Help newbie - hot water stopped working...tried both electric and LP
I have been rv-ing in my new 2014 airstream flying cloud 19 for 3 weeks in Wyoming, and everything working great. I went away for a few days and left my airstream electric on but switched off the electric water heater and the water pressure (city water). I just got back to my airstream and cannot get hot water to work, I turned the city water pressure back on and then switched on the electric water heater switch. When I did this, the red light blinked in the switch, which I thought meant all was working ok, but I get no hot water. After Several attempts, I turned off get electric water heater and tried the LP switch, still no hot water.
Please help a newbie....any ideas appreciated!
