How to check if ref. S1007000 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 S1007000. 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 S1007000 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 valve drips when operated to refill the circuit.
Cause: The internal seal does not seal properly when the lever is moved, allowing water to pass intermittently.
Check if the leak occurs only when moving the lever or also when at rest; this will indicate whether it is the gasket or the shaft.
- 02
It continues to drip after filling, even with the valve closed.
Cause: The closing seat is worn out and does not completely stop the flow of water.
Dry the body, close it thoroughly, and check after a few minutes if the moisture reappears.
- 03
It is difficult to turn the lever; it needs to be forced.
Cause: The accumulated scale in the internal mechanism makes it difficult to turn over time.
Move the lever gently first; if it is completely stuck, do not insist before replacing it.
- 04
The pressure in the circuit does not recover when refilling.
Cause: The valve does not open completely or has an internal blockage.
First, check the network valve and make sure that the filling hose is not bent or improperly threaded.
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.
