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

  The pressure does not rise when I open the filling valve.

  Cause: If the internal passage of the valve is blocked, water cannot enter the heating circuit.

  Before changing it, make sure that the water shut-off valve in the house is open and that there is pressure available at that outlet.

• 02

  I see drops on the body of the valve even though I am not handling it.

  Cause: A worn internal seal allows water to pass continuously.

  Dry the part, wait a few minutes, and check if moisture reappears on the body.

• 03

  I close the control but it keeps dripping, even if it's just a little.

  Cause: If the internal seal does not seat properly, there may be a minimal passage through which water continues to leak.

  Check that the control reaches the closing limit and that it is not obstructed by dirt or limescale.

• 04

  The water comes out with less force than usual when trying to refill pressure.

  Cause: A partial obstruction inside the valve reduces the flow rate, even though the mechanism is functioning.

  Check if the flow improves when fully opening the control or if it remains weak in any position.

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.
