It seems that the switch is out. The mixer is about 25 years old and I have used it fairly heavily in the past for bread (up tp 5 loaves) and my husband used it for grinding meat. Recently it stopped working when using the blender attachment - our daughter was making smoothies - it started again for one use and now that Christmas is here it stopped entirely. Moving/jiggling the on/off knob got it to go for a second then nothing.
Could it be the switch? How long do these mixers last? Would there be a local repair shop or is this something we could do?
Thanks for your help!

Re: Bosch mixer doesn't run!
It sounds like the switch to me.mixers last awhile as long as there not overloaded.The brushes in the motor also go bad but i think the switch is your problem.Goto home depot/lowes and take the switch with you,dont forget to mark the wires.If they cant help you goto graingers (its a electrical/plumbing wharehouse).let me know,you can use an universal switch if the one you cant find isnt availiable.

I do not know a lot about this machine. I am a DIY fix anything. It sounds like one of the mounting points on either the motor or the gearing gave way. Regardless it is new, send it back & have it fixed or replaced. Sorry, I know that is not what you wanted to hear, but is safest considering your investment.
That could be gears or the motor or the connector to the mixer head etc. Since this is two weeks old I wouldn't even worry about what just take it back and get a replacement. Even the new kitchenaids are very good and very realiable after years of use and abuse. Abuse is something like Dad I tried making sand from some rocks. Still worked after that btw.
You just got a bad unit which from my experience has been pretty rare. It will be under warranty so just get it replaced and enjoy the new one for years to come instead of worrying about this one.
I had (have) the same problem with mine. It would stick occasionally and then one day it wouldn't come off at all. The bowl would unlock and turn like it should but wouldn't lift off. After much time and effort I did manage to get it off and found that the splines on the shaft were scored. When I examined the receiver part, the lugs (splines?) on it were worn allowing the shaft lugs (splines) to overlap the base lugs and thus becoming jammed.
I cleaned everything completely and made a batch of bread dough and it's stuck again.
I think the base receiver needs replaced but it may be part of the transmission and maybe the whole thing needs replaced, I don't know.
I sent an email and left a message with Bosch service and will post again when I hear from them.
I have used the mixer for about 4 years and love it but this problem shouldn't happen I don't think. It seems like a design flaw to me.
Hi BESTATTI2UD.Your KA mixer’s internal gears are factory packed with enough grease to last a lifetime, whatever that means?Depending on the age of your mixer (7 years), where it was stored and how heavily it’s been used; these factors all will eventually cause the grease’s base oil to separate from its additives, with the resultant oil seeping from openings beyond the gasket down the agitator shaft, which is the situation you are experiencing now with your mixer.Gravity can be very insidious.To answer your primary question after 7 years it’s time for some TLC maintenance on you mixer, and yes, you can fix this yourself at home. The inspection and troubleshooting of the inside of your mixer is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the Parts List manual on hand.If you're lacking one, you can download a PDF version from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM150P, and select this file, KSM150PSWH0.pdf (773.44 KB),under Parts List (61) (check to see it matches your mixer model). Turn to pages 4 & 5, titled: Case, Gearing and Planetary Unit, which provides an exploded view for the disassembly and reassembly of your mixer, along with all the parts.You may want to order Part #19, transmission case gasket, and some food-grade grease for starters.Once apart you can check for any other unseemly wear and tear on the gears, etc.It can be messy but very gratifying. When you re-grease your transmission I recommend using a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).As far as parts go, here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com. You should be search for ‘food grade grease’ if you start digging into the transmission. Prices can vary widely between vendors, so do your comparison shopping. Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.The mixers are different models than yours, but the principles are the same.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer, should you decide to go that route. If you feel troubleshooting and repairing is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping. Good luck and have fun. I hope this helps.

Sounds like the motor is going. If it has a lifetime warranty (which I'm surprised to hear) it will be interesting to see if you can get it repaired. There are not many old parts around for the older models. I have one too that just needs the brown knob but can't find one anywhere! Good luck
The mixer motor has probably overheated, as proper use and care was not being followed with the stand mixer.
Bread doughs are recommended to be mixed on speed 2 only and never for longer than 7 minutes. With the resistance of a bread dough that is provided against the beater, mixing for over 7 minutes may overheat mixer and cause smoking.
Please consult your use and care guide to refresh your memory about how to properly use your mixer for making bread doughs.
