If your Fer Boiler is showing a heating sensor fault, the sensor may be damaged. Replace the sensor.
Why is my Fer FERtech F 24 D Boiler showing a gas valve fault?
A gas valve fault in your Fer Boiler can arise from modulating operator wiring disconnected, requiring a check of the wiring. Alternatively, it might be due to a faulty gas valve, necessitating a check and potential replacement of the valve.
What to do if my Fer Boiler activates overtemperature protection?
If your Fer Boiler activates overtemperature protection, it may be due to a damaged heating sensor. Check the correct positioning and operation of the heating sensor. It could also be caused by no water circulation in the system, so check the circulating pump. Finally, air in the system can trigger this, so vent the system.
What to do if my Fer Boiler has poor combustion?
If your Fer Boiler is experiencing poor combustion, it might be due to an inlet/exhaust flue obstruction. To resolve this, check the flue.
What to do if my Fer FERtech F 24 D has poor combustion fault?
If your Fer Boiler shows a poor combustion fault, specifically if fault F20 was generated 6 times in the last 10 minutes, refer to fault F20 for guidance.
What to do if my Fer FERtech F 24 D Boiler supply voltage is under 180V?
If the supply voltage to your Fer Boiler is under 180V, it is due to electric mains trouble. Check the electrical system.
What should I do if my Fer FERtech F 24 D Boiler shows no flame after the ignition phase?
If your Fer Boiler shows no flame after the ignition phase, it could be due to low pressure in the gas system. Check the gas pressure. Another possible cause is the burner minimum pressure setting, so check the pressures.
What to do if my Fer FERtech F 24 D has faulty mains frequency?
If your Fer Boiler indicates a faulty mains frequency, it is due to electric mains trouble. Check the electrical system.
What does it mean if my Fer Boiler has a DHW sensor fault?
A DHW sensor fault in your Fer Boiler may be due to a damaged sensor. Check the wiring or replace the sensor. It could also be due to wiring shorted or wiring disconnected.
