Suburban IW60 On Demand Hot Water Heater

Update. I replaced the air pressure switch, don’t think that was the problem. I also replaced the temperature demand probe. Not sure about that. I did find one of the 5 amp fuses (there are 2 of them on the board) that was blown. I put two new ones in. Before I did all that I unplugged from shore and disconnected the battery. So I now have a constant flame but little to no hot water. There is a constant blue flame but the coils are like warm at best but could probably not quite warm either. Waiting on the two stage regulator and the electrode flam probe. A tech said there should be a green light in the board. Anyone have an idea where that is on the mother board.

Ok so for some reason I had hot water in the shower and had to Temper it with cold to my likings. My wife showered this morning. She too had hot water. She did have to turn it on and off a few times and then it provided hot steady water theoughout her shower. So I guess I’ll see what happens over the next few days. Maybe I’ve fixed it????

Any update on this, I am having the same issue, it runs for a bit then goes cold.

Update,
We never got it to be really hot to the point of needing to add cold water to temper the temp down. Now, we just got back from an out of country trip, tried to showered and back to square one. No hot water, ignitor goes on and off, lights 3 times and then quites.

So, still questioning a fuel pressure regulator issue or a water pressure issue. Thoughts????

Ok, well now when trying to fire, I hear the ignitor, it attempts 3 times and quits, I have an E1 Code on the temp screen in the camper. Also, I noticed that the blowers rpm's go up and down. Then when it quites, the blowers go to a high speed until I guess the "cool down" cycle is completes and shuts off. I just need to figure out if it's a fuel regularor issue ( smell propane while it's trying to ignite and it does briefly ignites and goes out), a water pressure issue ( really don't hink it's that. Help if you can.
