How to check if ref. S1007000 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

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 that require diagnosis in the filling valve S1007000

The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  I can't turn the filling key, the control is loose or slips.

  Cause: The extension is cracked or worn inside and does not transmit the rotation to the key.

  Check if the extension rotates freely on the key before considering it broken; sometimes it just needs to be properly reattached.

• 02

  I can't reach the filling key to open or close it; it's hidden in the boiler's gap.

  Cause: The extension extends access to the valve in boilers where it is recessed.

  Check that the extension is fully inserted before forcing it; a poor fit also prevents it from turning.

• 03

  I can't tell if the valve is open or closed.

  Cause: The pictogram on the extension is the only visual reference for the position in these models.

  Mark the open and closed positions yourself with a marker before changing the part just for this.

• 04

  The extension has broken, and a piece remains inside the housing.

  Cause: The plastic of the extension is the weakest part and breaks before the metal key when forcing the turn.

  Try to extract the rest with fine-tipped pliers before declaring the internal key as damaged.

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.
