Kitcchen Aid mixer making a grinding noise

Hi - I have the Kitchen Aid Ultra Power 300 stand mixer.  While making batter for banana bread this morning it started making an awful grinding sound.  The mixer still turned, but the noise is unbearable and the unit started to get very hot. I've had it for 12 years now and use it only once or twice a month, cleaning it and putting it away after each use.  Any thoughts?


Thank you!

How to use food grinder attachment

The mixer's planetary is not disconnected when the meat grinder is attached and continues to turn.

If the noise you hear only occurs when the grinder is in place, then the grinder may be assumed to be the cause. Consult the meat grinder's instructions and make sure that nothing is loose or overtightened.

Makes a grinding noise at higher speeds

If it is leaking you are going to have to go inside the gearbox to change the grease so whatever is wrong inside may become obvious when you take it apart. Remove accessory cap from the front and look for any dryish grindings inside there.

Grinding noise when running.

It very likely sounds like a plastic gear that is worn. If this is the case, then a replacement is very likely stocked by the manufacturer only.

I advise opening the unit to identify which one you need, then 'phone the manufacturer with the make model and year of the product.

If they say they do not stock it - then I'm afraid that's as far as you can go with this.

Is 300 w mixer powerful enough to mix bread dough?

Your mixer is easily able to handle the kneading of bread dough. Please advise:

9 cups of all purpose white flour, maximum.

6 cups of specialty flour, maximum. This is any flour besides all purpose white.

Bread doughs are only to be needed on speed 2, and never for longer than 7 minutes.

This is all stated in the Use and Care guide for the mixer itself. If these guidelines are not followed, it may lead to a product failure.

Grinding Noise

If it's metallic sound you are loosing teeth on a gear or two.  This is caused by lack of lubricant or simply fatigue of the material of the gears.  Don't use it, you can get metal flakes in your food.

Take it in to a repair shop and have it fixed.  The money spent is well worth it because if done correctly will last another 12 years.
