Propane/240 Electric water heater help needed 2022 Nexus Ghost

[MoHoRemy]

I have a 2022 Nexus Ghost I moved into full time yesterday. I cannot get my hot water heater to function on either propane (gas on on tank, switch to propane mode on panel above the sink) or in electric mode (switch on above sink). On the water heater panel on the outside I have it set to "on" comfort. I also tried "eco" on.
I'm the third owner. I'm not sure if it's ever worked. When I bought it and drove it out to WA state, the dealer I bought it from told me it didn't work and they paid a local RV shop to replace the element. That didn't work. They also found the feed line was totally kinked under the sink.
I've called Nexus several times and haven't receive any calls back.
I have a Mobile Repair guy look at it yesterday and he was stumped.
Any suggestions?

Have you gone through any trouble shooting. If you don't have a manual it should be herehttps://www.truma.com/service/download-center/

Third owner of a 5-year-old rig. That did not raise a warning flag? Are you sure that the unit is getting proper battery voltage? Needed for both AC and Propane operation. If power good and both not working one of the safeties have tripped and it is disabled. Do you have the manual? Link above. Try to locate a Truma service center or a person the really knows these units. They are just a bit complicated.
