I tried to use the electric option for the water heater this weekend.
The switch was turned on in the compartment (what a pain in the ass that is to get to........
When I turned on the 'water heater' button on the console in the trailer, I could hear it trying to work, but then the 'dsi flt' light came on. It tried about 3 times, that I heard, to 'work' but it did not and the light stayed on.
I shut off the electric option and switched it to gas; this also made the 'dsi flt' light come on, so I bled the lines.
Finally, it came on using gas.
I never tried it again on electric, (the pin in the switch you put in and take out was just too much of a PITA to do again to soon)
Any thoughts as to why it didn't work while on electric?
