I have a 2022 Forest River Arctic Wolfe Cherokee. The manual says it has a tankless water heater but I don't think it is. The brand is Dometic.
Water heater has only been used about 14 times. I bought this trailer new but have never used it til now. So I know the water heater wasn't used until two weeks ago.
Now the water is coming out barely lukewarm. Before it was hot on about 30 seconds. Using electric not propane.
What would cause this?
 
If your water heater is electric/propane, then it's probably not a tankless.
Our tankless is propane.
The electric heating element can burn out if it was turned on without water in the water heater. Do you have a model number on that Dometic? Will it work on propane?
 
I've never tried it with propane and it has never been turned on without water. I turn the water heater and the water pump off over night or when I'm gone all day.

I’ve seen a water heater trip its breaker in the breaker panel and I’ve had a failure in the electric on/off switch on the outside face of the heater. I replaced the switch for $5.
 
Your WH is not tankless. It's the basic 6 gallon gas/electric water heater:

This statement is confusing:

"Water heater has only been used about 14 times. I bought this trailer new but have never used it til now."

How can it have used 14 times, yet you haven't used it till now?

As Mr.Dan said, check the electrical panel for blown fuses or tripped circuit breaker.
Are you boondocking? I'm wondering why you're using the water pump but that shouldn't have anything to do with no hot water.
How are you hooked up to 'shore power'?

Assuming it's not tankless, check your bypass valves.

 
yeah , check the bypass valves! They are on the back side of the water heater. There should be 2 valves. But, maybe 3.

I was thinking the same thing.
Having the choice between electric and propane says "that's not tankless"
