Saunier Duval ThemaClassic F25E Drain Tap Ref. S1006300
The drain tap Saunier Duval ThemaClassic F25E is a filling valve that allows water to be replenished in the heating circuit to recover the necessary pressure. When it fails, the user notices that they cannot refill the circuit or that the tap continuously leaks water, which can lead to an undesired increase in pressure. This tap is compatible with various Saunier Duval boilers, such as the ThemaClassic C 24 E, ThemaClassic F 24 E, among others. It should be replaced when it shows leaks or does not allow the circuit to be filled.

How to check if ref. S1006300 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 S1006300. 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 filling valve S1006300 resolves.
The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The drain tap drips constantly even when it is closed.
Cause: The internal seat does not seal completely and allows water from the circuit to leak out.
Check that it is turned all the way to the closed position before declaring the part defective.
- 02
It is difficult to open it when it is necessary to drain the boiler for a repair.
Cause: The mechanism gets stuck due to limescale and because it has not been operated for a long time.
Try to open it with an appropriate key without excessive force; when cold, the body can break.
- 03
Water keeps coming out after closing the tap following the circuit drain.
Cause: The hose fitting or the internal seat is worn and does not properly cut off the flow.
Check if the drain hose fitting is tightened properly; sometimes the leak comes from there and not from the tap itself.
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.
