DSI only water heater left on?

[zorky]

Should I leave my DSI switch on while camping or only turn it on when we need hot water for showers? I have been leaving it on and probably should not. I have burned up 1 board I thought was due to lightning storm and one because my wife accidently left it on while parked at home. There was water in the hot water tank but it fried the board. Was wandering if anyone else has DSI propane only and leaves theirs on the entire time camping.

It's only on when we're around the camper.
When we leave or go to bed, we turn it off.
Water stays hot a long time.

On my last two campers, I've always left mine on. It shouldn't be burning boards. The only problem I ever had was last year when it was new, it failed to light a couple times and lit up the fault light. I just had to remove and reinstall the igniter and haven't had a problem since. I think it was just aligned a little off.

I leave mine on all the time when at a CG, never had a problem but I'm also 30 amp, so running the A/C and hot water tank on electric I would pull about 28 amps if both came on at the same time. I really doubt if your board problem was related to leaving it on, as much a malfunction with the spark igniter......

I normally turn mine off at night or if I'm leaving the rig (when camping) for any length of time. With that said I don't believe it does any harm to leave it on (not when stored of course)

I always turn mine off after we are finished using any hot water. As mentioned water stays pretty warm for a long time especially during summer months. Later RJD

I always turn mine on when we get to the campsite.

I turn off the switch on he WH and the circuit breaker when leaving and packing up when DW is finished cleaning inside.

Not using any propane while traveling this way and it only takes 30 minutes of their electricity to get hot water, AFTER insuring there is no air in the lines so the WH is full. this prevents burning out the electric heating element

The way I solved that problem is to use Campground Showers !!!
LOL !!!

There are several threads here about leaving WH on or not !!!

Found the solution to the cause. Suburban says there is a defect in the boards with a Q3 chip in which mine has had. They will replace them for free with a different type.

Suburban is aware of an issue of the Q3 component on some water heater module boards that was caused by the manufacture of said component. Suburban is warranting a replacement module board (using CNE board) and filing warranty with the manufacture of the module board.
