Spark while replacing brush and now the mixer won't turn on

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?

Answer this question I have this problem too

Is this a good question?

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.
