Saunier Duval Thematek SF 24 E Fime Extractor Ref. S1008800
The ThemaClassic range and the Thematek model include the Saunier Duval Thematek SF 24 E Extractor Fime Ref. S1008800. This part acts as a flue fan, evacuating combustion gases and generating the necessary draft for the boiler to start. If it fails, you will notice that the boiler does not ignite or locks out, displaying the fault code F3 due to obstruction in the flue gas outlet. It is compatible with models such as ThemaClassic F 24 E, ThemaClassic F 25 E, and Thematek F 24 E, among others. It should be replaced when these symptoms or fault codes are detected.

How to check if ref. S1008800 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 S1008800. 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 S1008800 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 ignite and shuts off after a few seconds.
Cause: The air pressure switch does not close because the fan does not provide sufficient flow, and the control board cuts off the gas for safety.
Before replacing it, check that the fan starts spinning as soon as the boiler starts and that it doesn't stop in the middle of the operation.
- 02
There is a buzzing or forced motor noise in the fan.
Cause: Bearing wear causes the rotor to rub and produce that continuous noise.
Listen to see if the noise changes in tone when you carefully touch the extractor casing: if it does, it points to the motor rather than the outlet pipe.
- 03
Flue gas evacuation fault or insufficient draft warning
Cause: Without the minimum depression that the fan must generate, the pressure switch does not close, and the boiler locks out for safety.
Check the external outlet terminal and the silicone tubes before assuming the part is broken: a blockage causes the same symptom.
- 04
The fan rotates slower than usual or doesn't rotate at all.
Cause: It points to a motor with either the winding or bearings already deteriorated, which does not reach the necessary speed.
With the boiler unplugged, turn the turbine by hand: if you feel resistance or it doesn't turn smoothly, confirm the mechanical fault.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F3 | The boiler stops due to obstruction in the flue gas outlet. | The boiler stops automatically due to a blockage in the flue gas outlet. If the fan is not working properly, it may not be expelling the fumes correctly. Check the condition of the fan to determine if it is the cause of the blockage. |
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.
