  If your A.O. Smith Water Heater isn't producing any hot water, here are a few things to check: * First, ensure the unit has power by checking for blown fuses or tripped breakers and restore power if needed. * Second, verify that the unit is not in Vacation mode. If it is, press the Mode/Enter button to return to your preferred operating mode. * Third, the high temperature limit switch might be open. In this case you should reset the high temperature limit switch. * Fourth, your hot water usage might be exceeding the heater's capacity in the current mode. Try changing to a different mode or adjusting your usage habits. * Fifth, a non-functioning upper temperature sensor could be the cause. If this is the case, contact a qualified technician for service.

  High operation costs for your A.O. Smith Water Heater can stem from several factors: * A temperature set-point that is too high. Decrease the set point temperature. * A dirty air filter. Clean the air filter. * Having electric mode selected. Change to Efficiency or Hybrid mode to cut down on energy costs. * Reversed water connections. Make sure the cold connection is at the bottom and the hot connection is at the top. * Heat loss through exposed pipes. Insulate any exposed piping. * Hot water leaks.

Why is my A.O. Smith Hybrid ElectricHeat Pump Water Heater's Temperature & Pressure Relief Valve dripping?
- C
  Christie FaulknerAug 18, 2025
  A drip from the Temperature & Pressure Relief Valve on your A.O. Smith Water Heater may be due to: * Excessive water pressure. Check the water supply inlet pressure; if it's higher than 80 PSIG, install a pressure reducing valve to bring it down to the recommended 50-60 PSIG. * If you have a closed system, you might need to add or service a thermal expansion tank. * A non-functioning Temperature & Pressure Relief Valve. Replace the Temperature & Pressure Relief Valve.
