So model of the Atwood still needed. (what is motor aid?)

My previous Winnebago Class C had a functioning "motor aid" water heater. Just like a radiator hose runs to your vehicle heater to heat the vehicle in cold weather, a radiator hose runs to a pipe running through your water heater. It heats the water in your water heater while you drive so that when you park, you already have hot water.

I see heater hoses running into the back of the water heater so apparently I have the same model. How hot does it get the water?

Roughly 130*F after 2 hours drive time
The 'heat exchanger'/'motor-aid' is just a 1/2" tube on exterior of tank wall ---hot engine coolant flows from engine thru tube back to engine

Not as hot as propane, but uncomfortably hot to the touch.

Light on On/Off Switch is a FAULT Light---should come on when:
*Propane Flame Fails to light/fails to prove it lit
*ECO has tripped (failure of normal temp T-stat)

Reset Fault Light...turn switch Off then back ON

It seems odd to me that Atwood would change how that on/off switch works with the red light. Must be confusing where it does one thing with some models and another thing with other models.

I have the Direct Ignition GH6-6E except with a newer control board and flame sensor set-up. The OEM red light works the same though. It comes on as soon as you turn the switch to "on" and it goes out when the heater starts (when you hear it come on) After that, if there is trouble and it does not stay lit the red light comes back on. (now acting as the fault light)

However the manual's schematic calls it the "Non-Ignition Light", but then says in the instructions for starting after you turn the switch to "on", "If the switch light stays on longer than 15 seconds, place the switch in "off" and wait 5 minutes" and try again.

The red light and switch worked the same way with the Suburban WH we had in the 2003 5er, except ISTR there was something about 3 tries, I forget details of that 3 tries thing.

1991 and a 6E are 19-20 yr versions

Little changes were made with each new version.
Then in 2004 they went to a DC Control for Electric/Gas Version
(10E/6 gal and a 4E/10 gal)

Now for 2020 they have a NEW 6gal/9gal XT Model that has the Electric Element access in outside compartment.

Time marches on...new versions...new control schemes

It is a good idea to put some electrical de-oxidation grease on the four wire connector. I use it on most of the electrical connections that are subject to moisture.

Will do. Thanks for the tip.

Got it! I was used to the old rocker switch-light that lit when turned on and went off when the thermostat turn off the gas. Water got hot so I'm good! Thanks!
