Extractor Fan Saunier Duval Isofast F 30 E H-MOD Fime
If your boiler does not ignite or gets blocked due to a fault in the flue gas evacuation, you may need a Saunier Duval Isofast F 30 E H-MOD Fime extractor fan. This extractor evacuates the combustion gases and generates the necessary draft for the boiler to start. When it fails, you may notice symptoms such as fault codes F2, 02, or 10. This fan is compatible with several models, including the Themafast F 30 E, Isofast F 30 E H-MOD, and the Isotwin F 30 H-MOD, among others. It should be replaced when it shows any fault that affects its operation.

How to check if ref. S1072500 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 S1072500. 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 S1072500 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 extractor does not spin and the boiler does not ignite; it remains in standby or repeats attempts.
Cause: If the extractor does not rotate, there is no extraction for the pressure switch, and the control board does not allow the gas valve to open.
Before replacing it, check with a tester that power is reaching the motor; an extractor without power may seem faulty.
- 02
Vibration or rattling noise that can be felt even through the boiler casing.
Cause: An imbalance in the turbine, due to wear or dirt, causes vibrations in the motor-turbine assembly.
With the boiler off, manually move the turbine and check for play in the shaft; noticeable play indicates mechanical wear.
- 03
The display shows a fault code related to the extractor or the fan.
Cause: The PCB detects the signal from the fan and locks if it does not match what it expects at that moment in the cycle.
Reset the fault and observe if it reappears when starting the fan or later in the cycle: the timing helps to identify if it is the fan or another component.
- 04
The extractor starts normally but stops on its own, especially when the boiler is hot.
Cause: The accumulated heat can worsen the failure of a worn bearing or a winding with moisture, causing the motor to seize when hot.
Note whether the fault occurs always when cold, always when hot, or in both cases: if it only fails when hot, suggest thermal wear.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F2 | Air deficiency safety (airflow/air intake fault). | The faulty, blocked, or unpowered extractor (fan) does not generate the necessary depression, the pressure switch does not switch, and the boiler enters F2; check voltage to the motor, free rotation/noise, and switching of the air pressure switch. |
| 02 | Airflow safety (extraction/aspiration fault) in ISOFAST ranges F. | Extractor fault prevents correct airflow/smoke flow and activates safety 02; check power supply to the fan, ensure it rotates without friction, check the condition of pressure tubes and pressure switch, and ensure the duct is not obstructed. |
| 10 | Fan fault in ISOFAST ranges F. | Fault in the extractor (motor/wiring/tachometer) detected by the electronics; check power supply and signal return, motor continuity, and ensure the fan is not blocked. |
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.
