Filling Key Ferroli Domi Projet F 24 D Ref. 39819560
The filling valve Ferroli Domi Projet F 24 D is the part that allows water to be replenished in the heating circuit, which is essential for maintaining the proper pressure. When it fails, the user will notice that they cannot refill the circuit or that the valve is continuously leaking water, which causes an increase in pressure. This valve is compatible with several boilers in the Domiproject range, such as the Domiproject F 24 and the Domiproject C 24, among others. It is recommended to replace it when it shows leaks or does not function properly.

How to check if ref. 39819560 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 39819560. 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 and faults that the filling valve 39819560 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 is leaking right from the area of the blue lever, not where the pipe connects.
Cause: The internal closure of the valve does not seal properly and allows water to flow continuously.
Check if the moisture is coming from the lever or the upper connection before replacing it.
- 02
When opening the filling valve, no water or very little water enters.
Cause: The internal passage of the valve may be blocked by limescale, or the supply valve feeding it may be closed.
Check that the main shut-off valve before this filling valve is open.
- 03
There is a leak at the thread where the pipe connects, not in the body of the valve.
Cause: The gasket or Teflon of that connection has deteriorated, which is different from a fault in the valve itself.
Tighten the connection with the appropriate tool and check the condition of the gasket before replacing the entire valve.
- 04
The lever becomes stiff or stops halfway, especially if it hasn't been used in months.
Cause: Accumulated scale in the mechanism after a period of disuse, common at the end of summer.
Try moving it several times with the boiler cold to see if it gets freed before considering it stuck.
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.
