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 does not enter the circuit when opening the filling valve.

  Cause: The valve is blocked or the shutter is not lifting, preventing the mains water from reaching the circuit.

  Make sure that the shut-off valve of the house is open before considering that the filling valve is faulty.

• 02

  The pressure increases slowly even though it is not being filled.

  Cause: The valve does not seal properly and allows a trickle of water to pass from the network.

  Close the main water supply valve and check if the pressure gauge stops rising to identify the problem.

• 03

  Water is leaking from the cap or the area of the threaded fitting.

  Cause: The gasket of the plug or fitting has lost its seal and water is leaking.

  Tighten the fitting carefully and dry the area to see if the dripping returns before replacing the part.

• 04

  The cap is hard or difficult to turn.

  Cause: The residues and limescale from the water have jammed the plug mechanism.

  Try to carefully uncover it and check if there is any visible limescale buildup on the thread before replacing it.

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.
