Why A.O. Smith Water Heater has no hot water?
- R
  Rebecca BradfordJul 28, 2025
  If your A.O. Smith Water Heater isn't producing hot water, it could be due to a hot water supply valve being turned off. If you have Surface Mount Control Models, check the thermostat/ECO controls. For Electronic Control Models, verify the Operating Set Point and Differential Set Points. Also, for Electronic Control Models, make sure both enable/disable circuits at the CCB’s J7 plug/socket connection are closed circuits.

  If your A.O. Smith Water Heater is tripping the breaker, ensure that the power supply breaker/fusing to the water heater meets the minimum required fuse/wire/breaker sizing, referring to the voltage and amperage listed on the water heater rating plate. Also, verify that the internal power supply phase wiring is configured correctly. Check for any pinched or shorted wiring, whether it's internal or in the power supply wiring.

What to do if A.O. Smith Water Heater shows 'No Current Detected'?
- J
  Justin MeyerAug 10, 2025
  If your A.O. Smith Water Heater displays a “No Current Detected” alert, first ensure the power supply to the water heater matches the voltage listed on the rating plate. For 3-phase models, check for a dead leg of power. Also, check the power circuit fuses, heating elements, and contactors. Inspect the power circuit wiring to heating elements from the Power Distribution Block, to fuse blocks, to contactors, to heating elements, referring to the wiring diagram and Contactor Configuration illustration. Correct any miswiring and repair or replace damaged wiring as needed. Check the Element Sensor J12, J13, J14 plug/socket connections at the CCB for wear or damage, ensuring they are properly connected. Finally, check the Element Sensors themselves and replace any that are defective.

- J
  James McgrathAug 15, 2025
  If your A.O. Smith Water Heater is showing an 'Energy Cut Out (ECO)' fault, check the J5 plug/socket connections at the CCB to ensure they are properly connected. Check the ECO continuity and for 120 VAC to and from the ECO. Replace the Immersion Temperature Probe if the ECO switch contacts remain open at normal operating temperatures. Also, inspect the water system piping to ensure no external heat sources are adding heat to the water inside the water heater.
