Question about Water Water Heaters
I found a way to get warm water in the shower, but I'm not sure it qualifies as a solution. After trying everything else I thought that maybe when I was feathering the faucet in the shower toward the cold side so I would get warm water that at a certain point it blocked the flow on the hot water side enough so that the sensor in the hot water heater sensed there was no demand in the line and it shut the water heater off. To test this, I went to the kitchen and turned the kitchen sink faucet all the way to the hot side and then turned it on so that I got a small flow of water. I waited for the water to get hot to be sure the hot water heater was working. Once it was hot, I left it running to keep demand in the line and then I went to the shower and turned the faucet on. When the water got hot I started feathering the control towards the cold side and soon I had warm water. So I think I'm right in that the sensor in the hot water heater was shutting the water heater off when the demand in the shower was lowered to a certain point when I was trying to adjust the water temp in the shower.
So now I can get warm water, but it means I have to leave the hot water running at another fixture in the house to create a false demand in the system so the hot water heater doesn't shut down. Is there a way to adjust the senor in the hot water heater so that it will stay on when I'm using the shower only, so I don't have to waste water by running another faucet when I want to take a shower?

If you look on the outside of the RV, you will find the vent for the water heater behind and access door. There usually is a drain plug and valve located as well. Generally they will be tucked away under the kitchen sink area with internal access as well. You will need to find where the valve that shuts the water off to the unit is and turn it on. Most times the water heater is either electric or propane. But sometimes they are only propane. Once your find the access door, you will know where the water heater is. You can also contact Fleetwood who makes the Pace Arrow to see if they have any information on your unit. Usually your unit info or trim number will be located on a little plaque right by the entrance to the RV. You will need this when you contact them. Hope this helps.

have you checked the error codes on the heater?
you can do this by powering off the controler and pressing the up and down keys for a few seconds. this should take you into the diagnostics mode scroll using the up and down keys till you find the one that has the letter E on it and that will give you the last 8 error codes write them down and get back to me

SOURCE: Water turns cold very quickly
I had the EXACT same problem (installed my tankless last winter and worked fine, now this summer it fluctuates, have to turn the shower completely off and then on again to get any hot water and then it only lasts for a couple of minutes!) Argh - it is frustrating!
Here's what I found: the demand for hot water is lower during the summer (hot) months because the "cold" water coming in is already quite warm. You don't need as much hot water to make the shower temp comfortable. SO, my tankless was shutting off due to low flow demand. I've removed the flow restrictor from my shower head and it helped alot but didn't completely solve the prob. Next step is what has been recommended to me by several people but is much more expensive - change the pressure valve on your shower to a temperature valve. Or just wait til winter and it should work ok again :)
