Ferroli Divatop Low NOx F 32 Three-Way Valve
If you notice that you have hot water but no heating, or vice versa, it is possible that the 3-way valve is failing. The Ferroli Divatop Low NOx F 32 3-Way Valve, with reference 39820442, is responsible for directing water between the heating circuit and the domestic hot water circuit. When it shows anomalies, fault codes A09 or A16 may appear, indicating problems with the gas valve. This valve is compatible with models such as Divatop Low NOx F24 and F32, among others. It is recommended to replace it when it shows faults in its operation.

How to check if ref. 39820442 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 39820442. 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 3-way valve 39820442 resolves.
The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
There is no domestic hot water but there is heating, or vice versa.
Cause: The motor does not fully rotate the shutter, either due to wear or due to limescale buildup.
Listen for a brief buzzing sound from the motor when requesting hot water; if you hear nothing, check the wiring and the fuse on the PCB before the gas valve.
- 02
A metallic knock is heard when switching from heating to domestic hot water.
Cause: The coupling between the motor and the shaft is loose or worn, causing knocks with each change.
Check if the noise occurs consistently with each mode change; if it only happens sometimes, it may be air in the circuit and not the valve.
- 03
There is a water leak in the area of the 3-way valve, sometimes only when the boiler is on.
Cause: The body gaskets lose tightness due to cycles of heat and pressure.
Dry the area, turn on the boiler, and observe if the dripping occurs when switching modes.
- 04
The motor can be heard running, but the boiler still doesn't switch circuits properly.
Cause: The internal shaft may be broken or uncoupled from the motor, even if it is functioning correctly.
If the motor is running but the water mixture persists, it is a sign that the problem is internal mechanical and not electrical.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A09 | Gas valve anomaly | A problem has been detected in the gas valve. This may cause the boiler to not function properly. Check the status of the 3-way valve and its connection. |
| A16 | Gas valve anomaly | A problem has been detected in the gas valve. This may cause the boiler to not function properly. Check the status of the 3-way valve and its connection. |
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.
