Caleffi Flow Detector for Cointra Domitop F 24 E Boiler
The Caleffi flow detector for the Cointra Domitop F 24 E boiler is responsible for detecting the flow of water when a tap is opened, thus activating the ignition for the production of domestic hot water. If this part fails, you will notice that hot water does not come out even with the tap open. This detector is compatible with several boilers, including models such as the Domitop DGT C24E and the Domina F 24 E, among others. It is recommended to replace it when the mentioned symptoms occur, thus ensuring the supply of hot water.

How to check if the ref. 39830570 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 39830570. 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 39830570 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
The boiler does not ignite the burner even though water is circulating through the circuit.
Cause: The detector is not closing the contact that alerts the PCB that there is flow, so the control unit does not authorize the ignition.
Make sure that the detector is installed with the flow arrow in the correct direction of the water.
- 02
The boiler shuts down suddenly while running, as if it loses water all of a sudden.
Cause: An intermittent flow reading causes the PCB to believe that the water has stopped circulating and cuts off for safety.
Check for any dirt or limescale buildup on the internal paddle of the sensor before replacing it.
- 03
A warning for lack of water or flow is triggered even though the circuit is full and without leaks.
Cause: The flow detector is the one that informs the PCB of the actual circulation, and if it fails, it simulates a lack of water that does not exist.
Check that the circulation pump is running and pushing water before blaming the flow sensor.
- 04
The domestic hot water takes a long time to come out or doesn't come out properly, even though the tap is fully open.
Cause: In some installations, this same sensor also indicates the flow of water to activate the production of domestic hot water.
Check the mains pressure and the water inlet filter before declaring the detector 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.
