Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F43Activation of the heat exchanger protection.A blocked circulation pump (ref. 39818450) or one without flow prevents water circulation and overheats the heat exchanger; the boiler triggers F43. Check that the pump receives voltage, rotates freely, delivers flow, and bleed the air from the circuit.
A03Overtemperature protection activation.If the circulation pump does not move the water, the flow temperature rises quickly and activates the overtemperature protection. Check the pump's power supply and consumption, ensure the shaft is not seized, and verify there is actual circulation (bleed/filters).
How do I know if this circulating pump is the one for my boiler?
Verify the reference 39818450 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Wilo part.
What is it used for?
The circulating pump circulates the water through the heating circuit.
Noise, water not circulating, or cold radiators?
Typical symptoms: humming, seized rotor after a long stop, or radiators that do not heat evenly.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Bleed the air from the circuit and the pump; check the pressure at 1–1.5 bar with the boiler cold.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
