All the more proof I shouldn't work on things

We traded our washer and dryer with some friends of ours who purchased a new one, we took their old one and they took ours to sell. Anyway we got them swapped out and hooked up and running and saw water leaking out of the washer and thought all right whats going on, did we not get something tight. Investigating the situation, Tammy got to put her crime show watching into action, we noticed that it was leaking around where the drain hose is, allright no problem we'll tighten that up, right after we pull the thing off and let the water run everywhere. Shut the machine off quickly and notice hey the plug just got drenched that can't be good. So in my vast electrical knowledge and lack there of, I just go out and turn off all the power to the house to clean this all up with no one getting hurt. Everything clean and dry, drain hose now tightly in position, plug back in go turn back on the power and nothing. Not good maybe it kicked something off, Tammy does more investigating and notices the plug obviously isn't in good so she takes care of it and we are back up and running. I really shouldn't be working on things, trouble is right around the corner.
