Water Heater

Ok, another newbie question. Having trouble with hot water heater. Propane is working cause the stovetop is fine. 2018 Thor Four Winds 22b. When we have turned the switch inside the coach (just the other day), it’s clicked and I heard the heater come on. Now there’s no click. Looking at the heater outside, we assume the pilot is not on, but don’t know how to start it manually or even check for it. Of course, nothing in any of the owners manuals tells us anything.... anybody got an idea?

Would really help US help YOU if you posted BRAND/MODEL of water heater......on label in outside compartment


Don't see many models with pilot flames anymore..most use DSI (direct spark ignition) to light the main flame
So you need to have 12V DC to water heater for it to operate on propane.
(Some also need the 12V DC to operate the 120V AC electric element)


Brand/Model cause there are differences in how they function & circuit used

”Dometic 6 gallon water heater” is the only ‘name’ listed. (I don’t know how to add a picture- trying). Directions say, “turn lighting control to off position”. Don’t know WHERE or what that is! Usually you can see the flame (in a metal circle) when it’s heating.

Picture is sideways - sorry. The flame is usually in the round section on the bottom right, behind the pipe.

OK'


That is an Atwood gas /electric 6 gallon water heater that uses 12V DC to operate the electric AND propane systems (Electric 120V AC is triggered via DC Relay)

GC6A-10E should be model number.




A common 12V DC source goes to both electric & gas On/Off Switches
From the switches 12V DC goes to circuit bd....White wire/electric & Orange wire/propane
Then 12V DC goes to/from the T-stat via Brown (bottom brown wire to 'thermal fuse in clear tubing to t-stat then back to top brown wire)


SO first place to verify you have 12V DC is at connector on White wire (electric) and Orange wire (propane) with Switch ON
No DC then check for blown FUSE in DC Dist Panel



Got DC on white or orange wire then verify you have DC to t-stat on brown wire
Thermal fuse (in clear tubing blows if exposed to 190*F temp due to flare-back out of combustion chamber).....you can remove it from brown wire/off t-stat and connect brown wire from connector onto T-stat to test operation.
Thermal Fuse has to be replaced if it blows.


Here is the FULL Wiring Diagram.......

Well, thank you Old-Biscuit. I appreciate you detail. We will have to stop somewhere to have this checked out. Not equipped with the knowledge to even check. I appreciate your time in laying this out, though!

When you try it on propane.....does the RED Fault Light come ON?


IF YES....then you have DC to water heater \
2 things will cause RED Fault light when trying to use propane
1) Flame fails to light off and PROVE it lit.
2) ECO (Energy Cut Off----High temp t-stat) OPENED


To Reset and try again turn On/Off Switch OFF---wait 30seconds then turn back ON


Might help in diagnosing issues with not working.


If you are connected to AC Shore Power...try using the Electric Element to heat with

Is the water temp cool enough to be calling for the heat?

Old-Bisquit -
By the ‘red fault light’ do you mean the light inside the coach by the switch (pilot light off if lit)? If so then, no, it does not come on. Checked the fuses inside the coach - are there others?? All seems fine inside the fuse box.

Definitely cool enough. We’ve had low 40’s at night, this week.

Oh - and every time we’ve tried to use the electric for hot water heater, we have blown fuses.

Blown fuses.......no RED Fault Light
No propane/no electric heating


Not familiar enough to use voltmeter...
SO time to call a Mobile RV Tech to troubleshoot what is shorting out (blown fuses)
If at a CG......ask Staff who to call.

Did you turn the control panel switch for the water heater to on position?
