When you open it, there is are contact points and a piece that has to touch to change the speed. It may just be slightly bent or out of place. Some food may have gotten in there.

SOURCE: mixer speed turned erratic!
I would recommend that you first check the Hall effect sensor which determines the speed. I had this exact problem and I actually went out and bought another Hall sensor for about $13. I replaced the original sensor and made sure that the connection between the sensor and control board was nice and snug. My blender worked as good as new! But I was curious to know if my original sensor was defective so I put it back in mixer and again made sure all of the connections were tight. Guess what? My original sensor also made my mixer work! There was nothing wrong with my original Hall effect sensor except the connection between the control board and sensor was not adequate--unfortunately I didn't check the connections before I decided to buy another one. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations.
1. Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall effect sensor looks like. BTW the part number is 9703312. 2. You'll need a phillips head screwdriver to open up the mixer. 3. Make sure that the connection between the control board and sensor is absolutely tight and snug. 4. Also, make sure that the orientation of the sensor connection between the control board and sensor is correct. it's hard to know which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or facing down. If, after you've made the connections, the mixer still doesn't work. Disconnect the sensor and reconnect it with the prongs facing the opposite direction and try it. I actually found the right orientation through trial and error. By going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work it were reconnected with correct orientation. 5. This whole process probably takes less than 10-15 minutes to perform. 6. Make sure you use common sense and unplug the mixer when making connections and such.

I suspect you (speed) Control Plate Assembly has gone bad and needs to be
The good news is that this can be fixed quite easily (OK, maybe with a little effort) by yourself if you are a DITY type person, feel adventurous, and your mixer is not under warranty. However, before you start to disassemble your mixer, be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use K45SSW, and select the file listed under Parts List (1), K45SSWH0.pdf (341.41 KB). Check to ensure it matches your mixer model.
Turn to pages 6 & 7, titled: Motor And Control Parts, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the parts. Find Illus. No. 25, Control Plate Assembly, Part No. 240904-2, which is the part that needs to be replaced.
As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping.
Here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Motor brushes are fairly cheap to buy. It sounds like the first place to start: http://kitchenaidmixerspares.co.uk/Home/tabid/36/ProductID/88/Default.aspx

the triac solid-state component on the board for the motor speed control is shorted and you need a new control board, unless you can find an outsource replacement triac,most companies won't sell you parts because of liability issues on internal parts of the unit
