Hot water tank works fine on electric but not on propane. Tries to light 3 times and then goes into DSI Fault.
I can hear the solenoid click and smell gas but no spark at the ignitor / sensor. Removed it, cleaned and reset the gap, same problem. Removed the wire harness from the main board and cleaned the contacts, same results.Replaced the ignitor / sensor (checking the gap again) and same problem.
Then I used a grill lighter to manually light the gas (just to be sure I was getting gas). Fires right up but only burns for about 3 seconds and then the solenoid cuts off the gas.
My guess is the board isn't sending voltage to the ignitor (or it thinks it is but isn't) and when I light it manually the board isn't sensing the flame to keep the gas flowing.
I think it must be the board. Am I missing something?
