On Demand Hot Water Concern

Hello,
We're new to the group, just joined today and excited to be here! We just bought a new 3920fb and hope to begin our full-time adventure in the near future! My question is: On our way home from picking up our new 5th wheel, we spent a couple overnights along the way, and the first night everything was fine, but on night #2 the on demand hot water wouldn't stay on. It would give us hot water for about 20-30 seconds, then shut down. The on-demand display panel threw a code "E2". I haven't contacted the manufacturer yet, but will in the next couple days when we're home & unpacked. Has anyone else experienced this? If so, can you tell me what the issue was?
Thank you
Jeff & Deb

We have just purchased a 3920fb and have been in it a couple of weeks. The hot water did give E2 once. I found it impossible to find out what that meant also. I did the old turn off turn on routine and it has been working great for some time. I feel it was either to low of water flow or the propane missed igniting. At any rate turn off and on works although not nice if you are in shower!!!
We also found it takes some getting used to as far as tap settings. General have hot on full and adjust with cold. Does vary for some reason. Is very nice to have unlimited hot water.

Not sure what model you are referring to. I did not know that On Demand Water Heaters were even an option in 5r. We are seriously looking at a Montana for our first rv purchase. I can possibly give you an idea on the shut down. Most on demand units will call for a minimum flow rate to keep the burner on. Pressur input or restricted flow anywhere. I once had our outdoor shower have the same issue. It turned out the hand shower want had a crimped hose. Fixing that solved the issue.

The on demand heater is a Suburban. I have found out exactly what you stated. You need sufficient flow rate then heater works perfect. They are just starting to put tankless heaters in 5th wheels. This model 3920fb has a bath tub so need lots of hot water. Motor home have had on demand heaters for sometime.

Because of their complexity, compared to a simple gas unit, they have always been something I preferred to not own. I have worked on them for ~40 years. I recently installed an outdoor Noritz NR501 for an outdoor shower. I have truly changed my mind about them. I've taken about 30-40 showers using a single 5 gallon LP grill tank and have yet to exhaust the tank. Very efficient. I'll look for the options in my hunt.
