A.O. Smith fault code? This is the part you usually need
Your A.O. Smith appliance is showing a fault code? Below you can see, for common codes, which part is usually the cause – ready to order.
| Fault code | What is going on | Part |
|---|---|---|
| 0A5 | The thermal fuse has interrupted the control circuit. | View thermostats |
| 045 | Damaged wiring and/or defective sensor. | View sensors |
| 78A | Bottom sensor fault | View sensors |
| 502 | Sensor fault: Sensor is not (correctly) connected. | View sensors |
| 503 | Sensor fault: damaged wiring and/or defective sensor. | View sensors |
| 504 | Sensor fault: damaged wiring and/or defective sensor. | View sensors |
| 787 | Top sensor fault | View sensors |
| 788 | Upper-middle sensor fault | View sensors |
| 789 | Lower-middle sensor fault | View sensors |
| E03 | The two temperature sensors in the tank measure a difference of > 10 ºC for at least 60 seconds. | View sensors |
| E04 | The two temperature sensors measure a difference of > 10 ºC for at least 60 seconds. | View sensors |
| Explosive ignition | Poor flame pattern: insufficient air supply | View burners |
| F01 | Control fault: Live and neutral were swapped during connection | View electrodes |
| F02 | Fan fault: damaged or loose wiring. | View fans |
| F02 | Defective motor and/or rotor | View Motor |
| F03 | Air pressure switch fault: the non-return valve between the fan and the burner is stuck. | View fans |
| F03 | Insufficient pressure difference at the air pressure switch, caused by: - the air supply and flue system - malfunctioning condensate drain - fouled burner - blocked heat exchanger | View heat exchangers |
| F04 | Three unsuccessful ignition attempts: no burner pressure | View burners |
| F04 | Three unsuccessful ignition attempts: fault in the glow igniter circuit | View electrodes |
