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.

When attempting to start the device it will not start

Faulty outlet plug does not provide power to motor. Follow our power cord replacement guide to see how to replace it.

Wires leading to switch are unplugged, loose, or damaged. Open the device and check for damaged wires. Follow our speed selector switch replacement guide to see how the wires are suppose to look.

The mixer will only run at certain speeds and will either not work or work poorly at a specific speed setting.

Wires leading to switch are unplugged, loose, or damaged and may need to be plugged in or replaced.

Speed-Selector is broken and in need of replacement. Follow our speed selctor replacement guide for quick and easy instructions on how to do so.

The beater will not go into the spindle or gets stuck in the spindle and is hard to get out

My model is 6000 pro. It has everything fine, grease, gears and outlet plug. Just stop and restart after several seconds. What could cause that?

Please note: I am not an Authorized or Certified Kitchenaid Mixer Repair Person. I am an Electrical Engineer

If we eliminate the gears/grease/power outlet plug as possible problems, there remains one remaining part (maybe two parts). I’ve personally seen issues with the Speed Control Circuit Board. The Speed Control Circuit Board is the only circuit board under the top cover of the Kitchenaid Stand Mixer 600 Pro Series. There are a few reasons for this board to act up. One common issue, would be this circuit board over time would accumulate gunk in the area where the mixer’s speed selector is located. This gunk is usually residual amounts of whatever has been prepared with the mixer. Another issue with this circuit board may actually be a bad electrical component(s) on the circuit board. Replacing this circuit board may be the best option; Part #: KitchenAid 9706648 Control Assembly. I hope this is helpful.
