No apology needed, I wasn't chastising you. The more info you can provide to the members the better able they will be to assist you.
I agree with the water in a harness idea. The same thing happened to our class C after it was power washed-the water heater quit working.
We waited a day and after things dried out the water heater worked fine.
Maybe you will have similar results after a day or so.
As mentioned earlier, I'd look for boxes with connectors and make sure the connections are dry.
I don't do power washing anymore.
Wish I could be more help, but I have a gasser.
I'm sure some diesel folks will be along shortly to assist you.
