HAHAHA !!! I can relate and so can DH !! HE coudn't figure out why the electric chopper wouldn't work when he wanted to chop up the peppers we found at the U-pick it place to make Taco Salsa.. Dear one umm plug it in (he hadn't plugged it in !!LOL) and trust me I have had days like those too !LOL
Very glad you found the "problem" before any major damage was done to your machine !
