I was called for a hot water tank not working that had within 5% adequate voltage at the 4500 watt element, and 18 amp draw....still no hot water, just warm. The plumber changed the controls and elements, still same problem. I checked the resistance on the element at 13 ohms... seemed about right. With power at element, seemingly right resistance, why no hot water?
