Messed up while putting the brush spring back into the side of the mixer and left the power on. While inserting the brush head there was a pop and spark. Now when I insert the brush head (double checked the orientation) the motor still won’t turn on. Guess that means I shorted something, but is there anything I can do to fix it from here?

Just looked up owners manual. This has a dimmer style speed control, since it’s a dc equivalent motor design (brushes are clue). Dollar to a doughnut you burnt the triac (power controlling “transistor”). Disassemble to remove board, a fairly large 3 lead part will have a “crater” in the middle. Replace the board (or the triac if familiar enough) and ‘mem not to play with power attached.

I just did the same thing, i.e., had a "spark flash" on 2 different KitchenAid stand mixers when replacing a brush (stupid of me to have it plugged in and power on while performing this operation) and thereafter neither would run again. There is a small circuit board on the rear end of the mixer, in my case Whirlpool P/N WPW10325124 BOARD-PHAS. I purchased 2 new phaser boards, installed them and both mixers worked perfectly thereafter. The link below provides instructions on how to replace the circuit board.
