How to check if ref. 20002906 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

- 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 circulator pump 20002906
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 ignites, but the radiators are cold or take a long time to heat up.
Cause: The water is not circulating properly because the pump rotor is not spinning.
Touch the pump to see if it vibrates or is hot: if you don't notice any movement, try to unlock it with the front screw before replacing it.
- 02
The pump makes a buzzing sound but does not start.
Cause: The rotor is stuck, probably due to limescale or rust accumulated after a period of disuse.
With the boiler turned off, use a flat screwdriver on the front screw to try to turn the shaft and release it.
- 03
There is rattling or vibration in the area of the pump when the heating is turned on.
Cause: It could be due to air in the circuit or because the rotor is rubbing unevenly.
Bleed the radiators and the pump bleeder before considering it a spare part issue.
- 04
There is moisture or dripping at the base of the pump.
Cause: The shaft seal is worn out and no longer seals the water properly.
Dry the area and check in cold if the dripping returns after a while of use, to ensure that it is coming from the shaft and not from a nearby fitting.
Beretta fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| A02 | The boiler shuts down due to overheating. | If the circulation pump is blocked or not working, the water does not circulate properly and heats up too quickly, activating the safety system. Check that the pump is receiving power and that the shaft rotates freely. If the supply water is much hotter than the return water, it is likely that the pump is not circulating properly. |
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.
