PROBLEMS WITH ELECTRIC WATERHEATERS ARE VERY EASY TO LOCATE AND REPAIR. FIRST DETERMINE IF THERE IS 240 VOLTS GETTING TO THE HEATER AT THE JUNCTION BOX ON THE TOP OF THE HEATER. BE CAREFUL AND USE A VOLTAGE TESTER . IF POWER IS NOT THERE THEN YOUR PROBLEM IS EITHER THE WIRE,FUSE OR BREAKER. IF YOU HAVE POWER THEN CHECK THE VOLTAGE AT THE TOP HEATER ELEMENT, IF YOU READ 240 VOLTS AT THE ELEMENT AND HAVE NO HOT WATER THEN THE TOP ELEMENT IS BURNED OUT AND HAS TO BE REPLACED. TO BE 100 % SURE IF YOU HAVE AN AMPMETER THERE SHOULD THE TO BE AN 18.5 AMP LOAD ON THE WIRE LEAD GOING TO A PROPERLY OPERATING ELEMENT. IF YOU DON'T HAVE BUT 120 VOLT AT THE ELEMENT THEN THE THERMOSTAT AT THE TOP OF THE HEATER IS SWITCHED TO THE LOWER ELEMENT AND IS PROBALLY DEFECTIVE AND NEEDS REPLACEMENT. AS A RULE OF THUMB I ALWAYS REPLACE THE THERMOSTAT WHEN I REPLACE AN ELEMENT.
