How to check if ref. 61301964 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 61301964. 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 circulation pump 61301964 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 are not heating up and the water is not circulating, even though the boiler is on.
Cause: If the pump does not move the water, the heat does not reach the radiators.
Make sure that the zone valves and the radiator valves are open before checking the pump.
- 02
The pump does not start or stops quickly.
Cause: A stuck impeller or the motor's thermal protection stops the pump to prevent damage.
With the cold installation, try to manually release the shaft through the front slot and attempt to start again.
- 03
There is noise, vibration, or buzzing coming from the pump while it is operating.
Cause: Air in the circuit or low pressure causes the pump to cavitate and vibrate while rotating.
Bleed the circuit and check the pressure on the manometer before replacing the pump.
- 04
There is a water leak from the pump shaft.
Cause: The mechanical seal of the shaft wears out over time and may start to leak, even if the motor is functioning correctly.
Dry the area and check after a period of use if the leak continues to come from the shaft.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 60-70-80 | Lack of water circulation | The circulating pump/air separator (stuck, seized, with air or without power) prevents the primary flow and triggers this code; check 230 V at the pump, bleed the circuit, and release/confirm shaft rotation from the front cap. |
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.
