I have a daughter like that. I usually don't allow her to touch things needing repair unless I want some muscle. I made a mistake and let her look at the electric connection on the 301 I was having trouble with. It took me two days to straighten the tube she bent.
My Universal motor has been to visit my appliance repairman. The external wiring was bare and when I finally got the motor cover off, it was beyond my meager capabilities. The LQS wasn't interested, so off it went to the washer repairman. I know, I could have nearly bought a new motor for what I paid, but it wouldn't have been pretty turquoise.
