How to check if ref. R10024975 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 R10024975. 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 circulator pump R10024975 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 ignites and operates, but the radiators do not heat up.
Cause: The circulator is not pushing water to the circuit, so the heat is not coming out of the heat exchanger.
Check if the pump speed selector is in a middle or loose position: set it to maximum before considering the pump faulty.
- 02
The pump does not start even though it is receiving power.
Cause: The rotor may be stuck, which is common if the boiler has not been used for heating for months.
With the boiler turned off, try turning the shaft with the front unlocking screw before replacing the part.
- 03
Noticeable noise or vibration when starting the pump.
Cause: It could be due to air in the circuit or cavitation caused by low pressure in the system.
Check the pressure gauge of the boiler and bleed the circuit before concluding that the pump is damaged.
- 04
Water is leaking from the area where the pump body connects to the motor.
Cause: The mechanical seal of the shaft has worn out and has lost its tightness.
Dry the area and check in cold if the dripping reappears after a while of operation.
Fault codes for Beretta that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 71 | PRIMARY SENSOR (T) | If the circulating pump is blocked or faulty, there is no flow in the primary; the flow temperature rises quickly, and the boiler detects an overtemperature at the flow sensor (71). Check the power supply to the pump, the start/rotation of the rotor, and ensure there is actual circulation (valves open, no air). |
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.
