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.
- Look at the label on the motor head, the round part with the Wilo logo. It should say "Typ NFSL12/6 HEP-1 C" and "N° 4517157".
- Check that the same label indicates ~230 V-50 Hz, 0.37 A, 83 W, class F, PN6, TF95, IP44, and 2.6 µF, and that it carries the commercial reference 4022.3080.40. The code 0954027 is also marked on the part.
- Don't just stick to "NFSL 12/6" as is. There are other variants (for example, HEP-1 CRF 12 WIT) and other NFSL 12/6 pumps with different numbers. Yours should end in HEP-1 C.
- Check the rating plate of your boiler to see if it is a Biasi Minox Eco 24E, Minox Condens 24E, Minox Condens 24 ES, or Malia 28E.
- Compare the black hydraulic body and the orange plug with the photos in the technical sheet.
- If you have compatibility questions, call us at 911 17 77 77 or send us a photo of the pump label and the boiler PCB from the Contact section.
