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.
- Read the label of the pump: it should say "Yonos FOR PWM1" and the model SD15/6B PWM1; the reference is 4527535.
- Compare 4527535, 0020199706, and 495877: they appear in our pump and in the other one. In the unit, the PCB shows 22W26 2216614 and the label 90 2226 and 010565T: they do not match those of our spare part, which they send.
- The 495877 is also listed under another part (0020207133) that includes the pump 4526142 SD15/7.0 iPWM1 W MC. To distinguish them, compare the control (PWM1 versus iPWM1) and the power (3–41 W versus 3–45 W).
- Do not confuse it with the motor 0020207133 or the box 0020207140 from the Semiafast Condens 30 - A catalog: they could not be connected to this pump.
- If they match, call us at 911 17 77 77 with the model of your boiler and we will let you know if we have it.
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
F.20 in the Thema Condens AS 30-A (H-ES): safety disconnection due to temperature limiter
Cause: The Saunier Duval manual table lists "blocked pump" and "presence of air" among the causes. Check if the pump is running and if there is air in the circuit before replacing it.
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.

Before purchasing
- To confirm: De Dietrich MCA 15/25/35: the appointment with this pump
- Not compatible or excluded: Saunier Duval Semia C/F — with another pump: Wilo HB 15/4-1
- Not compatible or excluded: Saunier Duval Themaclassic F25/24E — with another pump: motor UPS15-50-AO (SD10052-R)
- Do not confuse: 0020207133 — Pump motor from the Semiafast Condens 30 - A catalog — In the text read from the catalog (part of the PDF), 4527535 and the codes on this label do not appear: we do not consider it as equivalent.
- Do not confuse: 0020207140 — Pump box R-SD from the same catalog — It is the pump box, another part.
- Do not confuse: 90 1542 — Text "Yonos FOR iPWM1 90 1542 495877" from another part (body 0020207133) — lists the pump 4526142 SD15/7.0 iPWM1 W MC (3-45 W, 0.44 A): another variant, not this PWM1 (3–41 W, 0.36 A). Shares the 495877.
- The catalog of the Semiafast Condens 30 - A lists the pump motor as 0020207133, but in the text read (part of the PDF), neither 4527535 nor the codes on this label appear: we do not consider that equivalence valid.
- Workshop: Semia Condens 30-A, Thema Condens AS 30-A (H-ES) and Thema Condens 25-A (H-ES) R2. External: une 4527535 with the model SD15/6B PWM1 W MC; as read, Not confirmed: the pump with those boilers.
Frequently asked questions about the circulation pump
Where is the code for this pump and what does each one mean?
The commercial reference is 4527535 and the model is Yonos PARA SD15/6B PWM1 W MC; list 4527535 as the "manufacturer code" for that model. On the part's PCB, it reads 16W40 and 1622792; the secondary label carries 90 1640, 0020199706, 495877, and 060161 T4, and a coupled component marked 0020201781. The unit shares 4527535, 0020199706, and 495877, but is marked 22W26 2216614 and 90 2226. Without additional confirmation, explain the rest of the codes.
Is it compatible with my Saunier Duval Semia Condens 30-A, Thema Condens AS 30-A (H-ES) or Thema Condens 25-A (H-ES) R2?
Yes. Confirmation registered: this pump for the Semia Condens 30-A, the Thema Condens AS 30-A (H-ES), and the Thema Condens 25-A (H-ES) R2. As read, Not confirmed: 4527535 with those boilers: it only places it in OEM equipment of the brand, without model. The manual for the Thema Condens AS 30-A (H-ES) describes a modulating pump controlled by PWM from the PCB (d.15). For another model, send us a photo of your pump's label and the boiler's PCB from Contact, or call 911 17 77 77.
Is the 0020207133 from the spare parts catalog this pump?
We don't know. The spare parts catalog for the Semiafast Condens 30 - A (2015 PDF) lists 0020207133 as "Moteur de pompe" (pump motor), but in the text read (part of the PDF), neither 4527535 nor the codes from the label appear. Another sheet describes it as the pump body of the ThemaClassic C25. Compare the motor marking before ordering it.
Can it be confused with another Yonos PARA of 3-45 W?
It is not the same. From another part (body 0020207133), list the pump 4526142 SD15/7.0 iPWM1 W MC with 3-45 W and 0.44 A, along with the text "Yonos PARA iPWM1 90 1542 495877". This SD15/6B PWM1 W MC is rated at 3-41 W and 0.36 A, values that are repeated. The 495877 appears in both texts: compare the type (PWM1 or iPWM1) and the maximum current.
What technical data does it have?
To confirm: PWM1 control, from 3 to 41 W and a maximum of 0.36 A, at 1~230 V and 50/60 Hz, PN6, TF95, IPX4D and EEI ≤ 0.21 (part 3). Confirm 3–41 W, 0.36 A, IPX4D and PN6, and add up to 95 °C and insulation class F; its EEI (≤ 0.20) differs and prevails the...
Does it fit in other boilers besides the confirmed ones?
quote 4527535 in OEM equipment with PWM1 from Viessmann, Vaillant, and Saunier Duval, in De Dietrich MCA 15/25/35 and in Sime versions with MC body: it is a single one and remains to be confirmed. We do not consider it compatible with the Semia Condens F24 E and F30 E: their manual describes a 3-speed pump (I, II, and III) with a selector (section 7.1), and this is PWM1.
Who should install it and what should be taken into account?
A qualified technician: works at 230 V and is in the water circuit. The manual for the Semia Condens F30 E (another model) indicates to close the supply and return valves, open the drain valve next to the pump (it is not necessary to drain the entire circuit), disconnect the connector, and use only new O-rings and gaskets.
What is the exact reference?
Wilo Yonos FOR SD15/6B PWM1 W MC, reference 4527535.
What control and power supply does it use?
PWM1 control; 1~ 230 V, 50/60 Hz, 3–41 W and maximum current 0.36 A.
