Grundfos Circulating Pump Chaffoteaux MC 2 24 FF P/N 59915402
Grundfos UP 15-50 A0 circulator pump mounted on Chaffoteaux boilers (MC 2 24 FF, Aludra Delta, Balixia, Calydra, Compy MX2, Elexia Comfort, Maya, Mira, MX2, Niagara Delta). It moves the water of the heating circuit between the boiler and the radiators. Replacement requires first confirming the fault of the part through technical diagnosis, even when it does not start, makes noise, leaks from the shaft, or the boiler does not heat with the burner on.

How to check if ref. 61301964 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- 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 that require diagnosis in the circulator pump 61301964
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 turns on and the burner works, but the radiators do not heat up.
Cause: The pump is not moving the water in the circuit even though the heat exchanger is heating.
Make sure the shaft rotates freely by turning it by hand through the front slot of the motor before replacing it.
- 02
A constant buzzing or vibrating sound is heard in the pump.
Cause: The impeller is spinning with friction, or there is air in the circuit and the motor has to work harder to overcome that resistance.
Bleed the air from the circuit using the nearest bleed valve and check if the noise decreases before replacing it.
- 03
A leak or water ring appears under the body of the pump.
Cause: The mechanical seal of the shaft has lost its tightness and is allowing water to pass through slowly.
Dry the area, turn on the heating, and locate whether the leak comes from the shaft or from a gasket of the casing before purchasing it.
- 04
The pump does not start when the heating is turned on.
Cause: The winding is not receiving current or the rotor is blocked and cannot start.
With the boiler turned off and cold, try turning the shaft by hand through the front slot to rule out that it is stuck.
Chaffoteaux fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 60-70-80 | Lack of water circulation | The circulating pump (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.
