You won’t need to enter the water heater area again in this manner.

Sadly, because the technology behind that item is still relatively new, it might be difficult to find accurate information from the usual reliable sources.

Water Heater From Dometic Won’t Turn On
If you take it to your repairman, you can feel humiliated in one of those circumstances.
Verify if the water heater is receiving electricity.
This might be as easy as a fuse blowing, a breaker switching off, or your batteries being dead.
There can be an obstruction in the propane gas line if you are using the heater on gas and it won’t ignite.
It won’t operate if there is no gas going to the igniter.
That is, if the heater clicks when you attempt to turn it on.
There is an issue with the spark if you don’t hear the clicking sound and there isn’t any illumination.
A defective circuit board will be another cause.
If there is electricity to the switch but nothing else is occurring, you will discover that issue.
Here, replacement is a possibility.
Water Heater From Dometic Won’t Stay Lit
There are two key factors at play here that contribute to the problem.
The thermostat control valve will be the first component to be examined.
Your heater will not operate correctly if this component is faulty.
This component just needs to be replaced.
The thermocouple is the second component that may be the source.
When functioning properly, this component detects the flame and returns the correct voltage signal to the gas valve.
When something isn’t functioning properly, the thermocouple won’t give that signal, and the gas valve will typically cut off the flow of gas.
The thermocouple will ultimately burn out since it is placed directly on the flame.
Check to see that the flame is clear and properly contacting the thermocouple probe’s end before replacing the component.
Your only option is to have the probe replaced by a certified technician since testing and other adjustments need specialized equipment.
