I have a 2005 fleetwood expedition 38n. I am currently hooked up to 50 amp shore power and am using my water heater in the electric mode and the red fault light is on. The water seems to be staying hot.
I understand the fault light only has to do with the water heater in LP mode.
why would the light be on in electric mode?
Thanks
John

Here is the manual in case you don't have one. http://manuals.adventurerv.net/Atwoo...-93755-10E.pdf .I have heard of the red light coming on in elec mode when the system goes into lock out mode when the water gets to hot. I have spoken to the Attwood techs in the past and found them to be helpful. If nothing else happens this weekend, try them Monday 574-264-2131. Good luck

On page # 7 in the manual I posted is examples of some of the switches. Mine is # 11.

John,

We had the lockout lamp come on while on electric too. I flushed the tank and re-established the air gap (should be done at least twice a year), and I also cleaned up all the electric connections (there may be a sticker on your heater saying to use a pencil eraser to clean the control board contacts). One or the other cleared the condition and we have not had the light come on since. But now a year later our water is on the hot (too hot) side again which would mean the Thermostat / ECO is going. I'm waiting to see what it does when we leave FL, our water heater is in full sun all day which could be part of the problem. We have an Atwood GC10A-4E water heater which we usually have on 24/7 in the electric mode unless boondocked somewhere. I do make sure to run it on gas at least once a month.

Also, two very important points. Replace the drain plug if it is the original. It is always good to have a spare on hand when flushing the tank and make sure that the heater is off, never have the electric on when you empty the tank.

The light is above the water heater LP rocker switch and is marked fault. I have discovered on the forum it is the DSI (Direct Spark Ignition) fault light and is a safety feature. If the heater doesn't light after 3 trys on propane, it locks out the LP and you have to reset and try again. It only pertains to LP but will function in the electric mode if the water gets to hot.
My reset and works fine now
