Saunier Duval Themafast F 25 E H Extractor MOD Fime L25X0E13/01 Ref. S1073600
When you open the hot water tap, the Saunier Duval Themafast F 25 E H MOD Fime L25X0E13/01 Ref. S1073600 extractor activates to expel combustion gases and allow the boiler to start. If this part fails, you will notice that the boiler does not ignite or gets locked due to a flue gas evacuation problem, which may manifest with the fault code F2: Safety lack of draft/flue gas evacuation. It is compatible with models from the Themafast range, such as the Themafast F 24 E, Themafast F 25 E, and Themafast F 25 E H-MOD, among others. It is recommended to replace the extractor when you experience ignition or locking issues in the boiler.

How to check if the part S1073600 is the one 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 S1073600. 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 S1073600 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 tries to start, the fan activates and stops before the flame appears.
Cause: The flue gas extractor does not reach the required minimum speed and the boiler shuts off the ignition for safety.
With the boiler disconnected, check that the turbine turns smoothly by hand; if you notice resistance or noise, the problem is with the extractor.
- 02
The unit locks with a flue or smoke fault code shortly after turning on.
Cause: The boiler control checks that the fan is rotating correctly before allowing the gas to flow and blocks it if it does not detect it.
Check the flue duct (concentric pipe or outlet) for any total or partial blockage before replacing the fan.
- 03
A different beeping or buzzing sound is heard when the extractor is running.
Cause: The extractor motor has bearings that wear out over time and generate that additional noise.
Check if the noise changes when you gently touch the casing of the extractor: if it is constant, it is more likely to be the bearing.
- 04
The boiler stops during operation and not always at the same point in the cycle.
Cause: A loss of revolutions of the extractor while in operation causes the control to interpret a flue fault and cut off the service.
Check the electrical connections of the extractor (make sure the connector is properly fitted) before assuming that the motor is faulty.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F2 | Safety lack of draft/flue gas evacuation (air fault/pressure switch). | If the extractor S1073600 does not start or does not provide sufficient flow, the flue pressure switch does not close and the PCB enters SFT showing F2. Check voltage to the fan and that it rotates, depression in the venturi, and closure of the pressure switch. |
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.
