Ferroli Domiproject F24 Flow Detector Ref. 33900029
If no hot water comes out when you turn on the tap, you may need a Ferroli Domiproject F24 Flow Detector. This part, also known as a flow switch or flow meter, is responsible for detecting the flow of water and activating the ignition to produce domestic hot water. When it fails, the system cannot heat the water, resulting in a lack of hot water supply. It is installed in boilers such as the Domiproject F24, Domiproject F24 D, DOMICOMPACT F24, DOMIcondens F24 D, and FER EASY C24, among others. It is recommended to replace it when the mentioned symptom occurs.

How to check if ref. 39818551 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 39818551. 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 flow meter 39818551 resolves.
The flow meter detects the passage of water to activate the domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
There is no hot water coming out of the tap even though the boiler is working fine.
Cause: The flow detector does not detect the passage of water and does not notify the electronics to start the burner.
Make sure that the tap provides a normal flow and not just a simple drip, because a very low flow may not activate the detector.
- 02
The burner does not ignite when opening hot water, but it does when heating.
Cause: This component only operates in the domestic hot water circuit, which isolates the fault to that specific function.
Try opening several taps in the house to rule out that it is a specific issue with a single point of consumption.
- 03
The burner ignites with a delay or intermittently when requesting hot water.
Cause: If the internal mechanism of the detector is jammed or dirty, it takes longer to react to the flow of water.
Check for visible limescale deposits in the area of the sensor before declaring it faulty.
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.
