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.
- Check the rating plate of your boiler. It should say Biasi Myto Condens Inox 24 or Inox 35. If it is another model, please consult us before ordering it.
- Locate the label of the pump. It should say Wilo Yonos PARA NFSL12/6B-PWM1 W MC and the code 4527883. If yours has a "Référence" label, it should say 4022.3080.82.
- Compare the label data: 1~230 V, 50/60 Hz, 3-41 W, 0.36 A, IPX4D, PN6, and TF95. The 1706109 is an additional marked code and the 17W08 is the date/batch code.
- Do not rely on the name "NFSL 12/6" alone. There are similar pumps with different codes (4520922, 6281894, 2126554004). Compare the full model and 4527883.
- The pump operates at 230 V and is part of the water circuit. Have it replaced by a qualified technician.
- Any questions? Send us a photo of your pump's label and the boiler's PCB from the Contact section, or call 911 17 77 77.

Before purchasing
- Not valid for Biasi Myto Condens 24 and 35 (2010.03), version without "Inox": it uses another pump (Wilo 12/5, no. 4520922)
- Do not confuse with 4520922: Wilo pump INTNFSL12/5 HE-1 (Biasi BI1462103). It is a model 12/5, not the NFSL12/6B-PWM1 W MC, and it does not correspond to 4527883.
- Do not confuse with BI1272100: Wilo WSC NFSL 12/5-1 HE CRF9S pump (Biasi 280.90.0033). It is a different model (12/5-1 HE CRF9S), not this pump.
- Do not confuse with 6281894: Wilo NFSL 12/6 pump for Hermann boilers. It is a different order number and does not correspond to 4527883.
- Do not confuse with 2126554004: Wilo NFSL 12/6 pump with another catalog number. It does not correspond to 4527883.
- Do not confuse with NFSL 12/6 RKC: Yonos FOR NFSL 12/6 with Red Knob control (RKC). The model of this pump ends in PWM1.
- Contact us before purchasing if your boiler is: Biasi Rinnova Condens 24.
