Water heater not heating

Is it possible for you to take and post a picture of the hose where it keeps coming off?

I'll try. We have it in storage but hopefully I'll get up there in the next couple days.

The tank is under the vehicle so its design is such that I don't open valves, though there is an emergency cutoff.

You stated in previous posts that you have opened or closed a valve. In one post you state that you don't know which way to turn it to open it.

I'd suggest to take your problem to an RV service garage or call a mobile technician proficient in propane systems. Ask him to show you how the service valve opens and closes. Mark an arrow on the valve so when you forget which direction to turn, it is clearly marked.

I sent a video to the RV people, showing it go clickclickclick. We got a reply today. The tech apologized for not telling us that when he works on something with gas, he turns the gas off before returning it to its parking space. I guess a lot of people leave the thing parked for six months at a time, so why give it a chance to slowly leak? We're atypical, though: 17 trips and 16,000 miles in one year, and we're not retired.

So my guess that it was possible that it was off because they'd forgotten to turn it back on was kind of a right answer for the wrong reason.

He also said that it was possible that air had gotten into the line and said if we ran the gas awhile through the burners, we could get it running again. He had brought it into the shop and done all that and said the water heater now works, as does the refrigerator and the heat.

He said if I can get up there before they close one night he will walk me through the whole thing. So we'll get it all cleared up soon enough.

Thanks again to all who posted!
