Need help, my N50 made a pop sound and isnt working

EDIT: LoL, problem solved, It short circuited the breaker.... the plug i was plugged in didnt have electricity, N50 works perfectly.

Hello everyone,

Today I used my N50 to make some pizza dough, being a pretty hydrated dough and seeing than 2nd speed worked without hesitating i turned it off, flipped 3rd and flipped the switch back on. Machine worked without hesitating or straining, after about 30 seconds i turned it off, at that moment it made a "pop" sound, as if something shorted out. I wanted to knit the dough a bit more on 2nd speed and when i turned it on nothing happened. I opened the speed selection box to see if something had come loose (in 3rd it was moving but i was holding it), nothing seemed out of order so i checked the back part, where I found that the ground wire had broke from the tab that holds it on the screw. So I re grounded the machine thinking it would work but nothing. The coil looks good, doesnt seem to be burned, also it didnt smell like it got burned. 

I put it back together and let it sit as i ponder and research of what could cause it to not work. I though maybe the switch, but that seems weird.

If you have any idea of what to look at please let me know.

if you have read my other post this is the 1st N50 i bought (here in Switzerland where I am now) the inner coil has been redone about 2 years ago and the grease was also changed.
