Ferroli Divatop Low NOx Pressure Sensor F32 Ref. 3640210/0
In the Ferroli Divatop Low NOx F32 boilers, the pressure sensor 3640210/0 measures the water pressure in the circuit and sends the information to the control board. If this part fails, you may notice incorrect readings and lockouts due to false low pressure, which can generate fault codes F37 or F47. This component is compatible with other models in the Divatop range, as well as with some from the Joannes series. It is recommended to replace it when experiencing pressure issues or related errors.

How to check if ref. 39818770 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 39818770. 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 pressure switch 39818770 resolves.
The pressure sensor measures the water pressure for the electronics. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler shows a pressure different from that of the glass manometer.
Cause: The sensor incorrectly interprets the water pressure and sends a wrong signal to the control board.
Compare the reading on the display with the physical manometer of the boiler before changing the sensor.
- 02
A pressure warning or fault code appears on the display without any visible leak in the circuit.
Cause: The sensor sends an incorrect signal even though the actual pressure in the circuit is correct.
Bleed the circuit and measure the actual pressure with the manometer; if it is correct and the fault persists, the sensor may be failing.
- 03
The pressure reading on the panel fluctuates on its own, without any intervention in the circuit.
Cause: Unstable electrical signal from the sensor, common when the sensor or its connection is deteriorated.
Check the connector of the sensor, clean it, and make sure there is no moisture or oxidation before replacing it.
- 04
The boiler locks out due to low or high pressure even though the circuit is properly filled.
Cause: The sensor provides an incorrect reading that the control unit interprets as out of safety limits.
If you can measure the actual pressure of the circuit externally, compare it with the display before replacing the part.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F37 | Incorrect water pressure in the installation | The water pressure transducer (39818770) may give an incorrect reading or fail; the PCB interprets low pressure and triggers F37. Verify by comparing the manometer vs display/diagnostic reading and checking the transducer connector/wiring. |
| F47 | Water pressure sensor anomaly in the installation | Loss of communication or interrupted wiring of the pressure transducer; the PCB detects a sensor fault and displays F47. Check continuity of the wiring and connector; if it persists, replace the transducer. |
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.
