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 add pressure more often than usual.

  Cause: The valve allows water to flow even when it is closed, thus compensating for the pressure loss in the circuit.

  Close the valve tightly, note the pressure of the boiler, and check if it increases by itself in the following hours.

• 02

  You notice humidity or dripping in the area of the valve.

  Cause: The sealing gasket has deteriorated and allows water to pass through the body or the fitting.

  Dry the area and locate the exact point of the leak before considering that the valve is faulty.

• 03

  The knob does not turn or is broken, and you cannot open or close the valve.

  Cause: The plastic of the knob wears out with use until it breaks.

  Carefully check if the metal shaft rotates on its own to confirm that the issue is only with the knob.

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.
