Ferroli Bluehelix PRO 32C Flow Meter Ref. I39846130
The Ferroli Bluehelix PRO 32C flow meter, with reference I39846130, is a flow detector that is responsible for detecting the flow of water when a tap is opened, thus activating the ignition to produce domestic hot water (DHW). If this part fails, you will notice that hot water does not come out even when the tap is open. It is compatible with boilers from the Bluehelix PRO range, including models such as Bluehelix PRO 25C and Bluehelix PRO 32C, among others. It is recommended to replace the flow meter when you experience a lack of hot water when opening the tap.

How to check if the ref. I39846130 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 I39846130. 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 I39846130 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
You turn on the hot water tap and the boiler does not start the production of domestic hot water.
Cause: The flow detector does not send the water flow signal and the PCB does not activate the domestic hot water mode.
Measure the flow rate at the tap and make sure it is the normal one for the house before considering changing the part.
- 02
The hot water is fluctuating, coming out hot and cold alternately without changing the faucet.
Cause: The signal from the detector fluctuates due to internal dirt, and the boiler modulates the flame according to that irregular signal.
Test another faucet in the house to see if the pull happens the same way, so you can rule out that it's an issue with that specific outlet.
- 03
In heating mode, the boiler works without any issues, but it fails only when requesting hot water.
Cause: The flow detector operates only in the domestic hot water circuit, which is why the fault does not affect the heating.
Check that the fault occurs every time you open a tap and never when the heating is running alone.
- 04
The display shows a warning or code associated with the flow sensor.
Cause: The control unit receives an unexpected reading from the sensor and alerts or locks the equipment.
Note the code as it appears and compare it with the manual before assuming that this is the part.
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.
