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 for the number 480080038401 on the pump casing and the code PY-51NDEUA3 on its label. The model is ECPY51PWMEUC1.
- Also compare the printed code QZEZECP-F1 and the values on the label: 325 VDC, 7–44 W, PN6, IP X2.
- For the Clas One 24, you need the 65116908-03 and an official breakdown that provides the Wilo 65104319: always compare the printed code on your pump, not just the boiler model.
- Check on the PCB of your boiler that it is an Ariston Clas One 24, the one you have confirmed, and note its model code.
- If they match, call us at 911 17 77 77 with the model of your boiler.

Before purchasing
- Ariston Genus One 24 / 30 / 35 — and (same sheet, 1 origin)
- Ariston Genus One System 24 / 30 / 35 — and (same sheet, 1 origin)
- To confirm: Ariston Alteas One Net 24 / 30 / 35 — (24, 30, and 35) and (24): same technical sheet, 1 origin.
- Do not confuse: 65104319 — Wilo Pump (POMPA 5M 2V WILO) which the official breakdown R8203482-03 (14/06/2018) provides for the Clas One 24 (3301017) — Another pump, without the codes for this part. If your boiler has that revision, compare the printed code on your pump.
- Do not confuse: 60002375 — Ariston Yonos Clas One pump, which is for 30 kW models (Clas One L 30, Clas Premium Evo L 30) — Another pump: in which we could read none of the list for a Clas One 24, and it does not include the codes for this part.
- Only one Ukrainian sheet (repeated) unites 480080038401 and ECPY51PWMEUC1 with the article 65116908. Not confirmed: PY-51NDEUA3 or QZEZECP-F1: these are the marked ones of the part, confirmed. Compare them with those of your pump.
- Same technical sheet in Ukrainian (and: same title, codes, and price): 1 origin, possible copy. Quote ECPY51PWMEUC1 in the general list of boilers (includes "CLAS ONE", without 24), without equivalence. Not confirmed: the Clas One 24 with them.
Frequently asked questions: Ariston
Where is the code for the Ariston ECPY51PWMEUC1 pump and what other marking should I compare?
The casing has the number 480080038401 printed on it and the part label has the code PY-51NDEUA3. The model is ECPY51PWMEUC1 and there is another printed code, QZEZECP-F1. Compare the four with those of your pump, with or without spaces (480 080 038 401, ECPY 51 PWM EUC1).
Is it compatible with my Ariston Clas One 24?
Yes. Confirmation registered: this pump for the Ariston Clas One 24. Additionally, from the UK and Italy, they provide for Clas One 24 models the pump 5M PWM TACO 65116908-03, although none mention 480080038401 or ECPY51PWMEUC1. The Ukrainian sources that reference your codes do not list the Clas One. They mention ECPY51PWMEUC1 in a general list of boilers that includes "CLAS ONE," without any relation to this pump. Compare the printed code of your pump.
Is it compatible with other Ariston boilers, such as Genus One or Alteas One Net?
It is yet to be confirmed. Ukrainian models with almost identical text provide article 65116908, with 480080038401 and ECPY51PWMEUC1, for Genus One 24/30/35, Genus One System 24/30/35, and Alteas One Net 24 (also 30 and 35). It is the same sheet in Ukrainian, so it counts as a single source. Send us a photo of your pump label and the boiler's PCB from Contact, or call us at 911 17 77 77.
What do 480080038401, PY-51NDEUA3, ECPY51PWMEUC1, QZEZECP-F1, and 65116908 mean?
To confirm: 480080038401 is the number printed on the casing (motor code). PY-51NDEUA3 is the label code, ECPY51PWMEUC1 is the model, and QZEZECP-F1 is an additional printed code. 65116908 is the Ariston item (pump 5M PWM TACO) with which Ukrainians list 480080038401 and ECPY51PWMEUC1, with 325 VDC, PN6, and class E, as per the label.
Is the pump the same as the 65116908-03, the Wilo 65104319, or the Yonos 60002375?
La 65116908-03 comparte número base con la 65116908; la ficha dice que sustituye a la -02 y a la -01, pero sin confirmación adicional la une a tus códigos. La Wilo 65104319 y la Yonos 60002375 son otras bombas: la primera es la que da un despiece oficial para la Clas One 24 (3301017); la segunda, italianas para modelos de 30 kW. Compara el código impreso.
What do the official breakdowns of the Clas One say about its pump?
They do not match. The R8203482-03 (14/06/2018) gives the Wilo 65104319 in position 0604 for the Clas One 24 (3301017). The R8203484-03 (12/10/2017) lists the TACO 5M PWM 65116908 and the Yonos 60002375 in that position, but the text does not clarify which brand belongs to the Clas One 24. Neither mentions the codes for this part. For your boiler, what has been confirmed is valid: compare your pump and the model code of your PCB.
Who should install it?
A qualified technician is advisable: the pump operates at 325 VDC according to its label.
