DSI fault light on water heater

[Toofun]

Our DSI fault light is coming on when trying to ignite our hot water heater by electric. Everything seems to be working properly. Our owners manual says the light will come on if attempting to light the heater with gas and for some reason it isn't lighting??

Check to be sure the gas mode switch is not bad. Secondly, I would clean connections on the DSI control board as well as the burner/venturi and igniter.

Go outside and observe the heater itself, with the access door open. See if it lights and goes out, or simply fails to light at all. Let us know what happens.

I had the same problem with our Tioga years ago- I just went out and pulled apart some connections at the control board and plugged them back in...all worked again- so follow what Roamer and Wizard say.

My atwood WH still has a placard on it that says to do just that before doing any other trouble shooting and replacing the module.
