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.

1. 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.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. 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

  You have to fill the heating circuit more often than usual.

  Cause: The valve does not close properly and allows water to leak slowly, even when closed.

  Close the valve to the maximum and mark the position of the knob; if it has turned by itself the next day or if pressure is still lacking, the valve is not sealing.

• 02

  Water is leaking from the filling valve area, even if it's just a small amount.

  Cause: The body of the valve or the connection with the pipe has lost tightness over time.

  Dry the area with a cloth, wait a few hours, and check if the dripping returns before replacing the part.

• 03

  It is difficult to open or close the valve, or it gets stuck halfway.

  Cause: The mechanism has seized up due to water deposits in the circuit, which is common if the valve has not been used for a long time.

  Try to move it gradually, without forcing it; if it gives a little but still doesn't close completely, it might just be accumulated dirt.

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.
