How to check if ref. 0010030642 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 0010030642. 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 0010030642 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 radiators take a long time to heat up or remain lukewarm even though the boiler is working.
Cause: The pump is not moving enough water because the impeller is not spinning properly or there is air in the circuit.
Set the pump to high speed and bleed the circuit before replacing it.
- 02
A continuous gurgling or buzzing sound is heard in the area of the pump.
Cause: Air trapped in the impeller does not always indicate that the motor is faulty.
Bleed the pump's bleeder, which is usually a screw in the center of the rotor, before considering that the part is faulty.
- 03
The pump does not start when requesting heating, or it starts and stops by itself.
Cause: The motor may have a fault in the winding or the shaft may be seized.
Measure with a multimeter if power is reaching the pump before replacing it; if there is no power, the problem may be in the PCB or the wiring.
- 04
Moisture or a water ring appears at the base of the pump.
Cause: The mechanical seal of the shaft has lost its tightness over time.
Dry the area and check after a cycle of operation if the leak reappears at the shaft.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.20 | Safety shutdown: temperature limiter. | The circulating pump (ref. 0010030642) blocked/seized or without flow causes overheating of the primary. Check that the rotor is turning (front cap), that it is receiving power/signal, and that there is circulation (ΔT flow/return). |
| F.23 | Safety shutdown: excessive temperature variation. | Lack of circulation due to pump (0010030642) being blocked or with low performance quickly increases the flow/return difference. Check the pump's rotation/consumption and bleed air; observe anomalous ΔT in flow/return. |
| F.24 | Safety shutdown: temperature increase too rapid. | The circulating pump (0010030642) is not moving enough flow and the water heats up very quickly. Check that the pump is rotating/pumping, bleed the circuit, and confirm adequate pressure. |
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.
