HI, brand new camper with a Dometic water heater model # WH-6GEA gas and electric. Dealer is 400 miles away and I'm not leaving it for 6 months lol. Heater worked for 3 days and then quit. I have power from both switches and T-stat going into control board but there is nothing at the 2 amp fuse on the board. I used a jumper from one of the hot wires directly to the fuse and it fired right up. Bought a 2nd board and have the same issues, possibly another bad board? Thanks in advance for help.

Which hot wire did you jumper to the fuse and then it worked? That means the wire or where it is from is no good, not the fuse or the board. Whyinheck would you buy a new board for that? Or else I misunderstand ?EDIT--which side of the fuse did you jumper to---maybe it is a blown fuse

No power after that point to the fuse. I dont know much about these and assumed it was the board.

I only have an old WH but it does have the board with a 2 amp fuse. I think you are saying you by-passed the big plug with the pos wires that goes into the circuit board, and went to the fuse and then it all worked.It can happen that plug, if it slides onto the edge of the board, loses good contact. Cure is to pull it off, clean off the contact part on the board and anything in the plug contacts and put it back on. Wiggle it some, see if that gets you contact again.

My expertise only runs to wiggling it or hitting it with a bigger hammer!One of our actual techs should be along to save the day soon :)
