Why is my A.O. Smith Water Heater not producing enough hot water?
- SSarah OneillJul 29, 2025
There could be several reasons for this. The power supply to the heater might not be on, so check the disconnect switch. The thermostat might be set too low. The heater might be undersized, so try to reduce hot water use. Incoming water might be unusually cold, especially in winter, so allow more time for the water to reheat. There could also be leaks from pipes or fixtures, so have a plumber check for repairs. Finally, the high-temperature limit switch may be activated; contact your dealer to determine the cause.
