Hi. Can anyone let me know if I am way off base? I have a Rheem electric water heater that is over a decade old. It no longer provides any hot water. When I opened the upper panel and measured the voltage (touching the two terminals under the plastic cover), my digital multimeter showed only 80V. In addition, there is water on floor and the insulation itself is dripping water from the control panel. Is this heater likely totally done? I tried to measure the voltage directly on the terminals for the upper element instead sticking inside of the lugs on the top of the unit (I didn't pick up any voltage when i tried to do that). Thanks for any additional tips.
