Our Sani-Con quit while traveling. The On/Off switch was exposed behind the panel (exposed to weather). I simply replaced the switch and coated it with weatherproof gel. Weatherproofing as explained by rmmpe would probably be better.By the way, our step starting going in and out on its own while traveling. Same problem. The switch on the door was exposed to weather. Same solution.
I should have told y'all our tanks and flushing valves were marked wrong. Don't you think that caused some confusion
