I used my k45ss mixer last saterday it did the job. I let it plugged until sunday and since then it's dead. What happened... could it be the plug... Sue

Did you clean the are around the variable-speed control lever?

Please be sure to unplug the mixer BEFORE disassembling the mixer.

The K45SS is very similar to the 5-qt. tilt-head Artisan Stand Mixer.
You need to adjust the mixer speeds. Obtain a copy of the K45SS Repair Part List from Kitchenaid.com. Remove the screw holding the End Cover and locate the three screws from the Control Plate. All three (2 top left and right, and 1 bottom) must be adjusted. 1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

good day,

I have heard similar problems when the mixer has been transported. It usually happens if the mixer is transported on its side. If there was any burned flour on the brushes the jostling of the mixer can cuse it to get between the brushes and the armature.

So check the brushes. They get caked up with burned flour. Remove the brush caps and pull the brushes out by their springs, being VERY careful to note the position of them since they only go back in one way. Measure the free length of the spring before pulling it out. It is critical that you write down the length sticking out with very slight pressure on it so that it is seated against the armature when you measure.

Clean the curved surface of the carbon brushes with a sharp knife being careful not to scratch the curved surface. If you have them installed wrong they will not go all the way in and will not contact the armature and it will not run. Measure the length, as done above, of the spring to make sure it is in correctly!! If it is not in correctly the spring will stick out 1/4 inch longer than it should.

I am guessing you mean the bowl is stuck. When this happens tap the handle on the bowl a few times. I usually use the palm of my hand.

This sometimes happens when the two nuts holding the motor in place become loose. To check, open up the back and move the foam around the edge to see the two nuts. Tighten them if they are loose. If the low speed still does not work, the screw adjustment at the bottom of the control plate may need adjustment.
