How to check if ref. 39820902 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 39820902. 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 that require diagnosis in the circulation pump 39820902
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 the heating does not heat or takes a long time to do so.
Cause: If the pump is at the lowest speed or running weakly, the flow may not be sufficient for the circuit.
Check the speed at which the pump is set (selector on the body) before declaring it faulty.
- 02
There is noise or vibration in the pump, more noticeable at some of the speeds.
Cause: A rotor with scale or trapped air often vibrates more at certain speed positions.
Change the speed and bleed the air from the pump through the front screw before replacing it.
- 03
The pump does not start at any of the three speeds.
Cause: The motor may be jammed or not receiving power from the PCB, regardless of the selected speed.
Check that power is reaching the pump in all three positions of the selector before purchasing a new one.
- 04
The boiler is displaying a fault code related to circulation or pressure differential.
Cause: The control unit detects that there is not enough flow and blocks the boiler for safety reasons to avoid damaging the heat exchanger.
Before changing the pump, bleed the circuit well and make sure that the radiator valves are not closed.
Ferroli fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| A03 | Overtemperature protection activation. | If the circulating pump (ref. 39820902) is blocked/faulty or does not start, the water does not circulate and the primary overheats. Check order/voltage at terminals, ensure the rotor turns, and bleed the circuit. |
| F43 | Activation of the heat exchanger protection. | A null or very low circulation due to pump fault/blockage activates the heat exchanger protection. Check the power supply and rotation of the pump and ensure there is flow in the primary circuit. |
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.
