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 fill the circuit but the needle on the pressure gauge doesn't move

  Cause: The valve may be blocked or the gasket is not sealing, preventing water from entering the circuit.

  Check that the main network valve is open and that the filling hose or connection is not pinched or bent.

• 02

  A small puddle appears under the boiler right in the area of the filling valve.

  Cause: The washer of the valve wears out with use and allows water to pass through, even when it is closed.

  With the boiler off, dry that area well and check a few minutes later if the dripping reappears.

• 03

  The valve turns very stiffly or seems jammed when trying to open it.

  Cause: Sediments and limescale from the water can seize up the internal mechanism if it is not handled for a long time.

  Before forcing it, try a gentle and gradual turn; forcing a stuck valve can break the plastic body.

• 04

  After refilling, the pressure keeps rising on its own without you opening anything.

  Cause: The closing mechanism does not seat properly and allows a small flow to pass continuously.

  Close the valve tightly and note the pressure; check it again after 15 minutes without touching anything else.

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.
