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

  Water leaks when turning the filling valve.

  Cause: The internal plastic closure does not fit properly when moved.

  Check if the leak occurs when moving the lever or if it continues to drip with the key still, to identify if it is the shaft seal.

• 02

  It doesn't seal after refilling and there is a continuous drip.

  Cause: The closing seat is worn out and does not completely stop the flow of water.

  Dry the body thoroughly, close it completely, and check after a few minutes if it becomes damp again.

• 03

  The handle of the valve is hard to turn.

  Cause: Sediments in the heating circuit have hardened the internal mechanism.

  Try to turn it gently; if it is completely stuck, do not force the handle before considering replacing it.

• 04

  The circuit pressure does not recover when trying to refill.

  Cause: The valve does not open completely or the internal passage is blocked.

  Check that the main water valve is open and that the filling hose is properly connected before considering the valve as faulty.

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.
