We are on the third night of a six night trip to the California coast. When getting ready to do the dishes my wife announces "no hot water". This happened before about two months ago at which time with help from JD I was able to get everything working. It stayed working for a five night trip to the central coast. This time I first checked the CB and the 2amp fuse on the circuit board. Both appeared fine. Next I unplugged the connector on the circuit board no joy, next I unplugged reconnected the red ECO wire the gas lit for just a moment. Next I turned the AC off and the DSI light came on and stayed on. I then turned everything off waited about 2 min. turned both back on and the gas was lit when I checked. I think I have an intermittent circuit board. I will call JD tomorrow to see what to do next. We almost made it with no issues. Our next trip is for three weeks and about 2000 miles, I need everything to work.
