Fime Smoke Extractor for Ariston AS 24 FF - Ref. 65104357
If your boiler does not ignite or gets blocked due to a flue gas evacuation fault, you may need the Fime flue gas extractor for Ariston AS 24 FF - Ref. 65104357. This fan is responsible for evacuating combustion gases and creating the necessary draft for the boiler to start. When it fails, it can generate fault codes such as 6 04, 6 12, or 6 08, which indicate problems with the fan speed or the flue pressure switch. This extractor is compatible with models such as AS 24 FF, BS 24 FF, and Clas 24 FF, among others. It is recommended to replace it when it shows faults that affect the evacuation of flue gases.

How to check if ref. 65104357 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 65104357. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the extractor 65104357 resolves.
The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not start or locks up right when trying to ignite.
Cause: The extractor does not generate the minimum depression that the air pressure switch needs to allow the gas to flow.
Check that the impeller is not jammed by turning it by hand with the boiler unplugged.
- 02
The fan makes noise or vibrates noticeably when spinning.
Cause: A worn bearing or a dirty and unbalanced impeller causes vibration when rotating.
Check for dust or grease on the blades; a cleaning may solve it without replacing the part.
- 03
The display shows an extraction fault or a lack of draft.
Cause: The fan does not maintain sufficient airflow during operation due to wear on the motor or the impeller.
Check the flue and the smoke outlet terminal for any obstructions before replacing the extractor.
- 04
The boiler is not properly venting combustion gases, with odor or moisture in the area of the exhaust pipe.
Cause: The fan rotates but with insufficient flow, and it does not properly expel the gases to the outside.
Check that the flue pipe does not have crushed or poorly fitted sections before blaming the extractor fan.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 6 04 | Insufficient fan speed. | The flue gas extractor is operating below the setpoint or is not delivering a tachometer signal (Hall sensor). Check the RPM reading and Hall signal in diagnostics, and measure the power supply to the fan. |
| 6 12 | Fan fault. | Fault of the extractor itself (winding/blockage) or absence of tachometer signal detected by the PCB. Check that it receives 230 V and that the Hall sensor generates pulses/RPM in diagnostics. |
| 6 08 | Flue pressure switch open with the fan running. | If the extractor does not generate sufficient depression, the pressure switch does not close and the error appears. Check the closure of the pressure switch with a U manometer and ensure that the fan reaches nominal RPM/flow rate and is not obstructed. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
