear follow our worm gear replacement guide. If it's the bevel gear follow our bevel gear replacement guide.
Lack of grease causes the gears to grind to a halt. The gear housing needs to be opened, and food-grade grease needs to be applied.
Lubricating grease falls from the gear housing into the mixing bowl, usually while mixing a batch
Note: Grease will not harm food. "The grease is food grade and is approved for incidental contact with food prepared in the mixer, although it may discolor light colored frostings or mashed potatoes."
Grease on the gears has separated due to high heat or lack of use. The housing must be taken apart and the bad grease should be cleaned out and replaced with new grease. Follow our bevel gear replacement guide to see how to access the gears. Once you have access to the gears, you can replace the grease.
