No Hot Water From Truma Instant HW Heater

    We just bought a new 2018 Fleetwood Discovery LXE 40G and we are first time RVers so I am sure it is a rookie error. Set up last night on our first trip and can't get hot water from the Truma HW. I turned the HW system on in all 3 locations but I do not get an LED light on the dial in the closet. The FireFly system shows propane full and then apparently loses connectivity to the propane monitor as it shows an x in the propane position. 

    Any suggestions?

    I finally got mine to work by: Propane valve open, on Firefly Water Heater On, in Truma recess outside the RV On, switch in bathroom cabinet to On.  If you have the light on, I'd check the propane valve.  Maybe the Water Heater bypass in the water utility compartment?
