Oasis Hydronic water heating

[purplekeenah]

Woke up this morning to find we had no hot water. Everything was fine last night after our showers and dish washing. While trying to find the cause I had the Newmar supplied sketches of the fuses, breakers, etc., there are supposedly (2) fuses for the Hydronic system on a board that is described as being in the basement compartment that has the shore power hookup. Much to my dismay, I can not locate that board. The only things inside that compartment is the power line reel, cable hookup, automatic transfer switch, and a whole lot of other terminal-type wiring. Any ideas?

Racklefratz, you got it. The problem is the AQUA STAT, sensor that is clipped to the hot water delivery line.

Most likely the summer loop pump has failed. On the Oasis panel, are there any fault lights illuminated ? On top of the panel, there is a bypass switch, turn it on and see if your hot water returns.

No idea which system your coach has installed. But in our Tiffin, and when the same issue occurred, it turned out to be a failed thermostatic sensor which, if failed, disables the system, resulting in no hot water. Ours is HydroHot.
