Manual Filling Valve for Boiler CONDENS F24E and Compatible Models – Ref. S1007000
It is the manual filling key of the boiler: it allows to refill the circuit with water and recover the operating pressure when it drops. The body is made of black plastic with a blue handle and a metal sleeve. It is operated manually and closes after filling. The replacement requires first confirming the fault of the part through technical diagnosis, even when it drips, does not close properly, or the handle gets stuck.

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.
- 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.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- 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
Water leaks from the valve when opening or closing the handle.
Cause: The gasket between the control and the metal sleeve is worn and allows water to pass when the control is activated.
Close the control fully, dry the area, and check if the dripping comes from the metal socket or the plastic body before replacing it.
- 02
The boiler loses pressure and the circuit needs to be refilled frequently.
Cause: This valve is only used for refilling, so a constant loss of pressure is usually due to a leak in the circuit, not from the valve at rest.
Close it properly after refilling and check if the pressure drops again in the following days without touching anything.
- 03
The blue knob or the metal sleeve is broken or difficult to turn.
Cause: The metal sleeve protects the threading, but the control is made of plastic and can break if forced while being stuck.
If it is difficult to turn, try gently in both directions; if it is already broken, check if the socket allows you to operate the mechanism with a tool before replacing the entire part.
- 04
It doesn't close completely after refilling, and water keeps entering the circuit.
Cause: The internal seat does not seal properly, either due to wear or due to the accumulation of scale between the control and the body.
Turn the control to the fully closed position and check if the water flow stops completely before replacing the valve.
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.
