Hot water issue!
2017 Cedar creek 36CKTS. I Am camping in SC and it is our first outing in this camper. Problem: Tankless hot water heater will not produce hot water. Here is our story so far: LP tank full and working as indicated by cooktop works fine. Water flows freely to all faucets including outside shower. Minimal hot briefly at first then gone. Will not revive itself. No hot exhaust from outside. I have checked fuse. Have cycled hot water off on as indicated in instruction booklet. Tried Fw switch to no avail. Any thoughts?

Yes. And it's shut.
But oddly...it doesn't matter what positions the valves are in......I have water. Just not hot.

This thread might help. It's got some interesting insight into tankless water heaters.

I've talked through it with someone who has identical unit. His works, mine doesnt.
I'm out of ideas. If it can be tried, I've tried it.

On our 2017 36CKTS I found that it takes 7 -8 seconds of running water to even start to get warm. I also found that a couple of times I had hot water and then it turned cold. I looked at the fault light in the switch panel and found it on so I switched the hot water off then back on. It work after that. I also opened the back panel of the water heater and changed the DIP switches to have 130 F water. So far working okay. It still takes 7-8 seconds of running water to get even close to warm. The tankless works off of water flow so it you take a "camping" shower by getting wet then shutting water off to lather up. It will take another 7-8 seconds to get warm water. This is just what I have found with mine. Might make sure that the propane is actually getting to the water heater. Just another thought are the water lines hooked up correctly with hot on the left.

"Fault light on switch panel"?
Duuno what that is.
I wonder if I'm even doing any of this right.
I can't get it warm at all any more....period.
I just have "tank on" switch. I know, no tank....but that is the switch. The other switch is pump on....for fresh water tank.
Clearly a "cockpit error", but this is driving me insane.

I can't even guess about your unit but many units have a Tank Heater switch to operate the 12v tank heater pads on waste and FW tanks. Mine doesn't have a label but it does turn red when the cold weather tank heater switch is on.

It's hard for me to see in your pic... but I think the heater 'fault light' is the little red dot (light) between the water heater switch and the water pump switch. [Doesn't it say FLT underneath it?]

Yes. But that is for FW water tank only...(it says "pump"...which i don't need on)..I'm on city water. Only switch "on" is tank on switch. That's the only way I know to turn on tank less system. There are no other switches than the ones shown in 2nd pic.

What brand of hot water heater. If its Atwood go outside and take cover off and at the top left corner there is a little bitty reset button. Push it in. Its small so it wont seem like much of a push. Had to do that several times on mine till it finally quit. There was a recall part on mine that I hope fixed the the problem so far so good. This is on a tankless heater. Good luck.

I believe the switch that you have on and is illuminated red is the "arctic pack" heater pads to keep your gray and black tanks warm enough so they do not freeze.
The switch immediately left is your water pump and the switch left of the water pump switch is your water heater switch. Notice the label "water" above those switches spans across both switches.
Unless it is freezing turn off the right switch. Then turn on the left switch. Since you are on a water tap leave the center pump switch off.

For those of us trying to help, you might take a pic straight on to those right side switches without some much of the pic taken up with that big white switch on the left. I can barely read the words on the right switches but IFFFFFFFFF
the word WATER is centered above the two left switches and
the word HEATER is below the first... that means the first switch is for WATER HEATER.
If the word PUMP is under the second switch... that means the second switch is for the WATER PUMP.
You wrote in post #7, '"Fault light on switch panel"?
Duuno what that is.' My post 12 told you it's the little red light between the two above mentioned switches. It's hard for me to see in you pic... but doesn't it have DSI above the red light and FLT below? That means Direct Spark Ignition (you don't have to light a pilot light on this water heater) Fault. If your water heater attempts to light and does not, this FLT (FAULT) light comes on.
I still think the right (red) switch is for your cold weather tank heaters, nothing to do with heating your shower water. These are my best guesses after attempting to decipher your pic.
Oh, yes. You wrote "Tried Fw switch to no avail." I have no idea what a Fw switch is so I can't help with that. Sorry.
