You mentioned that 12 volts is still getting to the relay even when the switch is off. Odds are the switch is bad, which is easily checked with a volt meter. If the switch is bad and kept constant voltage on the relay, the heating element could have been destroyed if there was no water in the tank. I would replace the switch.

got around to changing to changing the relay, switch and wire. Before dissembling the element I wrote how the wires are placed. Same with switch. Can't get it to work. I get power to the relay. The hot and neutral wires before the whole assembly. On the switch no light. I accidentally put the wrong wire on the switch and popped a fuse so something is going there. I also took a picture of the switch before removing wires and know that's right. I flipped the switch around after thinking it was upside down. I even swapped switches with pump. On the relay with switch on, I get nothing touching the terminals with my tester. I tried old relay nothing. I did buy a new relay and trying this again tomorrow.
The way its wired is one wire from power ,hot, is connected to one side of element. The neutral goes to relay and then to element. One yellow I'm assuming 12v goes to relay and assuming green is ground goes to relay. I swapped those two thinking maybe relay is made differently but it's the exact same.....at a loss now
