If your A.O. Smith Water Heater shows error F07 (flame detected after gas valve closed), it indicates: * Defective gas valves: Check for burner pressure and flame presence after the gas valves have closed. If either is present, the gas control must be replaced.
Why does my A.O. Smith Water Heater show F05 error?
If your A.O. Smith Water Heater shows error F05, indicating too many flame errors, it could be due to: * Incorrect roof or wall conduit causing recirculating flue gases: Check that the correct roof or wall flue conduit has been fitted and that it discharges into a permitted area; install the correct conduit if necessary.
What does S05 error mean on A.O. Smith Cyclone BFC - 30 Water Heater?
If your A.O. Smith Water Heater displays error S05, indicating an open circuit from dummy 2, it may be due to: * Dummy not correctly connected: Connect the dummy sensor leads to JP4. * Defective dummy: Replace the dummy sensor.
Why is my A.O. Smith Water Heater leaking?
If you notice water leaking from your A.O. Smith Water Heater, there are several potential causes: * A loose water connection: Try tightening the threaded connection. * Condensate leakage: Ensure the condensation water discharge is working correctly. * Leakage from another nearby appliance or pipe: Trace the source of the leak. * Leakage from the tank itself: Consult the supplier or manufacturer.
What causes F06 error on A.O. Smith Cyclone BFC - 30?
If your A.O. Smith Water Heater shows error F06 (short circuit between flame probe and earth), the problem might be: * Damaged cable in contact with metal surface: Check the wiring of the flame probe and replace it if necessary. * Broken/cracked ceramic part of the flame probe: Inspect the ceramic part of the flame probe near the burner's air distribution plate. If it's damaged, replace the flame probe.
How to resolve S03 error on A.O. Smith Cyclone BFC - 30?
If your A.O. Smith Water Heater displays error code S03, indicating an open circuit in sensor 2 of temperature sensor T1, it could be caused by: * Sensor not correctly connected: Connect the sensor lead to JP5. * Damaged cable or defective sensor: Replace sensor T1.
What does S02 error mean on A.O. Smith Cyclone BFC - 30?
If your A.O. Smith Water Heater is showing an S02 error, indicating an open circuit in sensor 1 of temperature sensor T1, it could be due to: * Sensor not correctly connected: Connect the sensor lead to JP5. * Damaged cable or defective sensor: Replace sensor T1.
How to fix S01 error on A.O. Smith Cyclone BFC - 30 Water Heater?
If your A.O. Smith Water Heater displays the error S01, indicating an open circuit from temperature sensor T2, it could be due to: * Sensor not correctly connected: Connect the sensor lead to JP3. * Damaged cable or defective sensor: Replace the sensor.
What does F01 error mean on my A.O. Smith Cyclone BFC - 30?
If your A.O. Smith Water Heater is showing an F01 error, which indicates a defect in the power supply circuit, here are potential causes and solutions: * Live and neutral connected incorrectly: Ensure the live and neutral wires are correctly connected, as the appliance is phase-sensitive. * Condensation on the flame probe: Disconnect the lead at the flame probe, ignite the appliance three times with an interrupted ionization circuit, reconnect the lead, and ignite again to evaporate condensation. * Floating neutral: Install an isolating transformer; contact your installation engineer for assistance.
How to troubleshoot F03 error on A.O. Smith Cyclone BFC - 30?
If your A.O. Smith Water Heater shows error F03, indicating the pressure switch isn't working correctly, it could be due to: * Damaged wiring/Open circuit: Check and replace the wiring between the pressure switch and the controller if necessary. * Pressure switch not closing: Check the fan speed, ensure hoses on the pressure switch and air supply hose are correctly fitted and not cracked, verify the flue gas outlet is compliant, check for blockages in the flue gas and condensation water discharges, and measure the pressure differential across the pressure switch. Clean the heat exchanger if the pressure differential is insufficient; otherwise, check the pressure switch with a multimeter.
