How to check if ref. 39810850 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 39810850. 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 circulation pump 39810850 resolves.
The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler turns on but doesn't heat, as if the water isn't circulating through the system.
Cause: The pump motor does not start or the rotor is stuck and does not move the water.
Turn the shaft with a flat screwdriver in the front slot to see if it is free before replacing it.
- 02
Unusual noise or vibration noticeable when touching the pipe next to the pump.
Cause: There is air trapped in the pump or the bearing is worn and rubs when it rotates.
Bleed the air from the pump using the front screw and repeat the ignition cycle before replacing it.
- 03
Water is dripping from the pump shaft area.
Cause: The internal mechanical seal is worn and allows water to pass through slowly.
Dry the area well and check after a while if the dripping reappears right at the axis and not at a nearby joint.
- 04
The boiler locks out indicating a water circulation fault.
Cause: The control unit detects that the water is not circulating because the pump is not turning and shuts off for safety.
Confirm that the pump does not start at any speed before declaring it faulty; do not rely solely on the fault code.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F3 | The safety thermostat is activated. | If the circulation pump is blocked or faulty, or if there is air in the system, the water does not circulate properly, causing it to overheat and the safety thermostat to activate. Check if the pump is receiving power, if it is spinning correctly, its consumption, and if the circuit needs to be bled. |
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.
