Symptoms that require diagnosis in the circulator pump 0010030688
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 heating water comes out lukewarm and the radiators do not fully heat up.
Cause: The pump is not generating enough pressure because the impeller is spinning loosely.
Check the pressure of the installation on the manometer before assuming that the pump is faulty.
- 02
The boiler makes a buzzing or vibrating noise that is especially noticeable when the heating is on.
Cause: There may be air trapped in the pump or the impeller is worn, which causes that noise when it spins.
Bleed the air from the circuit using the bleed valve on the pump before replacing it.
- 03
The pump does not start when heating is requested, and the boiler ends up showing a fault.
Cause: The motor cannot move the impeller because it is jammed, so the boiler does not detect circulation and locks out.
Try to manually unlock the shaft using a screwdriver in the rear slot of the motor before replacing it.
- 04
After a period of not using the boiler, the pump remains stopped and does not respond.
Cause: Lime has accumulated inside and has seized the shaft because the water has not moved for a long time.
Manually force the impeller to turn; if it releases just with that, you don't need to replace the part.
Fault codes Saunier Duval that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F.23 | The boiler shuts down for safety: large temperature difference between supply and return. | This symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement. |
| F.24 | The boiler shuts down for safety: the temperature rises too quickly. | This symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement. |
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.
