How do I Troubleshoot a Kitchenaid KSM90?


The KitchenAid KSM90 is an ultra power series 300 watts stand mixer. KitchenAid is a well-known and dependable brand in kitchen appliances. These mixers usually have more power than other brands and can significantly cut down mixing time. However, as with most appliances that have multiple moving components, wear and tear can occur. Before taking your mixer in for an expensive repair, there are a few basic troubleshooting steps you can run through at home.

Things You'll Need

  • Flathead screwdriver
  • Adjust the flat-beater if it strikes the bottom of the bowl or is too far away from the bowl. With the tilt head model, unplug the stand mixer and lift the motor head. Turn the screw counterclockwise to raise the flat-beater and clockwise to lower it. Adjust the flat-beater so that it clears the bowl. Take care not to over-adjust the screw as the bowl may not be able to lock into place. For the bowl lift model, the steps are the same except with this model you will need to place the bowl lift handle in the down position to access the screw.

  • Check to see that the mixer is securely plugged into the wall unit if it fails to operate. Turn the stand mixer off for 10 to15 seconds then turn it back on. If it still does not start, allow the unit to cool for 30 minutes before switching it back on.

  • Check the home electrical panel for any tripped breakers and broken or burned fuses. Reset any tripped breakers and replace fuses as necessary. The breaker may have to be reset a few times before it clicks into place. Take care not to force it. Replace fuses with others of the same amperage.

  • Make sure the motor head is down and securely in the LOCK position before starting to mix. If you can raise the head then the motor is not secure.

  • Mixing time with the KitchenAid may be a lot shorter than other brands of mixers. Take care to adjust the mix time to avoid over-beating.

Tips & Warnings

  • If the beater or wire whip is adjusted too close to the bottom of the bowl, the coating could wear off the beater and the wires may wear through on the wire whip.
  • The stand mixer may warm up after use under a heavy load and extended mixing times. This is normal. Take care not to burn your hand on the top of the mixer.
  • Do not use an extension cord as this could cause overheating.
  • When mixing cake batters with the KitchenAid, mixing time may be half as long as other brands of mixers.
  • The stand mixer's electrical motor may have a strong smell when first used. This is normal.
  • Do not take the mixer in to the retail store you purchased the unit from as they will not provide service.
  • Always unplug the mixer from the wall socket when not in use and when taking off parts and cleaning.
  • Always remove the flat-beater and dough hook from the unit before cleaning.
  • To contact KitchenAid about your mixer, call 800-541-6390.
  • Always keep hands, hair and utensils away from the beater when in use.
