Today I was called to troubleshoot no power to the water heater. I tested for power at the disconnect, the splices on the water heater, and the connection points inside the water heater. 240 volts are present at all locations. I then tested continuity on the two heating elements and found the lower one to be bad. I recommended calling a plumber to replace the element. Thank you for having me into your home today and giving Mr Sparky the opportunity to earn your business. Tom Leonard
