As Bill suggested it can be the thermostat, mine failed after one year and Suburban replaced it (I did, they furnished it). Its located under the black plastic access cover out side just above the toggle switch. If it fails usually fails open acts a switch to element power when heater "turns on", opens when water is hot enough. There's sketches in your book, believe its on the left side of that panel where the DC thermostat is on the right. You need a voltage tester or a friend who has one to see if its defective. If water is still cold the thermo should be closed, if open its no good.
