How to check if reference 59915402 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Look for the plate on your pump: it should say Grundfos UP 15-50 AO and the P/N 59915402.
- Compare the data from the PCB: 230 V, 50 Hz, 90 W, 0.39 A, 2 µF capacitor, IP42, TF95, class H, and 6 bar. The production code of this unit is PC 0147CY.
- Don't rely solely on the model: there is another Grundfos reference for the UP 15-50 A0 (59994584) and lists with 61301964 for the MX2 24 FF. Compare the complete P/N.
- Check on the PCB of your boiler that it is a Chaffoteaux MX2 24FF or MC2 24FF.
- If they match, call us at 911 17 77 77 with the model of your boiler.
Symptoms that require diagnosis in the circulation pump 59915402
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 pump does not start.
Cause: Please confirm: Check the working capacitor (2 µF): it indicates that its condition directly affects whether the motor starts.
- 02
The heating is not working and the boiler is locking out due to lack of flow.
Cause: Absence of water flow in the circuit, often due to a seized pump, dirty filter, or closed valves.
Bleed, open the valves, and check the filter. If the pump does not turn or the water does not circulate, have a technician check it.
- 03
The boiler locks due to overheating (fault code 80).
Cause: Overtemperature of the circuit; often lack of circulation due to a seized pump.
Check that the pump is circulating and that the valves are open. Have a technician check it if the fault code returns.
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.

- Pending applications to verify
- The compatibility of ("MX2 24FF" and "MC2 24FF") comes from a handwritten warehouse card; it is not confirmed with the pump label or.
- Do not confuse: 59994584 — Reference for the Grundfos UP 15-50 A0 (with 2000801896, AWB/Glowworm); another listed as Glowworm pump for 24CI and 18SI — Same model, different reference: without additional confirmation, it is equated to 59915402.
- Do not confuse: 61301964 — Chaffoteaux reference for the pump + air separator 15/50 ("PUMP + AIR SEPARATOR 15/50" in English, "POMPE + DEGAZEUR 15/50" in French). for the MX2 24 FF and a single one, for the MC 2 24 FF N BE — It is another code and without additional confirmation read, it links it to 59915402. Another describes it as Grundfos UPR 15-50-F with two speeds (P1 70 W) and another as Grundfos circulator: compare the PCB, not just the description.
- Do not confuse: 65119656-01 — Pump head UPMO 60PH (Grundfos, for Chaffoteaux boilers), which a list for the MX2 24 FF lists as a substitute for 61301964 — Another code and another model (UPMO 60PH, not UP 15-50 AO); without additional confirmation, it links it to 59915402.
- 59994584 as a reference for the UP 15-50 A0. 61301964 for the MX2 24 FF. One also places it in the MC 2 24 FF N BE, and one gives 65119656-01 as its substitute. They are different codes: compare the complete P/N.
- Parts, codes, and boilers confirmed. Outside, link P/N 59915402 with UP 15-50 A0; another gives 59994584 as a reference for that same model and three provide 61301964 for MX2 24 FF. None mention 59915402 with MX2 24 FF or MC2 24 FF.
