hot water heater element
We previously posted about our hot water heater only working on gas. I spoke with someone that said it is one of three things, Signal from the board, a bad relay, or the electrical element. She said the relay and element are in the black plastic box next to the water heater inside the MH. I took a photo of it. Anyone know how to open the box? There seems to be a slit I can stick a screw driver in to take the cover off but the plastic pipes are so close to it. I'm assuming this is the box because I don't see anything else. Thank you in advance for any ideas you all may have.
