How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Locate the pump label. It should read "Réf 4022 3080.38/0" and the model NFSL12/5-HE-1 C.
- Check the number 4515443 and the additional code 1199530, marked on the part.
- Check the electrical data on the label: ~230 V-50 Hz, 0.34 A / 77 W, 2 µF capacitor, class H, IP44, TF95.
- Compare the appearance with your pump: gray metal motor, black hydraulic body, orange cap on the top, and electrical connection via plug.
- Do not confuse it with the similar references and codes in the "Do not confuse" section (4513554, 4215540, 4022.3080.29, BI1352100): always compare the complete model and the reference.

Symptoms that require diagnosis in the circulation pump
The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
In the Minox Eco 24 E, the heating pump never stops.
Cause: The pump can be set to ON mode (always running). By default, it operates in TA mode, under the control of the room thermostat.
Check the pump mode setting in your boiler's user instructions. If it is set to ON, switch it back to TA before considering a fault.
- 02
In the Minox Eco 24 E, the pump continues to run for a while when the boiler stops heating.
Cause: It is the post-circulation of heating. It is regulated around 1 minute and can be adjusted from 0 to 4 minutes.
If the time is greater than 4 minutes or the pump does not stop, check the mode (TA or ON) and the adjusted post-circulation time.
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.
