My question is how can I get the push button fuse/breaker for the hot water heater to pop out (off position). All power is disconnected on our boat as we're in the process of selling it. I was showing the prospective buyer how the button works. It was popped out and I pushed it in, thinking I could just push it again and it would spring pop out. But not happening. Surveyor wants shore power electricity tomorrow and I need the hot water heater to be off so it doesn't burn out without water. Does it somehow need power to pop out? Do I need to access the back of the panel to fix this? Or am I missing something? Thanks,k Kerk
