Question about Bosch Food Mixers
The Bosch I use is old (number 0710012101 on the bottom) and has been working like a champ until about a month ago. It has started to make a high pitched noise after the first minute or two of use and sounds strained. I thought this was due to the fact that when I make bread dough often makes its way in the bowl shaft and winds its way around the shaft (I take the bowl apart every time I use it to clean out the dough). However, I made cookies yesterday and no dough made its way into the bowl shaft but the high pitched noise once again started after a few minutes of use. The speed of the machine does not appear to be affected, there's just a horrible noise. I don't want to use the machine again until I figure out what could potentially be wrong...any ideas/suggestions?

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.

Hi. Stop using your mixer. If your mixer is still covered by warranty, call Kitchenaid Customer Service, they are very good with warranty repairs.
If your mixer is out of warranty, remove the silver band that surrounds the top of mixer. Remove the top cover. At the front of the mixer, locate the transmission housing which is now exposed. Examine this housing carefully for cracks. If you find cracks anywhere in this housing, you have found the under-engineered plastic transmission housing. Kitchenaid's replacement housing is made of metal. Your plastic housing has no business being in a mixer that is marketed as being able to mix bread dough. It cannot!
If you're confident that you can make the repairs yourself, go to the Kitchenaid website and download the parts drawings. Remove the Trans. housing, remove the worm gear shaft assembly which is driven by the motor.. Remove and save as much grease as necessary to thoroughly inspect the worm gear. Inspect the worm shaft bearings. Look for cracks, or missing pieces on the bearings. Look for crunched cogs on all gears. Be prepared to wait at least a month for your parts to arrive after you order them. The replacement grease should be Shell Darina 2, or Chevron FM ALC EP 2.
If you're not confident about repairing this yourself, call Kitchenaid and determine the nearest "approved" repair shop.
You may be able to pressure Kitchenaid to pay for the damaged parts in your mixer. They are still installing these plastic Trans. housing on new mixers. Insist on a metal cover when replacing. Apparently, Kitchenaid feels no shame in their manufacturing process, and will not issue a recall notice for these housings. They are substandard at best.
If you found this solution helpful, please rate it. Good luck! ricardok45.

Its worth fixing but having someone who specializes in your product is the key, these machines are wonderful products and engineered great. I would say if your mechanically inclined jump on inside the machine and see whats going on, but if your NOT send unit to us USPS it's not that expensive plus you would only have to pay oneway, we will take care of the shipping from our side,,estimated cost $29.00-$49.00
