  First, check the breaker, fuses, and the water heater's on/off switch to ensure the A.O. Smith Water Heater is receiving power. Then, make sure the hot water supply valves to your fixtures are open. If the issue persists, the operating set point may be too low, or the differential setting too high, so try adjusting these. Also, check and adjust the Temperature Probe Offset setting. Colder incoming water temperatures may also lengthen the time required to heat water to desired temperature, so allow additional time for heating. Check for any hot water piping leaks or open faucets. Finally, sediment or lime scale accumulation may be affecting water heater operation, so cleaning the sediment or lime scale accumulation may help.

Why A.O. Smith GDHE-50 is starting and operating roughly?

  Rough starting or operation of your A.O. Smith Water Heater can stem from several gas-related issues. It could be due to an undersized supply gas line causing low gas volume, low gas pressure, excessive supply gas pressure, or excessive manifold gas pressure. Using the incorrect fuel type can also cause this problem. Furthermore, vent gas recirculation at the vent and intake air pipe terminations on Direct Vent installations, excessive lengths of intake air and/or vent piping, clogged wire screens, or a clogged main burner might be the cause. Because of the complexity of the issue, it is best to contact a qualified installer or service agency for installation and service.
