Why A.O. Smith FPSH Water Heater has not enough hot water because of thermostat problems?
If your A.O. Smith Water Heater isn't producing enough hot water due to thermostat issues, first, ensure the thermostat isn't set too low by turning the temperature control higher. If the issue persists, the thermostat or ECO may be defective and require replacement.
Why is my A.O. Smith FPSH Water Heater leaking from the T&P valve?
If your A.O. Smith Water Heater is leaking from the T&P valve, it could be due to thermal expansion in a closed water system. To resolve this, install a thermal expansion tank, and do not plug the T&P valve. Alternatively, the valve might be improperly seated, so check the relief valve for proper operation, again ensuring not to plug the T&P valve.
What to do if A.O. Smith FPSH Water Heater has not enough hot water?
If your A.O. Smith Water Heater is not providing enough hot water, consider these factors: the heater might be undersized, so reduce hot water usage. Low gas pressure could be a factor, so contact your dealer. If the incoming water is unusually cold, allow more time for the heater to reheat. Also, check for leaking hot water pipes or fixtures and have a plumber repair any leaks.
Why is the water from my A.O. Smith FPSH Water Heater too hot?
If your A.O. Smith Water Heater is producing water that is too hot, it may be because the thermostat is set too high. Refer to HIGH TEMPERATURE REGULATION for instructions.
Why is my A.O. Smith Water Heater leaking water?
If your A.O. Smith Water Heater is leaking water, it could be due to improperly sealed hot or cold supply connections, relief valve, drain valve, or thermostat threads. Try tightening these threaded connections. It could also be due to leakage from other appliances or water lines, so inspect other appliances near the water heater. Finally, condensation of flue products could be the cause, so refer to the “CONDENSATION” section.
What causes sooting in my A.O. Smith FPSH Water Heater?
If your A.O. Smith Water Heater is sooting, it indicates improper combustion. Refer to AIR REQUIREMENTS on page 4.
Why does my A.O. Smith FPSH have hot water odors?
If you're experiencing hot water odors from your A.O. Smith Water Heater, which may relate to cathodic protection, it could be due to high sulfate or mineral content in the water supply.

To resolve this, cycle the external power or remove the request for heat for 2 seconds before reapplying.
How to fix A.O. Smith FPSH Water Heater when LED status is off?
If your A.O. Smith Water Heater's LED status is off, it indicates there is no power to the system control. Check for power to the heater, inspect the wiring harness for proper connections, and verify line voltage at the harness connectors.
