Why is my A.O. Smith 100 Water Heater making sizzling or rumbling sounds?
Sizzling or rumbling sounds in your A.O. Smith water heater are often caused by sediment or calcium buildup in the bottom of the tank. To resolve this, clean the sediment from the tank. Refer to the Draining instructions in the Maintenance section of the manual.
Why is my A.O. Smith Water Heater not producing enough hot water?
Several factors can cause an A.O. Smith water heater to not produce enough hot water. The heater might not be lit, or the thermostat isn't on. In this case, refer to the LIGHTING INSTRUCTIONS. The thermostat might be set too low (refer to TEMPERATURE REGULATION). The heater could be undersized, so reduce hot water use. Low gas pressure can also be a factor, so contact your gas supplier. If the incoming water is unusually cold, allow more time for the heater to reheat. Leaking hot water pipes or fixtures should be checked and repaired by a plumber. Finally, a high-temperature limit switch may have been activated, in which case you should contact a service technician.
Why does my A.O. Smith Water Heater pilot keep going out?
A pilot outage in your A.O. Smith water heater may be due to several reasons. The pilot burner might be dirty, so clean the pilot assembly. A thermocouple malfunction is another possibility, requiring replacement of the pilot assembly and/or thermocouple. A defective gas control could also be the cause, necessitating replacement of the gas control. Additionally, ensure the thermocouple tip is correctly positioned in contact with the pilot flame; if not, insert the thermocouple correctly.
What to do if A.O. Smith 100 Water Heater burner will not stay lit?
If the burner in your A.O. Smith water heater won't stay lit, it could be due to a thermocouple malfunction. Consider replacing the pilot assembly and/or thermocouple. Another potential cause is a defective gas control, which would require replacing the gas control.
Why is my A.O. Smith 100's T&P valve leaking?
A leaking T&P valve in your A.O. Smith water heater can occur due to thermal expansion in a closed water system. Install a thermal expansion tank to resolve this issue and DO NOT plug the T&P valve. It can also happen due to an improperly seated valve. Check the relief valve for proper operation, and again, DO NOT plug the T&P valve.
Why won't the pilot light on my A.O. Smith 100 Water Heater light?
