DSI fault

I keep getting a DSI fault light coming on when using my waterheater. It will heat up the water just fine on electric, gas or both. I have put the switch on electric only and get the fault, I can put in on gas and get the fault. I can put it on both together and get the fault. Does not matter how I run in I still get the fault light to come on. The water still heats up, but after awhile it does start to cool down. It sometimes takes the light a while to come on. Anyone got any suggestions on what to look for ?????

    I know the water does get very very hot. It will burn you if you are not careful. I can't find a thermostat to turn it down. I think it is an atwood. I will have to check the manual.

    You might be getting the water too hot and that would cause a lockout condition and make DSI light go on...Is it an Atwood?...their manuals are online.

    Clean contacts on circuit board.
    Clean ground connection on the gas valve.
    Clean and check clearance of the flame sensor.
    Clean burner tube.
    Check connections on the ECO and the thermostat. Look for dark connections on ECO and thermostat. If any are visible replace both.
